    Developing Predictors of Long-Term Adherence to Exercise Among Older Veterans and Spouses.
    (Journal of applied gerontology : the official journal of the Southern Gerontological Society, 2019-09-21) Brown, Candace S; Sloane, Richard; Morey, Miriam C
    Behavior change theory was used to explore predictors of long-term adherence (≥2 years) to exercise. A retrospective analysis of data from participants (N = 97) who reached a 6-month follow-up, which served as the baseline, was evaluated for completion of yearly follow-up surveys. Variables examined at baseline, which included age, race, gender, body mass index (BMI), and self-report of comorbidities, symptoms, physical function, and a Barriers Specific Self-Efficacy Scale, were examined with significance set at p < .05. Lower BMI (29.1 ± 5.1 vs. 31.6 ± 6.5, p = .047) and higher self-efficacy to overcome environmental barriers (p = .016) and social isolation (p = .05) were associated with long-term adherence. Self-efficacy to overcome environmental and social barriers, such as inclement weather, access to exercise site, and opportunities for group-based exercise, should be addressed to promote long-term adherence to exercise among older adults.

    Digital Medicine System in Veterans With Severe Mental Illness: Feasibility and Acceptability Study.
    (JMIR formative research, 2022-12) Gonzales, Sarah; Okusaga, Olaoluwa O; Reuteman-Fowler, J Corey; Oakes, Megan M; Brown, Jamie N; Moore, Scott; Lewinski, Allison A; Rodriguez, Cristin; Moncayo, Norma; Smith, Valerie A; Malone, Shauna; List, Justine; Cho, Raymond Y; Jeffreys, Amy S; Bosworth, Hayden B

    Background

    Suboptimal medication adherence is a significant problem for patients with serious mental illness. Measuring medication adherence through subjective and objective measures can be challenging, time-consuming, and inaccurate.

    Objective

    The primary purpose of this feasibility and acceptability study was to evaluate the impact of a digital medicine system (DMS) among Veterans (patients) with serious mental illness as compared with treatment as usual (TAU) on medication adherence.

    Methods

    This open-label, 2-site, provider-randomized trial assessed aripiprazole refill adherence in Veterans with schizophrenia, schizoaffective disorder, bipolar disorder, or major depressive disorder. We randomized 26 providers such that their patients either received TAU or DMS for a period of 90 days. Semistructured interviews with patients and providers were used to examine the feasibility and acceptability of using the DMS.

    Results

    We enrolled 46 patients across 2 Veterans Health Administration sites: 21 (46%) in DMS and 25 (54%) in TAU. There was no difference in the proportion of days covered by medication refill over 3 and 6 months (0.82, SD 0.24 and 0.75, SD 0.26 in DMS vs 0.86, SD 0.19 and 0.82, SD 0.21 in TAU, respectively). The DMS arm had 0.85 (SD 0.20) proportion of days covered during the period they were engaged with the DMS (mean 144, SD 100 days). Interviews with patients (n=14) and providers (n=5) elicited themes salient to using the DMS. Patient findings described the positive impact of the DMS on medication adherence, challenges with the DMS patch connectivity and skin irritation, and challenges with the DMS app that affected overall use. Providers described an overall interest in using a DMS as an objective measure to support medication adherence in their patients. However, providers described challenges with the DMS dashboard and integrating DMS data into their workflow, which decreased the usability of the DMS for providers.

    Conclusions

    There was no observed difference in refill rates. Among those who engaged in the DMS arm, the proportion of days covered by refills were relatively high (mean 0.85, SD 0.20). The qualitative analyses highlighted areas for further refinement of the DMS.

    Early Survivorship after Liver Transplantation: A Qualitative Study Identifying Challenges in Recovery From The Patient and Caregiver Perspective.
    (Liver transplantation : official publication of the American Association for the Study of Liver Diseases and the International Liver Transplantation Society, 2021-09-16) Lieber, Sarah R; Kim, Hannah P; Baldelli, Luke; Nash, Rebekah; Teal, Randall; Magee, Gabrielle; Desai, Chirag S; Loiselle, Marci M; Lee, Simon C; Singal, Amit G; Marrero, Jorge A; Barritt, A Sidney; Evon, Donna M

    Background

    Survivorship after liver transplantation (LT) is a novel concept providing a holistic view of the arduous recovery experienced after transplantation. We explored components of early survivorship including physical, emotional, and psychocological challenges to identify intervention targets for improving the recovery process of LT recipients and caregivers.

    Methods

    Twenty in-person interviews were conducted among adults 3-6 months post-LT. Trained qualitative research experts conducted interviews, coded, and analyzed transcripts to identify relevant themes and representative quotes.

    Results

    Early survivorship comprises overcoming: 1) physical challenges-the most-challenging experiences involving mobility, driving, dietary modifications, and medication adherence and 2) emotional and psychological challenges-including new health concerns, financial worries, body image/identity struggles, social isolation, dependency issues, and concerns about never returning to normal. Etiology of liver disease informed survivorship experiences including some patients with hepatocellular carcinoma expressing decisional regret or uncertainty in light of their post-LT experiences. Important topics were identified that framed LT recovery including setting expectations about waitlist experiences, hospital recovery, and ongoing medication requirements.

    Conclusion

    Early survivorship after LT within the first six months involves a wide array of physical, emotional and psychological challenges. Patients and caregivers identified what they wish they had known prior to transplant and strategies for recovery, which can inform targeted LT survivorship interventions.

    Health coaching for glaucoma care: a pilot study using mixed methods.
    (Clin Ophthalmol, 2015) Vin, Anita; Schneider, Suzanne; Muir, Kelly W; Rosdahl, Jullia A
    INTRODUCTION: Adherence to glaucoma medications is essential for successful treatment of the disease but is complex and difficult for many of our patients. Health coaching has been used successfully in the treatment of other chronic diseases. This pilot study explores the use of health coaching for glaucoma care. METHODS: A mixed methods study design was used to assess the health coaching intervention for glaucoma patients. The health coaching intervention consisted of four to six health coaching sessions with a certified health coach via telephone. Quantitative measures included demographic and health information, adherence to glaucoma medications (using the visual analog adherence scale and medication event monitoring system), and an exit survey rating the experience. Qualitative measures included a precoaching health questionnaire, notes made by the coach during the intervention, and an exit interview with the subjects at the end of the study. RESULTS: Four glaucoma patients participated in the study; all derived benefits from the health coaching. Study subjects demonstrated increased glaucoma drop adherence in response to the coaching intervention, in both visual analog scale and medication event monitoring system. Study subjects' qualitative feedback reflected a perceived improvement in both eye and general health self-care. The subjects stated that they would recommend health coaching to friends or family members. CONCLUSION: Health coaching was helpful to the glaucoma patients in this study; it has the potential to improve glaucoma care and overall health.

    Is there a nonadherent subtype of hypertensive patient? A latent class analysis approach.
    (Patient preference and adherence, 2010-07) Trivedi, Ranak B; Ayotte, Brian J; Thorpe, Carolyn T; Edelman, David; Bosworth, Hayden B
    To determine subtypes of adherence, 636 hypertensive patients (48% White, 34% male) reported adherence to medications, diet, exercise, smoking, and home blood pressure monitoring. A latent class analysis approach was used to identify subgroups that adhere to these five self-management behaviors. Fit statistics suggested two latent classes. The first class (labeled "more adherent") included patients with greater probability of adhering to recommendations compared with the second class (labeled "less adherent") with regard to nonsmoking (97.7% versus 76.3%), medications (75.5% versus 49.5%), diet (70.7% versus 46.9%), exercise (63.4% versus 27.2%), and blood pressure monitoring (32% versus 3.4%). Logistic regression analyses used to characterize the two classes showed that "more adherent" participants were more likely to report full-time employment, adequate income, and better emotional and physical well-being. Results suggest the presence of a less adherent subtype of hypertensive patients. Behavioral interventions designed to improve adherence might best target these at-risk patients for greater treatment efficiency.

    Psychosocial Assessment of Candidates for Transplantation (PACT) Score Identifies High Risk Patients in Pediatric Renal Transplantation.
    (Frontiers in pediatrics, 2019-01) Freischlag, Kyle W; Chen, Vivian; Nagaraj, Shashi K; Chua, Annabelle N; Chen, Dongfeng; Wigfall, Delbert R; Foreman, John W; Gbadegesin, Rasheed; Vikraman, Deepak; Chambers, Eileen T
    Background: Currently, there is no standardized approach for determining psychosocial readiness in pediatric transplantation. We examined the utility of the Psychosocial Assessment of Candidates for Transplantation (PACT) to identify pediatric kidney transplant recipients at risk for adverse clinical outcomes. Methods: Kidney transplant patients <21-years-old transplanted at Duke University Medical Center between 2005 and 2015 underwent psychosocial assessment by a social worker with either PACT or unstructured interview, which were used to determine transplant candidacy. PACT assessed candidates on a scale of 0 (poor candidate) to 4 (excellent candidate) in areas of social support, psychological health, lifestyle factors, and understanding. Demographics and clinical outcomes were analyzed by presence or absence of PACT and further characterized by high (≥3) and low (≤2) scores. Results: Of 54 pediatric patients, 25 (46.3%) patients underwent pre-transplant evaluation utilizing PACT, while 29 (53.7%) were not evaluated with PACT. Patients assessed with PACT had a significantly lower percentage of acute rejection (16.0 vs. 55.2%, p = 0.007). After adjusting for HLA mismatch, a pre-transplant PACT score was persistently associated with lower odds of acute rejection (Odds Ratio 0.119, 95% Confidence Interval 0.027-0.52, p = 0.005). In PACT subsection analysis, the lack of family availability (OR 0.08, 95% CI 0.01-0.97, p = 0.047) and risk for psychopathology (OR 0.34, 95% CI 0.13-0.87, p = 0.025) were associated with a low PACT score and post-transplant non-adherence. Conclusions: Our study highlights the importance of standardized psychosocial assessments and the potential use of PACT in risk stratifying pre-transplant candidates.

    Race and sex differences in dropout from the STRRIDE trials.
    (Frontiers in sports and active living, 2023-01) Collins, Katherine A; Huffman, Kim M; Wolever, Ruth Q; Smith, Patrick J; Siegler, Ilene C; Ross, Leanna M; Jakicic, John M; Costa, Paul T; Kraus, William E

    Purpose

    To determine if race and sex differences exist in determinants and timing of dropout among individuals enrolled in an exercise and/or caloric restriction intervention.

    Methods

    A total of 947 adults with dyslipidemia (STRRIDE I, STRRIDE AT/RT) or prediabetes (STRRIDE-PD) were randomized to either inactive control or to 1 of 10 exercise interventions, ranging from doses of 8-23 kcal/kg/week, intensities of 50%-75% V˙O2 peak, and durations of 6-8 months. Two groups included resistance training, and one included a dietary intervention (7% weight loss goal). Dropout was defined as an individual withdrawn from the study, with the reasons for dropout aggregated into determinant categories. Timing of dropout was defined as the last session attended and aggregated into phases (i.e., "ramp" period to allow gradual adaptation to exercise prescription). Utilizing descriptive statistics, percentages were generated according to categories of determinants and timing of dropout to describe the proportion of individuals who fell within each category.

    Results

    Black men and women were more likely to be lost to follow-up (Black men: 31.3% and Black women: 19.6%), or dropout due to work responsibilities (15.6% and 12.5%), "change of mind" (12.5% and 8.9%), transportation issues (6.3% and 3.6%), or reported lack of motivation (6.3% and 3.6%). Women in general noted lack of time more often than men as a reason for dropout (White women: 22.4% and Black women: 22.1%). Regardless of race and sex, most participants dropped out during the ramp period of the exercise intervention; with Black women (50%) and White men (37.1%) having the highest dropout rate during this period.

    Conclusion

    These findings emphasize the importance of targeted retention strategies when aiming to address race and sex differences that exist in determinants and timing of dropout among individuals enrolled in an exercise and/or caloric restriction intervention.

    The new landscape of medication adherence improvement: where population health science meets precision medicine.
    (Patient preference and adherence, 2018-01) Zullig, Leah L; Blalock, Dan V; Dougherty, Samantha; Henderson, Rochelle; Ha, Carolyn C; Oakes, Megan M; Bosworth, Hayden B
    Despite the known health and economic benefits of medications, nonadherence remains a significant, yet entirely preventable public health burden. Over decades, there have been numerous research studies evaluating health interventions and policy efforts aimed at improving adherence, yet no universal or consistently high impact solutions have been identified. At present, new challenges and opportunities in policy and the movement toward value-based care should foster an environment that appreciates adherence as a mechanism to improve health outcomes and control costs (eg, fewer hospitalizations, reduced health care utilization). Our objective was to provide a commentary on recent changes in the landscape of research and health policy directed toward improving adherence and an actionable agenda to achieve system level savings and improved health by harnessing the benefits of medications. Specifically, we address the complementary perspectives of precision medicine and population health management; integrating data sources to develop innovative measurement of adherence and target adherence interventions; and behavioral economics to determine appropriate incentives.
