RESUMO

PURPOSE: Cancer treatment nonadherence is associated with higher rates of cancer recurrence and decreased survival. Rural patients with cancer experience a 10% higher mortality rate compared with their nonrural counterparts; geographic differences in nonadherence may contribute to this increased mortality. The goal of this study was to assess for geographic disparities and determine sociodemographic and clinical factors associated with radiation therapy (RT) nonadherence and survival among rural and nonrural patients with cancer. METHODS AND MATERIALS: We examined cancer registry, medical records, and billing claims data at a safety net academic medical center. Geographic residence was defined as rural versus nonrural by US Department of Agriculture 2013 Rural-Urban Continuum Codes. Other factors assessed were age, sex, race, marital status, insurance type, employment, area median household income, residential distance to cancer treatment center, clinical stage, cancer type, treatment modality, total radiation dose received, and radiation dose per fraction. We used Cox proportional hazards modeling to examine 7 ways of operationalizing nonadherence and selected the definition that resulted in the best model fit statistics and prediction of mortality. Overall survival rates were estimated with the Kaplan-Meier method. We then examined nonadherence as the main exposure along with additional covariates in least absolute shrinkage and selection operator penalized survival analyses and as the outcome in our multivariable generalized linear regression analyses predicting nonadherence. We considered 2-way interaction terms with the main exposure, geographic residence. RESULTS: We identified 3,077 patients with cancer who averaged 62 years old, were 59% female, 34% Black, and 14% rural. Twenty-two percent of patients missed at least 2 fractions and missed an average of 10% of their treatment plan. Rural patients experienced a higher mortality rate than nonrural patients (53% vs 42%, P < .0001). Survival was assessed through December 31, 2021, with a mean follow-up of 4.5 years. Proportion of missed fractions as the indicator of nonadherence provided the best model fit statistics and prediction of survival. Marital status, employment status, tumor, nodes, metastases stage, cancer type, and age at diagnosis significantly affected survival, in addition to a treatment delay by geographic residence interaction effect. Specifically, patients residing in rural areas who experienced a treatment delay were more than twice as likely to die as nonrural residents who also experienced a treatment delay, and nearly twice as likely to die as rural residents who did not experience a treatment delay. The 2-year survival rate was 76% for nonrural residents who did not experience a treatment delay versus 27% for rural residents who experienced a treatment delay. Patients who were widowed, had stage 4 cancer, or lung cancer were more likely to be nonadherent. Finally, patients residing in rural areas who experienced a treatment delay were more likely to subsequently be nonadherent. CONCLUSIONS: In a geographically and racially diverse population, RT nonadherence is a significant concern that affects survival, yet it is a modifiable risk factor. We demonstrated that rural residence was associated with both RT nonadherence and poorer overall survival. Rural patients with a treatment delay had the lowest overall survival, compared with both nonrural survivors and rural survivors without delay. Rural residents who are delayed in starting treatment are at heightened risk for poor outcomes and should receive targeted support to mitigate the observed disparities. Additional patient populations that may benefit from targeted treatment adherence support include widowed patients and those with stage 4 cancer or lung cancer.

RESUMO

INTRODUCTION: Cytomegalovirus (CMV) is one of the most common and clinically significant viral infections following allogeneic hematopoietic cell transplantation (HCT). Currently available options for CMV prophylaxis and treatment present challenges related to side effects and cost. METHODS: In this retrospective medical record review, the incidence of clinically significant CMV infection (CMV disease or reactivation requiring preemptive treatment) following allogeneic HCT was compared in patients receiving valacyclovir 1 g three times daily versus acyclovir 400 mg every 12 h for viral prophylaxis. RESULTS: Forty-five patients who received valacyclovir were matched based on propensity scoring to 35 patients who received acyclovir. All patients received reduced-intensity conditioning regimens containing anti-thymocyte globulin. Clinically significant CMV infection by day + 180 was lower in the valacyclovir group compared to the acyclovir group (18% vs. 57%, p = 0.0004). Patients receiving valacyclovir prophylaxis also had less severe infection evidenced by a reduction in CMV disease, lower peak CMV titers, delayed CMV reactivation, and less secondary neutropenia. CONCLUSION: Prospective evaluation of valacyclovir 1 g three times daily for viral prophylaxis following allogeneic HCT is warranted. Due to valacyclovir's favorable toxicity profile and affordable cost, it has the potential to benefit patients on a broad scale as an option for CMV prophylaxis.

RESUMO

Background: Filipino Americans (FAs) are the third-largest Asian American subgroup in the United States (US). Some studies showed that FAs experience more cardiometabolic diseases (CMDs) than other Asian subgroups and non-Hispanic Whites. The increased prevalence of CMD observed in FAs could be due to genetics and social/dietary lifestyles. While FAs are ascribed as an Asian group, they have higher burdens of CMD, and adverse social determinants of health compared to other Asian subgroups. Therefore, studies to elucidate how FAs might develop CMD and respond to medications used to manage CMD are warranted. The ultimate goals of this study are to identify potential mechanisms for reducing CMD burden in FAs and to optimize therapeutic drug selection. Collectively, these investigations could reduce the cardiovascular health disparities among FAs. Rationale and design: This is a cross-sectional epidemiological design to enroll 300 self-identified Filipino age 18 yrs. or older without a history of cancer and/or organ transplant from Virginia, Washington DC, and Maryland. Once consented, a health questionnaire and disease checklist are administered to participants, and anthropometric data and other vital signs are collected. When accessible, we collect blood samples to measure basic blood biochemistry, lipids, kidney, and liver functions. We also extract DNA from the blood or saliva for genetic and pharmacogenetic analyses. CMD prevalence in FAs will be compared to the US population. Finally, we will conduct multivariate analyses to ascertain the role of genetic and non-genetic factors in developing CMD in FAs. Virginia Commonwealth University IRB approved all study materials (Protocol HM20018500). Summary: This is the first community-based study to involve FAs in genomics research. The study is actively recruiting participants. Participant enrollment is ongoing. At the time of this publication, the study has enrolled 97 participants. This ongoing study is expected to inform future research to reduce cardiovascular health disparities among FAs.

RESUMO

BACKGROUND: Screening for food insecurity (FI) and providing nutrition care are important management strategies for chronic diseases, but rates are low. Aspects of team-based care and providers' nutrition competence may help inform interventions to improve these services. The objectives of this study were to describe US primary care providers' FI screening and nutrition care practices (counselling, referrals, and time spent counselling) and test for associations with scored measures of their perceptions of team-based care (care continuity, patient-centredness, coordination with external providers and resources) and nutrition competence (confidence counselling and attitudes towards nutrition). METHODS: Cross-sectional online survey data of primary care providers were described and analysed for associations using Wilcoxon rank sum tests. RESULTS: Of provider respondents (N = 92), 35% (n = 32) worked in clinics that screen for FI and had higher team perceptions (P = 0.006) versus those who do not. Those who reported counselling >30% patients about nutrition (57%, n = 52) and referring >10% patients to nutrition professionals (24%, n = 22) had significantly better attitudes towards nutrition (P = 0.013 and P = 0.04, respectively) compared with those with lower counselling and referral rates. Half (n = 46) of the providers reported spending >3-min counselling each patient about nutrition and had higher patient-centred care (P = 0.004) and nutrition competence (P < 0.001) compared with those who spent less time counselling. CONCLUSION: Providers in clinics that screen for FI had higher overall perceptions of team-based care, but their nutrition competence was not significantly different. Meanwhile, reported more time counselling was associated with a culture of patient-centredness. Promoting team-based care may be a mechanism for improving FI screening and nutrition care.

RESUMO

INTRODUCTION: Clinical preventive services can reduce mortality and morbidity, but Americans receive only half of the recommended care. Although wellness visits protect time for clinicians to review needs and discuss care with patients, studies have not shown that having a wellness visit improves health outcomes. This study seeks to understand the types of discussions and volume of care delivered during wellness visits. METHODS: Using a sample of 1,008 patients scheduled for a wellness visit from 22 primary care clinicians across 3 states from 2018 to 2019, electronic health records were reviewed, and a subset of visits was audio recorded. The discussion and delivery of clinical preventive services, as recommended by the U.S. Preventive Services Task Force, were measured, and new diagnoses were identified from the clinical preventive services. Analyses were completed in 2020. RESULTS: Even though patients were up to date with 80% of the recommended clinical preventive services 3 months after the visit, only 0.5% of patients were up to date with all the recommended clinical preventive services. On average, 6.9 clinical preventive service discussions occurred during each wellness visit on the basis of electronic health records review, and 7.7 clinical preventive services discussions occurred on the basis of audio recordings. An average of 0.4 new diagnoses was identified, including cancer diagnoses, cardiovascular risks, and infections. CONCLUSIONS: Wellness visits are an important time for patients and clinicians to discuss prevention strategies and to deliver recommended clinical preventive services, leading to the identification of previously unrecognized diagnoses. This will improve patients' health. Policies and incentives that promote wellness visits are important, and efforts are needed to deliver them to those most in need.

RESUMO

INTRODUCTION: In December 2013, cholesterol treatment guidelines changed the approach to statin therapy by recommending fixed doses of low-, medium-, or high-intensity statins based on cardiovascular risk. We sought to evaluate the guideline's adoption in a diverse group of practices. METHODS: Using a mixed-methods approach, we analyzed electronic health record data the year before and 2 years following guideline publication in 45 practices across 8 states. We examined associations based on patient, clinician, and practice characteristics and interviewed 24 clinicians and practice leaders to inform findings. RESULTS: The proportion of patients adherent with all recommendations 2 years after the guideline only increased from 18.5% to 20.3% (P < .01). There were clinically insignificant increases in statin use across risk strata (1.7% to 3.5%) and small increases in high-intensity statin use (2.6% to 4.6%). Only half of patients with cardiovascular disease (52.9%) were on any statin, not much different from patients at moderate (49.6% to 50.9%) or low (41.6% to 48.7%) risk. Multiple patient (risk, use of health care), clinician (age), and practice (type, rurality) factors were associated with statin use. Clinicians reported patient resistance to statins but liked having a risk calculator to guide discussions. CONCLUSION: Despite general agreement with statin benefit, the guideline was poorly implemented. Marginal differences in statin use between the highest and lower risk strata of patients is concerning. Rather than intensifying statin potency and recommending more patients take statins, guidelines may want to focus on ensuring that those who will benefit most get treatment.

RESUMO

OBJECTIVES: Lung cancer remains the leading cause of cancer-related deaths in the United States. In 2013, the US Preventive Services Task Force recommended annual screening for lung cancer with low-dose computed tomography in adults meeting certain criteria. This study seeks to assess lung cancer screening uptake in three health systems. SETTING: This study was part of a randomized controlled trial to engage underserved populations in preventive care and includes 45 primary care practices in eight states. METHODS: Practice and clinician characteristics were manually collected. Lung cancer was measured from electronic health record data. A generalized linear mixed model was used to assess characteristics associated with screening. RESULTS: Patient records between 2012 and 2016 were examined. Lung cancer screening uptake overall increased only slightly after the guideline change (2.8-5.6%, p < 0.01). One health system did not show an increase in uptake (0.2-0.1%, p = 0.32), another had a clinically insignificant increase (1.5-2.9%, p < 0.01), and the third nearly doubled its higher baseline screening rate (10.4-19.1%, p < 0.01). Within the third health system, patients more likely to be screened were older, male, had more comorbid conditions, visited the office more frequently, were seen in practices closer to the screening clinic, or were uninsured or covered by Medicare or Medicaid. CONCLUSIONS: Certain patients appeared more likely to be screened. The only health system with increased lung cancer screening explicitly promoted screening rather than relying on clinicians to implement the new guideline. Systems approaches may help increase the low uptake of lung cancer screening.

RESUMO

INTRODUCTION: Screening for colorectal cancer is beneficial. Yet, screening remains suboptimal, and underserved populations are at greater risk for not being appropriately screened. Although many barriers to screening are understood, less is known about how the decision-making process on whether to receive colonoscopy or stool testing influences screening. METHODS: As part of a randomized controlled trial to test engaging underserved populations in preventive care through online, personalized, educational material, 2417 patients aged 50 to 74 years were randomly selected from the 70,998 patients with an office visit the year prior and mailed a survey to assess decision-making for colorectal cancer screening. Twenty practices in practice-based research networks from 5 diverse states participated. Survey data were supplemented with electronic health record data. RESULTS: Among respondents, 64% were or became up to date with screening within 3 months of their office visit. The main factor associated with being up to date was the length of the patient-clinician relationship (<6 months vs 5+ years: odds ratio [OR], 0.49; 95% CI, 0.30-0.80). Sharing the decision about screening options with the clinician was a predictor for being up to date compared with patients who made the decision for themselves (OR, 1.75; 95% CI, 1.27-2.44). Only 36% of patients reported being given a choice about screening options. Traditional factors like race, employment, insurance, and education were not associated with screening. CONCLUSIONS: Having a long-term relationship with a primary care clinician and sharing decisions may be key drivers to ensure evidence-based preventive care for underserved populations.

RESUMO

BACKGROUND: Unhealthy alcohol use is the third leading cause of preventable death in the United States. Evidence demonstrates that screening for unhealthy alcohol use and providing persons engaged in risky drinking with brief behavioral and counseling interventions improves health outcomes, collectively termed screening and brief interventions. Medication assisted therapy (MAT) is another effective method for treatment of moderate or severe alcohol use disorder. Yet, primary care clinicians are not regularly screening for or treating unhealthy alcohol use. METHODS AND ANALYSIS: We are initiating a clinic-level randomized controlled trial aimed to evaluate how primary care clinicians can impact unhealthy alcohol use through screening, counseling, and MAT. One hundred and 25 primary care practices in the Virginia Ambulatory Care Outcomes Research Network (ACORN) will be engaged; each will receive practice facilitation to promote screening, counseling, and MAT either at the beginning of the trial or at a 6-month control period start date. For each practice, the intervention includes provision of a practice facilitator, learning collaboratives with three practice champions, and clinic-wide information sessions. Clinics will be enrolled for 6-12 months. After completion of the intervention, we will conduct a mixed methods analysis to identify changes in screening rates, increase in provision of brief counseling and interventions as well as MAT, and the reduction of alcohol intake for patients after practices receive practice facilitation. DISCUSSION: This study offers a systematic process for dissemination and implementation of the evidence-based practice of screening, counseling, and treatment for unhealthy alcohol use. Practices will be asked to implement a process for screening, counseling, and treatment based on their practice characteristics, patient population, and workflow. We propose practice facilitation as a robust and feasible intervention to assist in making changes within the practice. We believe that the process can be replicated and used in a broad range of clinical settings; we anticipate this will be supported by our evaluation of this approach.

RESUMO

BACKGROUND: Although Web-based questionnaires are an efficient, increasingly popular mode of data collection, their utility is often challenged by high participant dropout. Researchers can gain insight into potential causes of high participant dropout by analyzing the dropout patterns. OBJECTIVE: This study proposed the application of and assessed the use of user-specified and existing hypothesis testing methods in a novel setting-survey dropout data-to identify phases of higher or lower survey dropout. METHODS: First, we proposed the application of user-specified thresholds to identify abrupt differences in the dropout rate. Second, we proposed the application of 2 existing hypothesis testing methods to detect significant differences in participant dropout. We assessed these methods through a simulation study and through application to a case study, featuring a questionnaire addressing decision-making surrounding cancer screening. RESULTS: The user-specified method set to a low threshold performed best at accurately detecting phases of high attrition in both the simulation study and test case application, although all proposed methods were too sensitive. CONCLUSIONS: The user-specified method set to a low threshold correctly identified the attrition phases. Hypothesis testing methods, although sensitive at times, were unable to accurately identify the attrition phases. These results strengthen the case for further development of and research surrounding the science of attrition.

RESUMO

BACKGROUND: Providers have expressed concern about patient access to clinical notes. There is the possibility that providers may linguistically censor notes knowing that patients have access. PURPOSE: Qualitative interviews and a pre- and post- linguistic analysis of the implementation of OpenNotes was performed to determine whether oncologists changed the content and style of their notes. METHODS: Mixed methods were utilized, including 13 semi-structured interviews with oncologists and random effects modeling of over 500 clinical notes. The Linguistic Inquiry and Word Count program was used to evaluate notes for emotions, thinking styles, and social concerns. RESULTS: No significant differences from pre- and post-implementation of OpenNotes was found. Thematic analysis revealed that oncologists were concerned that changing their notes would negatively impact multidisciplinary communication. However, oncologists acknowledged that notes could be more patient-friendly and may stimulate patient-provider communication. CONCLUSIONS: Although oncologists were aware that patients could have access, they felt strongly about not changing the content of notes. A comparison between pre- and post-implementation confirmed this view and found that notes did not change. PRACTICE IMPLICATIONS: Patient access to oncologist's notes may serve as an opportunity to reinforce important aspects of the consultation.

RESUMO

PURPOSE: The shift from infusion to oral oncolytic therapy presents challenges to oncology practitioners. The purpose of this study was to describe how a statewide quality-improvement collaborative can enhance quality of care for patients receiving oral oncolytic therapy. METHODS: The Michigan Oncology Quality Consortium hosted a series of learning sessions focused on oral oncolytic quality improvement, providing multiple resources to oncology community practices. The first five participating practices reported which of the evidence-based Michigan Oncology Quality Consortium resources provided were implemented at their site. They also performed prepost self-assessments in October 2013 and April 2015 and another in December 2017 to assess sustainability. Concordance with the ASCO Quality Oncology Practice Initiative oral chemotherapy standards, including documentation (five measures), patient education (seven measures), and follow-up/monitoring (four measures), was compared. RESULTS: All practices showed improvement between 2013 and 2015 in documentation (32% to 88%; P = .03), patient education (37% to 100%; P could not be calculated), and monitoring (40% to 80%; P > .2). Overall, a significant improvement in concordance was observed (36% to 91%; P = .03). Use of resources from each practice varied, and practices that used more resources showed greater improvements. There was a slight decrease in overall concordance between 2015 and 2017, which was not found to be significant (91% to 84%; P = .53). CONCLUSION: Use of tools from a quality-improvement collaborative improved concordance with national standards of care. Large-scale deployment of this model program may provide a clinically efficient and effective mechanism to enhance widespread change.

RESUMO

Allogeneic hematopoietic cell transplantation (HCT) is a curative option for patients with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS), but carries a high risk of relapse. This retrospective review evaluates the effectiveness of maintenance azacitidine in high-risk AML and MDS patients to reduce the probability of relapse. Twenty-five patients who received maintenance azacitidine were matched to historical controls in a two-to-one ratio based on diagnosis, donor type, conditioning regimen intensity, and age. Over 90% of patients received myeloablative conditioning. There was no difference in time to hematologic relapse, overall survival, or non-relapse mortality. Maintenance therapy was stopped early in 72% of patients due to graft-versus-host-disease, relapse, infection, and intolerance (13 of 25 patients received less than 4 cycles). There was a trend towards higher toxicity in the azacitidine group. The use of prophylactic azacitidine following myeloablative allogeneic HCT outside a clinical trial cannot be recommended at this time.

RESUMO

Lymphoid recovery following myeloablative stem cell transplantation (SCT) displays a logistic pattern of exponential growth followed by a plateau. Within this logistic framework, lymphoid recovery is characterized by the parameters R (slope of ascent), a (time of maximal rate of ascent) and K (plateau), the 'steady-state' lymphocyte count. A retrospective analysis of allogeneic SCT performed from 2008 to 2013 was undertaken to compare lymphoid recovery and clinical outcomes in 131 patients with acute myelogenous leukemia, acute lymphocytic leukemia, and myelodysplastic syndromes. Using Prism software, a logistic curve was successfully fit to the absolute lymphocyte count recovery in all patients. Patients were classified according to the magnitude and rate of lymphoid recovery; pattern A achieved an absolute lymphocyte counts (ALC) of >1000/µL by day 45, pattern B an ALC 500 < x < 1000/µL, and pattern C an ALC <500/µL. Pattern A was characterized by a higher mean K (p < .0001) compared with patterns B and C. Patients with patterns B and C were more likely to have mixed T cell chimerism at 90 d following SCT (p = .01). There was a trend towards improved survival (and relapse-free survival) in those with pattern A and B at 1 year compared to pattern C (p = .073). There was no difference in cGVHD (p = .42) or relapse (p = .45) between pattern types. Cytomegalovirus (CMV), aGVHD, and all relapse were heralded by deviation from logistic behavior. Pattern C patients were more likely to require donor lymphocyte infusion (DLI) (p = .017). Weaning of tacrolimus post-transplant was associated with a second, separate logistic expansion in some patients. This study demonstrated that lymphoid reconstitution follows a prototypical logistic recovery and that pattern observed correlates with T cell chimerism and need for DLI, and may influence survival.

RESUMO

In this study, we used a rapid, highly-sensitive, single-cell biomass measurement method, Live Cell Interferometry (LCI), to measure biomass in populations of CD3 + T cells isolated from hematopoietic stem cell transplant (SCT) patients at various times pre- and post-transplant (days 0-100). CD3 + T cell 'mass spectra' were obtained from five autologous and 20 allogenic transplant recipients. We found a pronounced rise in median T cell biomass (+25%; p <0.001) shortly after transplant (day 14), which moderated by day 60. Further, the inter-patient and intra-patient cell masses were most variable at days 14 and 30 post-transplant. T cell biomass trends were similar in both autologous and allogenic transplant recipients. These data suggest that T cell biomass changes are associated with immune reconstitution occurring in the first few weeks post-transplant. To our knowledge, this is the first time single-cell biomass measurements have been studied in human clinical trials. With refinement, these data may prove useful in guiding the withdrawal of immunosuppression following SCT, reducing the likelihood of Graft-Versus-Host Disease or cancer relapse occurring.

RESUMO

INTRODUCTION: Engaging patients to make informed choices is paramount but difficult in busy practices. This study sought to engage patients outside the clinical setting to better understand how they approach cancer screening decisions, including their primary concerns and their preferences for finalizing their decision. METHODS: Twelve primary care practices offering patients an online personal health record invited eligible patients to complete a 17-item online interactive module. Among 11,458 registered users, invitations to complete the module were sent to adults aged 50-74 years who were overdue for colorectal cancer screening and to women aged 40-49 years and men aged 55-69 who had not undergone a recent mammogram or prostate-specific antigen test, respectively. RESULTS: The module was started by 2,355 patients and completed by 903 patients. Most respondents (76.8%) knew they were eligible for screening. Preferred next steps were talking to the clinician (76.6%), reading/research (28.6%), and consulting trusted friends/family (16.4%). Priority topics included how much screening improves life expectancy, comparative test performance, and the prevalence/health risks of the cancer. Leading fears were getting cancer/delayed detection (79.2%), abnormal results (40.5%), and testing complications (39.1%), the last referring to false test results, medical complications, or unnecessary treatments. Men eligible for prostate-specific antigen screening were more likely than women eligible for mammography to express concerns about testing complications and to prioritize weighing pros and cons over gut feelings (p<0.05). CONCLUSIONS: Although this sample was predisposed to screening, most patients wanted help in finalizing their decision. Many wanted to weigh the pros and cons and expressed fears of potential harms from screening. Understanding how patients approach decisions may help design more effective engagement strategies.

RESUMO

PURPOSE: Technology could transform routine decision making by anticipating patients' information needs, assessing where patients are with decisions and preferences, personalizing educational experiences, facilitating patient-clinician information exchange, and supporting follow-up. This study evaluated whether patients and clinicians will use such a decision module and its impact on care, using 3 cancer screening decisions as test cases. METHODS: Twelve practices with 55,453 patients using a patient portal participated in this prospective observational cohort study. Participation was open to patients who might face a cancer screening decision: women aged 40 to 49 who had not had a mammogram in 2 years, men aged 55 to 69 who had not had a prostate-specific antigen test in 2 years, and adults aged 50 to 74 overdue for colorectal cancer screening. Data sources included module responses, electronic health record data, and a postencounter survey. RESULTS: In 1 year, one-fifth of the portal users (11,458 patients) faced a potential cancer screening decision. Among these patients, 20.6% started and 7.9% completed the decision module. Fully 47.2% of module completers shared responses with their clinician. After their next office visit, 57.8% of those surveyed thought their clinician had seen their responses, and many reported the module made their appointment more productive (40.7%), helped engage them in the decision (47.7%), broadened their knowledge (48.1%), and improved communication (37.5%). CONCLUSIONS: Many patients face decisions that can be anticipated and proactively facilitated through technology. Although use of technology has the potential to make visits more efficient and effective, cultural, workflow, and technical changes are needed before it could be widely disseminated.

RESUMO

BACKGROUND: Electronic surveys are convenient, cost effective, and increasingly popular tools for collecting information. While the online platform allows researchers to recruit and enroll more participants, there is an increased risk of participant dropout in Web-based research. Often, these dropout trends are simply reported, adjusted for, or ignored altogether. OBJECTIVE: To propose a conceptual framework that analyzes respondent attrition and demonstrates the utility of these methods with existing survey data. METHODS: First, we suggest visualization of attrition trends using bar charts and survival curves. Next, we propose a generalized linear mixed model (GLMM) to detect or confirm significant attrition points. Finally, we suggest applications of existing statistical methods to investigate the effect of internal survey characteristics and patient characteristics on dropout. In order to apply this framework, we conducted a case study; a seventeen-item Informed Decision-Making (IDM) module addressing how and why patients make decisions about cancer screening. RESULTS: Using the framework, we were able to find significant attrition points at Questions 4, 6, 7, and 9, and were also able to identify participant responses and characteristics associated with dropout at these points and overall. CONCLUSIONS: When these methods were applied to survey data, significant attrition trends were revealed, both visually and empirically, that can inspire researchers to investigate the factors associated with survey dropout, address whether survey completion is associated with health outcomes, and compare attrition patterns between groups. The framework can be used to extract information beyond simple responses, can be useful during survey development, and can help determine the external validity of survey results.

RESUMO

Patient-centered health risk assessments (HRAs) that screen for unhealthy behaviors, prioritize concerns, and provide feedback may improve counseling, goal setting, and health. To evaluate the effectiveness of routinely administering a patient-centered HRA, My Own Health Report, for diet, exercise, smoking, alcohol, drug use, stress, depression, anxiety, and sleep, 18 primary care practices were randomized to ask patients to complete My Own Health Report (MOHR) before an office visit (intervention) or continue usual care (control). Intervention practice patients were more likely than control practice patients to be asked about each of eight risks (range of differences 5.3-15.8 %, p < 0.001), set goals for six risks (range of differences 3.8-16.6 %, p < 0.01), and improve five risks (range of differences 5.4-13.6 %, p < 0.01). Compared to controls, intervention patients felt clinicians cared more for them and showed more interest in their concerns. Patient-centered health risk assessments improve screening and goal setting.Trial RegistrationClinicaltrials.gov identifier: NCT01825746.

RESUMO

PURPOSE: To determine if there is a difference in toxicity and effectiveness between obese and non-obese patients who receive high-dose cyclophosphamide (Cy) prior to allogeneic hematopoietic stem cell transplant (allo-HCT). METHODS: Patients were included in this study if they were at least 18 years of age and received high-dose Cy in combination with total body irradiation (CyTBI) or busulfan (BuCy) prior to allo-HCT between 1 January 2008 and 29 February 2012. The primary endpoint was the difference in overall toxicity between obese and non-obese patients. Secondary objectives examined differences in effectiveness between groups assessed by relapse at day +100, relapse at 1 year, death at 1 year, chimerisms at days +30, +60, and +90, and incidence of acute graft versus host disease (aGVHD). RESULTS: Sixty-one patients met the inclusion criteria, 28 obese and 33 non-obese. Overall toxicity was greater in obese patients compared to non-obese patients (82% vs. 52%, OR 4.3 [95% CI 1.3-14.1]; p = 0.01), which was driven by a greater incidence of renal dysfunction (79% vs. 48%, OR 3.9 [95% CI 1.3-12.1]; p = 0.02). There were no differences in rates of grade 3 or 4 toxicity, hepatic dysfunction, or any measure of effectiveness between groups. CONCLUSION: Obese patients receiving high-dose Cy and allo-HCT are at increased risk for toxicity, although there appears to be no difference in the rate of relapse or survival between obese and non-obese patients.
