Clinical question: Can a multifaceted intervention by a clinical pharmacist reduce the rate of ED visits and readmission over the subsequent 180 days?

Background: The period following an inpatient admission contains many potential risks for patients, among them the risk for adverse drug events. Approximately 45% of readmissions from adverse drug reactions are thought to be avoidable.

Study design: Multicentered, single-blinded, randomized, control trial, from September 2013 to April 2015.

Setting: Four acute inpatient hospitals in Denmark.

Synopsis: 1,467 adult patients being admitted for an acute hospitalization on a minimum of five medications were randomized to receive usual care, a basic intervention (medication review by a clinical pharmacist), or an extended intervention (medication review, three motivational interviews, and follow-up with the primary care physician, pharmacy and, if appropriate, nursing home by a clinical pharmacist). The primary endpoints were readmission within 30 days or 180 days, ED visits within 180 days, and a composite endpoint of readmission or ED visit within 180 days post discharge. For these endpoints, the basic intervention group had no statistically significant difference from the usual-care group. The extended intervention group had significantly lower rates of readmission within 30 days and 180 days, as well as the primary composite endpoint compared to the usual-care group (P less than .05 for all comparisons). For the extended intervention, the number needed to treat for the main composite endpoint was 12.

Bottom line: For patients admitted to the hospital, an extended intervention by a clinical pharmacist resulted in a significant reduction in readmissions.

Micrograph showing FL

A multidrug regimen can improve upon involved-field radiotherapy (IFRT) in patients with early stage follicular lymphoma (FL), according to research published in the Journal of Clinical Oncology.

FL patients who received IFRT plus cyclophosphamide, vincristine, and prednisolone (CVP)—with or without rituximab—had a significant improvement in progression-free survival (PFS) compared to patients who received standard treatment with IFRT alone.

However, there was no significant difference in overall survival (OS) between the treatment arms.

“This is the first successful randomized study ever to be conducted in early stage follicular lymphoma comparing standard therapy to standard therapy plus effective chemotherapy or immunochemotherapy,” said Michael MacManus, MBBCh, of Peter MacCallum Cancer Centre in Melbourne, Victoria, Australia.

“It shows that the initial treatment received by patients can significantly affect their long-term chance of staying free from disease. Moving forward, we are interested in determining whether there is a benefit in overall long-term survival for patients treated with the combination with further follow-up, and if there is any way to predict if a person will benefit from combined treatment based on analyses of blood or biopsy specimens.”

Dr MacManus and his colleagues studied 150 patients with stage I to II, low-grade FL who were enrolled in this trial between 2000 and 2012.

At randomization, the patients’ median age was 57, 52% were male, 75% had stage I disease, and 48% had PET staging.

Half of patients (n=75) were randomized to receive IFRT (30-36 Gy) alone, and half were randomized to IFRT (30-36 Gy) plus 6 cycles of CVP. From 2006 on, patients in the CVP arm received rituximab (R) as well (n=31).

Baseline characteristics were well-balanced between the treatment arms.

Efficacy

The median follow-up was 9.6 years (range, 3.1 to 15.8 years).

PFS was significantly better among patients randomized to receive CVP±R (hazard ratio [HR]=0.57; P=0.033). The estimated 10-year PFS rate was 41% in the IFRT arm and 59% in the CVP±R arm.

Patients randomized to receive CVP plus R (n=31) had significantly better PFS than patients randomized to receive IFRT alone (n=31) over the same time period (HR=0.26; P=0.045).

There were 10 deaths in the IRFT arm and 5 in the CVP±R arm, but there was no significant difference in OS between the arms (HR=0.62; P=0.40). The 10-year OS rate was 86% in the IFRT arm and 95% in the CVP±R arm.

There was no significant between-arm difference in transformation to aggressive lymphoma (P=0.1). Transformation occurred in 10 patients in the IFRT arm and 4 in the CVP±R arm.

Safety

There were 148 patients from both arms who ultimately received IFRT, and 69 patients who received CVP±R.

Grade 2 toxicities occurring in more than 10% of IFRT recipients included upper gastrointestinal (n=27; 18%), skin (n=21; 14%), and mucous membrane (n=19; 12%) toxicity. One IFRT recipient had grade 3 mucositis, and 1 had grade 4 esophageal/pharyngeal mucosal toxicity.

Grade 3 toxicities occurring in at least 2 patients in the CVP±R arm included neutropenia (n=10; 14%), infection (n=8; 12%), diarrhea (n=3; 4%), elevated gamma-glutamyl transferase (n=3; 4%), fatigue (n=3; 4%), and febrile neutropenia (n=3; 4%).

Three patients (4%) in the CVP±R arm had acute grade 3 neuropathy related to vincristine. Ten patients (14%) had grade 4 neutropenia.

The most common late toxicities for the entire patient cohort were salivary gland (n=8; 5%) and skin (n=4; 3%) toxicities.

Grade 3 lung and menopausal toxicities occurred in 1 patient each. Two patients had late grade 3 vincristine neuropathy. One patient who had grade 3 neuropathy during chemotherapy progressed to grade 4.

Health-related financial hardship is common among adult survivors of childhood cancer, according to a study published in the Journal of the National Cancer Institute.

Researchers analyzed more than 2800 long-term childhood cancer survivors (CCSs) and found that 65% had financial challenges related to their cancer diagnosis.

“These findings suggest primary care doctors and oncologists should routinely screen childhood cancer survivors for possible financial hardship,” said I-Chan Huang, PhD, of St. Jude Children’s Research Hospital in Memphis, Tennessee.

Specifically, Dr Huang recommends that healthcare providers routinely ask CCSs if they are unable to purchase medications, ever skip appointments for economic reasons, or worry about how to pay their medical bills.

For this study, Dr Huang and his colleagues analyzed data from 2811 CCSs. The subjects had a mean age of 31.8 (range, 18 to 65) and were a mean of 23.6 years from cancer diagnosis. Most (57.8%) had been diagnosed with hematologic malignancies, 32.0% with solid tumors, and 10.1% with central nervous system malignancies.

All subjects had been treated at St. Jude and enrolled in the St. Jude LIFE study. Participants return to St. Jude periodically for several days of clinical and functional assessments. Data for this study were collected during the CCSs’ first St. Jude LIFE evaluations.

Assessing hardship

The researchers measured 3 types of financial hardship—material, psychological, and coping/behavioral.

About 1 in 5 CCSs (22.4%) reported material financial hardship. In other words, their cancer had an impact on their financial situation.

More than half of CCSs (51.1%) reported psychological hardship—concern about their ability to pay for medical expenses.

And 33% of CCSs reported coping/behavioral hardship—an inability to see a doctor or go to the hospital due to finances.

Roughly 65% of CCSs reported at least 1 type of financial hardship.

All 3 types of hardship were significantly associated with somatization (all P<0.001), anxiety (all P<0.001), depression (all P<0.001), suicidal thoughts (all P<0.05), and difficulty in retirement planning (all P<0.001).

Furthermore, CCSs who reported financial hardship had significantly lower health-related quality of life (P<0.001 for all 3 domains), sensation abnormality (all P<0.001), pulmonary symptoms (all P<0.05), and cardiac symptoms (all P<0.05).

Predicting hardship

Intensive cancer treatment, chronic health conditions, second cancers, age at the time of study evaluation, education level, and annual household income were all significantly associated with a greater risk of financial hardship.

CCSs age 40 and older had an increased risk of psychological and coping/behavioral hardship (P<0.001 for both domains).

CCSs with an annual household income of less than $40,000 had an increased risk of material, psychological, and coping/behavioral hardship, compared to CCSs with an income of $80,000 or more (P<0.001 for all domains).

CCSs who did not obtain a high school diploma had an increased risk of material (P<0.001), psychological (P<0.01), and coping/behavioral hardship (P<0.001) compared to college graduates.

CCSs who received cancer treatments associated with a high-risk disease burden (vs low-risk) had an increased risk of material (P=0.01) and psychological (P=0.004) hardship.

Health conditions associated with material financial hardship included grade 2-4 myocardial infarction (P<0.001), peripheral neuropathy (P<0.001), subsequent neoplasm (P<0.001), seizure (P=0.007), reproductive disorders (P=0.01), stroke (P=0.02), amputation (P=0.02), upper gastrointestinal disease (P=0.04), and hearing loss (P=0.05).

Grade 2-4 myocardial infarction and reproductive disorders were significantly associated with psychological financial hardship (P=0.02 for both).

“Severe late effects that emerge early in life and disrupt education and training opportunities are a double hit for survivors,” Dr Huang said. “These health problems decrease the survivors’ earning mobility and financial security later in life. The phenomenon leaves them at risk for poor health and psychological outcomes compared to healthier survivors.”

AML cells

The US Food and Drug Administration (FDA) has granted breakthrough therapy designation to quizartinib, an investigational FLT3 inhibitor, for the treatment of adults with relapsed/refractory FLT3-ITD acute myeloid leukemia (AML).

The FDA granted quizartinib breakthrough designation based on results from the phase 3 QuANTUM-R study, which were presented at the 23rd Congress of the European Hematology Association in June.

QuANTUM-R enrolled adults with FLT3-ITD AML (at least 3% FLT3-ITD allelic ratio) who had refractory disease or had relapsed within 6 months of their first complete remission.

Patients were randomized to receive once-daily treatment with quizartinib (n=245) or a salvage chemotherapy regimen (n=122)—low-dose cytarabine (LoDAC, n=29); combination mitoxantrone, etoposide, and cytarabine (MEC, n=40); or combination fludarabine, cytarabine, and idarubicin (FLAG-IDA, n=53).

Responders could proceed to hematopoietic stem cell transplant (HSCT), and those in the quizartinib arm could resume quizartinib after HSCT. Thirty-two percent of quizartinib-treated patients and 12% of the chemotherapy group went on to HSCT.

The median follow-up was 23.5 months. The efficacy results include all randomized patients.

The overall response rate was 69% in the quizartinib arm and 30% in the chemotherapy arm. The complete response (CR) rate was 4% and 1%, respectively; the rate of CR with incomplete platelet recovery was 4% and 0%, respectively; and the rate of CR with incomplete hematologic recovery was 40% and 26%, respectively.

The median overall survival was 6.2 months in the quizartinib arm and 4.7 months in the chemotherapy arm (hazard ratio=0.76, P=0.0177). The 1-year overall survival rate was 27% and 20%, respectively.

The median event-free survival was 6.0 weeks in the quizartinib arm and 3.7 weeks in the chemotherapy arm (hazard ratio=0.90, P=0.1071).

The safety results include only patients who received their assigned treatment—241 patients who received quizartinib and 94 who received salvage chemotherapy (22 on LoDAC, 25 on MEC, and 47 on FLAG-IDA).

Grade 3 or higher hematologic treatment-emergent adverse events occurring in at least 5% of patients (in the quizartinib and chemotherapy groups, respectively) included thrombocytopenia (35% and 34%), anemia (30% and 29%), neutropenia (32% and 25%), febrile neutropenia (31% and 21%), and leukopenia (17% and 16%).

Grade 3 or higher nonhematologic treatment-emergent adverse events occurring in at least 5% of patients (in the quizartinib and chemotherapy groups, respectively) included fatigue (8% and 1%), hypokalemia (12% and 9%), sepsis/septic shock (16% and 18%), dyspnea (5% for both), hypophosphatemia (5% for both), and pneumonia (12% and 9%).

Three percent of patients in the quizartinib arm had grade 3 QTcF prolongation, and 2 patients discontinued quizartinib due to QTcF prolongation.

About breakthrough designation

Breakthrough designation is intended to expedite the development and review of new treatments for serious or life-threatening conditions.

The designation entitles the company developing a therapy to more intensive FDA guidance on an efficient and accelerated development program, as well as eligibility for other actions to expedite FDA review, such as rolling submission and priority review.

To earn breakthrough designation, a treatment must show encouraging early clinical results demonstrating substantial improvement over available therapies with regard to a clinically significant endpoint, or it must fulfill an unmet need.

Other designations for quizartinib

In addition to breakthrough therapy designation, quizartinib has fast track and orphan drug designations from the FDA.

The FDA’s fast track development program is designed to expedite clinical development and submission of applications for products with the potential to treat serious or life-threatening conditions and address unmet medical needs.

Fast track designation facilitates frequent interactions with the FDA review team, including meetings to discuss the product’s development plan and written communications about issues such as trial design and use of biomarkers.

Products that receive fast track designation may be eligible for accelerated approval and priority review if relevant criteria are met. Such products may also be eligible for rolling review, which allows a developer to submit individual sections of a product’s application for review as they are ready, rather than waiting until all sections are complete.

The FDA grants orphan designation to products intended to treat, diagnose, or prevent diseases/disorders that affect fewer than 200,000 people in the US.

Orphan designation provides incentives for sponsors to develop products for rare diseases. This may include tax credits toward the cost of clinical trials, prescription drug user fee waivers, and 7 years of market exclusivity if the product is approved.

AML cells

The US Food and Drug Administration (FDA) has granted breakthrough therapy designation to quizartinib, an investigational FLT3 inhibitor, for the treatment of adults with relapsed/refractory FLT3-ITD acute myeloid leukemia (AML).

The FDA granted quizartinib breakthrough designation based on results from the phase 3 QuANTUM-R study, which were presented at the 23rd Congress of the European Hematology Association in June.

QuANTUM-R enrolled adults with FLT3-ITD AML (at least 3% FLT3-ITD allelic ratio) who had refractory disease or had relapsed within 6 months of their first complete remission.

Patients were randomized to receive once-daily treatment with quizartinib (n=245) or a salvage chemotherapy regimen (n=122)—low-dose cytarabine (LoDAC, n=29); combination mitoxantrone, etoposide, and cytarabine (MEC, n=40); or combination fludarabine, cytarabine, and idarubicin (FLAG-IDA, n=53).

Responders could proceed to hematopoietic stem cell transplant (HSCT), and those in the quizartinib arm could resume quizartinib after HSCT. Thirty-two percent of quizartinib-treated patients and 12% of the chemotherapy group went on to HSCT.

The median follow-up was 23.5 months. The efficacy results include all randomized patients.

The overall response rate was 69% in the quizartinib arm and 30% in the chemotherapy arm. The complete response (CR) rate was 4% and 1%, respectively; the rate of CR with incomplete platelet recovery was 4% and 0%, respectively; and the rate of CR with incomplete hematologic recovery was 40% and 26%, respectively.

The median overall survival was 6.2 months in the quizartinib arm and 4.7 months in the chemotherapy arm (hazard ratio=0.76, P=0.0177). The 1-year overall survival rate was 27% and 20%, respectively.

Each time this 32-year-old woman has a baby—she’s had four to date—she notices that sections of her face darken. Early on, she observed a pattern in which the coming of winter coincided with a lightening of these affected areas—but now the effect lasts year-round, with progressive darkening. She has not tried any products (OTC or prescription) for this problem.

Growing up in the South, the patient and her family spent most summers boating, swimming, and fishing. Her use of sunscreen was sporadic, but she would tan easily regardless.

Her health is good, aside from a 15-year history of smoking.

EXAMINATION
There is excessive hyperpigmentation (brown) on the patient’s face. It follows a mask-like pattern, including her maxilla and the periphery of her face.

Elsewhere, there is abundant evidence of excessive sun exposure, with focal hyperpigmentation and telangiectasias on her arms. She has type IV skin, consistent with her Native American ancestry.

What is the diagnosis?

DISCUSSION
Melasma, also known as chloasma and dubbed the “mask of pregnancy,” is an extremely common problem that results from a combination of naturally dark skin, lots of sun exposure, and increased levels of estrogenic hormones. The latter can result from pregnancy or from oral contraceptive or estrogen replacement therapy use. Another precipitating factor is thyroid disease, certain types of which lead to an increase in melanocytic stimulating hormone.

Melasma, as one might expect, is seen almost exclusively in women, though a rare male is affected. It is especially common among Latina, Native American, and African-American women, whose melanocytes are especially able to produce pigment.

There are several treatments for melasma, none of them perfect, including tretinoin, azelaic acid, chemical peels, dermabrasion, and lasers. The most common treatment is hydroquinone cream, available in the US in both OTC (2%) and prescription (4%) strengths. However, hydroquinone is available OTC in stronger formulations (15% to 20%) in many Central and South American countries; unfortunately, many women who obtain and use these products experience exogenous ochronosis—a worsening or even precipitation of melasma, resulting from excessive production of tyrosinase.

Any treatment must be used in conjunction with rigorous sunscreen application. A full-spectrum product, with titanium dioxide and zinc oxide as the only active ingredients, must be used, because chemical-laden sunscreens don’t do as good a job covering UVA, UVB, and visible light. Convincing women who are unaccustomed to needing sunscreen to use it religiously is part of what makes treating melasma difficult.

The differential for melasma includes postinflammatory hyperpigmentation (eg, following an episode of contact dermatitis) and simple solar lentigines.

This patient was treated with hydroquinone 4% cream bid, plus sunscreen. She was also given information about other treatment options, such as laser and dermabrasion.

TAKE-HOME LEARNING POINTS

• Melasma, also known at chloasma, is quite common, especially among women with darker skin who live in sunny parts of the world.
• It results from a combination of dark skin, an increased level of estrogenic hormones (eg, with pregnancy, birth control pills, or estrogen replacement therapy), and excessive exposure to UV light.
• While hydroquinone cream can be an effective treatment, the maximum strength should be 4%; overuse of stronger concentrations (available in other countries, such as Mexico), can actually cause melasma to worsen.

I read “Up In Arms About Gun Violence” in the May/June issue of Clinician Reviews with great interest. My response is drawn from research, professional experience, and three particularly formative experiences:

• The birth of a child with learning and behavioral differences requiring an individualized education program and temporary placement in an alternative school.
• Co-leading a parent workshop for my clinical Capstone project.
• A nonclinical position at a public alternative school for children with emotional and behavioral disorders.

In nursing, as in all human services, we strive to be holistic, drawing from science, research, ethics, human development, sociology, anthropology, etc, to function in our roles. Many in nursing have come to value and function well in multidisciplinary teams for the management of individuals with complex needs.

What I have learned in my life—a fact supported by my professional preparation—is that the cycle of poverty, poor health, and quality of life are greatly influenced by education. During my pediatrics rotation and clinical, I learned you must consider family to be the vehicle by which the child may benefit from your clinical services. Therefore, you must reach beyond your setting in an effective and consistent way to engage, connect the home, and then follow up for response. My colleagues are aware of the need to document and the processes currently available for health, social service, and school professionals to report concerns. Too often, obstacles and other influences stand in the way of our ethical duty as professionals; we must find a way to overcome them, both individually and as a group.

We have processes for adolescents aging out of foster care and the developmentally delayed transitioning to sheltered work; can these be expanded?

My experience in a public school district’s alternative school for children in grades 6-12 opened my eyes to the need for the public to understand how these schools function. I likened these schools to the intensive care unit in the acute care setting. Smaller population, high needs, high cost, and dedicated staff but high burnout and turnover. Children in my school came from foster care or struggling homes and often had experienced trauma. Underfunded school districts cut nurses and social workers, cannot attract professional support staff, and choose to distribute money and efforts on the general population in neighborhood schools.

My “professional health care” mindset was embedded in an environment of wounded children, amazing educators, and support staff; powerless to do our best, we held on. But it is not enough to just hold on, sequestering at-risk children out of sight. We can do better.

Continue to: Some ideas to turn this belief into reality

Some ideas to turn this belief into reality:

1. Create position statements and recommendations for our licensing and professional certifying bodies to share with their membership.
2. Include mandates for communicating those recommendations during certification and relicensing.
3. Employ district staff or contracted consulting medical and psychologic evaluators for review of public school students with health and behavioral diagnoses.
4. Partner better with schools from the community health, pediatrician, behavioral health, and primary care settings. Kennedy Krieger Institute has partnered with schools in Baltimore—can this be replicated elsewhere?
5. Every child enters school with a need for health clearance and a “Guardian Permission Contact Card.” Perhaps we can expand this to develop a process for results of routine assessments to be shared, for the safety and welfare of the child.
6. Teach individuals to cope effectively with the anxiety and distress fed by constant exposure to the Internet and social media. This can—and should—be done through multiple venues: religious and social groups and the workplace.
7. Inform the public with PowerPoint presentations and seminars, advertising what to look for and where to get help for concerning behaviors; again, this can be done through multiple portals. This, I believe, may also help defuse tensions between parents and schools surrounding children with health and educational differences.
8. Have professional health associations deliver a cohesive message to our legislators for gun control, funding for research, and mental and public health.

Dr. Onieal, you are correct in saying that this epidemic of mass shootings is a public health issue. It is a threat as serious as HIV, cancer, lead poisoning, hypertension, and diabetes. We must find a way to stop this epidemic.

Dr. Onieal, you are correct in saying that this epidemic of mass shootings is a public health issue. It is a threat as serious as HIV, cancer, lead poisoning, hypertension, and diabetes. We must find a way to stop this epidemic.

Opioid use has not significantly declined over the past 10 years despite efforts to educate prescribers about the risks of opioid abuse, with over half of disabled Medicare beneficiaries using opioids each year, according to a recent retrospective cohort study published in the BMJ.

“We found very high prevalence of opioid use and opioid doses in disabled Medicare beneficiaries, most likely reflecting the high burden of illness in this population,” Molly M. Jeffery, PhD, from the Mayo Clinic, Rochester, Minn., and her associates wrote in their study.

The investigators evaluated pharmaceutical and medical claims data from 48 million individuals who were commercially insured or were Medicare Advantage recipients (both those eligible because they were older than 65 years and those under 65 years old who still were eligible because of disability). The researchers found that 52% of disabled Medicare patients, 26% of aged Medicare patients, and 14% of commercially insured patients used opioids annually within the study period.

In the commercially insured group, there was little fluctuation in patient opioid prevalence by quarter, with an average daily dose of 17 mg morphine equivalents (MME) during 2011-2016; 6% of patients used opioids quarterly at the beginning and end of the study. There was an increase of quarterly opioid prevalence in the aged Medicare group from 11% to 14% at the beginning and end of the study period. Average daily dose also increased during this period for the aged Medicare group from 18 MME in 2011 to 20 MME in 2016.

Researchers said commercial beneficiaries between 45 years and 54 years old had the highest prevalence of opioid use. The disabled Medicare group saw the greatest increase among groups in opioid prevalence and average daily dose, with a 26% prevalence in 2007 and 53 MME average daily dose, which increased to a prevalence of 39% and an average daily dose of 56 MME in 2016.

“Doctors and patients should consider whether long-term opioid use is improving the patient’s ability to function and, if not, should consider other treatments either as an addition or replacement to opioid use,” Dr. Jeffery and her colleagues wrote. “Evidence-based approaches are needed to improve both the safety of opioid use and patient outcomes including pain management and ability to function.”

The researchers noted limitations in the study, such as not including people with Medicaid, fee-for-service Medicare, or the uninsured. In addition, the data reviewed did not indicate the prevalence of chronic pain or pain duration in the patient population studied, they said.

The authors reported no relevant financial disclosures.

Rationale  
For patients who have small varices with either red wale signs or the presence of severe liver disease (Child Pugh class C), the risk of first hemorrhage is as high as for patients with large varices. Because these small varices are difficult to ligate, therapy with a nonselective beta-blocker such as nadolol is recommended. Nonselective beta-adrenergic blockers (propranolol, nadolol) reduce portal pressure by reducing portal venous inflow through both a beta-1 (reduction in cardiac output) and a beta-2 (splanchnic vasoconstriction). A decrease in HVPG greater than 20% in patients treated with nonselective beta-blockers has been associated with a lower rate of first variceal hemorrhage, ascites, and death. Clinical targets include a heart rate below 60 bpm or a 25% reduction from baseline heart rate. Metoprolol is a selective beta-blocker and is not effective in reducing portal pressure. Nitrates alone are not effective in preventing first variceal hemorrhage and are associated with increased long-term mortality in patients over the age of 50. Diltiazem is a calcium channel blocker, which has not been shown to be effective in the treatment of esophageal varices. Observation is not an appropriate option given the high risk of bleeding for these varices, which should be addressed.

Editor's Note: 

As quality metrics are becoming increasingly significant throughout all of medicine, our field is no exception. Recent evidence has demonstrated the importance of quality measures in colonoscopy; understanding, reporting, and improving these metrics has become a hot topic of discussion.

In this month’s In Focus article, brought to you by The New Gastroenterologist, Nabiha Shamsi, Ashish Malhotra, and Aasma Shaukat (University of Minnesota/Minneapolis VAMC) provide an outstanding overview of the evidence as well as recommended goals for important quality metrics in colonoscopy. Ultimately, improving colonoscopy quality amongst all gastroenterologists will increase colonoscopy value and lead to further decreases in the incidence and mortality of colorectal cancer.

Introduction

Colonoscopy is a widely used modality to evaluate colorectal cancer because it allows for both identification of early malignancies and removal of precancerous lesions. The increased use of colonoscopy in the last 20 years has been associated with a decline in the incidence and mortality from colorectal cancer.^1,2 However, colonoscopy has its limitations. It is an invasive test with inherent risks. Additionally, studies have reported rates of post-colonoscopy cancers, also referred to as interval cancers, of 2%-7%, and miss-rates for adenomas by tandem colonoscopy of 2%-26%.^3-5

High-quality exams can maximize the value of colonoscopy, and it is important to consider the factors that contribute to high-quality colonoscopies. While there are many metrics proposed,^6,7 here we discuss the most evidence-based ones, outlined in Table 1, along with their goal values.
 

Cecal intubation rate

A high-quality colonoscopy should include a complete examination of the colon. To achieve this, it is necessary to fully intubate the cecum, passing the colonoscope past the ileocecal valve to examine the medial wall of the cecum.⁸

There are several factors that may contribute to an incomplete colonoscopy, including bowel preparation, anatomy, body habitus, and endoscopist’s skill. To calculate cecal intubation rate as a quality measure, colonoscopies that are incomplete because of poor bowel preparation, severe colitis, or known obstructing lesion are usually excluded.

The U.S. Multi-Society Task Force on Colorectal Cancer recommends a cecal intubation rate of at least 95% for screening colonoscopy and 90% for all colonoscopies.⁶ There is an expectation of photodocumentation of the ileocecal valve and appendiceal orifice to establish completion of the colonoscopy.⁶

Some methods used to assist with cecal intubation include changing patient position, applying abdominal pressure, stiffening the colonoscope, and alternating between adult or pediatric colonoscopes.
 

Adenoma detection rate

Adenoma detection rate (ADR), is defined as the proportion of patients over the age of 50 years undergoing first-time screening colonoscopies in which at least one adenomatous polyp is detected for a given endoscopist in a given time period.

Adenomas are tracked because clearing the colon of neoplasm is the goal of screening colonoscopies; adenomas are tracked instead of more advanced lesions because the higher frequency of adenomas allows for better tracking of variation between endoscopists. Tracking ADR also utilizes the assumption that, if small lesions are identified, larger ones will be as well.

ADR is the only current quality indicator reported to be significantly associated with the risk of interval cancers. In 2010, a study of 45,000 screening colonoscopies by 186 endoscopists validated the use of ADR, finding that patients who underwent colonoscopy by physicians with ADRs below 20% had hazard ratios for development of postcolonoscopy cancer greater than 10 times higher than patients of physicians with ADRs above 20%.⁹ However, this study had limited power to establish that cancer protection continues to improve when ADRs rise above 20%. Another study, which evaluated the association of ADR in 224,000 patients undergoing colonoscopies by 136 gastroenterologists, showed each 1% increase in ADR is associated with 3% decrease in the risk of interval CRC and 5% decrease in the risk of fatal interval cancers.¹⁰

Most recent guidelines propose an adequate ADR for asymptomatic individuals aged 50 years or older undergoing screening colonoscopy should be greater than 30% in men and greater than 20% in women.⁶ It remains unknown whether there is a threshold for maximum benefit of ADR, in which a very high ADR is not associated with further protective benefit. The answer to this question may depend on why a low ADR is associated with a higher rate of interval cancers and whether every missed polyp, independent of size, is a potential interval cancer or whether hasty, inadequate, or incomplete examinations of the colon are the underlying concern.

Withdrawal time

Optimizing identification of colonic lesions requires a careful and thorough exam of the colon on withdrawal. While this may seem obvious, there is often little focus on the approach to withdrawal. In four chapters on colonoscopy technique from textbooks, the number of pages describing insertion ranged from 20 to 38, while the number of pages focused on withdrawal ranged from 0.5 to 1.5.^11-14

A study examining the difference in withdrawal technique between two endoscopists who were known to differ in adenoma miss rates by tandem colonoscopy proposed the scoring system listed in Table 2 that can assess quality of examination on withdrawal. There was a statistically significant difference in quality scores for the two endoscopists, as assessed by expert review of video recordings of their colonoscopies.¹⁵

The endoscopist with the lower adenoma miss rate was also found to have an average withdrawal time of 8 minutes and 55 seconds versus 6 minutes and 41 seconds for the endoscopist with the higher adenoma miss rate. A large, community-based study with over 76,000 colonoscopies found a statistically significant correlation between interval colorectal cancer and withdrawal times shorter than 6 minutes.¹⁶ However, there was no association between ADR and colorectal cancer, suggesting that, for practices with optimal ADRs (that is, rates greater than 25%), withdrawal time may be a more sensitive marker of quality of colonoscopy than ADR is.¹⁶Intuitively, adequate examination of the colon that includes examining the proximal side of folds, washing and suctioning stool, and even repositioning the patient would likely increase withdrawal time. In a 2008 study examining 2,000 screening colonoscopies of 12 endoscopists, those with withdrawal times greater than 6 minutes had significantly higher rates of detecting adenomas and advanced neoplasia, compared with those with faster withdrawal times.¹⁷ The average ADR in this group was 28.3%, compared with 11.8% for physicians who had a withdrawal time less than 6 minutes.¹⁷ An evaluation of nearly 11,000 colonoscopies done by 43 endoscopists also identified an increase polyp yield with increased withdrawal time.¹⁸ These data drive the recommendation for a minimum withdrawal time of 6 minutes, with 2 minutes spent examining each colonic segment.

Bowel preparation

Diagnosis of colonic lesions is dependent on adequate visualization of the colon. Poor bowel preparation can limit the yield of colonoscopy and lead to missed lesions. It also leads to canceled and rescheduled procedures that reduce efficiency, increase cost, and pose an undue burden on the patient.

The quality of bowel preparation should be assessed after washing and suctioning of colonic mucosa has been completed. Adequate preparation is that which allows identification of lesions greater than 5 mm in size.¹⁹

Quality of preparation is assessed subjectively by the endoscopists and often listed as excellent, good, fair, or poor. An alternative method of reporting bowel preparation quality is the Boston Bowel Preparation Score (BBPS) (Table 3).²⁰ This scoring system allows for a more descriptive assessment of each colonic segment by assigning a score from 0 to 3 for the right, transverse, and left colon, leading to a total score between 0 and 9. The BBPS also helps standardize reporting of bowel preparation. The polyp detection rate associated with a BBPS of 5 or greater was 40%, compared with 24% associated with BBPS less than 5.¹⁹ A split-dose bowel preparation regimen with at least half of the preparation ingested on the day of the procedure is recommended to optimize quality of bowel preparation.⁶

The American Society for Gastrointestinal Endoscopy and American College of Gastroenterology task force on quality assurance in endoscopy recommends that bowel preparation should be adequate in 85% of all colonoscopy exams on a per-provider basis.⁷ One study of completed colonoscopy with inadequate preparation showed an adenoma miss rate of 48%.²¹ In the setting of inadequate bowel preparation, another study reported 42% of all adenomas detected were only found on repeat colonoscopy. When considering advanced adenomas, there was a 27% miss rate, a relatively high percentage.²²
 

When poor bowel preparation precludes the exam, colonoscopy is appropriately aborted, and the patient asked to return. However, there are situations in which the exam can be completed but the bowel preparation is still inadequate to identify polyps larger than 5 mm. In this setting, the colonoscopy should be repeated with a more aggressive bowel preparation regimen within 1 year.¹⁹ Shorter intervals are recommended if advanced neoplasm is detected within an inadequate bowel preparation.¹⁹

The appropriate surveillance interval can be unclear when bowel preparation is considered adequate to identify polyps greater than or equal to 5 mm, yet still suboptimal. “Adequate” or “fair” bowel preparation often leads to shorter-than-recommended surveillance intervals because of the concern for small missed lesions. For example, patients with normal colonoscopy results and a fair prep were recommended to undergo a screening colonoscopy in 5 years at 57.4%, while only 23.1% received a 10-year recommendation.²³ This increased frequency of colonoscopy leads to increased costs and procedural risks for the patient. Furthermore, a meta-analysis evaluating the effects of bowel preparation reported no significant difference in ADR between adequate and excellent prep.²⁴ These findings suggest that patients with adequate bowel preparation may be followed at guideline-recommended surveillance intervals without significantly affecting colonoscopy quality as measured by ADR.

Endoscopist feedback and report cards

Awareness of quality metrics among individuals and endoscopy practices is crucial to ensuring adequate performance. Several studies have shown improvement with feedback and monitoring of endoscopists.^25,26 Some strategies to improve colonoscopy technique and efficiency include having recorded or observed procedures, computer software that measures image resolution/velocity, and scorecards with quality measures. A representation of the scorecards used in our practice is shown in Table 4. Feedback measures both make endoscopists aware of how their performance compares with recommended goals for colonoscopy and help track their improvement. We recommend such feedback should be provided quarterly for most providers and more frequently for providers not meeting benchmarks.

Conclusion

Given we rely on colonoscopy to identify and clear the colon of potential malignancy, it is imperative that we provide high-value exams for our patients. The basis for a quality colonoscopy is complete intubation and careful inspection of the mucosa on withdrawal. Several quality measures are used as surrogates of a good exam such that endoscopists can assess themselves in relation to their peers. These metrics can help us in our goal of remaining mindful during each procedure we are completing and providing the best exam possible.

In 2010, a study of 45,000 screening colonoscopies by 186 endoscopists validated the use of ADR, finding that patients who underwent colonoscopy by physicians with ADRs below 20% had hazard ratios for development of postcolonoscopy cancer greater than 10 times higher than patients of physicians with ADRs above 20%.⁹ However, this study had limited power to establish that cancer protection continues to improve when ADRs rise above 20%. Another study, which evaluated the association of ADR in 224,000 patients undergoing colonoscopies by 136 gastroenterologists, showed each 1% increase in ADR is associated with 3% decrease in the risk of interval CRC and 5% decrease in the risk of fatal interval cancers.¹⁰

Most recent guidelines propose an adequate ADR for asymptomatic individuals aged 50 years or older undergoing screening colonoscopy should be greater than 30% in men and greater than 20% in women.⁶ It remains unknown whether there is a threshold for maximum benefit of ADR, in which a very high ADR is not associated with further protective benefit. The answer to this question may depend on why a low ADR is associated with a higher rate of interval cancers and whether every missed polyp, independent of size, is a potential interval cancer or whether hasty, inadequate, or incomplete examinations of the colon are the underlying concern.

Withdrawal time

Optimizing identification of colonic lesions requires a careful and thorough exam of the colon on withdrawal. While this may seem obvious, there is often little focus on the approach to withdrawal. In four chapters on colonoscopy technique from textbooks, the number of pages describing insertion ranged from 20 to 38, while the number of pages focused on withdrawal ranged from 0.5 to 1.5.^11-14

A study examining the difference in withdrawal technique between two endoscopists who were known to differ in adenoma miss rates by tandem colonoscopy proposed the scoring system listed in Table 2 that can assess quality of examination on withdrawal. There was a statistically significant difference in quality scores for the two endoscopists, as assessed by expert review of video recordings of their colonoscopies.¹⁵

The endoscopist with the lower adenoma miss rate was also found to have an average withdrawal time of 8 minutes and 55 seconds versus 6 minutes and 41 seconds for the endoscopist with the higher adenoma miss rate. A large, community-based study with over 76,000 colonoscopies found a statistically significant correlation between interval colorectal cancer and withdrawal times shorter than 6 minutes.¹⁶ However, there was no association between ADR and colorectal cancer, suggesting that, for practices with optimal ADRs (that is, rates greater than 25%), withdrawal time may be a more sensitive marker of quality of colonoscopy than ADR is.¹⁶Intuitively, adequate examination of the colon that includes examining the proximal side of folds, washing and suctioning stool, and even repositioning the patient would likely increase withdrawal time. In a 2008 study examining 2,000 screening colonoscopies of 12 endoscopists, those with withdrawal times greater than 6 minutes had significantly higher rates of detecting adenomas and advanced neoplasia, compared with those with faster withdrawal times.¹⁷ The average ADR in this group was 28.3%, compared with 11.8% for physicians who had a withdrawal time less than 6 minutes.¹⁷ An evaluation of nearly 11,000 colonoscopies done by 43 endoscopists also identified an increase polyp yield with increased withdrawal time.¹⁸ These data drive the recommendation for a minimum withdrawal time of 6 minutes, with 2 minutes spent examining each colonic segment.

Bowel preparation

Diagnosis of colonic lesions is dependent on adequate visualization of the colon. Poor bowel preparation can limit the yield of colonoscopy and lead to missed lesions. It also leads to canceled and rescheduled procedures that reduce efficiency, increase cost, and pose an undue burden on the patient.

The quality of bowel preparation should be assessed after washing and suctioning of colonic mucosa has been completed. Adequate preparation is that which allows identification of lesions greater than 5 mm in size.¹⁹

Quality of preparation is assessed subjectively by the endoscopists and often listed as excellent, good, fair, or poor. An alternative method of reporting bowel preparation quality is the Boston Bowel Preparation Score (BBPS) (Table 3).²⁰ This scoring system allows for a more descriptive assessment of each colonic segment by assigning a score from 0 to 3 for the right, transverse, and left colon, leading to a total score between 0 and 9. The BBPS also helps standardize reporting of bowel preparation. The polyp detection rate associated with a BBPS of 5 or greater was 40%, compared with 24% associated with BBPS less than 5.¹⁹ A split-dose bowel preparation regimen with at least half of the preparation ingested on the day of the procedure is recommended to optimize quality of bowel preparation.⁶

The American Society for Gastrointestinal Endoscopy and American College of Gastroenterology task force on quality assurance in endoscopy recommends that bowel preparation should be adequate in 85% of all colonoscopy exams on a per-provider basis.⁷ One study of completed colonoscopy with inadequate preparation showed an adenoma miss rate of 48%.²¹ In the setting of inadequate bowel preparation, another study reported 42% of all adenomas detected were only found on repeat colonoscopy. When considering advanced adenomas, there was a 27% miss rate, a relatively high percentage.²²
 

When poor bowel preparation precludes the exam, colonoscopy is appropriately aborted, and the patient asked to return. However, there are situations in which the exam can be completed but the bowel preparation is still inadequate to identify polyps larger than 5 mm. In this setting, the colonoscopy should be repeated with a more aggressive bowel preparation regimen within 1 year.¹⁹ Shorter intervals are recommended if advanced neoplasm is detected within an inadequate bowel preparation.¹⁹

The appropriate surveillance interval can be unclear when bowel preparation is considered adequate to identify polyps greater than or equal to 5 mm, yet still suboptimal. “Adequate” or “fair” bowel preparation often leads to shorter-than-recommended surveillance intervals because of the concern for small missed lesions. For example, patients with normal colonoscopy results and a fair prep were recommended to undergo a screening colonoscopy in 5 years at 57.4%, while only 23.1% received a 10-year recommendation.²³ This increased frequency of colonoscopy leads to increased costs and procedural risks for the patient. Furthermore, a meta-analysis evaluating the effects of bowel preparation reported no significant difference in ADR between adequate and excellent prep.²⁴ These findings suggest that patients with adequate bowel preparation may be followed at guideline-recommended surveillance intervals without significantly affecting colonoscopy quality as measured by ADR.

Endoscopist feedback and report cards

Awareness of quality metrics among individuals and endoscopy practices is crucial to ensuring adequate performance. Several studies have shown improvement with feedback and monitoring of endoscopists.^25,26 Some strategies to improve colonoscopy technique and efficiency include having recorded or observed procedures, computer software that measures image resolution/velocity, and scorecards with quality measures. A representation of the scorecards used in our practice is shown in Table 4. Feedback measures both make endoscopists aware of how their performance compares with recommended goals for colonoscopy and help track their improvement. We recommend such feedback should be provided quarterly for most providers and more frequently for providers not meeting benchmarks.

Conclusion

Given we rely on colonoscopy to identify and clear the colon of potential malignancy, it is imperative that we provide high-value exams for our patients. The basis for a quality colonoscopy is complete intubation and careful inspection of the mucosa on withdrawal. Several quality measures are used as surrogates of a good exam such that endoscopists can assess themselves in relation to their peers. These metrics can help us in our goal of remaining mindful during each procedure we are completing and providing the best exam possible.

Editor's Note: 

As quality metrics are becoming increasingly significant throughout all of medicine, our field is no exception. Recent evidence has demonstrated the importance of quality measures in colonoscopy; understanding, reporting, and improving these metrics has become a hot topic of discussion.

In this month’s In Focus article, brought to you by The New Gastroenterologist, Nabiha Shamsi, Ashish Malhotra, and Aasma Shaukat (University of Minnesota/Minneapolis VAMC) provide an outstanding overview of the evidence as well as recommended goals for important quality metrics in colonoscopy. Ultimately, improving colonoscopy quality amongst all gastroenterologists will increase colonoscopy value and lead to further decreases in the incidence and mortality of colorectal cancer.

Introduction

Colonoscopy is a widely used modality to evaluate colorectal cancer because it allows for both identification of early malignancies and removal of precancerous lesions. The increased use of colonoscopy in the last 20 years has been associated with a decline in the incidence and mortality from colorectal cancer.^1,2 However, colonoscopy has its limitations. It is an invasive test with inherent risks. Additionally, studies have reported rates of post-colonoscopy cancers, also referred to as interval cancers, of 2%-7%, and miss-rates for adenomas by tandem colonoscopy of 2%-26%.^3-5

High-quality exams can maximize the value of colonoscopy, and it is important to consider the factors that contribute to high-quality colonoscopies. While there are many metrics proposed,^6,7 here we discuss the most evidence-based ones, outlined in Table 1, along with their goal values.
 

Cecal intubation rate

A high-quality colonoscopy should include a complete examination of the colon. To achieve this, it is necessary to fully intubate the cecum, passing the colonoscope past the ileocecal valve to examine the medial wall of the cecum.⁸

There are several factors that may contribute to an incomplete colonoscopy, including bowel preparation, anatomy, body habitus, and endoscopist’s skill. To calculate cecal intubation rate as a quality measure, colonoscopies that are incomplete because of poor bowel preparation, severe colitis, or known obstructing lesion are usually excluded.

The U.S. Multi-Society Task Force on Colorectal Cancer recommends a cecal intubation rate of at least 95% for screening colonoscopy and 90% for all colonoscopies.⁶ There is an expectation of photodocumentation of the ileocecal valve and appendiceal orifice to establish completion of the colonoscopy.⁶

Some methods used to assist with cecal intubation include changing patient position, applying abdominal pressure, stiffening the colonoscope, and alternating between adult or pediatric colonoscopes.
 

Adenoma detection rate

Adenoma detection rate (ADR), is defined as the proportion of patients over the age of 50 years undergoing first-time screening colonoscopies in which at least one adenomatous polyp is detected for a given endoscopist in a given time period.

Adenomas are tracked because clearing the colon of neoplasm is the goal of screening colonoscopies; adenomas are tracked instead of more advanced lesions because the higher frequency of adenomas allows for better tracking of variation between endoscopists. Tracking ADR also utilizes the assumption that, if small lesions are identified, larger ones will be as well.

ADR is the only current quality indicator reported to be significantly associated with the risk of interval cancers. In 2010, a study of 45,000 screening colonoscopies by 186 endoscopists validated the use of ADR, finding that patients who underwent colonoscopy by physicians with ADRs below 20% had hazard ratios for development of postcolonoscopy cancer greater than 10 times higher than patients of physicians with ADRs above 20%.⁹ However, this study had limited power to establish that cancer protection continues to improve when ADRs rise above 20%. Another study, which evaluated the association of ADR in 224,000 patients undergoing colonoscopies by 136 gastroenterologists, showed each 1% increase in ADR is associated with 3% decrease in the risk of interval CRC and 5% decrease in the risk of fatal interval cancers.¹⁰

Most recent guidelines propose an adequate ADR for asymptomatic individuals aged 50 years or older undergoing screening colonoscopy should be greater than 30% in men and greater than 20% in women.⁶ It remains unknown whether there is a threshold for maximum benefit of ADR, in which a very high ADR is not associated with further protective benefit. The answer to this question may depend on why a low ADR is associated with a higher rate of interval cancers and whether every missed polyp, independent of size, is a potential interval cancer or whether hasty, inadequate, or incomplete examinations of the colon are the underlying concern.
