Consortium to undertake longitudinal study of acquired TTP
Image by Erhabor Osaro
SAN DIEGO—The US Thrombotic Microangiopathies (USTMA) Consortium is planning a longitudinal study to identify biomarkers of relapse and neurocognitive dysfunction in acquired thrombotic thrombocytopenic purpura (TTP).
Earlier studies suggested that ADAMTS13 activity during remission has
limited utility in estimating relapse risk, and cognitive dysfunction
observed in TTP appears to be progressive and independent of relapses.
However, these studies were small with minimal longitudinal data.
Now, the USTMA Consortium, with 13 large referral centers for thrombotic microangiopathies (TMAs) in the US, is providing “the infrastructure for larger US studies in TTP with the goal of improving outcomes in TMAs,” said Marshall A. Mazepa, MD, of the University of Minnesota in Minneapolis.
He described the efforts of the consortium and its plans to conduct a long-term study at the first TTP-TMA Workshop, which took place immediately before the 2016 ASH Annual Meeting.
Dr Mazepa said the objective of the study is to identify biomarkers that
predict the danger period for neurocognitive dysfunction and relapse.
“Hematologists usually do not realize the
neurocognitive dysfunction among patients with TTP, and it is important
that they [hematologists] talk to neurologists,” said Spero Cataland, MD, an organizer of the TTP-TMA Workshop from The Ohio State University in
Columbus.
“This study will be crucial in
improving our understanding of this issue.”
The consortium plans to study 100 TTP patients in remission for 3 years.
Every
3 months, patients will complete neuropsychologic testing, and
investigators will evaluate patients’ end-organ ischemic biomarkers,
ADAMTS13 activity, ultra-large von Willebrand factor levels, and
complement activation biomarkers.
In addition to this study, the USTMA Consortium is participating in the phase 3 HERCULES study of caplacizumab for acquired TTP.
Caplacizumab, which is being developed by Ablynx, was previously evaluated for acquired TTP in the phase 2 TITAN study.
The phase 3 study is a double-blind, placebo-controlled trial designed to determine whether neurocognitive function can be preserved with caplacizumab intervention.
Investigators intend to enroll 92 patients at clinical sites in 17 countries. Recruitment is expected to be complete by the end of 2017.
In closing, Dr Mazepa invited interested clinicians to join the USTMA Consortium by contacting him ([email protected]) or Dr Cataland ([email protected]).

Iron deficiency anemia protects kids from malaria better than sickle cell trait

New research suggests that, for young children, iron deficiency anemia offers a
greater protective effect against malaria than sickle cell trait.
The
study indicates that iron deficiency anemia can protect children age 2 and
younger from the blood stage of Plasmodium falciparum malaria, and
treating the anemia with iron supplementation removes this protective
effect.
The researchers reported these findings in EBioMedicine.
“This study is elegant in its simplicity yet remains one of the most
substantial and systematic attempts to unveil the cellular-level
relationship between anemia, iron supplementation, and malaria risk,”
said study author Carla Cerami, MD, PhD, of the Medical Research Council
Unit The Gambia in Banjul, Gambia.
For this study, she and her colleagues analyzed the red blood cells of 135 anemic children who were participating in an iron supplementation trial.
The children ranged in age from 6 months to 24 months and lived in a malaria-endemic region of The Gambia where sickle cell trait was also common.
The children received iron (12 mg/day) through micronutrient powder for 84 days, and the researchers analyzed the children’s red blood cells at baseline, day 49, and day 84.
The team conducted in vitro growth and invasion assays with P falciparum laboratory and field strains. The study’s primary endpoint was in vitro parasite growth in the children’s RBCs.
The researchers found that “anemia substantially reduced the invasion and growth of both laboratory and field strains of P falciparum.” The team noted a roughly 10% growth reduction per standard deviation shift in hemoglobin.
On a population-wide basis, anemia reduced the blood stage of malaria by 15.9%, while the sickle cell trait reduced it by 3.5%.
“Our finding that anemia offers greater natural protection against blood-stage malaria infection than sickle cell trait has led us to formulate the interesting hypothesis that the widespread prevalence of anemia in people of African descent is a genetic signature of malaria,” said study author Morgan Goheen, PhD, of University of North Carolina in Chapel Hill.
The researchers also found that deficits in invasion and growth for blood-stage P falciparum were reversed when anemic children had received 7 weeks of iron supplementation. Parasite growth was 2.4-fold higher after supplementation than it was at baseline (P<0.001).
Prior work by the same research group suggested the increased invasion and growth rates following iron supplementation are caused by the parasites’ strong preference for young red blood cells.
The researchers said these new field results consolidate the evidence that iron supplementation increases the risk of P falciparum malaria and provide support for the use of malaria prophylaxis in
conjunction with iron supplementation, especially during the early
phases of erythroid recovery.

Hemophilia A drug approved in Europe
The European Commission has granted marketing authorization for lonoctocog alfa (Afstyla), a recombinant factor VIII (FVIII) single-chain therapy.
Lonoctocog alfa is indicated for the treatment and prophylaxis of bleeding in hemophilia A patients of all ages.
Lonoctocog alfa is the first and only single-chain recombinant FVIII therapy for hemophilia A specifically designed to provide long-lasting protection from bleeds with 2- to 3-times weekly dosing, according to CSL Behring, the company developing the product.
The company says lonoctocog alfa uses a covalent bond that forms one structural entity—a single polypeptide chain—to improve the stability of FVIII and provide FVIII activity with the option of twice-weekly dosing.
According to CSL Behring, lonoctocog alfa will be launched in European markets in the coming months, as market access is obtained.
Lonoctocog alfa is also approved for use in the US and Canada.
Regulatory submissions for lonoctocog alfa are based on results from the AFFINITY clinical development program, which includes a trial of children (n=84) and a trial of adolescents and adults (n=175).
Among patients who received lonoctocog alfa prophylactically in these trials, the median annualized bleeding rate was 1.14 in the adults/adolescents and 3.69 in children younger than 12.
In all, there were 1195 bleeding events—848 in the adults/adolescents and 347 in the children.
Ninety-four percent of bleeds in adults/adolescents and 96% of bleeds in pediatric patients were effectively controlled with no more than 2 infusions of lonoctocog alfa weekly.
Eighty-one percent of bleeds in adults/adolescents and 86% of bleeds in pediatric patients were controlled by a single infusion.
Researchers assessed safety in 258 patients from both studies. Adverse reactions occurred in 14 patients and included hypersensitivity (n=4), dizziness (n=2), paresthesia (n=1), rash (n=1), erythema (n=1), pruritus (n=1), pyrexia (n=1), injection-site pain (n=1), chills (n=1), and feeling hot (n=1).
One patient withdrew from treatment due to hypersensitivity.
None of the patients developed neutralizing antibodies to FVIII or antibodies to host cell proteins. There were no reports of anaphylaxis or thrombosis.
Results from the trial of adolescents/adults were published in Blood in August 2016. Results from the trial of children were presented at the World Federation of Hemophilia 2016 World Congress in July 2016.*

Kidney Disease Progression: How to Attenuate Risk
Q)I overheard a conversation at the hospital in which one of the nephrologists told an internist that allopurinol is better than other medications for treating gout because it slows the progression of chronic kidney disease (CKD). What does the data say?
CKD is a growing problem in America; the number of adults with CKD doubled from 2000 to 2008.1 Gout is considered an independent risk factor for CKD progression.2 Some randomized contr
A recent large retrospective review of Medicare charts assessed the correlation between use and dose of allopurinol and incidence of renal failure in patients older than 65.1 The researchers found that, compared with lower doses, allopurinol doses of 200 to 299 mg/d and > 300 mg/d were associated with a significantly lower hazard ratio for kidney failure, in a multivariate-adjusted model. The findings therefore suggest that doses > 199 mg may slow progression to kidney failure in the elderly.
Despite the strengths of this study, it is worth noting that it did not consider stage of kidney disease, nor did it distinguish comorbidities of the patients. The retrospective chart review format did not allow for identification of concurrent medication use (including OTC and herbal products).
The National Institute of Diabetes and Digestive and Kidney Diseases is currently conducting an RCT to investigate the renoprotective effects of allopurinol versus placebo in diabetic patients. (Clinical Trials.gov identifier: NCT02017171). Enrollment was completed in 2014, and results are expected in June 2019.
One important proviso about allopurinol: While it is inexpensive and generally well tolerated, prescribers should be aware of rare sensitivity reactions, particularly Stevens-Johnson syndrome. —MRS

Longer follow-up needed to track mesh explantation trends
Explantation of mesh used in ventral hernia repair occurs in approximately 1 of every 1,000 surgeries, but it’s a “hidden” morbidity because it almost always happens well after the 30- to 90-day window in which postoperative complications are typically reported in most registries and surveillance systems, according to a report in the Journal of the American College of Surgeons.
Mesh explantation usually occurs 1-3 years after implantation and triples the operative costs of the original ventral hernia repair. The rate of 1 per 1,000 surgeries and the massive increase in cost are comparable with those of occult injury of the common bile duct during cholecystectomy that later requires biliary reconstruction. But mesh explantation doesn’t generate the “profound attention” accorded to bile duct injury, perhaps because it develops much later in the postoperative course.
“It is surprising that mesh complications have not yet prompted similar concern,” said Kristy Kummerow Broman, MD, of the department of surgery, Vanderbilt University Medical Center, Nashville, Tenn., and her associates.
Until now, the frequency and cost of mesh explantation after ventral hernia repair in the general population have not been known. To make a reasonable estimate, the investigators constructed a cohort of 619,751 patients using information from inpatient and surgery databases for New York, California, and Florida between 2005 and 2011. Most of these were open procedures (91%), while 9% were laparoscopic.
During a mean follow-up of 3 years, 438 patients (0.7 per 1,000) underwent mesh explantation. This is a clinically significant incidence, and is likely an underestimate because ICD-9 and CPT coding for mesh removal is highly variable, Dr. Broman and her associates said.
This rate, for just three states during 3 years of follow-up, is nearly twice as high as the rate of mesh-related complications voluntarily reported to the FDA in post-marketing surveillance for the entire country during a 7-year period, they noted (J Am Coll Surg. 2017 Jan;224:35-42).
“It is paramount” that surgeons, manufacturers, and regulatory groups advocate mandatory reporting and “extend the surveillance for at least 1-3 years after implantation of a mesh device,” Dr. Broman and her associates said.
In this study, the median time to explantation was approximately 1 year (range, 2 days to 6 years), and 80% of explantations occurred within 2 years.
The median cumulative operative cost – excluding physician fees, nonsurgical medical costs, and the costs of patient disability and lost productivity – were $21,889 for patients requiring mesh explantation, compared with only $6,579 for those who did not. This finding highlights “the profound long-term implications of implantable devices in abdominal wall reconstruction,” they noted.
To put their findings in context, the investigators reviewed the literature regarding major bile duct injury during cholecystectomy. One large study on cases from 2001 to 2011 found that the rate of biliary reconstruction was comparable with that of explantation, at 0.8 to 1.1 per 1,000. Similarly, reoperation for bile duct injury approximately tripled the operative costs ($9,061 for patients who required biliary reconstruction vs $2,689 for those who didn’t). However, the $21,000 for mesh reoperation far exceeds the $9,000 for biliary reoperation.

Dr. Broman reported having no relevant financial disclosures; her associates reported ties to Intuitive Surgical Solutions, Bard Davol, Ariste Medical, and Pfizer.
Explantation of mesh used in ventral hernia repair occurs in approximately 1 of every 1,000 surgeries, but it’s a “hidden” morbidity because it almost always happens well after the 30- to 90-day window in which postoperative complications are typically reported in most registries and surveillance systems, according to a report in the Journal of the American College of Surgeons.
Mesh explantation usually occurs 1-3 years after implantation and triples the operative costs of the original ventral hernia repair. The rate of 1 per 1,000 surgeries and the massive increase in cost are comparable with those of occult injury of the common bile duct during cholecystectomy that later requires biliary reconstruction. But mesh explantation doesn’t generate the “profound attention” accorded to bile duct injury, perhaps because it develops much later in the postoperative course.
“It is surprising that mesh complications have not yet prompted similar concern,” said Kristy Kummerow Broman, MD, of the department of surgery, Vanderbilt University Medical Center, Nashville, Tenn., and her associates.
Until now, the frequency and cost of mesh explantation after ventral hernia repair in the general population have not been known. To make a reasonable estimate, the investigators constructed a cohort of 619,751 patients using information from inpatient and surgery databases for New York, California, and Florida between 2005 and 2011. Most of these were open procedures (91%), while 9% were laparoscopic.
During a mean follow-up of 3 years, 438 patients (0.7 per 1,000) underwent mesh explantation. This is a clinically significant incidence, and is likely an underestimate because ICD-9 and CPT coding for mesh removal is highly variable, Dr. Broman and her associates said.
This rate, for just three states during 3 years of follow-up, is nearly twice as high as the rate of mesh-related complications voluntarily reported to the FDA in post-marketing surveillance for the entire country during a 7-year period, they noted (J Am Coll Surg. 2017 Jan;224:35-42).
“It is paramount” that surgeons, manufacturers, and regulatory groups advocate mandatory reporting and “extend the surveillance for at least 1-3 years after implantation of a mesh device,” Dr. Broman and her associates said.
In this study, the median time to explantation was approximately 1 year (range, 2 days to 6 years), and 80% of explantations occurred within 2 years.
The median cumulative operative cost – excluding physician fees, nonsurgical medical costs, and the costs of patient disability and lost productivity – were $21,889 for patients requiring mesh explantation, compared with only $6,579 for those who did not.

Lightweight mesh linked to longer LOS, worse QOL
Compared with midweight mesh, lightweight mesh was associated with more surgical site infection and longer hospital stay following open ventral hernia repair, according to a report published in the American Journal of Surgery.
In addition, lightweight mesh was associated with greater pain, more limitation of movement, and poorer quality of life for up to 2 years after the procedure, compared with midweight mesh.
Approximately 250,000 open ventral hernia repairs are performed in the Unites States each year, and mesh is used in 85% or more. Since heavyweight mesh was found to reduce abdominal wall mobility, which led to chronic discomfort in about 20% of cases, manufacturers turned to mesh that was more flexible, had reduced mass to decrease foreign-body reactions, but was strong enough to withstand the physiological stress that the abdominal wall is subjected to, the investigators noted.
They compared outcomes after hernia repairs using lightweight and midweight mesh by analyzing information in the International Hernia Mesh Registry database, which covers more than 30 medical centers in 10 countries. For this study, the researchers focused on 549 patients for whom surgeons had selected lightweight (34.2%) or midweight (47.7%) mesh. (The remaining 18.1% of cases used heavyweight mesh.)
Across the study groups, patients were similar for gender distribution; body mass index; race; and the presence of chronic obstructive pulmonary disease, asthma, and immunosuppression – factors that can heavily influence wound repair.
In an initial analysis of the data, midweight mesh was associated with significantly fewer superficial surgical site infections (1.2%) than lightweight mesh (4.8%), as well as a significantly shorter length of stay (3.6 days vs 5.3 days). However, rates of postoperative abdominal wall complications, abscesses, urinary tract infection, pneumonia, hematoma formation, seroma formation, ileus, deep vein thrombosis, and unplanned returns to the operating room were similar.
At 6-month follow-up, lightweight mesh was associated with significantly greater mesh sensation, abdominal discomfort, and movement limitation, as well as significantly worse overall quality of life (QOL), than midweight mesh. At 12 months, lightweight mesh was associated with significantly greater pain and limitation of movement and significantly worse QOL. At 24 months, lightweight mesh continued to be associated with movement limitation, but scores on other measures were similar to those with midweight mesh.
In a multivariate analysis that controlled for many potentially confounding variables, including smoking status, separation of the components of the mesh, the number of sutures anchoring the mesh, and the mesh location within the abdomen, midweight mesh was not associated with worse QOL scores at any time point. In contrast, lightweight mesh was associated with significantly worse QOL scores at 6 months, with an odds ratio of 2.64, and with significantly more pain at 12 months, with an OR of 2.58, Dr. Groene and his associates said (Am J Surg. 2016 Dec;212[6]:1054-62).
The investigators also noted that among their own hernia repair patients, lightweight mesh tends to fracture more easily than midweight mesh. Recent studies also have reported that over time, lightweight mesh is more likely to fail due to fracturing than midweight mesh, they added.
This study had no relevant financial relationships or sources of support. Dr. Groene and his associates reported having no financial conflicts of interest.

High levels of flu activity in 10 U.S. states
The 2016-2017 flu season shifted into high gear at the end of calendar year 2016, as four states were reported to be at the highest level of flu activity and six others were close behind, according to the Centers for Disease Control and Prevention.
For the week ending Dec. 31, 2016, Georgia, New Jersey, Oklahoma, and Oregon were at level 10 on the CDC’s 1-10 scale of influenza-like illness (ILI). Others in the “high” range were New York at level 9 and Alabama, Louisiana, Missouri, South Carolina, and Utah at level 8. Puerto Rico was also at level 8, after being at level 10 for the previous few weeks. An additional 10 states were in the “moderate” range (6-7), the CDC reported.
The CDC has not reported any flu-related pediatric deaths yet this season. Pediatric death totals for each of the last 3 years were 111 for 2013-2014, 148 for 2014-2015, and 89 for 2015-2016, the CDC said.

Adolescents, boys, black children most likely to be hospitalized in SJS and TEN
Annual hospitalization rates in the United States for Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) were shown to be higher in adolescents, boys, and black children, in a cross-sectional analysis of discharge records from more than 4,100 hospitals.
Using relevant ICD-9 codes, researchers at Harvard University identified 1,571 patients hospitalized for SJS, TEN, or both in 2009 and 2012, as listed in the Kids Inpatient Database from the Agency for Healthcare Research and Quality. The highest hospitalization rates per 100,000 in each year were for adolescents between 15 and 19 years (P = .01), boys (P = .03), and black children (P = .82). The overall risk of death from these conditions was 1.5% in 2009 and 0.3% in 2012. The data were published online in a brief report (Pediatr Dermatol. 2016 Dec 19. doi: 10.1111/pde.13050).
With the number of SJS- and TEN-related hospitalizations between 0.1 and 1.0 per 100,000, lead author Yusuke Okubo MD, MPH, and his colleagues wrote that their data aligned with previous studies; however, regarding the emphasis on demographic differences, theirs was, to the best of their knowledge, “the first study to reveal these disparities.” Compared with adults, they added, mortality was “remarkably lower” in children.

Instability of INRs
Clinical question: Does an initial stable international normalized ratio (INR) predict long-term stability?
Background: Warfarin decreases stroke risk among patients with atrial fibrillation; however, it interacts with food and drugs and requires monitoring to achieve a therapeutic INR. It is unclear if patients on warfarin with an initial stable INR value remain stable over time. Additionally, it is controversial whether patients on warfarin with previously stable INRs should benefit from switching to a non–vitamin K oral anticoagulant.
Study design: Retrospective study.
Setting: Outpatient clinics.
Synopsis: Data were collected from the Outcomes Registry for Better Informed Treatment of Atrial Fibrillation. Included in the study were patients taking warfarin at baseline with three or more INR values in the first 6 months and six or more INR values in the subsequent year. Stability was defined as 80% or more INRs in therapeutic range (2.0-3.0).
Only 26% of patients taking warfarin had a stable INR during the first 6 months, and only 34% continued to have a stable INR in the subsequent year.
Bottom line: Initial stable INR within the first 6 months among patients taking warfarin does not predict long-term INR stability in the subsequent year.

Partnering with stakeholders using an example patient-reported outcomes project
Recently, researchers have been challenged to design methods that ensure that key constituents are partners in research, and not simply participants. Here we describe some innovative approaches we used to engage stakeholders. The approaches are drawn from a patient-centered outcomes research project, focusing on the graphic display of patient-reported outcomes (PROs) data. PROs represent patients’ perspectives on the impact of health, disease, and treatment, without interpretation by a clinician or anyone else. PROs include, among other things, patients’ assessments of their symptoms, their level of physical and psychosocial functioning, and health-related quality-of-life.1
As a first example of the key role of stakeholders in this project, input from cancer patients and clinicians, drawn from previous research, motivated us to ask whether there might be a “better way” to display PRO data when used to inform clinical practice. Specifically, even though cancer patients and clinicians endorse the importance of PRO data to promote patient-centered care, both groups report challenges using PROs in practice because of difficulty understanding what the PRO scores mean (eg, what is a good score or a bad score?; for individual patients, which scores should clinicians be concerned about?; for clinical trial PROs, what differences in PRO scores between treatments are clinically important?). The challenges in interpreting PRO data result in part from a large number of PRO measures (eg, one database includes more than 1,000 instruments)2 and no standards across PRO measures regarding how they are scored and scaled, or in how the data are presented.3 For example, on some PRO measures, higher scores represent better outcomes; on some PRO measures, lower scores represent better outcomes; and on some PRO measures, whether higher or lower scores represent better outcomes depends on the domain being measured. Further, some measures are scaled 0-100, with the extremes representing the best/worst scores possible, whereas others are normed to, for example, a population average of 50. Because of this variation, a score of 70 can have a completely different meaning depending on the PRO measure (or domain within a measure). As noted above, previous research has documented that this variation limits patients’ and clinicians’ understanding of the PRO scores, creating an important barrier to their use in practice.4-5
To address this stakeholder-driven research question, we undertook a three-part study to identify approaches for PRO data display that can be easily interpreted, regardless of scoring or scaling conventions, with the overall goal of improving patient and clinician understanding and use of PROs in oncology clinical practice. Part 1 of the study identified attributes of graphic displays of PRO data that are helpful and confusing.6 Part 2 involved developing improved PRO data presentation approaches.7 Part 3 evaluated the accuracy-of-interpretation and clarity of the developed approaches.8-10 The methods and findings of the three-part study are reported elsewhere;6-10 here, we describe the various approaches employed to engage stakeholders throughout the project.
As described above, the first reflection of stakeholder input was in the research question we asked. We then sought to identify the key stakeholder groups and ensure that they participated in each stage of the project. The relevant stakeholder groups we identified were: patients and their caregivers; health care providers (eg, oncologists, oncology nurses) who need to understand PRO data for their own consideration and for discussion with patients; and PRO researchers who develop, validate, and apply PRO measures.
Having identified these three key stakeholder groups, we sought to obtain broad representation of their perspectives. For example, we ensured that our investigative team included a cancer survivor, a cancer care provider, and PRO researchers. To supplement the stakeholder input from the investigative team, we formed a nine-member Stakeholder Advisory Board, with multiple representatives from each key constituency. We also aimed to be as broad as possible in the populations sampled for data collection. For example, we extended beyond the Johns Hopkins cancer center to include the Johns Hopkins Clinical Research Network, a consortium of academic and community health systems across the mid-Atlantic United States. Beyond the in-person data collection across the region, our study also included an internet survey of cancer patients/survivors, cancer care providers, and PRO researchers from across the United States and internationally. Taken together, these approaches improve the diversity of our sample and, thereby, the generalizability of our findings.
In addition to obtaining broad perspectives across stakeholder groups, we created genuine partnerships with the stakeholders to inform every aspect of the project. As described above, the study itself was motivated by feedback from cancer patients and clinicians regarding the challenges they experienced when trying to interpret PRO scores, and we therefore ensured that each stakeholder group contributed to the study’s design. Stakeholders also played a critical role in the conduct of the study. For example, in the first part of the study, we conducted one-on-one interviews with 50 cancer patients and 20 cancer clinicians to obtain their insights regarding attributes of current approaches for presenting PRO data that are helpful and confusing.6 At the completion of each interview, we asked participants whether they would be interested in partnering with the researchers in developing improved presentation formats in the next phase of the project. These volunteers were organized into work groups that reviewed the findings from the initial round of interviews with the investigative team, provided suggestions regarding candidate formats that could be used to improve presentation approaches, and helped pilot the internet survey.7 In this way, research participants had the opportunity to evolve into research partners, providing critically important input throughout the process.
The implementation and dissemination of findings is another area in which stakeholder partnership is particularly valuable. For example, several of our stakeholder partners have an advocacy background, which can be quite useful for conveying the project’s results in a compelling way. Other stakeholders, such as journal editors, are in a position to act directly to implement the study findings by, for example, adding best practices for presenting PRO data to their journal’s author instructions. Notably, some of the skills stakeholders bring come in addition to their role as stakeholders. For example, one of our patient stakeholders has a background in marketing, and this marketing expertise (completely separate from his patient experience) has helped the research team think about how to present data to broad audiences in a meaningful way.
In summary, this project has implemented stakeholder-driven approaches to address an important barrier to patient-centered cancer care. Several key lessons in stakeholder engagement have emerged from this experience. It is important to identify the key constituencies early on in the process. Involving stakeholders from the start enables them to play important roles in every aspect of the study, starting with study design conception. There are also innovative ways to integrate stakeholders in study conduct, such as our work groups of research participants who volunteered to partner with the research team to develop improved data presentation approaches. Implementation and dissemination is another area where stakeholders, based on their background and connections, can play a critical role. Throughout the process, it is valuable to challenge the project to obtain perspectives from as broad a range of stakeholders as possible. Finally, stakeholders have expertise beyond their stakeholder roles, and these skills can be quite valuable to the overall research agenda. In this project, our partnership with stakeholders has helped improve the presentation of PRO data to patients and providers, thereby improving the patient-centeredness of cancer care.

Recently, researchers have been challenged to design methods that ensure that key constituents are partners in research, and not simply participants. Here we describe some innovative approaches we used to engage stakeholders. The approaches are drawn from a patient-centered outcomes research project, focusing on the graphic display of patient-reported outcomes (PROs) data. PROs represent patients’ perspectives on the impact of health, disease, and treatment, without interpretation by a clinician or anyone else. PROs include, among other things, patients’ assessments of their symptoms, their level of physical and psychosocial functioning, and health-related quality-of-life.1
As a first example of the key role of stakeholders in this project, input from cancer patients and clinicians, drawn from previous research, motivated us to ask whether there might be a “better way” to display PRO data when used to inform clinical practice.
