Background Medication nonadherence has been associated with poor outcomes in transplant recipients yet identifying these behaviors pre-transplant remains challenging. The simplified medication adherence questionnaire (SMAQ) is a brief, reliable instrument to assess medication adherence. The aim of this study was to perform SMAQ testing on thoracic organ candidates and examine correlations between these scores and individual patient factors predicting medication nonadherence. Methods Consenting waitlisted lung, heart, and heart-lung transplant candidates from six thoracic transplant centers were mailed a survey that included demographic information and the Simplified Medication Adherence Questionnaire (SMAQ). Univariate logistic regression analysis was performed to assess association between pre-transplant medication adherence and demographic characteristics, psychosocial factors, and mortality. Results Among 298 participants, 60.7% were medication nonadherent. Nonadherence was associated with some college education (OR: 1.73; CI: 1.06, 2.81), lower positive affect (OR: 0.95; CI: 0.92, 0.99), and higher uncertainty (OR: 1.02; CI: 1.01, 1.04). Higher positivity ratio predicted adherence. Conclusion Identifiable patient-specific characteristics associated with medication nonadherence can be screened for during thoracic transplant evaluation. Interventions aimed at improving these factors during the pre-transplant period may improve clinical post-transplant outcomes, however, larger studies are needed to validate these findings.

Introduction Despite its demonstrated effectiveness at improving outcomes, pulmonary rehabilitation (PR) for chronic obstructive pulmonary disease (COPD) is underutilized. Sensor-generated data from wearable devices have the potential to mitigate this challenge by generating digital endpoints that provide insights into patient behaviors at home; however, there is no consensus on how to measure home-based PR (HBPR) outcomes with these tools. This review aims to describe (1) the most frequent digital endpoints used in HBPR studies and (2) the devices used to capture these endpoints, summarizing gaps in their applications to HBPR for COPD patients. Methods We completed a scoping review using the PRISMA checklist across databases (Web of Science, Scopus, and OVID) from January 1, 2005 to June 1, 2025. We included peer-reviewed articles on HBPR for COPD, excluding reviews, commentaries/editorials, poster abstracts, and conference proceedings. Eligible articles included cohort studies and clinical trials of adult patients (age ≥ 18 years) with COPD participating in HBPR that include one or more digital endpoints. Results Among eligible articles ( n = 218), 13 (6.0%) met inclusion criteria, the majority of which were published after 2020 (61.5%). Most studies enrolled fewer than 100 COPD patients (76.9%) for an average monitoring period of 12.5 weeks. Activity trackers were the most commonly used device (46.2%) to capture data. The most frequently used digital endpoints were step count (84.6%), time spent active (38.5%), and time spent sedentary (30.8%). Two study designs were used: randomized controlled trial (76.9%) and observational cohort. Study designs were heterogenous with more than one-third (38.5%) presenting a lack of statistically significant results. Discussion Although we identified analogous digital endpoints in some studies, dissimilar methods and study designs remain barriers to synthesizing results generated from HBPR programs for COPD. Wearable devices have the potential to build novel PR models, but more work is needed to translate real-world data into clinically meaningful measures. Future research should elucidate which participants would benefit most from and complete HBPR to build an evidence base for the validation of HBPR-relevant digital endpoints, particularly those derived from less common sources like cardiovascular and sleep measures.

Purpose: Lifestyle and social frailty factors are a new focus in the multidimensional concept of frailty, as recent reports have found strong associations with negative health outcomes. We searched for specific social and lifestyle frailty factors independently associated with 5-year survival and the risk of hospitalization in patients with severe chronic obstructive pulmonary disease (COPD). Methods: We retrospectively analyzed questionnaire data from the National Emphysema Treatment Trial (NETT) and identified items related to the published definition of social frailty. Classification and Regression Tree, a machine learning method, was used to select variables most strongly associated with survival time or hospitalizations beyond 12 months of NETT study enrollment. Kaplan-Meier curves, log-rank tests, and Cox proportional hazards models were used to determine relationships between social/lifestyle variables and hospitalization and survival. Results: Four social and lifestyle frailty factors were significantly related to survival (impaired lifting, bathing and dressing, in-store shopping, and loneliness). Two social and lifestyle frailty factors were significantly related to risk of hospitalization (emotional distress and difficulty performing work or activities). A combination of 6 questions provided clinical phenotypes that were robustly and independently associated with mortality risk and hospitalization with hazard ratios that ranged from 2.4 to 11.2 and 2.2 to 3.5 for survival and hospitalization, respectively, after adjustment for age, sex, disease severity, and physical frailty. Conclusion: Lifestyle and social frailty factors that could be easily identified in practice may represent a novel approach to a multidimensional frailty assessment to predict survival and hospitalization in patients with severe COPD.

11118 Background: Lung cancer survivors experience more physical and mental challenges, heavier symptom burden, and poorer quality of life than survivors of other cancers. Many symptoms persist or worsen for survivors beyond 5 years of cancer diagnosis, referred as long-term lung cancer survivors (LTLCS). Social determinants of health (SDoH) factors negatively impact patient reported outcomes (PROs) among cancer survivors, but their role in outcomes is under reported in lung cancer survivors and unknown in LTLCS. We investigated the impact of SDoH on PROs in a 20-year prospective lung cancer cohort. Methods: Our cohort includes 19,251 lung cancer patients (cases) diagnosed from 1997 through 2016 and followed up to 27 years, of whom 4799 (25%) became LTLCS. SDoH information was obtained by a lung cancer study PRO questionnaire or an institution SDoH questionnaire. Analyzed in this report are 2982 cases and 480 controls who had a low-dose chest CT scan and were ruled out for cancer, all answered at least one PRO questionnaire (first response); and 1366 LTLCS answered 5 years after diagnosis (long-term response). Along with fatigue and dyspnea, 5 SDoH variables, i.e., financial concerns, legal concerns, family and friends support, spiritual well-being, and social activity were scored on a 0 (worst) - 10 (best) scale and dichotomized as 0-5 (deficit/worse/lower) or 6-10 (no deficit/better/higher). We also assessed employment and health-related work experience. A difference of 1.0 unit or more in score was considered clinically meaningful along with a 2-sided test P-value less than 0.05; Chi-square or Fisher’s Exact Test and Kruskal-Wallis test were used accordingly. Results: Compared to controls, cases were younger (mean age: 62 vs. 65 years, P<0.05); more women than men reported worse financial concerns (56% vs. 38%, P<0.01) and lower spiritual well-being (43% vs. 26%, P=0.04) at first response; this sex disparity reduced but remained significant at long-term. Worse dyspnea (4.4-4.8 vs. 5.6) and fatigue (4.7-4.8 vs. 5.8-5.9) were seen in cases with more financial and legal concerns compared to those with fewer concerns (Ps<0.01). Cases with higher family and friends support, spiritual well-being and social activity had less dyspnea (5.7-6.0 vs. 4.2-4.5) and fatigue (5.5-5.9 vs. 3.9-4.4) than those with lower scores (Ps<0.04). Employment and health-related work experience data were provided by 2213 responders: Comparing 1735 cases to 478 controls, a lower proportion of cases was employed (28% vs. 39%), more cases “often felt tired after work” (49% vs. 28%), and more cases had “quite a lot” of difficulty in daily work or could not work at all” (26% vs. 9%, Ps<0.01). Conclusions: We found that in lung cancer survivors, more women than men reported worse financial concerns, and lower SDoH status was correlated with worse dyspnea and fatigue, indicating SDoH-driven interventions are important to improve lung cancer survivors’ PROs.

A self-management intervention is a personalized approach to individuals aiming to engage individuals in a behavior change to develop skills to live better with their condition. Self-management involves an iterative process between participants and providers in which goals are formulated and feedback is given. All respiratory societies advocate self-management as part of chronic care because it may improve quality of life and health-care utilization. Self-management is an integral part of pulmonary rehabilitation. Self-management interventions usually involve education and exercise prescription, and that is an asset of current programs; however, recent reports indicate that effective strategies for motivation and a behavior change focus are often missed. A recent systematic review on self-management urges the need for a specific aspect and characteristic of self-management interventions: iterative interactions between participants and health-care professionals competent in using behavior change practices to elicit participants’ motivation, confidence, and competence to develop skills to better manage their disease. A recent review of self-care intervention in chronic disease states that the major deficits found in self-care interventions included a lack of attention and/or innovation to the psychological consequences of chronic illness, technology, and behavior change techniques to help patients manage symptoms. There is a need for exploration of mechanisms to explain the relationships between both anxiety and depression, and adherence to treatment in COPD. The latter is particularly appropriate for pulmonary rehabilitation, for which greater adherence is needed. This report aims to introduce basic aspects of behavior change and a proposed roadmap to introduce behavior change into pulmonary rehabilitation and chronic care programs.

Purpose: The airway defense mechanism of cough is essential for human survival. Recognition is growing about the distinct role of speech-language pathologists in the nonpharmacological management of various cough disorders. This clinical focus article aims to deliver relevant education about normal and pathological cough to strengthen existing clinical knowledge and skills. Conclusions: The neuronal pathways underlying normal cough function are complex. Cough problems refer to either reduced or heightened cough stemming from various disease processes, and both clinical presentations have detrimental consequences. Current evidence supports that patients who suffer from cough dysfunction benefit from nonpharmacological interventions offered via speech therapy as an adjunct to medical treatments. Speech therapy strategies apply the higher cognitive components of cough by focusing on the deliberate modification and coordination of respiration. Future research priorities are positioned toward improving clinical outcomes for cough disorders.

Background Health care professionals working in intensive care units report a high degree of burnout, but this topic has not been extensively studied from an interdisciplinary perspective. Objective To characterize experiences of burnout among members of interprofessional intensive care unit teams and identify possible contributing factors. Methods This qualitative study involved interviews of registered nurses, respiratory therapists, physicians, pharmacists, and a personal care assistant working in multiple intensive care units of a single academic medical center to assess work stressors. Results Team composition was a factor in burnout, particularly when nonphysician team members felt that their opinions were not valued despite the institution’s emphasis on a multidisciplinary team-based model of care. This was especially true when roles were not well defined at the outset of a code situation. Members of nearly all disciplines stated that there was not enough time in a day to complete all the required tasks. Conclusions Multiple factors contribute to work-related stress and burnout across different professions in the intensive care unit. Improved communication and increased receptivity to diverse opinions among members of the multidisciplinary team may help reduce stress.

BACKGROUND: Pulmonary rehabilitation is an effective treatment for patients with COPD, but patient uptake and adherence to the current offering of center-based pulmonary rehabilitation is modest due to transportation, access, poverty, and frailty, and even more so in the context of the COVID pandemic. Home-based options have been proposed and were found noninferior to center-based rehabilitation; however, there is a lack of home-based programs, and more understanding is needed. We aimed to test the feasibility, uptake, and adherence to a home-based program for COPD rehabilitation with health coaching. METHODS: We conducted a randomized trial with a wait-list controlled design to evaluate the effects of a home-based program with health coaching on breathlessness in subjects with moderate to severe COPD unable to attend the regular pulmonary rehabilitation program. The 8-week intervention consisted of video-guided exercises to be done 6 times a week and captured with a computer tablet. Health coaching was done weekly over the telephone to review subject activity and symptoms and to provide an opportunity for the subject to define their weekly goals. The primary outcomes were uptake, adherence, and Chronic Respiratory Questionnaire (CRQ) Dyspnea Domain. Secondary outcomes were self-management abilities and CRQ Emotions-Mastery-Fatigue. RESULTS: 154 subjects with moderate to severe COPD were randomized. Subject adherence was 86% to the proposed 6-times a week exercise routine. There ( P = .062) was no significant difference in breathlessness (CRQ dyspnea). There was a significant improvement in self-management abilities ( P < .001). The results of the qualitative interviews showed high levels of acceptability of the program. CONCLUSIONS: The tested home-based rehabilitation program with health coaching was feasible, highly acceptable, showed a high degree of adherence, and improved self-management abilities. This study offers seminal information for home-based rehabilitation programs to design alternative options of rehabilitation to individuals with COPD that cannot attend to the well-established center-based pulmonary rehabilitation.

AbstractBackgroundResilience represents the capacity to adapt to adversity. Resilience can improve following behavioral interventions. We examined lung transplant candidates’ resilience as a novel predictor using the Connor‐Davidson Resilience Scale (RISC‐10).MethodsWaitlisted candidates at six centers were mailed questionnaires from 9/16/2015 to 10/1/2019. Follow‐up surveys were collected annually and post‐transplant. Outcomes were recorded through February 17, 2020. Primary outcome was pre‐transplant death/delisting. Analyses included t test or chi‐square for group comparisons, Pearson's correlation coefficients for strength of relationships, and Cox proportional‐hazard models to evaluate associations with outcomes, adjusting for age, sex, and mood.ResultsParticipation was 55.3% (N = 199). Baseline RISC‐10 averaged 32.0 ± 5.6 and did not differ by demographics, primary transplant diagnosis, or disease severity markers. RISC‐10 did not correlate to the commonly utilized Psychosocial Assessment of Candidates for Transplant [PACT] or Stanford Integrated Psychosocial Assessment for Transplantation [SIPAT] tools. Scores < 26.3 (representing > 1 standard deviation below population average) occurred in 16% and were associated with pre‐transplant death or delisting, adjusted Hazard Ratio of 2.60 (95% Confidence Interval 1.23‐5.77; P = .01).ConclusionOne in six lung candidates had low resilience, predicting increased pre‐transplant death/delisting. RISC‐10 did not correlate with PACT or SIPAT; resilience may represent a novel risk factor.
