As bleeding disorders are increasingly recognized as a national health priority, hematologists are focusing on how the patient-centered medical home – a widely accepted concept in primary care and in some specialties – can improve outcomes and quality life for their patients.

The patient-centered medical home is a model of health care delivery in which patients receive comprehensive, accessible care that is fully integrated across all providers and elements of a healthcare system.¹ The concept emerged in the 1960s among pediatricians seeking to better coordinate care for children with complex medical needs. Since then, the patient-centered medical home has become a globally recognized standard – not only in primary care, but also in specialties such as endocrinology, oncology, and geriatric medicine. The movement to establish medical homes for patients with bleeding disorders is more recent and is receiving national attention.

Why a medical home?

The advent of prophylactic therapies for bleeding disorders has vastly improved the outlook for many patients compared to just a few decades ago. However, treatment options remain limited, and patients who have severe disease or complications – such as an inadequate treatment response or the development of inhibitory antibodies to replacement clotting factors – are at risk for recurrent breakthrough bleeding that can lead to synovitis and ultimately culminate in progressive, irreversible joint damage. The resulting pain and limitation of motion greatly compromises patients’ quality of life across physical, psychological, and social domains, undermines their ability to live and work independently, and greatly increases treatment costs.^2-4 Family members, too, face high stress and lower quality of life when they struggle to obtain and manage treatment while caring for loved ones with bleeding disorders.⁵

For patients with bleeding disorders, a patient-centered medical home can help address or surmount these challenges, said Amy Shapiro, MD, medical director of the Indiana Hemophilia and Thrombosis Center in Indianapolis, Ind., which was the first hemophilia treatment center in the country to be formally certified as a medical home.

Dr. Shapiro explained that a patient-centered medical home leverages the care of an integrated multidisciplinary team to help optimize therapies and patient outcomes across all domains of life. She sees the medical home concept as a natural fit for patients with bleeding disorders, given the complexity of their needs and the number of specialties involved. “When you have hemophilia, you don’t just need a hematologist to manage your care. You need nurses, physical therapists, and social workers. You need coordinated care for genetic counseling. You also need to coordinate dental hygiene and surgical interventions, if these are required. Patients need nutrition counseling, and they may need assistance with education or career options if too many days are missed from work or school. Patients or their families may need counseling on choosing the right insurance program so they don’t choose a plan that may create more hardships for them because of their chronic disorder.”

Meeting these needs requires the help of an integrated care team, which many individuals with bleeding disorders lack. “If you are just out there in the community and you have medical issues that need to be dealt with, often the individuals themselves have to coordinate their own care, including their medications and their appointments with different specialists,” said Dr. Shapiro. “For example, a care provider may tell a patient that they need a physical therapist and give them some names, and then the patient has to take it from there and not only find the provider, but also determine if their insurance provides coverage.”

A medical home takes a completely different approach, she explained. “At my center, when we say you need a physical therapist, we have a physical therapist on staff. Our therapist provides an assessment and determines the need for ongoing PT and whether that can be done at home with a plan and intermittent oversight, or whether the patient needs a referral, and whether the person the patient is referred to needs education on how to provide PT for someone with hemophilia. A medical home provides all this in one place. It is a place where patients know they will receive either direct services, or support to shepherd their care and outcomes, and oversight of that support as well.”

Few studies have directly assessed the medical home model in the setting of bleeding disorders, but a number have evaluated the impact of integrated care, a more general term for the practice of coordinating multidisciplinary care to improve access and outcomes while eliminating redundancies and unnecessary costs. In a recent systematic review and meta-analysis of 27 nonrandomized studies of patients with hemophilia, integrated care was linked to lower mortality, fewer emergency room visits and hospitalizations, shorter lengths of stay in the hospital, and fewer missed days of school and work.⁶ Such findings, combined with promising outcomes data from studies of patient-centered medical homes in other disease settings, suggest that the patient-centered medical home can significantly benefit patients with bleeding disorders and their families and caregivers.
 

Creating a medical home

Establishing a patient-centered medical home can be challenging, involving a plethora of stakeholders and a considerable investment of time, energy, and resources. Organizations such as the National Committee for Quality Assurance and the Accreditation Association for Ambulatory Health Care have formal certification programs to help ensure that an inpatient or outpatient center that calls itself a medical home truly is one.^7-8

The certification process requires centers to document activities in areas such as patients’ rights and responsibilities, administration and governance, patient and care team relationships, clinical records and other health information, and quality, comprehensiveness, continuity, and accessibility.⁷ Achieving certification is rigorous, often requiring centers to document compliance with more than 100 policies, procedures, and standards.

For the Indiana Hemophilia and Thrombosis Center, becoming certified as a medical home “was a multiyear process and an ongoing process,” said Dr. Shapiro. “It involves documentation of quality improvement initiatives, obtaining input from patients to document their satisfaction, and looking at all types of systems within our center and how we integrate care so that all those systems function together. It’s a difficult process, but treatment centers are a medical home for patients with bleeding disorders, and this is an effort to provide some documentation on a national level of how we’re doing everything that we are doing.”

She noted that the process of obtaining medical home certification may require an even higher level of commitment if a bleeding disorder (hemophilia) treatment center is embedded in a university or academic medical center. In this case, more stakeholders are involved, and more hoops may need to be jumped through to implement processes that meet medical home standards while still adhering to any requirements at the organizational level.

Certification programs for patient-centered medical homes are not designed around specific disorders or diseases, but a closer look at their compliance metrics underscores how medical homes can benefit patients with bleeding disorders. For example, to receive medical home certification from the Accreditation Association for Ambulatory Health Care, a center needs to be able to document that patients’ care is not transferred without first making arrangements with a receiving health care provider, that the quality improvement programs are peer-led, and that these programs assess and address diverse measures of clinical performance, cost-effectiveness, and administrative functioning.^7-9

Medical homes, the NHPCC, and Healthy People 2030

Creating patient-centered medical homes for patients with bleeding disorders is now a quality improvement objective of the National Hemophilia Program Coordinating Center, or NHPCC. Established in 2012 and funded by the federal Health Resources and Services Administration, the NHPCC partners with the eight regional hemophilia networks and more than 140 federally funded hemophilia treatment centers across the United States to identify gaps, standardize and improve access to care, and share and promote best practices for the treatment and management of blood disorders.¹⁰

In the United States, receiving care in a hemophilia treatment center (which, despite its name, typically offers care for other disorders such as von Willebrand disease) has been linked to lower mortality and fewer hospitalizations related to bleeding complications.¹¹ To continue to improve on these outcomes, the NHPCC, regional networks, and hemophilia treatment centers are prioritizing medical homes and ranking their establishments alongside core objectives such as bettering patient and family engagement and improving the transition from pediatric to adult care.¹²

As part of this quality improvement work, the NHPCC, regional leadership, and hemophilia treatment centers meet regularly to identify needs and priorities, plan programs, and ensure that each center is meeting the goals and objectives set out by its federal grant.¹³ Such partnerships help improve and integrate care within a coordinated national framework, Dr. Shapiro said. “We all are charged with this same mission,” she added. “That doesn’t mean that every treatment center looks exactly the same, has the same number of staff, or does everything the same way, but we all have the same mission, and we know what that is. That is the work of the NHPCC, to determine and document that and help level and improve care throughout the country.”

The NHPCC also engages other stakeholders, including consumer agencies and professional organizations. Recent achievements have included a first-ever national patient needs assessment, a tandem technical needs assessment of hemophilia treatment centers, an educational outreach program for genetic counselors, a webinar on transitioning care for adolescents, a national survey of the federal 340B Drug Pricing Program, and a survey of minority patients to identify and characterize problems such as language and insurance barriers, the lack of culturally appropriate educational materials on blood disorders, and difficulties getting transportation to treatment centers or educational programs.¹⁴

In part because of this advocacy work, the U.S. Department of Health and Human Services recently included hemophilia for the first time in Healthy People, its evidence-based set of decade-long objectives aimed at improving the health of all Americans. In Healthy People 2030, the specific objective for hemophilia is to reduce the proportion of patients with severe disease who experience more than four joint bleeds per year to 13.3% (the current estimate is 16.9%).¹⁵

For Healthy People to prioritize hemophilia for the first time alongside much more common conditions such as diabetes and heart disease reflects the challenges of managing bleeding disorders and the efforts by the NHPCC and other stakeholders to raise awareness about current needs. To track progress in meeting the Healthy People 2030 objective, the NHPCC will work with federal partners to analyze patient-level data gathered through the Centers for Disease Control’s Community Counts Registry for Bleeding Disorders Surveillance program, which collects data from hemophilia treatment centers across the United States and includes patients with all levels of disease severity.

“The inclusion of bleeding disorders in Healthy People 2030 is really very significant,” said Dr. Shapiro. “These are disorders that affect less than 200,000 Americans, which is the definition of a rare disease in this context. To have hemophilia considered as a national priority is very important, not only for hemophilia, but also for other rare diseases that may in the future also be considered as being as of national importance in this way.”

A rare, life-threatening anemia now has a new treatment option. The Food and Drug Administration announced the approval of pegcetacoplan (Empaveli) injection to treat adults with paroxysmal nocturnal hemoglobinuria (PNH). Pegcetacoplan is the first PNH treatment that binds to complement protein C3, according to the FDA announcement. Complement protein C3 is a key component of host immunity and defense.

Because of the risk of severe side effects, the drug is available only through a restricted program under a risk evaluation and mitigation strategy (REMS). Serious infections can occur in patients taking pegcetacoplan that can become life-threatening or fatal if not treated early. According to the FDA, REMS are designed to reinforce medication use behaviors and actions that support the safe use of that medication, and only a few drugs require a REMS.

The most common other side effects are injection site reactions, diarrhea, abdominal pain, and fatigue.

Pegcetacoplan was approved based upon a study of 80 patients with PNH and anemia who had been taking eculizumab, a previously approved treatment. During 16 weeks of treatment, patients in the pegcetacoplan group had an average increase in their hemoglobin of 2.4 g/dL, while patients in the eculizumab group had an average decrease in their hemoglobin of 1.5 g/dL.
 

About the disease

PNH is caused by gene mutations that affect red blood cells, causing them to be defective and susceptible to destruction by a patient’s own immune system. Red blood cells in people with these mutations are defective and can be destroyed by the immune system, causing anemia.

Other symptoms include blood clots and destruction of bone marrow. The disease affects 1-1.5 people per million, with diagnosis typically occurring around ages 35-40, and a median survival of only 10 years after diagnosis, according to the FDA.

A rare, life-threatening anemia now has a new treatment option. The Food and Drug Administration announced the approval of pegcetacoplan (Empaveli) injection to treat adults with paroxysmal nocturnal hemoglobinuria (PNH). Pegcetacoplan is the first PNH treatment that binds to complement protein C3, according to the FDA announcement. Complement protein C3 is a key component of host immunity and defense.

A majority of Mohs surgeons have adopted telemedicine during the COVID-19 pandemic, a new survey finds, but only half expressed interest in making it a permanent part of their practices.

A variety of factors combine to make it “very difficult for surgeons to make long-term plans for implementing telemedicine in their practices,” said Mario Maruthur, MD, who presented the findings at the annual meeting of the American College of Mohs Surgery. “Telemedicine likely has a role in Mohs practices, particularly with postop follow-up visits. However, postpandemic reimbursement and regulatory issues need to be formally laid out before Mohs surgeons are able to incorporate it into their permanent work flow.”

Dr. Maruthur, a Mohs surgery and dermatologic oncology fellow at Memorial Sloan Kettering Cancer Center, New York, and colleagues sent a survey to ACMS members in September and October 2020. “We saw first-hand in our surgical practice that telemedicine quickly became an important tool when the pandemic surged in the spring of 2020,” he said. Considering that surgical practices are highly dependent on in-person visits, the impetus for this study was to assess to what degree Mohs practices from across the spectrum, including academic and private practices, embraced telemedicine during the pandemic, and “what these surgical practices used telemedicine for, how it was received by their patients, which telemedicine platforms were most often utilized, and lastly, what are their plans if any for incorporating telemedicine into their surgical practices after the pandemic subsides.”

The researchers received responses from 115 surgeons representing all regions of the country (40% Northeast, 21% South, 21% Midwest, and 18% West). Half practiced in urban areas (37%) and large cities (13%), and 40% were in an academic setting versus 36% in a single-specialty private practice.

More than 70% of the respondents said their case load fell by at least 75% during the initial surge of the pandemic; 80% turned to telemedicine, compared with just 23% who relied on the technology prior to the pandemic. The most commonly used telemedicine technologies were FaceTime, Zoom, Doximity, and Epic.

Mohs surgeons reported most commonly using telemedicine for postsurgery management (77% of the total 115 responses). “Telemedicine is a great fit for this category of visits as they allow the surgeon to view the surgical site and answer any questions they patient may have,” Dr. Maruthur said. “If the surgeon does suspect a postop infection or other concern based on a patient’s signs or symptoms, they can easily schedule the patient for an in-person assessment. We suspect that postop follow-up visits may be the best candidate for long-term use of telemedicine in Mohs surgery practices.”

Surgeons also reported using telemedicine for “spot checks” (61%) and surgical consultations (59%).

However, Dr. Maruther noted that preoperative assessments and spot checks can be difficult to perform using telemedicine. “The quality of the video image is not always great, patients can have a difficult time pointing the camera at the right spot and at the right distance. Even appreciating the actual size of the lesion are all difficult over a video encounter. And there is a lot of information gleaned from in-person physical examination, such as whether the lesion is fixed to a deeper structure and whether there are any nearby scars or other suspicious lesions.”

Nearly three-quarters of the surgeons using the technology said most or all patients were receptive to telemedicine.

However, the surgeons reported multiple barriers to the use of telemedicine: Limitations when compared with physical exams (88%), fitting it into the work flow (58%), patient response and training (57%), reimbursement concerns (50%), implementation of the technology (37%), regulations such as HIPAA (24%), training of staff (17%), and licensing (8%).

In an interview, Sumaira Z. Aasi, MD, director of Mohs and dermatologic surgery, Stanford University, agreed that there are many obstacles to routine use of telemedicine by Mohs surgeons. “As surgeons, we rely on the physical and tactile exam to get a sense of the size and extent of the cancer and characteristics such as the laxity of the surrounding tissue whether the tumor is fixed,” she said. “It is very difficult to access this on a telemedicine visit.”

In addition, she said, “many of our patients are in the elderly population, and some may not be comfortable using this technology. Also, it’s not a work flow that we are comfortable or familiar with. And I think that the technology has to improve to allow for better resolution of images as we ‘examine’ patients through a telemedicine visit.”

She added that “another con is there is a reliance on having the patient point out lesions of concern. Many cancers are picked by a careful in-person examination by a qualified physician/dermatologist/Mohs surgeon when the lesion is quite small or subtle and not even noticed by the patient themselves. This approach invariably leads to earlier biopsies and earlier treatments that can prevent morbidity and save health care money.”

On the other hand, she said, telemedicine “may save patients some time and money in terms of the effort and cost of transportation to come in for simpler postoperative medical visits that are often short in their very nature, such as postop check-ups.”

Most of the surgeons surveyed (69%) said telemedicine probably or definitely deserves a place in the practice Mohs surgery, but only 50% said they’d like to or would definitely pursue giving telemedicine a role in their practices once the pandemic is over.

“At the start of the pandemic, many regulations in areas such as HIPAA were eased, and reimbursements were increased, which allowed telemedicine to be quickly adopted,” Dr. Maruther said. “The government and payers have yet to decide which regulations and reimbursements will be in place after the pandemic. That makes it very difficult for surgeons to make long-term plans for implementing telemedicine in their practices.”

Dr. Aasi predicted that telemedicine will become more appealing to patients and physicians as it its technology and usability improves. More familiarity with its use will also be helpful, she said, and surgeons will be more receptive as it’s incorporated into efficient daily work flow.

The study was funded in part by the National Institutes of Health.

Dual HER2 blockade with pertuzumab (Perjeta) and trastuzumab (Herceptin) on top of anthracycline-based neoadjuvant chemotherapy for early-stage breast cancer was associated with a low rate of clinically relevant cardiac events in the final follow-up of the BERENICE study.

After more than 5 years, 1.0%-1.5% of patients who had locally advanced, inflammatory, or early-stage breast cancer developed heart failure, and around 12%-13% showed any significant changes in left ventricular ejection fraction (LVEF).

Importantly, “there were no new safety concerns that arose during long-term follow-up,” study investigator Chau Dang, MD, said in presenting the findings at the European Society for Medical Oncology: Breast Cancer virtual meeting.

Dr. Dang, a medical oncologist at Memorial Sloan Kettering Cancer Centre in New York, reported that the most common cause of death was disease progression.

BERENICE was designed as a cardiac safety study and so not powered to look at long-term efficacy, which Dr. Dang was clear in reporting. Nevertheless event-free survival (EFS), invasive disease-free survival (IDFS), and overall survival (OS) rates at 5 years were all high, at least a respective 89.2%, 91%, and 93.8%, she said. “The medians have not been reached,” she observed.

“These data support the use of dual HER2 blockade with pertuzumab-trastuzumab–based regimens, including in combination with dose-dense, anthracycline-based chemotherapy, across the neoadjuvant and adjuvant treatment settings for the complete treatment of patients with HER2-positive early-stage breast cancer,” Dr. Dang said.

Evandro de Azambuja, MD, PhD, the invited discussant for the trial agreed that the regimens tested appeared “safe from a cardiac standpoint.” However, “you cannot forget that today we are using much less anthracyclines in our patient population.”

Patients in trials are also very different from those treated in clinical practice, often being younger and much fitter, he said. Therefore, it may be important to look at the baseline cardiac medications and comorbidities, Dr. de Azambuja, a medical oncologist at the Institut Jules Bordet in Brussels, Belgium, suggested.

That said, the BERENICE findings sit well with other trials that have been conducted, Dr. de Azambuja pointed out.

“If we look at other trials that have also tested dual HER2 blockade with anthracycline or nonanthracycline regimens, all of them reassure that dual blockade is not more cardiotoxic than single blockade,” he said. This includes trials such as TRYPHAENA, APHINITY, KRISTINE, NeoSphere and PEONY.

The 3-year IDFS rate of 91% in BERENICE also compares well to that seen in APHINITY (94%), Dr. de Azambuja said.
 

BERENICE study design

BERENICE was a multicenter, open-label, nonrandomized and noncomparative phase 2 trial that recruited 400 patients across 75 centers in 12 countries.

Eligibility criteria were that participants had to have been centrally confirmed HER2-positive locally advanced, inflammatory or early breast cancer, with the latter defined as tumors bigger than 2 cm or greater than 5 mm in size, and be node-positive. Patients also had to have a starting LVEF of 55% or higher.

Patients were allocated to one of two neoadjuvant chemotherapy regimens depending on the choice of their physician. One group received a regimen of dose-dense doxorubicin and cyclophosphamide (ddAC) given every 2 weeks for four cycles and then paclitaxel every week for 12 cycles. The other group received 5-fluorouracil, epirubicin, and cyclophosphamide (FEC) every 3 weeks for four cycles and then docetaxel every 3 weeks for four cycles.

Pertuzumab and trastuzumab were started at the same time as the taxanes in both groups and given every 3 weeks for four cycles. Patients then underwent surgery and continued pertuzumab/trastuzumab treatment alone for a further 13 cycles.

The co-primary endpoints were the incidence of New York Heart Association class III or IV heart failure and incidence of symptomatic and asymptomatic LVEF decline of 10% or more.

The primary analysis of the trial was published in 2018 and, at that time, it was reported that three patients in the ddAC cohort and none in the FEC cohort experienced heart failure. LVEF decline was observed in a respective 6.5% and 2% of patients.
 

Discussion points

Dr. de Azambuja noted that the contribution of the chemotherapy to the efficacy cannot be assessed because of the nonrandomized trial design. That should not matter, pointed out Sybille Loibl, MD, PhD, during discussion.

“I think it compares nicely to other trials that looked at dose-dense chemotherapy,” said Dr. Loibl, who is an associate professor at the University of Frankfurt in Germany. “It seems that, in the light of what we consider today probably one of the best anti-HER2 treatments, the chemotherapy is less relevant, and that’s why a dose-dense regimen doesn’t add so much on a standard anthracycline taxane-containing regimen.”

Dr. de Azambuja also commented on the assessment of cardiotoxicity and the use of reduced LVEF as a measure: LVEF decline is a late effect of cardiotoxicity, he observed, and he suggested a different approach in future trials.

“If you use Global Longitudinal Strain, this could be an optimal parameter to detect early subclinical LVEF dysfunction and you should consider it for the next trials looking for cardiac safety. Also, cardiac biomarkers. This was not implemented in this trial, and I strongly recommend this should be for the next trial.”

The BERENICE trial was funded by F. Hoffmann-La Roche. Dr. Dang disclosed receiving consultancy fees from F. Hoffmann-La Roche, Genentech, Daiichi Sankyo, Lilly, and Puma Biotechnology. Dr. de Azambuja was not involved in the study but disclosed receiving honoraria, travel grants, research grants from Roche and Genentech as well as from other companies. Dr. Loibl was one of the cochairs of the session and, among disclosures regarding many other companies, has been an invited speaker for Roche and received reimbursement via her institution for a writing engagement.

Dr. de Azambuja also commented on the assessment of cardiotoxicity and the use of reduced LVEF as a measure: LVEF decline is a late effect of cardiotoxicity, he observed, and he suggested a different approach in future trials.

“If you use Global Longitudinal Strain, this could be an optimal parameter to detect early subclinical LVEF dysfunction and you should consider it for the next trials looking for cardiac safety. Also, cardiac biomarkers. This was not implemented in this trial, and I strongly recommend this should be for the next trial.”

The BERENICE trial was funded by F. Hoffmann-La Roche. Dr. Dang disclosed receiving consultancy fees from F. Hoffmann-La Roche, Genentech, Daiichi Sankyo, Lilly, and Puma Biotechnology. Dr. de Azambuja was not involved in the study but disclosed receiving honoraria, travel grants, research grants from Roche and Genentech as well as from other companies. Dr. Loibl was one of the cochairs of the session and, among disclosures regarding many other companies, has been an invited speaker for Roche and received reimbursement via her institution for a writing engagement.

Dual HER2 blockade with pertuzumab (Perjeta) and trastuzumab (Herceptin) on top of anthracycline-based neoadjuvant chemotherapy for early-stage breast cancer was associated with a low rate of clinically relevant cardiac events in the final follow-up of the BERENICE study.

After more than 5 years, 1.0%-1.5% of patients who had locally advanced, inflammatory, or early-stage breast cancer developed heart failure, and around 12%-13% showed any significant changes in left ventricular ejection fraction (LVEF).

Importantly, “there were no new safety concerns that arose during long-term follow-up,” study investigator Chau Dang, MD, said in presenting the findings at the European Society for Medical Oncology: Breast Cancer virtual meeting.

Dr. Dang, a medical oncologist at Memorial Sloan Kettering Cancer Centre in New York, reported that the most common cause of death was disease progression.

BERENICE was designed as a cardiac safety study and so not powered to look at long-term efficacy, which Dr. Dang was clear in reporting. Nevertheless event-free survival (EFS), invasive disease-free survival (IDFS), and overall survival (OS) rates at 5 years were all high, at least a respective 89.2%, 91%, and 93.8%, she said. “The medians have not been reached,” she observed.

“These data support the use of dual HER2 blockade with pertuzumab-trastuzumab–based regimens, including in combination with dose-dense, anthracycline-based chemotherapy, across the neoadjuvant and adjuvant treatment settings for the complete treatment of patients with HER2-positive early-stage breast cancer,” Dr. Dang said.

Evandro de Azambuja, MD, PhD, the invited discussant for the trial agreed that the regimens tested appeared “safe from a cardiac standpoint.” However, “you cannot forget that today we are using much less anthracyclines in our patient population.”

Patients in trials are also very different from those treated in clinical practice, often being younger and much fitter, he said. Therefore, it may be important to look at the baseline cardiac medications and comorbidities, Dr. de Azambuja, a medical oncologist at the Institut Jules Bordet in Brussels, Belgium, suggested.

That said, the BERENICE findings sit well with other trials that have been conducted, Dr. de Azambuja pointed out.

“If we look at other trials that have also tested dual HER2 blockade with anthracycline or nonanthracycline regimens, all of them reassure that dual blockade is not more cardiotoxic than single blockade,” he said. This includes trials such as TRYPHAENA, APHINITY, KRISTINE, NeoSphere and PEONY.

The 3-year IDFS rate of 91% in BERENICE also compares well to that seen in APHINITY (94%), Dr. de Azambuja said.
 

BERENICE study design

BERENICE was a multicenter, open-label, nonrandomized and noncomparative phase 2 trial that recruited 400 patients across 75 centers in 12 countries.

Eligibility criteria were that participants had to have been centrally confirmed HER2-positive locally advanced, inflammatory or early breast cancer, with the latter defined as tumors bigger than 2 cm or greater than 5 mm in size, and be node-positive. Patients also had to have a starting LVEF of 55% or higher.

Patients were allocated to one of two neoadjuvant chemotherapy regimens depending on the choice of their physician. One group received a regimen of dose-dense doxorubicin and cyclophosphamide (ddAC) given every 2 weeks for four cycles and then paclitaxel every week for 12 cycles. The other group received 5-fluorouracil, epirubicin, and cyclophosphamide (FEC) every 3 weeks for four cycles and then docetaxel every 3 weeks for four cycles.

Pertuzumab and trastuzumab were started at the same time as the taxanes in both groups and given every 3 weeks for four cycles. Patients then underwent surgery and continued pertuzumab/trastuzumab treatment alone for a further 13 cycles.

The co-primary endpoints were the incidence of New York Heart Association class III or IV heart failure and incidence of symptomatic and asymptomatic LVEF decline of 10% or more.

The primary analysis of the trial was published in 2018 and, at that time, it was reported that three patients in the ddAC cohort and none in the FEC cohort experienced heart failure. LVEF decline was observed in a respective 6.5% and 2% of patients.

Among patients with locally advanced resectable esophageal or junctional cancer, the overall survival benefit conferred by preoperative chemoradiotherapy persists for at least 10 years, according to long-term results of the Chemoradiotherapy for Esophageal Cancer Followed by Surgery Study (CROSS). As a result of earlier publication of CROSS data, chemoradiotherapy followed by surgery has become one of the standards of care for patients with locally advanced resectable esophageal cancer, stated lead author Ben M. Eyck, MD, of Erasmus University Medical Center, Rotterdam, the Netherlands, and colleagues in the Journal of Clinical Oncology.

In the multicenter, randomized trial, initiated in 2004, 178 patients randomized to chemoradiotherapy with subsequent surgery and 188 patients randomized to surgery alone were followed with overall survival as the primary, and cause-specific survival and risks of locoregional and distant relapse as the secondary endpoints. Chemoradiotherapy consisted of 5 weekly cycles of carboplatin (area under the curve of 2 mg/mL/min) and paclitaxel (50 mg/m² body surface area on days 1, 8, 15, 22, and 29) with concurrent radiotherapy (41.4 Gy in 23 fractions, 5 days per week. Mean age was 60 years (around 78% male), with squamous cell carcinoma (23%) and adenocarcinoma (75%) as the predominant histologies.

The first analysis showed low short-term toxicity and 2-year survival increased from 50% for patients receiving surgery alone to 67% for neoadjuvant chemoradiotherapy plus surgery. Five-year follow-up data were consistent with initial reporting. Long-term benefits and harms of this regimen remain unclear, according to the researchers. Neoadjuvant chemoradiotherapy’s side effects could lead to long-term death from other causes than esophageal cancer, and may not be preventing but rather merely postponing cancer-related death. The aim of the current analysis was to determine whether the observed benefits persisted beyond 5 years.

As of Dec. 31, 2018, 117/178 patients in the chemoradiotherapy-surgery arm and 144/188 in the surgery arm had died. Median follow-up for surviving patients was 147 months. Patients in the chemoradiotherapy surgery arm had better overall survival than patients in the surgery arm (hazard ratio, 0.70; 95% confidence interval, 0.55-0.89; P = .004), with a 10-year overall survival of 38% (95% CI, 31-45) and 25% (95% CI, 19-32), respectively. No significant subgroup differences were observed for overall survival. Also, there was no evidence of a time-dependent effect of neoadjuvant chemoradiotherapy on overall survival. The major effect of neoadjuvant chemoradiotherapy, landmark analyses showed, was in the first 5 years of follow-up, with the effect on overall survival stabilized thereafter, with a hazard ratio approaching 1.00.
 

Cause-specific mortality

Eighty-four of 178 patients in the chemoradiotherapy-surgery arm died of esophageal cancer, with 32 dying of other causes. In the surgery arm, 121/188 died of esophageal cancer and 22 of other causes. The hazard ratio for esophageal cancer death in the chemoradiotherapy-surgery arm was 0.60 (95% CI, 0.46 to 0.80), with 10-year absolute risks of 47% (95% CI, 40-54) and 64% (95% CI,57-71), respectively, in the two arms. Death from other causes was comparable, with 10-year absolute risks of 15% (95% CI, 10-21) and 11% (95% CI, 7-16), respectively, for chemoradiotherapy-surgery versus surgery alone.

Locoregional relapse

Locoregional relapse rates were 8% (15/178) and 18% (33/188) in the chemoradiotherapy-surgery and surgery arms, respectively (HR, 0.39; 95% CI, 0.21-0.72). Eighty-seven percent of those developed within 3 years of follow-up in the chemoradiotherapy arm, with the median relapse-free interval at 3.9 months. In the surgery arm, 28 of 33 relapses (85%) developed within 3 years and the median relapse-free interval was 7.1 months. Beyond 6 years, there were no further relapses in either arm.

While synchronous distant plus locoregional relapse developed in 23 of 178 patients (13%) in the chemoradiotherapy-surgery arm and in 42 of 188 patients (22%) in the surgery arm (HR, 0.43; 95% CI, 0.26-0.72), isolated distant relapse developed at similar rates (around 27.5%) in both groups. Risk of distant relapse (with or without locoregional relapse) was lower in the chemoradiotherapy-surgery arm (HR, 0.61; 95%CI, 0.45-0.84). The median relapse-free interval was 15.1 months (interquartile range, 9.3-27.6) in the chemoradiotherapy-surgery arm and 9.0 months (IQR, 5.3-19.7) in the surgery arm.
 

Safety and health-related quality of life

The combination of paclitaxel and carboplatin with concurrent 41.4 Gy radiotherapy before surgery seems safe in the long term and does not significantly increase the risk of toxicity-related death, the researchers stated. Within the CROSS trial, short-term and long-term health-related quality of life after neoadjuvant chemoradiotherapy plus surgery for surviving patients was comparable to that after surgery alone.

Long-term persistent overall survival benefit

Ten-year CROSS results show that “for locally advanced resectable cancer of the esophagus or esophagogastric junction, preoperative chemoradiotherapy induces a long-term persistent improvement in overall survival.” Also, neoadjuvant chemoradiotherapy does not lead to an increased risk of death from other causes, and the survival benefit of long-term survivors is not compromised, compared with surgery alone. Furthermore, neoadjuvant chemoradiotherapy plus surgery according to CROSS can still be regarded as a standard of care, the researchers added.

Dr. Eyck and colleagues are currently performing the phase II TNT-OES-1 trial. It combines FLOT (fluorouracil, leucovorin, oxaliplatin and docetaxel) chemotherapy followed by CROSS chemoradiotherapy in patients with advanced esophageal and junctional adenocarcinoma. If this regimen appears to be safe in advanced cancer, they plan to perform a phase III trial with this regimen in locally advanced cancer. In addition, they are currently evaluating the implementation of adjuvant nivolumab in clinical practice for patients with pathologically residual disease after CROSS + surgery, based on the recently published CheckMate 577 trial .

“If possible, we prefer adding better systemic therapy to chemoradiotherapy rather than replacing chemoradiotherapy with systemic therapy alone,” Dr. Eyck said in an interview. “The reason for this is that we would like to allow patients with a complete response to neoadjuvant therapy to undergo active surveillance instead of surgery in the near future. … Since the pathologically complete response rate after regimens containing radiotherapy is substantially higher, we still prefer the addition of radiotherapy.”

The study was funded by the Dutch Cancer Foundation (KWF Kankerbestrijding). Dr. Eyck reported no disclosures. Several of the coauthors reported consulting and advisory roles with a variety of pharmaceutical companies.

Coronary artery vasospasm is a rare but well-known adverse effect of 5-fluorouracil (5-FU) that can be life threatening if unrecognized. Patients typically present with anginal chest pain and ST elevations on electrocardiogram (ECG) without atherosclerotic disease on coronary angiography. This phenomenon typically occurs during or shortly after infusion and resolves within hours to days after cessation of 5-FU.

In this report, we present an unusual case of coronary artery vasospasm that intermittently recurred for 25 days following 5-FU treatment in a 40-year-old male with stage IV gastric adenocarcinoma. We also review the literature on typical presentation and risk factors for 5-FU-induced coronary vasospasm, findings on coronary angiography, and management options.

5-FU is an IV administered antimetabolite chemotherapy commonly used to treat solid tumors, including gastrointestinal, pancreatic, breast, and head and neck tumors. 5-FU inhibits thymidylate synthase, which reduces levels of thymidine, a key pyrimidine nucleoside required for DNA replication within tumor cells.¹ For several decades, 5-FU has remained one of the first-line drugs for colorectal cancer because it may be curative. It is the third most commonly used chemotherapy in the world and is included on the World Health Organization’s list of essential medicines.²

Cardiotoxicity occurs in 1.2 to 18% of patients who receive 5-FU therapy.³ Although there is variability in presentation for acute cardiotoxicity from 5-FU, including sudden death, angina pectoris, myocardial infarction, and ventricular arrhythmias, the mechanism most commonly implicated is coronary artery vasospasm.³ The direct observation of active coronary artery vasospasm during left heart catheterization is rare due its transient nature; however, several case studies have managed to demonstrate this.^4,5 The pathophysiology of 5-FU-induced cardiotoxicity is unknown, but adverse effects on cardiac microvasculature, myocyte metabolism, platelet aggregation, and coronary vasoconstriction have all been proposed.^3,6In the current case, we present a patient with stage IV gastric adenocarcinoma who complained of chest pain during hospitalization and was found to have coronary artery vasospasm in the setting of recent 5-FU administration. Following coronary angiography that showed a lack of atherosclerotic disease, the patient continued to experience episodes of chest pain with ST elevations on ECG that recurred despite cessation of 5-FU and repeated administration of vasodilatory medications.

Case Presentation 

A male aged 40 years was admitted to the hospital for abdominal pain, with initial imaging concerning for partial small bowel obstruction. His history included recently diagnosed stage IV gastric adenocarcinoma complicated by peritoneal carcinomatosis status post initiation of infusional FOLFOX-4 (5-FU, leucovorin, and oxaliplatin) 11 days prior. The patient was treated for small bowel obstruction. However, several days after admission, he developed nonpleuritic, substernal chest pain unrelated to exertion and unrelieved by rest. The patient reported no known risk factors, family history, or personal history of coronary artery disease. Baseline echocardiography and ECG performed several months prior showed normal left ventricular function without ischemic findings.

Physical examination at the time of chest pain revealed a heart rate of 140 beats/min. The remainder of his vital signs were within normal range. There were no murmurs, rubs, gallops, or additional heart sounds heard on cardiac auscultation. Chest pain was not reproducible to palpation or positional in nature. An ECG demonstrated dynamic inferolateral ST elevations with reciprocal changes in leads I and aVL (Figure 1). A bedside echocardiogram showed hypokinesis of the septal wall. Troponin-I returned below the detectable level.

Treatment

Following catheterization, the patient returned to the medical intensive care unit, where he continued to report intermittent episodes of chest pain with ST elevations. In the following days, he was started on isosorbide mononitrate 150 mg daily and amlodipine 10 mg daily. Although these vasodilatory agents reduced the frequency of his chest pain episodes, intermittent chest pain associated with ST elevations on ECG continued even with maximal doses of isosorbide mononitrate and amlodipine. Administration of sublingual nitroglycerin during chest pain episodes effectively relieved his chest pain. Given the severity and frequency of the patient’s chest pain, the oncology consult team recommended foregoing further chemotherapeutic treatment with 5-FU.

Outcome

Despite holding 5-FU throughout the patient’s hospitalization and treating the patient with antianginal mediations, frequent chest pain episodes associated with ST elevations continued to recur until 25 days after his last treatment with 5-FU (Figure 4). The patient eventually expired during this hospital stay due to cancer-related complications.

Discussion

Coronary artery vasospasm is a well-known complication of 5-FU that can be life threatening if unrecognized.^6-8 As seen in our case, patients typically present with anginal chest pain relieved with nitrates and ST elevations on ECG in the absence of occlusive macrovascular disease on coronary angiography.

A unique aspect of 5-FU is its variability in dose and frequency of administration across chemotherapeutic regimens. Particularly, 5-FU can be administered in daily intravenous bolus doses or as a continuous infusion for a protracted length of time. The spectrum of toxicity from 5-FU differs depending on the dose and frequency of administration. Bolus administration of 5-FU, for example, is thought to be associated with a higher rate of myelosuppression, while infusional administration of 5-FU is thought to be associated with a higher rate of cardiotoxicity and a higher tumor response rate.⁹

Most cases of coronary vasospasm occur either during infusion of 5-FU or within hours to days after completion. The median time of presentation for 5-FU-induced coronary artery vasospasm is about 12 hours postinfusion, while the most delayed presentation reported in the literature is 72 hours postinfusion.^6,8 Delayed presentation of vasospasm may result from the release of potent vasoactive metabolites of 5-FU that accumulate over time; therefore, infusional administration may accentuate this effect.^6,9 Remarkably, our patient’s chest pain episodes persisted for 25 days despite treatment with anti-anginal medications, highlighting the extent to which infusional 5-FU can produce a delay in adverse cardiotoxic effects and the importance of ongoing clinical vigilance after 5-FU exposure.

Vasospasm alone does not completely explain the spectrum of cardiac toxicity attributed to 5-FU administration. As in our case, coronary angiography during symptomatic episodes often fails to demonstrate coronary vasospasm.⁸ Additionally, ergonovine, an alkaloid agent used to assess coronary vasomotor function, failed to induce coronary vasospasm in some patients with suspected 5-FU-induced cardiac toxicity.¹⁰ The lack of vasospasm in some patients with 5-FU-induced cardiac toxicity suggests multiple independent effects of 5-FU on cardiac tissue that are poorly understood.

In the absence of obvious macrovascular effects, there also may be a deleterious effect of 5-FU on the coronary microvasculature that may result in coronary artery vasospasm. Though coronary microvasculature cannot be directly visualized, observation of slowed coronary blood velocity indicates a reduction in microvascular flow.⁸ Thus, the failure to observe epicardial coronary vasospasm in our patient does not preclude a vasospastic pathology.

The heterogeneous presentation of coronary artery vasospasm demands consideration of other disease processes such as atherosclerotic coronary artery disease, pericarditis, myopericarditis, primary arrythmias, and stress-induced cardiomyopathy, all of which have been described in association with 5-FU administration.⁸ A 12-lead ECG should be performed during a suspected attack. An ECG will typically demonstrate ST elevations corresponding to spasm of the involved vessel. Reciprocal ST depressions in the contralateral leads also may be seen. ECG may be useful in the acute setting to identify regional wall motion abnormalities or to rule out pericardial effusion as a cause. Cardiac biomarkers such as troponin-I, -C, and creatine kinase typically are less useful because they are often normal, even in known coronary artery vasospasm.¹¹

Coronary angiography during an episode may show a localized region of vasospasm in an epicardial artery. Diffuse multivessel vasospasm does occur, and the location of vasospasm may change, but these events are rare. Under normal circumstances, provocative testing involving angiography with administration of acetylcholine, ergot agents, or hyperventilation can be performed. However, this type of investigation should be limited to specialized centers and should not be performed in the acute phase of the disease.¹²

Treatment of suspected coronary vasospasm in patients receiving 5-FU involves stopping the infusion and administering calcium channel blockers or oral nitrates to relieve anginal symptoms.¹³ 5-FU-induced coronary artery vasospasm has a 90% rate of recurrence with subsequent infusions.⁸ If possible, alternate chemotherapy regimens should be considered once coronary artery vasospasm has been identified.^14,15 If further 5-FU use is required, or if benefits are deemed to outweigh risks, infusions should be given in an inpatient setting with continuous cardiac monitoring.¹⁶

Calcium channel blockers and oral nitrates have been found to produce benefit in patients in acute settings; however, there is little evidence to attest to their effectiveness as prophylactic agents in those receiving 5-FU. Some reports demonstrate episodes where both calcium channel blockers and oral nitrates failed to prevent subsequent vasospasms.¹⁷ Although this was the case for our patient, short-acting sublingual nitroglycerin seemed to be effective in reducing the frequency of anginal symptoms.

Long-term outcomes have not been well investigated for patients with 5-FU-induced coronary vasospasm. However, many case reports show improvements in left ventricular function between 8 and 15 days after discontinuation of 5-FU.^7,10 Although this would be a valuable topic for further research, the rarity of this phenomenon creates limitations.

Conclusions

5-FU is a first-line chemotherapy for gastrointestinal cancers that is generally well tolerated but may be associated with potentially life-threatening cardiotoxic effects, of which coronary artery vasospasm is the most common. Coronary artery vasospasm presents with anginal chest pain and ST elevations on ECG that can be indistinguishable from acute coronary syndrome. Diagnosis requires cardiac catheterization, which will reveal patent coronary arteries. Infusional administration of 5-FU may be more likely to produce late cardiotoxic effects and a longer period of persistent symptoms, necessitating close monitoring for days or even weeks from last administration of 5-FU. Coronary artery vasospasm should be treated with anti-anginal medications, though varying degrees of effectiveness can be seen; clinicians should remain vigilant for recurrent episodes of chest pain despite treatment.

Coronary artery vasospasm is a rare but well-known adverse effect of 5-fluorouracil (5-FU) that can be life threatening if unrecognized. Patients typically present with anginal chest pain and ST elevations on electrocardiogram (ECG) without atherosclerotic disease on coronary angiography. This phenomenon typically occurs during or shortly after infusion and resolves within hours to days after cessation of 5-FU.

In this report, we present an unusual case of coronary artery vasospasm that intermittently recurred for 25 days following 5-FU treatment in a 40-year-old male with stage IV gastric adenocarcinoma. We also review the literature on typical presentation and risk factors for 5-FU-induced coronary vasospasm, findings on coronary angiography, and management options.

5-FU is an IV administered antimetabolite chemotherapy commonly used to treat solid tumors, including gastrointestinal, pancreatic, breast, and head and neck tumors. 5-FU inhibits thymidylate synthase, which reduces levels of thymidine, a key pyrimidine nucleoside required for DNA replication within tumor cells.¹ For several decades, 5-FU has remained one of the first-line drugs for colorectal cancer because it may be curative. It is the third most commonly used chemotherapy in the world and is included on the World Health Organization’s list of essential medicines.²

Cardiotoxicity occurs in 1.2 to 18% of patients who receive 5-FU therapy.³ Although there is variability in presentation for acute cardiotoxicity from 5-FU, including sudden death, angina pectoris, myocardial infarction, and ventricular arrhythmias, the mechanism most commonly implicated is coronary artery vasospasm.³ The direct observation of active coronary artery vasospasm during left heart catheterization is rare due its transient nature; however, several case studies have managed to demonstrate this.^4,5 The pathophysiology of 5-FU-induced cardiotoxicity is unknown, but adverse effects on cardiac microvasculature, myocyte metabolism, platelet aggregation, and coronary vasoconstriction have all been proposed.^3,6In the current case, we present a patient with stage IV gastric adenocarcinoma who complained of chest pain during hospitalization and was found to have coronary artery vasospasm in the setting of recent 5-FU administration. Following coronary angiography that showed a lack of atherosclerotic disease, the patient continued to experience episodes of chest pain with ST elevations on ECG that recurred despite cessation of 5-FU and repeated administration of vasodilatory medications.

Case Presentation 

A male aged 40 years was admitted to the hospital for abdominal pain, with initial imaging concerning for partial small bowel obstruction. His history included recently diagnosed stage IV gastric adenocarcinoma complicated by peritoneal carcinomatosis status post initiation of infusional FOLFOX-4 (5-FU, leucovorin, and oxaliplatin) 11 days prior. The patient was treated for small bowel obstruction. However, several days after admission, he developed nonpleuritic, substernal chest pain unrelated to exertion and unrelieved by rest. The patient reported no known risk factors, family history, or personal history of coronary artery disease. Baseline echocardiography and ECG performed several months prior showed normal left ventricular function without ischemic findings.

Physical examination at the time of chest pain revealed a heart rate of 140 beats/min. The remainder of his vital signs were within normal range. There were no murmurs, rubs, gallops, or additional heart sounds heard on cardiac auscultation. Chest pain was not reproducible to palpation or positional in nature. An ECG demonstrated dynamic inferolateral ST elevations with reciprocal changes in leads I and aVL (Figure 1). A bedside echocardiogram showed hypokinesis of the septal wall. Troponin-I returned below the detectable level.

Treatment

Following catheterization, the patient returned to the medical intensive care unit, where he continued to report intermittent episodes of chest pain with ST elevations. In the following days, he was started on isosorbide mononitrate 150 mg daily and amlodipine 10 mg daily. Although these vasodilatory agents reduced the frequency of his chest pain episodes, intermittent chest pain associated with ST elevations on ECG continued even with maximal doses of isosorbide mononitrate and amlodipine. Administration of sublingual nitroglycerin during chest pain episodes effectively relieved his chest pain.

Meralgia paresthetica (MP) is a sensory mononeuropathy of the lateral femoral cutaneous nerve (LFCN), clinically characterized by numbness, pain, and paresthesias involving the anterolateral aspect of the thigh. Estimates of MP incidence are derived largely from observational studies and reported to be about 3.2 to 4.3 cases per 10,000 patient-years.^1,2 Although typically arising during midlife and especially in the context of comorbid obesity, diabetes mellitus (DM), and excessive alcohol consumption, MP may occur at any age, and bears a slight predilection for males.^2-4

MP may be divided etiologically into iatrogenic and spontaneous subtypes.⁵ Iatrogenic cases generally are attributable to nerve injury in the setting of direct or indirect trauma (such as with patient malpositioning) arising in the context of multiple forms of procedural or surgical intervention (Table). Spontaneous MP is primarily thought to occur as a result of LFCN compression at the level of the inguinal ligament, wherein internal or external pressures may promote LFCN entrapment and resultant functional disruption (Figure 1).^6,7

Case Presentation

A male Vietnam War veteran aged 69 years presented to a primary care clinic at West Roxbury Veterans Affairs Medical Center (WRVAMC) in Massachusetts with progressive right lower extremity numbness. Three months prior to this visit, he was evaluated in an urgent care clinic at WRVAMC for 6 months of numbness and increasingly painful nocturnal paresthesias involving the same extremity. A targeted physical examination at that visit revealed an obese male wearing tight suspenders, as well as focally diminished sensation to light touch involving the anterolateral aspect of the thigh, extending from just below the right hip to above the knee. Sensation in the medial thigh was spared. Strength and reflexes were normal in the bilateral lower extremities. An abdominal examination was not performed. He received a diagnosis of MP and counseled regarding weight loss, glycemic control, garment optimization, and conservative analgesia with as-needed nonsteroidal anti-inflammatory drugs. He was instructed to follow-up closely with his primary care physician for further monitoring.

During the current visit, the patient reported 2 atraumatic falls the prior 2 months, attributed to escalating right leg weakness. The patient reported that ascending stairs had become difficult, and he was unable to cross his right leg over his left while in a seated position. The territory of numbness expanded to his front and inner thigh. Although previously he was able to hike 4 miles, he now was unable to walk more than half of a mile without developing shortness of breath. He reported frequent urination without hematuria and a recent weight gain of 8 pounds despite early satiety.

His medical history included hypertension, hypercholesterolemia, truncal obesity, noninsulin dependent DM, coronary artery disease, atrial flutter, transient ischemic attack, and benign positional paroxysmal vertigo. He was exposed to Agent Orange during his service in Vietnam. Family history was notable for breast cancer (mother), lung cancer (father), and an unspecified form of lymphoma (brother). He had smoked approximately 2 packs of cigarettes daily for 15 years but quit 38 years prior. He reported consuming on average 3 alcohol-containing drinks per week and no illicit drug use. He was adherent with all medications, including furosemide 40 mg daily, losartan 25 mg daily, metoprolol succinate 50 mg daily, atorvastatin 80 mg daily, metformin 500 mg twice daily, and rivaroxaban 20 mg daily with dinner.

His vital signs included a blood pressure of 123/58 mmHg, a pulse of 74 beats per minute, a respiratory rate of 16 breaths per minute, and an oxygen saturation of 94% on ambient air. His temperature was recorded at 96.7°F, and his weight was 234 pounds with a body mass index (BMI) of 34. He was well groomed and in no acute distress. His cardiopulmonary examination was normal. Carotid, radial, and bilateral dorsalis pedis pulsations were 2+ bilaterally, and no jugular venous distension was observed at 30°. The abdomen was protuberant. Nonshifting dullness to percussion and firmness to palpation was observed throughout right upper and lower quadrants, with hyperactive bowel sounds primarily localized to the left upper and lower quadrants.

Neurologic examination revealed symmetric facies with normal phonation and diction. He was spontaneously moving all extremities, and his gait was normal. Sensation to light touch was severely diminished throughout the anterolateral and medial thigh, extending to the level of the knee, and otherwise reduced in a stocking-type pattern over the bilateral feet and toes. His right hip flexion, adduction, as well as internal and external rotation were focally diminished to 4- out of 5. Right knee extension was 4+ out of 5. Strength was otherwise 5 out of 5. The patient exhibited asymmetric Patellar reflexes—absent on the right and 2+ on the left. Achilles reflexes were absent bilaterally. Straight-leg raise test was negative bilaterally and did not clearly exacerbate his right leg numbness or paresthesias. There were no notable fasciculations. There was 2+ bilateral lower extremity pitting edema appreciated to the level of the midshin (right greater than left), without palpable cords or new skin lesions.

Upon referral to the neurology service, the patient underwent electromyography, which revealed complex repetitive discharges in the right tibialis anterior and pattern of reduced recruitment upon activation of the right vastus medialis, collectively suggestive of an L3-4 plexopathy. The patient was admitted for expedited workup.

A complete blood count and metabolic panel that were taken in the emergency department were normal, save for a serum bicarbonate of 30 mEq/L. His hemoglobin A_1c was 6.6%. Computed tomography (CT) of the abdomen and pelvis with IV contrast was obtained, and notable for a 30 cm fat-containing right-sided retroperitoneal mass with associated solid nodular components and calcification (Figure 2). No enhancement of the lesion was observed. There was significant associated mass effect, with superior displacement of the liver and right hemidiaphragm, as well as superomedial deflection of the right kidney, inferior vena cava, and other intraabdominal organs. Subsequent imaging with a CT of the chest, as well as magnetic resonance imaging of the brain, were without evidence of metastatic disease.

Outcome

The patient was treated with external beam radiotherapy (EBRT) delivered simultaneously to both the prostate and high-risk retroperitoneal margins of the DDLPS, as well as concurrent androgen deprivation therapy. Five months after completed radiotherapy, resection of the DDLPS was attempted. However, palliative tumor debulking was instead performed due to extensive locoregional invasion with involvement of the posterior peritoneum and ipsilateral quadratus, iliopsoas, and psoas muscles, as well as the adjacent lumbar nerve roots.

At present, the patient is undergoing surveillance imaging every 3 months to reevaluate his underlying disease burden, which has thus far been radiographically stable. Current management at the primary care level is focused on preserving quality of life, particularly maintaining mobility and functional independence.

Discussion

Although generally a benign entrapment neuropathy, MP bears well-established associations with multiple forms of must-not-miss pathology. Here, we present the case of a veteran in whom MP was the index presentation of a massive retroperitoneal liposarcoma, stressing the importance of a thorough history and physical examination in all patients presenting with MP. The case presented herein highlights many of the red-flag signs and symptoms that primary care physicians might encounter in patients with retroperitoneal pathology, including MP and MP-like syndromes (Figure 4).

In this case, the pretest probability of a spontaneous and uncomplicated MP was high given the patient’s sex, age, body habitus, and DM; however, there important atypia that emerged as the case evolved, including: (1) the progressive course; (2) proximal right lower extremity weakness; (3) asymmetric patellar reflexes; and (4) numerous clinical stigmata of intraabdominal mass effect. The patient exhibited abnormalities on abdominal examination that suggested the presence of an underlying intraabdominal mass, providing key diagnostic insight into this case. Given the slowly progressive nature of liposarcomas, we feel the abnormalities appreciated on abdominal examination were likely apparent during the initial presentation.¹⁸

There are numerous cognitive biases that may explain why an abdominal examination was not prioritized during the initial presentation. Namely, the patient’s numerous risk factors for spontaneous MP, as detailed above, may have contributed to framing bias that limited consideration of alternative diagnoses. In addition, the patient’s physical examination likely contributed to search satisfaction, whereby alternative diagnoses were not further entertained after discovery of findings consistent with spontaneous MP.¹⁹ Finally, it remains conceivable that an abdominal examination was not prioritized as it is often perceived as being distinct from, rather than an integral part of, the neurologic examination.²⁰ Given that numerous neurologic disorders may present with abdominal pathology, we feel a thorough abdominal examination should be considered part of the full neurologic examination, especially in cases presenting with focal neurologic findings involving the lower extremities.²¹

Collectively, this case alludes to the importance of close clinical follow-up, as well as adequate anticipatory patient guidance in cases of suspected MP. In most patients, the clinical course of spontaneous MP is benign and favorable, with up to 85% of patients experiencing resolution within 4 to 6 months of the initial presentation.²² Common conservative measures include weight loss, garment optimization, and nonsteroidal anti-inflammatory drugs as needed for analgesia. In refractory cases, procedural interventions such as with neurolysis or resection of the lateral femoral cutaneous nerve, may be required after the ruling out of alternative diagnoses.^23,24

Importantly, in even prolonged and resistant cases of MP, patient discomfort remains localized to the territory of the LFCN. Additional lower motor neuron signs, such as an expanding territory of sensory involvement, muscle weakness, or diminished reflexes, should prompt additional testing for alternative diagnoses. In addition, clinical findings concerning for intraabdominal mass effect, many of which were observed in this case, should lead to further evaluation and expeditious cross-sectional imaging. Although this patient’s early satiety, polyuria, bilateral lower extremity edema, weight gain, and lumbar plexopathy each may be explained by direct compression, invasion, or displacement, his report of progressive exertional dyspnea merits further discussion.

Exertional dyspnea is an uncommon complication of soft tissue sarcoma, reported almost exclusively in cases with cardiac, mediastinal, or other thoracic involvement.^25-28 In this case, there was no evidence of thoracic involvement, either through direct extension or metastasis. Instead, the patient’s exertional dyspnea may have been attributable to increased intraabdominal pressure leading to compromised diaphragm excursion and reduced pulmonary reserve. In addition, the radiographic findings also raise the possibility of a potential contribution from preload failure due to IVC compression. Overall, dyspnea is a concerning feature that may suggest advanced disease.

Despite the value of a thorough history and physical examination in patients with MP, major clinical guidelines from neurologic, neurosurgical, and orthopedic organizations do not formally address MP evaluation and management. Further, proposed clinical practice algorithms are inconsistent in their recommendations regarding the identification of red-flag features and ruling out of alternative diagnoses.^22,29,30 To supplement the abdominal examination, it would be reasonable to perform a pelvic compression test (PCT) in patients presenting with suspected MP. The PCT is a highly sensitive and specific provocative maneuver shown to enable reliable differentiation between MP and lumbar radiculopathy, and is performed by placing downward force on the anterior superior iliac spine of the affected extremity for 45 seconds with the patient in the lateral recumbent position.³¹ As this maneuver is intended to force relaxation of the inguinal ligament, thereby relieving pressure on the LFCN, improvement in the patient’s symptoms with the PCT is consistent with MP.

Conclusions

Spontaneous MP is a generally benign condition secondary to LFCN entrapment at the level of the inguinal ligament and is encountered frequently in the context of comorbid obesity and DM. However, MP bears known associations with high-risk pathologies that engender specific diagnostic and therapeutic considerations, including retroperitoneal mass lesions. The case presented herein highlights the utility of: (1) a focused history and review of systems to aid in the identification of red-flag symptoms and signs that might suggest a secondary etiology; and (2) a thorough abdominal examination in all patients who present with MP, especially in atypical presentations, cases with additional focal neurologic findings, or in patients who report progressive symptoms. Given the progressively aging population within the United States, coupled with an expanding prevalence of obesity and diabetes mellitus, recognition of the typical and atypical features of MP may be of progressive importance.

Meralgia paresthetica (MP) is a sensory mononeuropathy of the lateral femoral cutaneous nerve (LFCN), clinically characterized by numbness, pain, and paresthesias involving the anterolateral aspect of the thigh. Estimates of MP incidence are derived largely from observational studies and reported to be about 3.2 to 4.3 cases per 10,000 patient-years.^1,2 Although typically arising during midlife and especially in the context of comorbid obesity, diabetes mellitus (DM), and excessive alcohol consumption, MP may occur at any age, and bears a slight predilection for males.^2-4

MP may be divided etiologically into iatrogenic and spontaneous subtypes.⁵ Iatrogenic cases generally are attributable to nerve injury in the setting of direct or indirect trauma (such as with patient malpositioning) arising in the context of multiple forms of procedural or surgical intervention (Table). Spontaneous MP is primarily thought to occur as a result of LFCN compression at the level of the inguinal ligament, wherein internal or external pressures may promote LFCN entrapment and resultant functional disruption (Figure 1).^6,7

Case Presentation

A male Vietnam War veteran aged 69 years presented to a primary care clinic at West Roxbury Veterans Affairs Medical Center (WRVAMC) in Massachusetts with progressive right lower extremity numbness. Three months prior to this visit, he was evaluated in an urgent care clinic at WRVAMC for 6 months of numbness and increasingly painful nocturnal paresthesias involving the same extremity. A targeted physical examination at that visit revealed an obese male wearing tight suspenders, as well as focally diminished sensation to light touch involving the anterolateral aspect of the thigh, extending from just below the right hip to above the knee. Sensation in the medial thigh was spared. Strength and reflexes were normal in the bilateral lower extremities. An abdominal examination was not performed. He received a diagnosis of MP and counseled regarding weight loss, glycemic control, garment optimization, and conservative analgesia with as-needed nonsteroidal anti-inflammatory drugs. He was instructed to follow-up closely with his primary care physician for further monitoring.

During the current visit, the patient reported 2 atraumatic falls the prior 2 months, attributed to escalating right leg weakness. The patient reported that ascending stairs had become difficult, and he was unable to cross his right leg over his left while in a seated position. The territory of numbness expanded to his front and inner thigh. Although previously he was able to hike 4 miles, he now was unable to walk more than half of a mile without developing shortness of breath. He reported frequent urination without hematuria and a recent weight gain of 8 pounds despite early satiety.

His medical history included hypertension, hypercholesterolemia, truncal obesity, noninsulin dependent DM, coronary artery disease, atrial flutter, transient ischemic attack, and benign positional paroxysmal vertigo. He was exposed to Agent Orange during his service in Vietnam. Family history was notable for breast cancer (mother), lung cancer (father), and an unspecified form of lymphoma (brother). He had smoked approximately 2 packs of cigarettes daily for 15 years but quit 38 years prior. He reported consuming on average 3 alcohol-containing drinks per week and no illicit drug use. He was adherent with all medications, including furosemide 40 mg daily, losartan 25 mg daily, metoprolol succinate 50 mg daily, atorvastatin 80 mg daily, metformin 500 mg twice daily, and rivaroxaban 20 mg daily with dinner.

His vital signs included a blood pressure of 123/58 mmHg, a pulse of 74 beats per minute, a respiratory rate of 16 breaths per minute, and an oxygen saturation of 94% on ambient air. His temperature was recorded at 96.7°F, and his weight was 234 pounds with a body mass index (BMI) of 34. He was well groomed and in no acute distress. His cardiopulmonary examination was normal. Carotid, radial, and bilateral dorsalis pedis pulsations were 2+ bilaterally, and no jugular venous distension was observed at 30°. The abdomen was protuberant. Nonshifting dullness to percussion and firmness to palpation was observed throughout right upper and lower quadrants, with hyperactive bowel sounds primarily localized to the left upper and lower quadrants.

Neurologic examination revealed symmetric facies with normal phonation and diction. He was spontaneously moving all extremities, and his gait was normal. Sensation to light touch was severely diminished throughout the anterolateral and medial thigh, extending to the level of the knee, and otherwise reduced in a stocking-type pattern over the bilateral feet and toes. His right hip flexion, adduction, as well as internal and external rotation were focally diminished to 4- out of 5. Right knee extension was 4+ out of 5. Strength was otherwise 5 out of 5. The patient exhibited asymmetric Patellar reflexes—absent on the right and 2+ on the left. Achilles reflexes were absent bilaterally. Straight-leg raise test was negative bilaterally and did not clearly exacerbate his right leg numbness or paresthesias. There were no notable fasciculations. There was 2+ bilateral lower extremity pitting edema appreciated to the level of the midshin (right greater than left), without palpable cords or new skin lesions.

Upon referral to the neurology service, the patient underwent electromyography, which revealed complex repetitive discharges in the right tibialis anterior and pattern of reduced recruitment upon activation of the right vastus medialis, collectively suggestive of an L3-4 plexopathy. The patient was admitted for expedited workup.

A complete blood count and metabolic panel that were taken in the emergency department were normal, save for a serum bicarbonate of 30 mEq/L. His hemoglobin A_1c was 6.6%. Computed tomography (CT) of the abdomen and pelvis with IV contrast was obtained, and notable for a 30 cm fat-containing right-sided retroperitoneal mass with associated solid nodular components and calcification (Figure 2). No enhancement of the lesion was observed. There was significant associated mass effect, with superior displacement of the liver and right hemidiaphragm, as well as superomedial deflection of the right kidney, inferior vena cava, and other intraabdominal organs. Subsequent imaging with a CT of the chest, as well as magnetic resonance imaging of the brain, were without evidence of metastatic disease.

Outcome

The patient was treated with external beam radiotherapy (EBRT) delivered simultaneously to both the prostate and high-risk retroperitoneal margins of the DDLPS, as well as concurrent androgen deprivation therapy. Five months after completed radiotherapy, resection of the DDLPS was attempted. However, palliative tumor debulking was instead performed due to extensive locoregional invasion with involvement of the posterior peritoneum and ipsilateral quadratus, iliopsoas, and psoas muscles, as well as the adjacent lumbar nerve roots.

At present, the patient is undergoing surveillance imaging every 3 months to reevaluate his underlying disease burden, which has thus far been radiographically stable. Current management at the primary care level is focused on preserving quality of life, particularly maintaining mobility and functional independence.

Discussion

Although generally a benign entrapment neuropathy, MP bears well-established associations with multiple forms of must-not-miss pathology. Here, we present the case of a veteran in whom MP was the index presentation of a massive retroperitoneal liposarcoma, stressing the importance of a thorough history and physical examination in all patients presenting with MP. The case presented herein highlights many of the red-flag signs and symptoms that primary care physicians might encounter in patients with retroperitoneal pathology, including MP and MP-like syndromes (Figure 4).

Hematology and oncology patients are a complex patient population that requires timely follow-up to prevent clinical decompensation and delays in treatment. Previous reports have demonstrated that outpatient follow-up within 14 days is associated with decreased 30-day readmissions. The magnitude of this effect is greater for higher-risk patients.¹ Therefore, patients being discharged from the hematology and oncology inpatient service should be seen by a hematology and oncology provider within 14 days of discharge. Patients who do not require close oncologic follow-up should be seen by a primary care provider (PCP) within this timeframe.

Background

The Institute of Medicine (IOM) identified the need to focus on quality improvement and patient safety with a 1999 report, To Err Is Human.² Tremendous strides have been made in the areas of quality improvement and patient safety over the past 2 decades. In a 2013 report, the IOM further identified hematology and oncology care as an area of need due to a combination of growing demand, complexity of cancer and cancer treatment, shrinking workforce, and rising costs. The report concluded that cancer care is not as patient-centered, accessible, coordinated, or evidence based as it could be, with detrimental impacts on patients.³ Patients with cancer have been identified as a high-risk population for hospital readmissions.^4,5 Lack of timely follow-up and failed hand-offs have been identified as factors contributing to poor outcomes at time of discharge.^6-10

Upon internal review of baseline performance data, we identified areas needing improvement in the discharge process. These included time to hematology and oncology follow-up appointment, percent of patients with PCP appointments scheduled at time of discharge, and electronically alerts for the outpatient hematologist/oncologist to discharge summaries. It was determined that patients discharged from the inpatient service were seen a mean 17 days later by their outpatient hematology and oncology provider and the time to the follow-up appointment varied substantially, with some patients being seen several weeks to months after discharge. Furthermore, only 68% of patients had a primary care appointment scheduled at the time of discharge. These data along with review of data reported in the medical literature supported our initiative for improvement in the transition from inpatient to outpatient care for our hematology and oncology patients.

Plan-Do-Study-Act (PDSA) quality improvement methodology was used to create and implement several interventions to standardize the discharge process for this patient population, with the primary goal of decreasing the mean time to hematology and oncology follow-up from 17 days by 12% to fewer than 14 days. Patients who do not require close oncologic follow-up should be seen by a PCP within this timeframe. Otherwise, PCP follow-up within at least 6 months should be made. Secondary aims included (1) an increase in scheduled PCP visits at time of discharge from 68% to > 90%; and (2) an increase in communication of the discharge summary via electronic alerting of the outpatient hematology and oncology physician from 20% to > 90%. Herein, we report our experience and results of this quality improvement initiative

Methods

The Institutional Review Board at Edward Hines Veteran Affairs Hospital in Hines, Illinois reviewed this single-center study and deemed it to be exempt from oversight. Using PDSA quality improvement methodology, a multidisciplinary team of hematology and oncology staff developed and implemented a standardized discharge process. The multidisciplinary team included a robust representation of inpatient and outpatient staff caring for the hematology and oncology patient population, including attending physicians, fellows, residents, advanced practice nurses, registered nurses, clinical pharmacists, patient care coordinators, clinic schedulers, clinical applications coordinators, quality support staff, and a systems redesign coach. Hospital leadership including chief of staff, chief of medicine, and chief of nursing participated as the management guidance team. Several interviews and group meetings were conducted and a multidisciplinary team collaboratively developed and implemented the interventions and monitored the results.

Outcome measures were identified, including time to hematology and oncology clinic visit, primary care follow-up scheduling, and communication of discharge to the outpatient hematology and oncology physician. Baseline data were collected and reviewed. The multidisciplinary team developed a process flow map to understand the steps and resources involved with the transition from inpatient to outpatient care. Gap analysis and root cause analysis were performed. A solutions approach was applied to develop interventions. Table 1 shows a summary of the identified problems, symptoms, associated causes, the interventions aimed to address the problems, and expected outcomes. Rotating resident physicians were trained through online and in-person education. The multidisciplinary team met intermittently to monitor outcomes, provide feedback, further refine interventions, and develop additional interventions.

PDSA Cycle 1

A standardized discharge process was developed in the form of guidelines and expectations. These include an explanation of unique features of the hematology and oncology service and expectations of medication reconciliation with emphasis placed on antiemetics, antimicrobial prophylaxis, and bowel regimen when appropriate, outpatient hematology and oncology follow-up within 14 days, primary care follow-up, communication with the outpatient hematology and oncology physician, written discharge instructions, and bedside teaching when appropriate.

PDSA Cycle 2

Based on team member feedback and further discussions, a discharge checklist was developed. This checklist was available online, reviewed in person, and posted in the team room for rotating residents to use for discharge planning and when discharging patients (Figure 1).

PDSA Cycle 3

Based on ongoing user feedback, group discussions, and data monitoring, the discharge checklist was further refined and updated. An electronic clinical decision support tool was developed and integrated into the electronic medical record (EMR) in the form of a discharge checklist note template directly linked to orders. The tool is a computerized patient record system (CPRS) note template that prompts users to select whether medications or return to clinic orders are needed and offers a menu of frequently used medications. If any of the selections are chosen within the note template, an order is generated automatically in the chart that requires only the user’s signature. Furthermore, the patient care coordinator reviews the prescribed follow-up and works with the medical support assistant to make these appointments. The physician is contacted only when an appointment cannot be made. Therefore, this tool allows many additional actions to be bypassed such as generating medication and return to clinic orders individually and calling schedulers to make follow-up appointments (Figure 2).

Data Analysis

All patients discharged during the 2-month period prior to and discharged after the implementation of the standardized process were reviewed. Patients who followed up with hematology and oncology at another facility, enrolled in hospice, or died during admission were excluded. Follow-up appointment scheduling data and communication between inpatient and outpatient providers were reviewed. Data were analyzed using XmR statistical process control chart and Fisher’s Exact Test using GraphPad. Control limits were calculated for each PDSA cycle as the mean ± the average of the moving range multiplied by 2.66. All data were included in the analysis.

Results

A total of 142 consecutive patients were reviewed from May 1, 2018 to August 31, 2018 and January 1, 2019 to April 30, 2019, including 58 patients prior to the intervention and 84 patients during PDSA cycles. There was a gap in data collection between September 1, 2018 and December 31, 2018 due to limited team member availability. All data were collected by 2 reviewers—a postgraduate year (PGY)-4 chief resident and a PGY-2 internal medicine resident. The median age of patients in the preintervention group was 72 years and 69 years in the postintervention group. All patients were men. Baseline data revealed a mean 17 days to hematology and oncology follow-up. Primary care visits were scheduled for 68% of patients at the time of discharge. The outpatient hematology and oncology physician was alerted electronically to the discharge summary for 20% of the patients (Table 2).

The primary endpoint of time to hematology and oncology follow-up appointment improved to 13 days in PDSA cycles 1 and 2 and 10 days in PDSA cycle 3. The target of mean 14 days to follow-up was achieved. The statistical process control chart shows 5 shifts with clusters of ≥ 7 points below the mean revealing a true signal or change in the data and demonstrating that an improvement was seen (Figure 3). Furthermore, the statistical process control chart demonstrates upper control limit decreased from 58 days at baseline to 21 days in PDSA cycle 3, suggesting a decrease in variation.

Discussion

The 2013 IOM report Delivering High-Quality Cancer Care: Charting a New Course for a System in Crisis found that that cancer care is not as patient-centered, accessible, coordinated, or evidence-based as it could be, with detrimental impacts on patients.³ The document offered a conceptual framework to improve quality of cancer care that includes the translation of evidence into clinical practice, quality measurement, and performance improvement, as well as using advances in information technology to enhance quality measurement and performance improvement. Our quality initiative uses this framework to work toward the goal as stated by the IOM report: to deliver “comprehensive, patient-centered, evidence-based, high-quality cancer care that is accessible and affordable.”³

Two large studies that evaluated risk factors for 15-day and 30-day hospital readmissions identified cancer diagnosis as a risk factor for increased hospital readmission, highlighting the need to identify strategies to improve the discharge process for these patients.^4,5 Timely outpatient follow-up and better patient hand-off may improve clinical outcomes among this high-risk patient population after hospital discharge. Multiple studies have demonstrated that timely follow-up is associated with fewer readmissions.^1,8-10 A study by Forster and colleagues that evaluated postdischarge adverse events (AEs) revealed a 23% incidence of AEs with 12% of these identified as preventable. Postdischarge monitoring was deemed inadequate among these patients, with closer follow-up and improved hand-offs between inpatient and outpatient medical teams identified as possible interventions to improve postdischarge patient monitoring and to prevent AEs.⁷

The present quality initiative to standardize the discharge process for the hematology and oncology service decreased time to hematology and oncology follow-up appointment, improved communication between inpatient and outpatient teams, and decreased process variation. Timelier follow-up for this complex patient population likely will prevent clinical decompensation, delays in treatment, and directly improve patient access to care.

The multidisciplinary nature of this effort was instrumental to successful completion. In a complex health care system, it is challenging to truly understand a problem and identify possible solutions without the perspective of all members of the care team. The involvement of team members with training in quality improvement methodology was important to evaluate and develop interventions in a systematic way. Furthermore, the support and involvement of leadership is important in order to allocate resources appropriately to achieve system changes that improve care. Using quality improvement methodology, the team was able to map our processes and perform gap and root cause analyses. Strategies were identified to improve our performance using a solutions approach. Changes were implemented with continued intermittent meetings for monitoring of progression and discussion of how interventions could be made more efficient, effective, and user friendly. The primary goal was ultimately achieved.

Integration of intervention into the EMR embodies the IOM’s call to use advances in information technology to enhance the quality and delivery of care, quality measurement, and performance improvement.³ This intervention offered the strongest system changes as an electronic clinical decision support tool was developed and embedded into the EMR in the form of a Discharge Checklist Note that is linked to associated orders. This intervention was the most robust, as it provided objective data regarding utilization of the checklist, offered a more efficient way to communicate with team members regarding discharge needs, and streamlined the workflow for the discharging provider. Furthermore, this electronic tool created the ability to measure other important aspects in the care of this patient population that we previously had no mechanism of measuring: timely nursing appointments for routine care of PICC lines and ports.

Limitations

The absence of clinical endpoints was a limitation of this study. The present study was unable to evaluate the effect of the intervention on readmission rates, emergency department visits, hospital length of stay, cost, or mortality. Coordinating this multidisciplinary effort required much time and planning, and additional resources were not available to evaluate these clinical endpoints. Further studies are needed to evaluate whether the increased patient access and closer follow-up would result in improvement in these clinical endpoints. Another consideration for future improvement projects would be to include patients in the multidisciplinary team. The patient perspective would be invaluable in identifying gaps in care delivery and strategies aimed at improving care delivery.

Conclusions

This quality initiative to standardize the discharge process for the hematology and oncology service decreased time to the initial hematology and oncology follow-up appointment, improved communication between inpatient and outpatient teams, and decreased process variation. Timelier follow-up for this complex patient population likely will prevent clinical decompensation, delays in treatment, and directly improve patient access to care.

Hematology and oncology patients are a complex patient population that requires timely follow-up to prevent clinical decompensation and delays in treatment. Previous reports have demonstrated that outpatient follow-up within 14 days is associated with decreased 30-day readmissions. The magnitude of this effect is greater for higher-risk patients.¹ Therefore, patients being discharged from the hematology and oncology inpatient service should be seen by a hematology and oncology provider within 14 days of discharge. Patients who do not require close oncologic follow-up should be seen by a primary care provider (PCP) within this timeframe.

Background

The Institute of Medicine (IOM) identified the need to focus on quality improvement and patient safety with a 1999 report, To Err Is Human.² Tremendous strides have been made in the areas of quality improvement and patient safety over the past 2 decades. In a 2013 report, the IOM further identified hematology and oncology care as an area of need due to a combination of growing demand, complexity of cancer and cancer treatment, shrinking workforce, and rising costs. The report concluded that cancer care is not as patient-centered, accessible, coordinated, or evidence based as it could be, with detrimental impacts on patients.³ Patients with cancer have been identified as a high-risk population for hospital readmissions.^4,5 Lack of timely follow-up and failed hand-offs have been identified as factors contributing to poor outcomes at time of discharge.^6-10

Upon internal review of baseline performance data, we identified areas needing improvement in the discharge process. These included time to hematology and oncology follow-up appointment, percent of patients with PCP appointments scheduled at time of discharge, and electronically alerts for the outpatient hematologist/oncologist to discharge summaries. It was determined that patients discharged from the inpatient service were seen a mean 17 days later by their outpatient hematology and oncology provider and the time to the follow-up appointment varied substantially, with some patients being seen several weeks to months after discharge. Furthermore, only 68% of patients had a primary care appointment scheduled at the time of discharge. These data along with review of data reported in the medical literature supported our initiative for improvement in the transition from inpatient to outpatient care for our hematology and oncology patients.

Plan-Do-Study-Act (PDSA) quality improvement methodology was used to create and implement several interventions to standardize the discharge process for this patient population, with the primary goal of decreasing the mean time to hematology and oncology follow-up from 17 days by 12% to fewer than 14 days. Patients who do not require close oncologic follow-up should be seen by a PCP within this timeframe. Otherwise, PCP follow-up within at least 6 months should be made. Secondary aims included (1) an increase in scheduled PCP visits at time of discharge from 68% to > 90%; and (2) an increase in communication of the discharge summary via electronic alerting of the outpatient hematology and oncology physician from 20% to > 90%. Herein, we report our experience and results of this quality improvement initiative

Methods

The Institutional Review Board at Edward Hines Veteran Affairs Hospital in Hines, Illinois reviewed this single-center study and deemed it to be exempt from oversight. Using PDSA quality improvement methodology, a multidisciplinary team of hematology and oncology staff developed and implemented a standardized discharge process. The multidisciplinary team included a robust representation of inpatient and outpatient staff caring for the hematology and oncology patient population, including attending physicians, fellows, residents, advanced practice nurses, registered nurses, clinical pharmacists, patient care coordinators, clinic schedulers, clinical applications coordinators, quality support staff, and a systems redesign coach. Hospital leadership including chief of staff, chief of medicine, and chief of nursing participated as the management guidance team. Several interviews and group meetings were conducted and a multidisciplinary team collaboratively developed and implemented the interventions and monitored the results.

Outcome measures were identified, including time to hematology and oncology clinic visit, primary care follow-up scheduling, and communication of discharge to the outpatient hematology and oncology physician. Baseline data were collected and reviewed. The multidisciplinary team developed a process flow map to understand the steps and resources involved with the transition from inpatient to outpatient care. Gap analysis and root cause analysis were performed. A solutions approach was applied to develop interventions. Table 1 shows a summary of the identified problems, symptoms, associated causes, the interventions aimed to address the problems, and expected outcomes. Rotating resident physicians were trained through online and in-person education. The multidisciplinary team met intermittently to monitor outcomes, provide feedback, further refine interventions, and develop additional interventions.

PDSA Cycle 1

A standardized discharge process was developed in the form of guidelines and expectations. These include an explanation of unique features of the hematology and oncology service and expectations of medication reconciliation with emphasis placed on antiemetics, antimicrobial prophylaxis, and bowel regimen when appropriate, outpatient hematology and oncology follow-up within 14 days, primary care follow-up, communication with the outpatient hematology and oncology physician, written discharge instructions, and bedside teaching when appropriate.

PDSA Cycle 2

Based on team member feedback and further discussions, a discharge checklist was developed. This checklist was available online, reviewed in person, and posted in the team room for rotating residents to use for discharge planning and when discharging patients (Figure 1).

PDSA Cycle 3

Based on ongoing user feedback, group discussions, and data monitoring, the discharge checklist was further refined and updated. An electronic clinical decision support tool was developed and integrated into the electronic medical record (EMR) in the form of a discharge checklist note template directly linked to orders. The tool is a computerized patient record system (CPRS) note template that prompts users to select whether medications or return to clinic orders are needed and offers a menu of frequently used medications. If any of the selections are chosen within the note template, an order is generated automatically in the chart that requires only the user’s signature. Furthermore, the patient care coordinator reviews the prescribed follow-up and works with the medical support assistant to make these appointments. The physician is contacted only when an appointment cannot be made. Therefore, this tool allows many additional actions to be bypassed such as generating medication and return to clinic orders individually and calling schedulers to make follow-up appointments (Figure 2).

Data Analysis

All patients discharged during the 2-month period prior to and discharged after the implementation of the standardized process were reviewed. Patients who followed up with hematology and oncology at another facility, enrolled in hospice, or died during admission were excluded. Follow-up appointment scheduling data and communication between inpatient and outpatient providers were reviewed. Data were analyzed using XmR statistical process control chart and Fisher’s Exact Test using GraphPad. Control limits were calculated for each PDSA cycle as the mean ± the average of the moving range multiplied by 2.66. All data were included in the analysis.

Stereotactic ablative radiotherapy (SABR) has become the standard of care for inoperable early-stage non-small cell lung cancer (NSCLC). Many patients are unable to undergo a biopsy safely because of poor pulmonary function or underlying emphysema and are then empirically treated with radiotherapy if they meet criteria. In these patients, local control can be achieved with SABR with minimal toxicity.¹ Considering that median overall survival (OS) among patients with untreated stage I NSCLC has been reported to be as low as 9 months, early treatment with SABR could lead to increased survival of 29 to 60 months.^2-4

The RTOG 0236 trial showed a median OS of 48 months and the randomized phase III CHISEL trial showed a median OS of 60 months; however, these survival data were reported in patients who were able to safely undergo a biopsy and had confirmed NSCLC.^4,5 For patients without a diagnosis confirmed by biopsy and who are treated with empiric SABR, patient factors that influence radiation toxicity and OS are not well defined.

It is not clear if empiric radiation benefits survival or if treatment causes decline in lung function, considering that underlying chronic lung disease precludes these patients from biopsy. The purpose of this study was to evaluate the factors associated with radiation toxicity with empiric SABR and to evaluate OS in this population without a biopsy-confirmed diagnosis.

Methods

This was a single center retrospective review of patients treated at the radiation oncology department at the Kansas City Veterans Affairs Medical Center from August 2014 to February 2019. Data were collected on 69 patients with pulmonary nodules identified by chest computed tomography (CT) and/or positron emission tomography (PET)-CT that were highly suspicious for primary NSCLC.

These patients were presented at a multidisciplinary meeting that involved pulmonologists, oncologists, radiation oncologists, and thoracic surgeons. Patients were deemed to be poor candidates for biopsy because of severe underlying emphysema, which would put them at high risk for pneumothorax with a percutaneous needle biopsy, or were unable to tolerate general anesthesia for navigational bronchoscopy or surgical biopsy because of poor lung function. These patients were diagnosed with presumed stage I NSCLC using the criteria: minimum of 2 sequential CT scans with enlarging nodule; absence of metastases on PET-CT; the single nodule had to be fluorodeoxyglucose avid with a minimum standardized uptake value of 2.5, and absence of clinical history or physical examination consistent with small cell lung cancer or infection.

After a consensus was reached that patients met these criteria, individuals were referred for empiric SABR. Follow-up visits were at 1 month, 3 months, and every 6 months. Variables analyzed included: patient demographics, pre- and posttreatment pulmonary function tests (PFT) when available, pre-treatment oxygen use, tumor size and location (peripheral, central, or ultra-central), radiation doses, and grade of toxicity as defined by Human and Health Services Common Terminology Criteria for Adverse Events version 5.0 (dyspnea and cough both counted as pulmonary toxicity): acute ≤ 90 days and late > 90 days (Table 1).

Results

The median follow-up was 18 months (range, 1 to 54). The median age was 71 years (range, 59 to 95) (Table 2). Most patients (97.1%) were male. The majority of patients (79.4%) had a 0 or 1 for the Eastern Cooperative Oncology group performance status, indicating fully active or restricted in physically strenuous activity but ambulatory and able to perform light work. All patients were either current or former smokers with an average pack-year history of 69.4. Only 11.6% of patients had operable disease, but received empiric SABR because they declined surgery. Four patients did not have pretreatment spirometry available and 37 did not have pretreatment diffusing capacity for carbon monoxide (DLCO) data.

Most patients had a pretreatment forced expiratory volume during the first seconds (FEV₁) value and DLCO < 60% of predicted (60% and 84% of the patients, respectively). The median tumor diameter was 2 cm. Of the 68.2% of patients who did not have chronic hypoxemic respiratory failure before SABR, 16% developed a new requirement for supplemental oxygen. Sixty-two tumors (89.9%) were peripheral. There were 4 local recurrences (5.7%), 10 regional (different lobe and nodal) failures (14.3%), and 15 distant metastases (21.4%).

Nineteen of 67 patients (26.3%) had acute toxicity of which 9 had acute grade ≥ 2 toxicity; information regarding toxicity was missing on 2 patients. Thirty-two of 65 (49.9%) patients had late toxicity of which 20 (30.8%) had late grade ≥ 2 toxicity. The main factor associated with development of acute toxicity was pretreatment oxygendependence (P = .047). This was not significant when comparing only inoperable patients. Twenty patients (29.9%) developed some type of acute toxicity; pulmonary toxicity was most common (22.4%) (Table 3). All patients with acute toxicity also developed late toxicity except for 1 who died before 3 months. Predominantly, the deaths in our sample were from causes other than the malignancy or treatment, such as sepsis, deconditioning after a fall, cardiovascular complications, etc. Acute toxicity of grade ≥ 2 was significantly associated with late toxicity (P < .001 for both) in both operable and inoperable patients (P < .001).

Discussion

SABR is an effective treatment for inoperable early-stage NSCLC, however its therapeutic ratio in a more frail population who cannot withstand biopsy is not well established. Additionally, the prevalence of benign disease in patients with solitary pulmonary nodules can be between 9% and 21%.⁶ Haidar and colleagues looked at 55 patients who received empiric SABR and found a median OS of 30.2 months with an 8.7% risk of local failure, 13% risk of regional failure with 8.7% acute toxicity, and 13% chronic toxicity.⁷ Data from Harkenrider and colleagues (n = 34) revealed similar results with a 2-year OS of 85%, local control of 97.1%, and regional control of 80%. The authors noted no grade ≥ 3 acute toxicities and an incidence of grade ≥ 3 late toxicities of 8.8%.¹ These findings are concordant with our study results, confirming the safety and efficacy of SABR. Furthermore, a National Cancer Database analysis of observation vs empiric SABR found an OS of 10.1 months and 29 months respectively, with a hazard ratio of 0.64 (P < .001).³ Additionally, Fischer-Valuck and colleagues (n = 88) compared biopsy confirmed vs unbiopsied patients treated with SABR and found no difference in the 3-year local progression-free survival (93.1% vs 94.1%), regional lymph node metastasis and distant metastases free survival (92.5% vs 87.4%), or OS (59.9% vs 58.9%).⁸ With a median OS of ≤ 1 year for untreated stage I NSCLC,these studies support treating patients with empiric SABR.⁴

Other researchers have sought parameters to identify patients for whom radiation therapy would be too toxic. Guckenberger and colleagues aimed to establish a lower limit of pretreatment PFT to exclude patients and found only a 7% incidence of grade ≥ 2 adverse effects and toxicity did not increase with lower pulmonary function.⁹ They concluded that SABR was safe even for patients with poor pulmonary function. Other institutions have confirmed such findings and have been unable to find a cut-off PFT to exclude patients from empiric SABR.^10,11 An analysis from the RTOG 0236 trial also noted that poor baseline PFT could not predict pulmonary toxicity or survival. Additionally, the study demonstrated only minimal decreases in patients’ FEV₁ (5.8%) and DLCO (6%) at 2 years.¹²

Limitations

Our study is limited by caveats of a retrospective study and its small sample size, but is in line with the reported literature (ranging from 33 to 88 patients).^1,7,8 Another limitation is that data on pretreatment DLCO was missing in 37 patients and the lack of statistical robustness in terms of the smaller inoperable cohort, which limits the analyses of these factors in regards to anticipated morbidity from SABR. Also, given this is data collected from the US Department of Veterans Affairs, only 3% of our sample was female.

Conclusions

Empiric SABR for patients with presumed early-stage NSCLC appears to be safe and might positively impact OS. Development of any acute toxicity grade ≥ 2 was significantly associated with dependence on supplemental oxygen before treatment, central tumor location, and development of new oxygen requirement. No association was found in patients with poor pulmonary function before treatment because we could not find a FEV₁ or DLCO cutoff that could preclude patients from empiric SABR. Considering the poor survival of untreated early-stage NSCLC, coupled with the efficacy and safety of empiric SABR for those with presumed disease, definitive SABR should be offered selectively within this patient population.

Stereotactic ablative radiotherapy (SABR) has become the standard of care for inoperable early-stage non-small cell lung cancer (NSCLC). Many patients are unable to undergo a biopsy safely because of poor pulmonary function or underlying emphysema and are then empirically treated with radiotherapy if they meet criteria. In these patients, local control can be achieved with SABR with minimal toxicity.¹ Considering that median overall survival (OS) among patients with untreated stage I NSCLC has been reported to be as low as 9 months, early treatment with SABR could lead to increased survival of 29 to 60 months.^2-4

The RTOG 0236 trial showed a median OS of 48 months and the randomized phase III CHISEL trial showed a median OS of 60 months; however, these survival data were reported in patients who were able to safely undergo a biopsy and had confirmed NSCLC.^4,5 For patients without a diagnosis confirmed by biopsy and who are treated with empiric SABR, patient factors that influence radiation toxicity and OS are not well defined.

It is not clear if empiric radiation benefits survival or if treatment causes decline in lung function, considering that underlying chronic lung disease precludes these patients from biopsy. The purpose of this study was to evaluate the factors associated with radiation toxicity with empiric SABR and to evaluate OS in this population without a biopsy-confirmed diagnosis.

Methods

This was a single center retrospective review of patients treated at the radiation oncology department at the Kansas City Veterans Affairs Medical Center from August 2014 to February 2019. Data were collected on 69 patients with pulmonary nodules identified by chest computed tomography (CT) and/or positron emission tomography (PET)-CT that were highly suspicious for primary NSCLC.

These patients were presented at a multidisciplinary meeting that involved pulmonologists, oncologists, radiation oncologists, and thoracic surgeons. Patients were deemed to be poor candidates for biopsy because of severe underlying emphysema, which would put them at high risk for pneumothorax with a percutaneous needle biopsy, or were unable to tolerate general anesthesia for navigational bronchoscopy or surgical biopsy because of poor lung function. These patients were diagnosed with presumed stage I NSCLC using the criteria: minimum of 2 sequential CT scans with enlarging nodule; absence of metastases on PET-CT; the single nodule had to be fluorodeoxyglucose avid with a minimum standardized uptake value of 2.5, and absence of clinical history or physical examination consistent with small cell lung cancer or infection.

Evaluation of oral antineoplastic agent (OAN) adherence patterns have identified correlations between nonadherence or over-adherence and poorer disease-related outcomes. Multiple studies have focused on imatinib use in chronic myeloid leukemia (CML) due to its continuous, long-term use. A study by Ganesan and colleagues found that nonadherence to imatinib showed a significant decrease in 5-year event-free survival between 76.7% of adherent participants compared with 59.8% of nonadherent participants.¹ This study found that 44% of patients who were adherent to imatinib achieved complete cytogenetic response vs only 26% of patients who were nonadherent. In another study of imatinib for CML, major molecular response (MMR) was strongly correlated with adherence and no patients with adherence < 80% were able to achieve MMR.² Similarly, in studies of tamoxifen for breast cancer, < 80% adherence resulted in a 10% decrease in survival when compared to those who were more adherent.^3,4

In addition to the clinical implications of nonadherence, there can be a significant cost associated with suboptimal use of these medications. The price of a single dose of OAN medication may cost as much as $440.⁵

The benefits of multidisciplinary care teams have been identified in many studies.^6,7 While studies are limited in oncology, pharmacists provide vital contributions to the oncology multidisciplinary team when managing OANs as these health care professionals have expert knowledge of the medications, potential adverse events (AEs), and necessary monitoring parameters.⁸ In one study, patients seen by the pharmacist-led oral chemotherapy management program experienced improved clinical outcomes and response to therapy when compared with preintervention patients (early molecular response, 88.9% vs 54.8%, P = .01; major molecular response, 83.3% vs 57.6%, P = .06).⁹ During the study, 318 AEs were reported, leading to 235 pharmacist interventions to ameliorate AEs and improve adherence.

The primary objective of this study was to measure the impact of a pharmacist-driven OAN renewal clinic on medication adherence. The secondary objective was to estimate cost-savings of this new service.

Methods 

Prior to July 2014, several limitations were identified related to OAN prescribing and monitoring at the Richard L. Roudebush Veterans Affairs Medical Center in Indianapolis, Indiana (RLRVAMC). The prescription ordering process relied primarily on the patient to initiate refills, rather than the prescriber OAN prescriptions also lacked consistency for number of refills or quantities dispensed. Furthermore, ordering of antineoplastic products was not limited to hematology/oncology providers. Patients were identified with significant supply on hand at the time of medication discontinuation, creating concerns for medication waste, tolerability, and nonadherence.

As a result, opportunities were identified to improve the prescribing process, recommended monitoring, toxicity and tolerability evaluation, medication reconciliation, and medication adherence. In July of 2014, the RLRVAMC adopted a new chemotherapy order entry system capable of restricting prescriptions to hematology/oncology providers and limiting dispensed quantities and refill amounts. A comprehensive pharmacist driven OAN renewal clinic was implemented on September 1, 2014 with the goal of improving long-term adherence and tolerability, in addition to minimizing medication waste.

Study Design and Setting

This was a pre/post retrospective cohort, quality improvement study of patients enrolled in the RLRVAMC OAN pharmacist renewal clinic. The study was deemed exempt from institutional review board (IRB) by the US Department of Veterans Affairs (VA) Research and Development Department.

Study Population

Patients were included in the preimplementation group if they had received at least 2 prescriptions of an eligible OAN. Therapy for the preimplementation group was required to be a monthly duration > 21 days and between the dates of September 1, 2013 and August 31, 2014. Patients were included in the postimplementation group if they had received at least 2 prescriptions of the studied OANs between September 1, 2014 and January 31, 2015. Patients were excluded if they had filled < 2 prescriptions of OAN; were managed by a non-VA oncologist or hematologist; or received an OAN other than those listed in Table 1.

Data Collection

For all patients in both the pre- and postimplementation cohorts, a standardized data collection tool was used to collect the following via electronic health record review by a PGY2 oncology resident: age, race, gender, oral antineoplastic agent, refill dates, days’ supply, estimated unit cost per dose cancer diagnosis, distance from the RLRVAMC, copay status, presence of hospitalizations/ED visits/dosage reductions, discontinuation rates, reasons for discontinuation, and total number of current prescriptions. The presence or absence of dosage reductions were collected to identify concerns for tolerability, but only the original dose for the preimplementation group and dosage at time of clinic enrollment for the postimplementation group was included in the analysis.

Outcomes and Statistical Analyses

The primary outcome was medication adherence defined as the median medication possession ratio (MPR) before and after implementation of the clinic. Secondary outcomes included the proportion of patients who were adherent from before implementation to after implementation and estimated cost-savings of this clinic after implementation. MPR was used to estimate medication adherence by taking the cumulative day supply of medication on hand divided by the number of days on therapy.¹² Number of days on therapy was determined by taking the difference on the start date of the new medication regimen and the discontinuation date of the same regimen. Patients were grouped by adherence into one of the following categories: < 0.8, 0.8 to 0.89, 0.9 to 1, and > 1.1. Patients were considered adherent if they reported taking ≥ 90% (MPR ≥ 0.9) of prescribed doses, adopted from the study by Anderson and colleagues.¹² A patient with an MPR > 1, likely due to filling prior to the anticipated refill date, was considered 100% adherent (MPR = 1). If a patient switched OAN during the study, both agents were included as separate entities.

A conservative estimate of cost-savings was made by multiplying the RLRVAMC cost per unit of medication at time of initial prescription fill by the number of units taken each day multiplied by the total days’ supply on hand at time of therapy discontinuation. Patients with an MPR < 1 at time of therapy discontinuation were assumed to have zero remaining units on hand and zero cost savings was estimated. Waste, for purposes of cost-savings, was calculated for all MPR values > 1. Additional supply anticipated to be on hand from dose reductions was not included in the estimated cost of unused medication.

Descriptive statistics compared demographic characteristics between the pre- and postimplementation groups. MPR data were not normally distributed, which required the use of nonparametric Mann-Whitney U tests to compare pre- and postMPRs. Pearson χ² compared the proportion of adherent patients between groups while descriptive statistics were used to estimate cost savings. Significance was determined based on a P value < .05. IBM SPSS Statistics software was used for all statistical analyses. As this was a complete sample of all eligible subjects, no sample size calculation was performed.

Results

In the preimplementation period, 246 patients received an OAN and 61 patients received an OAN in the postimplementation period (Figure 1). Of the 246 patients in the preimplementation period, 98 were eligible and included in the preimplementation group. Similarly, of the 61 patients in the postimplementation period, 35 patients met inclusion criteria for the postimplementation group. The study population was predominantly male with an average age of approximately 70 years in both groups (Table 3). More than 70% of the population in each group was White. No statistically significant differences between groups were identified. The most commonly prescribed OAN in the preimplementation group were abiraterone, imatinib, and enzalutamide (Table 3). In the postimplementation group, the most commonly prescribed agents were abiraterone, imatinib, pazopanib, and dasatinib. No significant differences were observed in prescribing of individual agents between the pre- and postimplementation groups or other characteristics that may affect adherence including patient copay status, number of concomitant medications, and driving distance from the RLRVAMC.

Thirty-six (36.7%) patients in the preimplementation group were considered nonadherent (MPR < 0.9) and 18 (18.4%) had an MPR < 0.8. Fifteen (15.3%) patients in the preimplementation clinic were considered overadherent (MPR > 1.1). Forty-seven (47.9%) patients in the preimplementation group were considered adherent (MPR 0.9 - 1.1) while all 35 (100%) patients in the postimplementation group were considered adherent (MPR 0.9 - 1.1). No non- or overadherent patients were identified in the postimplementation group (Figure 2). The median MPR for all patients in the preimplementation group was 0.94 compared with 1.06 (P < .001) in the postimplementation group.

Discussion

OANs are widely used therapies, with more than 25 million doses administered per year in the United States alone.¹² The use of these agents will continue to grow as more targeted agents become available and patients request more convenient treatment options. The role for hematology/oncology clinical pharmacy services must adapt to this increased usage of OANs, including increasing pharmacist involvement in medication education, adherence and tolerability assessments, and proactive drug interaction monitoring.However, additional research is needed to determine optimal management strategies.

Our study aimed to compare OAN adherence among patients at a tertiary care VA hospital before and after implementation of a renewal clinic. The preimplementation population had a median MPR of 0.94 compared with 1.06 in the postimplementation group (P < .001). Although an ideal MPR is 1.0, we aimed for a slightly higher MPR to allow a supply buffer in the event of prescription delivery delays, as more than 90% of prescriptions are mailed to patients from a regional mail-order pharmacy. Importantly, the median MPRs do not adequately convey the impact from this clinic. The proportion of patients who were considered adherent to OANs increased from 47.9% in the preimplementation to 100% in the postimplementation period. These finding suggest that the clinical pharmacist role to assess and encourage adherence through monitoring tolerability of these OANs improved the overall medication taking experience of these patients.

Upon initial evaluation of adherence pre- and postimplementation, median adherence rates in both groups appeared to be above goal at 0.94 and 1.06 respectively. Patients in the postimplementation group intentionally received a 5- to 7-day supply buffer to account for potential prescription delivery delays due to holidays and inclement weather. This would indicate that the patients in the postimplementation group would have 15% oversupply due to the 5-day supply buffer. After correcting for patients with confounding reasons for excess (dose reductions, breaks in treatment, etc.), the median MPR in the prerefill clinic group decreased to 0.9 and the MPR in the postrefill clinic group increased slightly to 1.08. Although the median adherence rate in both the pre- and postimplementation groups were above goal of 0.90, 36% of the patients in the preimplementation group were considered nonadherent (MPR < 0.9) compared with no patients in the postimplementation group. Therefore, our intervention to improve patient adherence appeared to be beneficial at our institution.

In addition to improving adherence, one of the goals of the renewal clinic was to minimize excess supply at the time of therapy discontinuation. This was accomplished by aligning medication fills with medical visits and objective monitoring, as well as limiting supply to no more than 30 days. Of the patients in the postimplementation group, only 1 patient had remaining medication at the time of therapy discontinuation compared with 14 patients in the preimplementation group. The estimated cost savings from excess supply was $36,335. Limiting the amount of unused supply not only saves money for the patient and the institution, but also decreases opportunity for improper hazardous waste disposal and unnecessary exposure of hazardous materials to others.

Our results show the pharmacist intervention in the coordination of renewals improved adherence, minimized medication waste, and saved money. The cost of pharmacist time participating in the refill clinic was not calculated. Each visit was completed in approximately 5 minutes, with subsequent documentation and coordination taking an additional 5 to 10 minutes. During the launch of this service, the oncology pharmacy resident provided all coverage of the clinic. Oversite of the resident was provided by hematology/oncology clinical pharmacy specialists. We have continued to utilize pharmacy resident coverage since that time to meet education needs and keep the estimated cost per visit low. Another option in the case that pharmacy residents are not available would be utilization of a pharmacy technician, intern, or professional student to conduct the adherence and tolerability phone assessments. Our escalation protocol allows intervention by clinical pharmacy specialist and/or other health care providers when necessary. Trainees have only required basic training on how to use the protocol.

Limitations

Due to this study’s retrospective design, an inherent limitation is dependence on prescriber and refill records for documentation of initiation and discontinuation dates. Therefore, only the association of impact of pharmacist intervention on medication adherence can be determined as opposed to causation. We did not take into account discrepancies in day supply secondary to ‘held’ therapies, dose reductions, or doses supplied during an inpatient admission, which may alter estimates of MPR and cost-savings data. Patients in the postimplementation group intentionally received a 5 to 7-day supply buffer to account for potential prescription delivery delays due to holidays and inclement weather. This would indicate that the patients in the postimplementation group would have 15% oversupply due to the 5-day supply buffer, thereby skewing MPR values. This study did not account for cost avoidance resulting from early identification and management of toxicity. Finally, the postimplementation data only spans 4 months and a longer duration of time is needed to more accurately determine sustainability of renewal clinic interventions and provide comprehensive evaluation of cost-avoidance.

Conclusion

Implementation of an OAN renewal clinic was associated with an increase in MPR, improved proportion of patients considered adherent, and an estimated $36,335 cost-savings. However, prospective evaluation and a longer study duration are needed to determine causality of improved adherence and cost-savings associated with a pharmacist-driven OAN renewal clinic.

Evaluation of oral antineoplastic agent (OAN) adherence patterns have identified correlations between nonadherence or over-adherence and poorer disease-related outcomes. Multiple studies have focused on imatinib use in chronic myeloid leukemia (CML) due to its continuous, long-term use. A study by Ganesan and colleagues found that nonadherence to imatinib showed a significant decrease in 5-year event-free survival between 76.7% of adherent participants compared with 59.8% of nonadherent participants.¹ This study found that 44% of patients who were adherent to imatinib achieved complete cytogenetic response vs only 26% of patients who were nonadherent. In another study of imatinib for CML, major molecular response (MMR) was strongly correlated with adherence and no patients with adherence < 80% were able to achieve MMR.² Similarly, in studies of tamoxifen for breast cancer, < 80% adherence resulted in a 10% decrease in survival when compared to those who were more adherent.^3,4

In addition to the clinical implications of nonadherence, there can be a significant cost associated with suboptimal use of these medications. The price of a single dose of OAN medication may cost as much as $440.⁵

The benefits of multidisciplinary care teams have been identified in many studies.^6,7 While studies are limited in oncology, pharmacists provide vital contributions to the oncology multidisciplinary team when managing OANs as these health care professionals have expert knowledge of the medications, potential adverse events (AEs), and necessary monitoring parameters.⁸ In one study, patients seen by the pharmacist-led oral chemotherapy management program experienced improved clinical outcomes and response to therapy when compared with preintervention patients (early molecular response, 88.9% vs 54.8%, P = .01; major molecular response, 83.3% vs 57.6%, P = .06).⁹ During the study, 318 AEs were reported, leading to 235 pharmacist interventions to ameliorate AEs and improve adherence.

The primary objective of this study was to measure the impact of a pharmacist-driven OAN renewal clinic on medication adherence. The secondary objective was to estimate cost-savings of this new service.

Methods 

Prior to July 2014, several limitations were identified related to OAN prescribing and monitoring at the Richard L. Roudebush Veterans Affairs Medical Center in Indianapolis, Indiana (RLRVAMC). The prescription ordering process relied primarily on the patient to initiate refills, rather than the prescriber OAN prescriptions also lacked consistency for number of refills or quantities dispensed. Furthermore, ordering of antineoplastic products was not limited to hematology/oncology providers. Patients were identified with significant supply on hand at the time of medication discontinuation, creating concerns for medication waste, tolerability, and nonadherence.

As a result, opportunities were identified to improve the prescribing process, recommended monitoring, toxicity and tolerability evaluation, medication reconciliation, and medication adherence. In July of 2014, the RLRVAMC adopted a new chemotherapy order entry system capable of restricting prescriptions to hematology/oncology providers and limiting dispensed quantities and refill amounts. A comprehensive pharmacist driven OAN renewal clinic was implemented on September 1, 2014 with the goal of improving long-term adherence and tolerability, in addition to minimizing medication waste.

Study Design and Setting

This was a pre/post retrospective cohort, quality improvement study of patients enrolled in the RLRVAMC OAN pharmacist renewal clinic. The study was deemed exempt from institutional review board (IRB) by the US Department of Veterans Affairs (VA) Research and Development Department.

Study Population

Patients were included in the preimplementation group if they had received at least 2 prescriptions of an eligible OAN. Therapy for the preimplementation group was required to be a monthly duration > 21 days and between the dates of September 1, 2013 and August 31, 2014. Patients were included in the postimplementation group if they had received at least 2 prescriptions of the studied OANs between September 1, 2014 and January 31, 2015. Patients were excluded if they had filled < 2 prescriptions of OAN; were managed by a non-VA oncologist or hematologist; or received an OAN other than those listed in Table 1.

Data Collection

For all patients in both the pre- and postimplementation cohorts, a standardized data collection tool was used to collect the following via electronic health record review by a PGY2 oncology resident: age, race, gender, oral antineoplastic agent, refill dates, days’ supply, estimated unit cost per dose cancer diagnosis, distance from the RLRVAMC, copay status, presence of hospitalizations/ED visits/dosage reductions, discontinuation rates, reasons for discontinuation, and total number of current prescriptions. The presence or absence of dosage reductions were collected to identify concerns for tolerability, but only the original dose for the preimplementation group and dosage at time of clinic enrollment for the postimplementation group was included in the analysis.

Outcomes and Statistical Analyses

The primary outcome was medication adherence defined as the median medication possession ratio (MPR) before and after implementation of the clinic. Secondary outcomes included the proportion of patients who were adherent from before implementation to after implementation and estimated cost-savings of this clinic after implementation. MPR was used to estimate medication adherence by taking the cumulative day supply of medication on hand divided by the number of days on therapy.¹² Number of days on therapy was determined by taking the difference on the start date of the new medication regimen and the discontinuation date of the same regimen. Patients were grouped by adherence into one of the following categories: < 0.8, 0.8 to 0.89, 0.9 to 1, and > 1.1. Patients were considered adherent if they reported taking ≥ 90% (MPR ≥ 0.9) of prescribed doses, adopted from the study by Anderson and colleagues.¹² A patient with an MPR > 1, likely due to filling prior to the anticipated refill date, was considered 100% adherent (MPR = 1). If a patient switched OAN during the study, both agents were included as separate entities.

A conservative estimate of cost-savings was made by multiplying the RLRVAMC cost per unit of medication at time of initial prescription fill by the number of units taken each day multiplied by the total days’ supply on hand at time of therapy discontinuation. Patients with an MPR < 1 at time of therapy discontinuation were assumed to have zero remaining units on hand and zero cost savings was estimated. Waste, for purposes of cost-savings, was calculated for all MPR values > 1. Additional supply anticipated to be on hand from dose reductions was not included in the estimated cost of unused medication.

Descriptive statistics compared demographic characteristics between the pre- and postimplementation groups. MPR data were not normally distributed, which required the use of nonparametric Mann-Whitney U tests to compare pre- and postMPRs. Pearson χ² compared the proportion of adherent patients between groups while descriptive statistics were used to estimate cost savings. Significance was determined based on a P value < .05. IBM SPSS Statistics software was used for all statistical analyses. As this was a complete sample of all eligible subjects, no sample size calculation was performed.

Results

In the preimplementation period, 246 patients received an OAN and 61 patients received an OAN in the postimplementation period (Figure 1). Of the 246 patients in the preimplementation period, 98 were eligible and included in the preimplementation group. Similarly, of the 61 patients in the postimplementation period, 35 patients met inclusion criteria for the postimplementation group. The study population was predominantly male with an average age of approximately 70 years in both groups (Table 3). More than 70% of the population in each group was White. No statistically significant differences between groups were identified. The most commonly prescribed OAN in the preimplementation group were abiraterone, imatinib, and enzalutamide (Table 3). In the postimplementation group, the most commonly prescribed agents were abiraterone, imatinib, pazopanib, and dasatinib. No significant differences were observed in prescribing of individual agents between the pre- and postimplementation groups or other characteristics that may affect adherence including patient copay status, number of concomitant medications, and driving distance from the RLRVAMC.

Thirty-six (36.7%) patients in the preimplementation group were considered nonadherent (MPR < 0.9) and 18 (18.4%) had an MPR < 0.8. Fifteen (15.3%) patients in the preimplementation clinic were considered overadherent (MPR > 1.1). Forty-seven (47.9%) patients in the preimplementation group were considered adherent (MPR 0.9 - 1.1) while all 35 (100%) patients in the postimplementation group were considered adherent (MPR 0.9 - 1.1). No non- or overadherent patients were identified in the postimplementation group (Figure 2). The median MPR for all patients in the preimplementation group was 0.94 compared with 1.06 (P < .001) in the postimplementation group.
