Remote endpoints for clinical trials in cystic fibrosis: Report from the U.S. CF foundation remote endpoints task force.

The COVID-19 pandemic necessitated a rapid shift in clinical research to perform virtual visits and remote endpoint assessments, providing a key opportunity to optimize the use of remote endpoints for clinical trials in cystic fibrosis. The use of remote endpoints could allow more diverse participation in clinical trials while minimizing participant burden but must be robustly evaluated to ensure adequate performance and feasibility. In response, the Cystic Fibrosis Foundation convened the Remote Endpoint Task Force (Supplemental Table 1), a multidisciplinary group of CF researchers with remote endpoint expertise and community members tasked to better understand the current and future use of remote endpoints for clinical research. Here, we describe the current use of remote endpoints in CF clinical research, address key unanswered questions regarding their use and feasibility, and discuss the next steps to determine clinical trial readiness.

An emotional journey: caregiver experiences with gastrostomy tube decision-making for children with cystic fibrosis.

BACKGROUND: Nutritional challenges are common in early CF care and stressful for caregivers of children with CF (cwCF) to navigate. Gastrostomy tube (G-tube) placement can improve weight gain, however the decision to proceed with placement is personalized and preference-sensitive. Little is known about the experiences of caregivers of cwCF and the G-tube decision-making process. OBJECTIVES: The present study used a qualitative approach to explore the perceptions and experiences of caregivers of cwCF with G-tube introductions and recommendations, as well as factors influencing G-tube decision-making. METHODS: Caregivers of cwCF aged ≤ 10 years completed audio-taped, semi-structured interviews describing their experiences with G-tube placement discussions. Interviews were transcribed and two independent researchers coded the transcripts and conducted content and thematic analysis using an inductive approach. RESULTS: Participants included 43 caregivers, 84 % were mothers (36/43). CwCF had a mean age of 4 years (SD=2.6), 84 % were White (36/43), and 60 % reported weights below <50th percentile (26/43). All caregivers knew about G-tubes, 44 % (19/43) were recommended a G-tube and 35 % (15/43) had a G-tube placed. Major findings included descriptions of the stages of G-tube decision-making from a heads up, to the game plan, to making a first difficult decision and finally living with the decision to pursue G-tube placement. CONCLUSION: G-tube decision-making is an emotional and personalized journey for caregivers of cwCF. Efforts to explore the values and priorities of caregivers is imperative to supporting families making difficult decisions in CF care.

Factors Associated With Non-vaccination for Influenza Among Patients With CKD: Findings From the Chronic Renal Insufficiency Cohort (CRIC) Study.

RATIONALE & OBJECTIVE: Vaccination for influenza is strongly recommended for people with chronic kidney disease (CKD) due to their immunocompromised state. Identifying risk factors for not receiving an influenza vaccine (non-vaccination) could inform strategies for improving vaccine uptake in this high-risk population. STUDY DESIGN: Longitudinal observational study. SETTING & PARTICIPANTS: 3,692 Chronic Renal Insufficiency Cohort Study (CRIC) participants. EXPOSURE: Demographic factors, social determinants of health, clinical conditions, and health behaviors. OUTCOME: Influenza non-vaccination, which was assessed based on a receipt of influenza vaccine ascertained during annual clinic visits in a subset of participants who were under nephrology care. ANALYTICAL APPROACH: Mixed-effects Poisson models to estimate adjusted prevalence ratios (APRs). RESULTS: Between 2009 and 2020, the pooled mean vaccine uptake was 72% (mean age, 66 years; 44% female; 44% Black race). In multivariable models, factors significantly associated with influenza non-vaccination were younger age (APR, 2.16 [95% CI, 1.85-2.52] for<50 vs≥75 years), Black race (APR, 1.58 [95% CI, 1.43-1.75] vs White race), lower education (APR, 1.20 [95% CI, 1.04-1.39 for less than high school vs college graduate]), lower annual household income (APR, 1.26 [95% CI, 1.06-1.49] for <$20,000 vs >$100,000), formerly married status (APR, 1.22 [95% CI, 1.09-1.35] vs currently married), and nonemployed status (APR, 1.13 [95% CI, 1.02-1.24] vs employed). In contrast, participants with diabetes (APR, 0.80 [95% CI, 0.73-0.87] vs no diabetes), chronic obstructive pulmonary disease (COPD) (APR, 0.80 [95% CI, 0.70-0.92] vs no COPD), end-stage kidney disease (APR, 0.64 [0.56 to 0.76] vs estimated glomerular filtration rate≥60mL/min/1.73m2), frailty (APR, 0.86 [95% CI, 0.74-0.99] vs no frailty), and ideal physical activity (APR, 0.90 [95% CI, 0.82-0.99] vs. physically inactive) were less likely to have non-vaccination status. LIMITATIONS: Possible residual confounding. CONCLUSIONS: Among adults with CKD receiving nephrology care, younger adults, Black individuals, and those with adverse social determinants of health were more likely to have the influenza non-vaccination status. Strategies are needed to address these disparities and reduce barriers to vaccination. PLAIN-LANGUAGE SUMMARY: Identifying risk factors for not receiving an influenza vaccine ("non-vaccination") in people living with kidney disease, who are at risk of influenza and its complications, could inform strategies for improving vaccine uptake. In this study, we examined whether demographic factors, social determinants of health, and clinical conditions were linked to the status of not receiving an influenza vaccine among people living with kidney disease and receiving nephrology care. We found that younger adults, Black individuals, and those with adverse social determinants of health were more likely to not receive the influenza vaccine. These findings suggest the need for strategies to address these disparities and reduce barriers to vaccination in people living with kidney disease.

Asthma routinization, family asthma management, caregiver depressive symptoms, and medication adherence in Head Start preschool children.

Introduction: Medication adherence is suboptimal in childhood asthma. Children rely on caregivers to manage medication administration. It is important to detect families who are at risk for poor adherence or to identify potential areas that can assist families with better adherence to asthma medications in order to improve asthma outcomes. We investigated the association between asthma routines, family asthma management knowledge and skills, and caregiver depressive symptoms with daily controller medication adherence among Head Start preschool children in Baltimore City. Methods: Our study included 256 low-income urban preschool children who were prescribed a daily controller medication. Asthma routinization (by the Asthma Routines Questionnaire), family asthma management [by the Family Asthma Management System Scale (FAMSS)], and caregiver depressive symptoms (by the Center for Epidemiological Studies - Depression) were assessed at baseline. The medication possession ratio (MPR) to measure adherence to daily controller medications was calculated at baseline and 12 months from pharmacy fill records. Multiple regression models evaluated the relationship between asthma routinization, the FAMSS, the CES-D, and MPR. Results: Results indicated that only 7% of families had an MPR above 80% at baseline, and 24% of caregivers had clinically significant depressive symptoms. Higher asthma medication routines were associated with higher MPR at baseline (b = 0.05, p = 0.03). Higher family asthma management was associated with higher MPR at both baseline (b = 0.04, p < 0.01) and 12 months (b = 0.05, p < 0.01). Discussion: Our findings highlight the importance of family asthma management and maintaining medication routines over time to improve asthma controller medication adherence.

Medication adherence in youths with CKD: habits for success.

BACKGROUND: Poor adherence habits are key contributors to nonadherence but there are few clinically feasible methods for evaluating adherence habits, particularly for youths with chronic kidney disease (CKD). This study investigated how participants' qualitative responses to three interview questions about adherence habits mapped to primary principles of habit formation and objectively measured medication adherence in youths with CKD. METHODS: Participants (ages 11-21 years) were recruited from a pediatric nephrology clinic as part of a larger study. Participants' daily objective antihypertensive medication adherence was measured with an electronic pill bottle over a 4-week baseline period. Qualitative interviews about adherence habits and routines were conducted with a subset of participants (N = 18). RESULTS: Clear qualitative differences emerged in how participants with high-medium adherence (80-100%) discussed adherence habits compared to participants with low adherence (0-79%). Participants with high-medium adherence discussed situational cues for taking medicine, including locations that cue adherence, step-by-step events leading up to taking medicine, and people who cue adherence. Participants with high-medium adherence regularly described taking medicine as "automatic," "second nature," and a "habit." Participants with low adherence rarely discussed these habit features nor did they explicitly acknowledge currently missing doses. Participants with low adherence tended to discuss challenges with organization and routines for taking medicine. CONCLUSIONS: Evaluating patient responses to questions about adherence habits may uncover challenges with adherence habit formation, provide direction for habit-strengthening intervention focused on developing automatic cues for taking medication, and support adherence successes for youths with CKD.

Partners in research: The success with therapies research consortium and the CF community unite to improve self-management.

BACKGROUND: The daily treatment regimen for an individual with cystic fibrosis (CF) can take more than 2 h to complete, and chronic treatment adherence rates are low. Developing partnerships between CF clinical researchers and the CF community is essential in developing acceptable, feasible, and effective strategies to improve self-management and adherence. METHODS: The Success with Therapies Research Consortium (STRC) was formed as a multi-center US collaborative to conduct rigorous research studies of adherence to CF treatments. A multidisciplinary team of researchers from 15 sites, collaborating with members of the CF community, is charged with developing, implementing, and disseminating real-world, patient-centered interventions for people living with CF. RESULTS: Since 2014, the STRC has conducted 8 studies. The CF community, people with CF (pwCF), and caregivers have come to serve in multiple valuable capacities on the STRC, including as members of the Steering Committee and Co-Principal Investigators. Additionally, while people with CF are irreplaceable participants in STRC studies, their influence, and that of their families and healthcare professionals, extends beyond the traditional research participant role. CONCLUSIONS: Engaging broadly with the CF community is the optimal model for developing interventions to support those living with CF in sustaining daily care. Input and direct involvement from people with CF, their families, and their caregivers has enabled the STRC to advance its mission through innovative clinical research approaches.

Early life growth trajectories in cystic fibrosis are associated with lung function at age six.

BACKGROUND: Higher growth percentiles are associated with more favorable lung function in cystic fibrosis (CF), prompting the creation of CF Foundation (CFF) nutritional guidelines. OBJECTIVES: To describe early childhood growth trajectories within CF, to determine if growth trajectories are associated with differences in lung function at age six, and to identify factors that differ between trajectory groups. METHODS: Retrospective cohort study of children diagnosed with CF and born 2000-2011 using the US CFF Patient Registry. Annualized growth parameters prior to age six were included in group-based trajectory modeling to identify unique early life growth trajectories. FEV1 percent predicted (FEV1pp) at age six was compared between trajectory groups using linear regression. Factors associated with group membership were identified using multinomial logistic regression. RESULTS: 6,809 children met inclusion criteria. Six discrete growth trajectories were identified, including three groups that began with growth parameters >50th percentile, termed: "always high", "gradual decliner", "rapid decliner", and three which began with growth parameters <50th percentile, termed: "rapid riser", "gradual riser", "always low". FEV1pp at age six was highest for the Always High trajectory. The Always Low trajectory was nearly 10% lower than the Always High trajectory. Sex, ethnicity, newborn screening and pancreatic function were associated with trajectory class membership. CONCLUSIONS: Distinct early life growth trajectories were identified within CF. Trajectories that met CFF nutritional guideline recommendations were associated with higher FEV1pp at age six. CF care teams should continue to partner with families to encourage interventions to support optimal growth to improve lung function in CF.

Discontinuation versus continuation of hypertonic saline or dornase alfa in modulator treated people with cystic fibrosis (SIMPLIFY): results from two parallel, multicentre, open-label, randomised, controlled, non-inferiority trials.

BACKGROUND: Reducing treatment burden is a priority for people with cystic fibrosis, whose health has benefited from using new modulators that substantially increase CFTR protein function. The SIMPLIFY study aimed to assess the effects of discontinuing nebulised hypertonic saline or dornase alfa in individuals using the CFTR modulator elexacaftor plus tezacaftor plus ivacaftor (ETI). METHODS: The SIMPLIFY study included two parallel, multicentre, open-label, randomised, controlled, non-inferiority trials at 80 participating clinics across the USA in the Cystic Fibrosis Therapeutics Development Network. We included individuals with cystic fibrosis aged 12-17 years with percent predicted FEV1 (ppFEV1) of 70% or more, or those aged 18 years or older with ppFEV1 of 60% or more, if they had been taking ETI and either (or both) mucoactive therapies (≥3% hypertonic saline or dornase alfa) for at least 90 days before screening. Participants on both hypertonic saline and dornase alfa were randomly assigned to one of the two trials, and those on a single therapy were assigned to the applicable trial. All participants were then randomly assigned 1:1 to continue or discontinue therapy for 6 weeks using permuted blocks of varying size, stratified by baseline ppFEV1 (week 0; ≥90% or <90%), single or concurrent use of hypertonic saline and dornase alfa, previous SIMPLIFY study participation (yes or no), and age (≥18 or <18 years). For participants randomly assigned to continue their therapy during a given trial, this therapy was instructed to be taken at least once daily according to each participant's pre-existing, clinically prescribed regimen. Hypertonic saline concentration was required to be at least 3%. The primary objective for each trial was to determine whether discontinuing was non-inferior to continuing, measured by the 6-week change in ppFEV1 in the per-protocol population. We established a non-inferiority margin of -3% for the difference between groups in the 6-week change in ppFEV1. Safety outcomes were analysed in the intention-to-treat population. This study is registered with ClinicalTrials.gov, NCT04378153. FINDINGS: From Aug 25, 2020, to May 25, 2022, a total of 672 unique participants were screened for eligibility for one or both trials, resulting in 847 total random assignments across both trials with 594 unique participants. 370 participants were randomly assigned in the hypertonic saline trial and 477 in the dornase alfa trial. Participants across both trials had an average ppFEV1 of 96·9%. Discontinuing treatment was non-inferior to continuing treatment with respect to the absolute 6-week change in ppFEV1 in both the hypertonic saline trial (-0·19% [95% CI -0·85 to 0·48] in the discontinuation group [n=133] vs 0·14% [-0·51 to 0·78] in the continuation group [n=140]; between-group difference -0·32% [-1·25 to 0·60]) and dornase alfa trial (0·18% [-0·38 to 0·74] in the discontinuation group [n=199] vs -0·16% [-0·73 to 0·41] in the continuation group [n=193]; between-group difference 0·35% [-0·45 to 1·14]), with consistent results in the intention-to-treat populations. In the hypertonic saline trial, 64 (35%) of 184 in the discontinuation group versus 44 (24%) of 186 participants in the continuation group and, in the dornase alfa trial, 89 (37%) of 240 in the discontinuation group versus 55 (23%) of 237 in the continuation group had at least one adverse event. INTERPRETATION: In individuals with cystic fibrosis on ETI with relatively well preserved pulmonary function, discontinuing daily hypertonic saline or dornase alfa for 6 weeks did not result in clinically meaningful differences in pulmonary function when compared with continuing treatment.

Clinician attitudes and practices on pregnancy planning and care in cystic fibrosis.

BACKGROUND: People with cystic fibrosis (CF) are living longer and healthier lives as a result of cystic fibrosis transmembrane conductance regulator (CFTR) modulator therapies, and are pursuing pregnancy. As the number of pregnancies in CF continue to increase, clinician attitudes and practices regarding care of pregnant people with CF remain largely unknown. OBJECTIVE: To evaluate the current attitudes and practices of CF clinicians regarding pregnancy planning and care in CF. METHODS: We conducted a national survey investigating practice patterns related to pregnancy care in CF. We used descriptive statistics to summarize responses and paired t-tests to compare population means. RESULTS: A total of 93 clinicians completed the survey. Eighty-six percent of respondents believed family planning and pregnancy discussions should start before the age of 21 years, of which 67% believed these discussions should occur prior to age 18 years. Our results demonstrate variability in CF clinician comfort and management of various aspects of pregnancy care in CF including 1) potential complications of pregnancy 2) continuation of chronic CF therapies 3) continuation of CFTR modulators during pregnancy and lactation, and 4) approach to treatment of pulmonary exacerbation during pregnancy. CONCLUSIONS: As more people with CF pursue pregnancy in the era of CFTR modulators, CF providers should be initiating discussions surrounding pregnancy early and often. Establishing best practices in the management of pregnancy in CF, expanding peri­pregnancy expertise within the CF community, and future studies investigating the maternal-fetal effects of CF therapies are needed.

Self-Determination Theory and Preventive Medication Adherence: Motivational Considerations to Support Historically Marginalized Adolescents With Asthma.

INTRODUCTION: Using self-determination theory, we explored relationships between autonomous motivation (AM) and perceived competence (PC) with previously validated measures of motivation and adolescent-reported asthma medication adherence. METHOD: Data were from adolescents (n = 260) enrolled in the School-Based Asthma Care for Teens study and taking preventive medication at baseline. Eligible adolescents (aged 12-16 years) had physician-diagnosed persistent asthma or poor control. RESULTS: Adolescents taking daily preventive medicine reported higher AM and PC for adherence, whereas adolescents likely to miss ≥1 dose in the next 2 weeks had lower AM and PC. Adolescents taking medicines as prescribed, with plans to continue, and those feeling able to follow provider care plans, had higher AM and PC. Findings remained significant in regressions with control variables. DISCUSSION: Many factors interfere with adolescent medication-taking. Clinicians' efforts to build AM and PC with patients and caregivers may be key to promoting adherence in this group.

Agreement between attended home and ambulatory blood pressure measurements in adolescents with chronic kidney disease.

BACKGROUND: This study aimed to compare attended home blood pressure (BP) measurements (HBPM) with ambulatory BP monitor (ABPM) readings and examine if level of agreement between measurement modalities differs overall and by subgroup. METHODS: This was a secondary analysis of data from a 2-year, multicenter observational study of children 11-19 years (mean 15, SD = 2.7) with chronic kidney disease. Participants had 3 standardized resting oscillometric home BPs taken by staff followed by 24-h ABPM within 2 weeks of home BP. BP indices (measured BP/95%ile BP) were calculated for mean triplicate attended HBPM and mean ABPM measurements. Paired HBPM and ABPM measurements taken during any of 5 study visits were compared using linear regression with robust standard errors. Generalized estimating equation-based logistic regression determined sensitivity, specificity, negative, and positive predictive values with ABPM as the gold standard. Analyses were conducted for the group overall and by subgroup. RESULTS: A total of 103 participants contributed 251 paired measurements. Indexed systolic BP did not differ between HBPM and daytime APBM (mean difference - 0.002; 95% CI: - 0.006, 0.003); the difference in indexed diastolic BP was minimal (mean difference - 0.033; 95% CI: - 0.040, - 0.025). Overall agreement between HBPM and 24-h ABPM in identifying abnormal BP was high (81.8%). HBPM had higher sensitivity (87.5%) than specificity (77.4%) and greater negative (89.8%) than positive (73.3%) predictive value, and findings were consistent in subgroups. CONCLUSIONS: Attended HBPM may be reasonable for monitoring BP when ABPM is unavailable. The greater accessibility and feasibility of attended HBPM may potentially help improve BP control among at-risk youth. A higher resolution version of the Graphical abstract is available as Supplementary information.

Clinical outcomes in cystic fibrosis at 6 years of age with tricare insurance coverage.

Health insurance coverage is associated with outcomes in cystic fibrosis (CF). A fraction of individuals in the United States are covered through Tricare, a federally funded program for military members and their dependents. The role of Tricare on CF health outcomes is unknown. Using a retrospective CF Foundation Patient Registry cohort born 2000-2011, insurance status was defined as any Tricare (n = 328) with reference groups of always private (n = 3,455) and exclusively public (n = 2,669) during the first 6 years of life. Subjects with Tricare coverage attended more CF care centers and lived in more zip codes by age 6 than their counterparts. BMI did not differ between groups. Subjects with Tricare had a higher FEV1 at age 6 compared to those with always public insurance. Overall, outcomes for those with Tricare insurance appeared more similar to those with always private insurance. Future research should consider treating Tricare coverage similar to private insurance.

Association between insurance variability and early lung function in children with cystic fibrosis.

BACKGROUND: Lower socioeconomic status (SES) has consistently been associated with poorer outcomes in individuals with cystic fibrosis (CF). Previous studies have compared outcomes for children with and without private insurance coverage, however the potential role of changes in insurance status on early health outcomes in children with CF remains unknown. OBJECTIVES: To describe the variability in insurance status in early childhood and to evaluate whether insurance variability was associated with poorer outcomes at age 6. METHODS: Retrospective observational study using the Cystic Fibrosis Foundation Patient Registry. Insurance status was defined as: always private (including Tricare), exclusively public, or intermittent private insurance (private insurance and exclusively public insurance in separate years) during the first 6 years of life. Outcomes at age 6 included body mass index (BMI) and FEV1 percent predicted (maxFEV1pp). RESULTS: From a 2000-2011 birth cohort (n = 8,109), 42.3% always had private insurance, 30.0% had exclusively public insurance, and 27.6% had intermittent private insurance. BMI percentiles did not differ between groups; however, children with intermittent private insurance and exclusively public insurance had a 3.3% and 6.6% lower maxFEV1pp at age 6, respectively, compared to those with always private insurance. CONCLUSIONS: A substantial proportion of young children in a modern CF cohort have public or intermittent private insurance coverage. While public insurance has been associated with poorer health outcomes in CF, variability in health insurance coverage may also be associated with an intermediate risk of disparities in lung function as early as age 6.

Family management of asthma in Head Start preschool children.

BACKGROUND: Urban minority preschool children are disproportionately affected by asthma with increased asthma morbidity and mortality. It is important to understand how families manage asthma in preschool children to improve asthma control. OBJECTIVE: To evaluate family asthma management and asthma outcomes among a low-income urban minority population of Head Start preschool children. METHODS: The family asthma management system scale (FAMSS) evaluates how families manage a child's asthma. A total of 388 caregivers completed the FAMSS at baseline. Asthma outcomes were evaluated at baseline and prospectively at 6 months, including asthma control (based on the Test for Respiratory and Asthma Control in Kids), courses of oral corticosteroids (OCSs) required, and caregiver health-related quality of life (Pediatric Asthma Caregiver's Quality of Life Questionnaire [PACQLQ]). Multiple regression models evaluated the relationship between the FAMSS total score, FAMSS subscales, and asthma outcomes. RESULTS: Higher FAMSS total scores were associated with fewer courses of OCSs required (b = -0.23, P < .01) and higher PACQLQ scores (b = 0.07, P < .05). At baseline, higher integration subscale scores (b = -0.19, P < .05) were associated with fewer courses of OCSs required, and higher family response scores were associates with higher PACQLQ scores (b = 0.06, P < .05). Nevertheless, higher collaboration scores were associated with lower PACQLQ at baseline (b = -0.06, P < .05) and 6 months (b = -0.07, P < .05). CONCLUSION: Among this population of low-income minority preschool children, understanding how a family manages their child's asthma may help identify gaps for education to possibly improve caregiver asthma-related quality of life and reduce courses of OCSs.

Effect of the School-Based Asthma Care for Teens (SB-ACT) program on asthma morbidity: a 3-arm randomized controlled trial.

Urban adolescents with asthma often have inadequate preventive care. We tested the effectiveness of the School-Based Asthma Care for Teens (SB-ACT) program on asthma morbidity and preventive medication adherence.Methods:Subjects/Setting- 12-16yr olds with persistent asthma in Rochester, NY schools. Design- 3-group randomized trial (2014-2019). SB-ACT Intervention- Two core components: 1) Directly observed therapy (DOT) of preventive asthma medications, provided in school for at least 6-8 weeks for the teen to learn proper technique and experience the benefits of daily preventive therapy; 2) 4-6 weeks later, 3 sessions of motivational interviewing (MI) to discuss potential benefits from DOT and enhance motivation to take medication independently. We included 2 comparison groups: 1) DOT-only for 6-8wks, and 2) asthma education (AE) attention control. Masked follow-up assessments were conducted at 3, 5, and 7mos. Outcomes- Mean number of symptom-free days (SFDs)/2 weeks and medication adherence. Analyses- Modified intention-to-treat repeated measures analysis.Results: We enrolled 430 teens (56% Black, 32% Hispanic, 85% Medicaid). There were no group differences at baseline. We found no difference in SFDs at any follow-up timepoint. More teens in the SB-ACT and DOT-only groups reported having a preventive asthma medication at each follow-up (p<.001), and almost daily adherence at 3 and 5-months (p<.001, p=.003) compared to AE. By 7 months there were no significant differences between groups in adherence (p=.49).Conclusion: SB-ACT improved preventive medication availability and short-term adherence but did not impact asthma symptoms. Further work is needed to create developmentally appropriate and effective interventions for this group.

Enhancing Recruitment and Retention of Minority Populations for Clinical Research in Pulmonary, Critical Care, and Sleep Medicine: An Official American Thoracic Society Research Statement.

Background: Well-designed clinical research needs to obtain information that is applicable to the general population. However, most current studies fail to include substantial cohorts of racial/ethnic minority populations. Such underrepresentation may lead to delayed diagnosis or misdiagnosis of disease, wide application of approved interventions without appropriate knowledge of their usefulness in certain populations, and development of recommendations that are not broadly applicable.Goals: To develop best practices for recruitment and retention of racial/ethnic minorities for clinical research in pulmonary, critical care, and sleep medicine.Methods: The American Thoracic Society convened a workshop in May of 2019. This included an international interprofessional group from academia, industry, the NIH, and the U.S. Food and Drug Administration, with expertise ranging from clinical and biomedical research to community-based participatory research methods and patient advocacy. Workshop participants addressed historical and current mistrust of scientific research, systemic bias, and social and structural barriers to minority participation in clinical research. A literature search of PubMed and Google Scholar was performed to support conclusions. The search was not a systematic review of the literature.Results: Barriers at the individual, interpersonal, institutional, and federal/policy levels were identified as limiting to minority participation in clinical research. Through the use of a multilevel framework, workshop participants proposed evidence-based solutions to the identified barriers.Conclusions: To date, minority participation in clinical research is not representative of the U.S. and global populations. This American Thoracic Society research statement identifies potential evidence-based solutions by applying a multilevel framework that is anchored in community engagement methods and patient advocacy.

Sex differences in treatment patterns in cystic fibrosis pulmonary exacerbations.

BACKGROUND: Females with cystic fibrosis (CF) have been shown to have worse pulmonary exacerbation (PEx) related outcomes compared to males. However, it is unknown if sex differences in treatment patterns are contributing to these outcomes. Thus, we sought to explore sex differences in treatment patterns in the Standardized Treatment of Pulmonary Exacerbations (STOP) cohort. METHODS: Data for 220 participants from the STOP cohort were analyzed. Multivariable regression models were used to assess if female sex was associated with duration of treatment with IV antibiotics and inpatient length of stay. Secondary outcomes included antibiotic selection, adjunctive therapies, mean FEV1pp and CFRSD-CRISS respiratory symptom scores at the four study assessments. RESULTS: In our adjusted model, the average number of IV antibiotic treatment days was 13% higher in females compared to males (IRR 1.13, 95% CI=1.02,1.25; p=0.02). We found no sex differences in inpatient length of stay, number of IV antibiotics, antibiotic selection or initiation of adjunctive therapies. Overall, females had higher CFRSD-CRISS scores at the end of IV therapy indicating worse symptom severity (23.6 for females vs. 18.5 for males, p=0.03). CONCLUSIONS: Despite females having a longer treatment duration, our findings demonstrate that males and females are receiving similar treatments which suggest that the outcome disparities in females with CF may not be due to failure to provide the same level of care. Further research dedicated to sex differences in CF is necessary to understand why clinical outcomes differ between males and females.

Balancing Demands: Determinants of Burnout Reported by Fellows in Pulmonary and Critical Care Medicine.

Background: Burnout is common among physicians who care for critically ill patients and is known to contribute to worse patient outcomes. Fellows training in pulmonary and critical care medicine (PCCM) have risk factors that make them susceptible to burnout; for example, clinical environments that require increased intellectual and emotional demands with long hours. The Accreditation Council for Graduate Medical Education has recognized the increasing importance of trainee burnout and encourages training programs to address burnout. Objective: To assess factors related to training and practice that posed a threat to the well-being among fellows training in PCCM and to obtain suggestions regarding how programs can improve fellow well-being. Methods: We conducted a qualitative content analysis of data collected from a prior cross-sectional electronic survey with free-response questions of fellows enrolled in pulmonary, PCCM, and critical care medicine training programs in the United States. Fellows were asked what factors posed a threat to their well-being and what changes their training program could implement. Responses were qualitatively coded and categorized into themes using thematic analysis. Results: A total of 427 fellows (44% of survey respondents) completed at least one free-response question. The majority of respondents (60%) identified as male and white/non-Hispanic (59%). The threats to well-being and burnout were grouped into five themes: clinical burden, individual factors, team culture, limited autonomy, and program resources. Clinical burden was the most common threat discussed by fellows. Fellows highlighted factors contributing to burnout that specifically pertained to trainees including challenging interpersonal relationships with attending physicians and limited protected educational time. Fellows proposed solutions addressing clinical care, changes at the program or institution level, and organizational culture changes to improve well-being. Conclusion: This study provides insight into factors fellows report as contributors to burnout and decreased well-being in addition to investigating fellow-driven solutions toward improving well-being. These solutions may help pulmonary, PCCM, and critical care medicine program directors better address fellow well-being in the future.

The Patient Reported Outcomes as a Clinical Tool (PROACT) Pilot Study: What Can be Gained by Sharing Computerized Patient-Reported Mental Health and Substance Use Symptoms with Providers in HIV Care?

Substance use and mental health (SU/MH) disorders are insufficiently recognized in HIV care. We examined whether conveying SU/MH screening results to patients and providers increased SU/MH discussions and action plans. Intervention participants completed a computerized patient-reported questionnaire before their HIV visit; screened positive on ≥ 1 measure: depression, anxiety, PTSD symptoms, at-risk alcohol use, or drug use; and reviewed screening results to decide which to prioritize with their provider. Screening results and clinical recommendations were conveyed to providers via medical record. A historic control included patients with positive screens but no conveyance to patient or provider. The patient-provider encounter was audio-recorded, transcribed, and coded. For the overall sample (n = 70; 38 control, 32 intervention), mean age (SD) was 51.8 (10.3), 61.4% were male, and 82.9% were Black. Overall, 93.8% raised SU/MH in the intervention compared to 50.0% in the control (p < 0.001). Action plans were made for 40.0% of intervention and 10.5% of control encounters (p = 0.049). Conveying screening results with clinical recommendations increased SU/MH action plans, warranting further research on this intervention to address SU/MH needs.
