Perspectives of Black Adults Living with Chronic Obstructive Pulmonary Disease on Barriers to Cardiovascular Disease Prevention.

RATIONALE: Cardiovascular disease (CVD) is a leading cause of morbidity and mortality among individuals with chronic obstructive pulmonary disease (COPD). Black women with COPD are at elevated risk of CVD-related mortality compared to White women. CVD risk factors are undertreated in Black men and women. However, barriers to CVD prevention from the perspective of Black individuals living with COPD have not been previously identified. OBJECTIVE: To identify barriers and facilitators for CVD prevention among Black individuals living with COPD. METHODS: We conducted semi-structured interviews with Black participants living with COPD and attending clinics at two urban hospitals. Participants were included if they had physician confirmed COPD diagnosis and presence of CVD or CVD risk factors. Participants were interviewed until thematic saturation was reached, with additional interviews conducted to confirm saturation. Data were analyzed using thematic analysis, iteratively revising, and updating the codebook by consensus of the study team. Codes were grouped into categories, subthemes, and themes. Themes were organized using the social ecological framework into individual, interpersonal, health system, and societal levels. RESULTS: We interviewed 30 participants of mean age 67.8 ± 8.3 years; 17 (57%) were Black women and 13 (43%) were Black men. Individual-level themes were: living with COPD and resultant multimorbidity impacts CVD prevention (theme 1), and self-efficacy and advocacy impact care received (theme 2). At the interpersonal level: supportive relationships facilitate improved access to CVD prevention (theme 3). System level themes were: health systems are not designed to support patients with COPD and CVD (theme 4), and health systems do not deliver effective patient education (theme 5). At the societal level: structural barriers and racism prevent accessing care and adopting a healthy lifestyle (theme 6). CONCLUSIONS: We identified barriers to CVD prevention at all levels of the socio-ecological framework for Black individuals living with COPD. To maximize their impact, future interventions to prevent CVD among individuals with COPD can use these findings to target barriers at multiple levels.

COPD and multimorbidity: recognising and addressing a syndemic occurrence.

Most patients with chronic obstructive pulmonary disease (COPD) have at least one additional, clinically relevant chronic disease. Those with the most severe airflow obstruction will die from respiratory failure, but most patients with COPD die from non-respiratory disorders, particularly cardiovascular diseases and cancer. As many chronic diseases have shared risk factors (eg, ageing, smoking, pollution, inactivity, and poverty), we argue that a shift from the current paradigm in which COPD is considered as a single disease with comorbidities, to one in which COPD is considered as part of a multimorbid state-with co-occurring diseases potentially sharing pathobiological mechanisms-is needed to advance disease prevention, diagnosis, and management. The term syndemics is used to describe the co-occurrence of diseases with shared mechanisms and risk factors, a novel concept that we propose helps to explain the clustering of certain morbidities in patients diagnosed with COPD. A syndemics approach to understanding COPD could have important clinical implications, in which the complex disease presentations in these patients are addressed through proactive diagnosis, assessment of severity, and integrated management of the COPD multimorbid state, with a patient-centred rather than a single-disease approach.

Disparities in Guideline Concordant Statin Treatment in Individuals With Chronic Obstructive Pulmonary Disease.

Rationale: Cardiovascular disease (CVD) affects the prognosis of patients with chronic obstructive pulmonary disease (COPD). Black women with COPD have a disproportionate risk of CVD-related mortality, yet disparities in CVD prevention in COPD are unknown. Objectives: We aimed to identify race-sex differences in the receipt of statin treatment for CVD prevention, and whether these differences were explained by factors influencing health care utilization in the REasons for Geographic And Racial Differences in Stroke (REGARDS) COPD study sub-cohort. Methods: We conducted a cross-sectional analysis among REGARDS Medicare beneficiaries with COPD. Our primary outcome was the presence of statin on in-home pill bottle review among individuals with an indication. Prevalence ratios (PR) for statin treatment among race-sex groups compared to White men were estimated using Poisson regression with robust variance. We then adjusted for covariates previously shown to impact health care utilization. Results: Of the 2032 members within the COPD sub-cohort with sufficient data, 1435 participants (19% Black women, 14% Black men, 28% White women, and 39% White men) had a statin indication. All race-sex groups were less likely to receive statins than White men in unadjusted models. After adjusting for covariates that influence health care utilization, Black women (PR 0.76, 95% confidence interval [CI] 0.67 to 0.86) and White women (PR 0.84 95% CI 0.76 to 0.91) remained less likely to be treated compared to White men. Conclusions: All race-sex groups were less likely to receive statin treatment in the REGARDS COPD sub-cohort compared to White men. This difference persisted in women after controlling for individual health care utilization factors, suggesting structural interventions are needed.

Validity and Reliability of the Fatigue Severity Scale in a Real-World Interstitial Lung Disease Cohort.

Rationale: Fatigue is a common and debilitating symptom for people living with interstitial lung disease (ILD). Studies on fatigue in ILD are limited, and little headway has been made toward developing interventions targeting the alleviation of fatigue. A barrier to progress is a lack of knowledge around the performance characteristics of a patient-reported outcome measure to assess fatigue in patients with ILD. Objectives: To assess the validity and reliability of the Fatigue Severity Scale (FSS) for measuring fatigue in a national cohort of patients with ILD. Methods: FSS scores and several anchors were measured in 1,881 patients from the Pulmonary Fibrosis Foundation Patient Registry. Anchors included the Short Form 6D Health Utility Index (SF-6D) score and a single vitality question from the SF-6D; the University of California, San Diego, Shortness of Breath Questionnaire; FVC; DlCO; and 6-minute-walk distance. Internal consistency reliability, concurrent validity, and known-groups validity were assessed. Structural validity was assessed using confirmatory factor analysis. Measurements and Main Results: The FSS demonstrated high internal consistency (Cronbach's α = 0.96). There were moderate to strong correlations between FSS score and patient-reported anchors (vitality question from the SF-6D [r = 0.55] and University of California, San Diego, Shortness of Breath Questionnaire total score [r = 0.70]) and weak correlations between FSS score and physiological measures (FVC [r = -0.24], percentage predicted DlCO [r = -0.23], and 6-minute-walk distance [r = -0.29]). Higher mean FSS scores, indicating greater fatigue, were observed among patients using supplemental oxygen, those prescribed steroids, and those with lower percentage predicted FVC and percentage predicted DlCO. The confirmatory factor analysis results suggest that the nine questions of the FSS reflect one dimension of fatigue. Conclusions: Fatigue is an important patient-centered outcome in ILD that is poorly correlated with physiological measures of disease severity, including lung function and walk distance. These findings further support the need for a reliable and valid measure of patient-reported fatigue in ILD. The FSS possesses acceptable performance characteristics for assessing fatigue and distinguishing different degrees of fatigue among patients with ILD.

Race and Sex Differences in Mortality in Individuals with Chronic Obstructive Pulmonary Disease.

Rationale: Despite differences in chronic obstructive pulmonary disease (COPD) comorbidities, race- and sex-based differences in all-cause mortality and cause-specific mortality are not well described. Objectives: To examine mortality differences in COPD by race-sex and underlying mechanisms. Methods: Medicare claims were used to identify COPD among REGARDS (Reasons for Geographic and Racial Differences in Stroke) cohort participants. Mortality rates were calculated using adjudicated causes of death. Hazard ratios (HRs) for mortality comparing race-sex groups were modeled with Cox proportional hazards regression. Results: In the 2,148-member COPD subcohort, 49% were women, and 34% were Black individuals; 1,326 deaths occurred over a median 7.5 years (interquartile range, 3.9-10.5 yr) follow-up. All-cause mortality per 1,000 person-years comparing Black versus White men was 101.1 (95% confidence interval [CI], 88.3-115.8) versus 93.9 (95% CI, 86.3-102.3; P = 0.99); comparing Black versus White women, all-cause mortality per 1,000 person-years was 74.2 (95% CI, 65.0-84.8) versus 70.6 (95% CI, 63.5-78.5; P = 0.99). Cardiovascular disease (CVD) was the leading cause-specific mortality among all race-sex groups. HR for CVD and chronic lung disease mortality were nonsignificant comparing Black versus White men. HR for CVD death was higher in Black compared with White women (HR, 1.44; 95% CI, 1.06-1.95), whereas chronic lung disease death was lower (HR, 0.44; 95% CI, 0.25-0.77). These differences were attributable to higher CVD risk factor burden among Black women. Conclusions: In the REGARDS COPD cohort, there were no race-sex differences in all-cause mortality. CVD was the most common cause of death for all race-sex groups with COPD. Black women with COPD had a higher risk of CVD-related mortality than White women. CVD comorbidity management, especially among Black individuals, may improve mortality outcomes.

Feasibility of a Novel Real-Time Provider Teaching Intervention in Acute Exacerbation of Chronic Obstructive Pulmonary Disease.

Background: It is not known whether an intervention using real-time provider teaching in acute exacerbation of chronic obstructive pulmonary disease (AECOPD) improves provider knowledge and/or patient outcomes. Objective: To pilot the combination of a novel, real-time provider teaching intervention delivered by subspecialists to Internal Medicine trainees with a traditional patient education and medication reconciliation (PEMR) intervention and to assess the impact of these interventions on provider knowledge regarding COPD and patient care. Methods: This was a single-center, nonrandomized, quality-improvement study. Patients admitted with AECOPD were prospectively identified between June 19 and November 20, 2019. Patients with asthma, lung cancer, or interstitial lung disease were excluded. The primary care team received a novel intervention featuring in-person, real-time teaching, covering Global Initiative on Chronic Obstructive Lung Disease COPD groups and management, including pulmonary rehabilitation referral. Providers completed a knowledge assessment before and after their real-time teaching session. Provider knowledge scores before and after teaching were compared using McNemar's test. Patients received a traditional PEMR intervention from a nurse practitioner and/or clinical pharmacist. A retrospective chart review was conducted for 50 historical control patients admitted with AECOPD to obtain preintervention rates of discharge on long-acting bronchodilators and referral to pulmonary rehabilitation. The proportions of patients discharged on long-acting bronchodilators and referred to pulmonary rehabilitation in the intervention group were compared with the preintervention historical control patients using chi-square testing. Results: Seventy-one providers caring for patients with AECOPD received real-time teaching. Postintervention, there was significant improvement in knowledge scores pertaining to Global Initiative on Chronic Obstructive Lung Disease groups and exacerbation risk (81% correct vs. 43% on pretest; P < 0.001) and guideline-directed treatment (83% correct vs. 28% on pretest; P < 0.001). Out of 44 eligible patients, 75% (n = 33 patients) received the PEMR intervention. Ninety percent of patients (n = 40 patients) were discharged on any long-acting inhaler, similar to the group of preintervention control subjects. Pulmonary rehabilitation referrals were made for 50% of patients (n = 22 patients) compared with 6% of preintervention control subjects (n = 3 patients; P < 0.001). Conclusion: In this single-center quality-improvement study, the combination of a novel, real-time provider teaching intervention and a traditional PEMR intervention improved provider knowledge and was associated with increased referrals to pulmonary rehabilitation.

Assessing mortality differences across acute respiratory failure management strategies in Covid-19.

PURPOSE: Prolonged observation could avoid invasive mechanical ventilation (IMV) and related risks in patients with Covid-19 acute respiratory failure (ARF) compared to initiating early IMV. We aimed to determine the association between ARF management strategy and in-hospital mortality. MATERIALS AND METHODS: Patients in the Weill Cornell Covid-19 registry who developed ARF between March 5 - March 25, 2020 were exposed to an early IMV strategy; between March 26 - April 1, 2020 to an intermediate strategy; and after April 2 to prolonged observation. Cox proportional hazards regression was used to model in-hospital mortality and test an interaction between ARF management strategy and modified sequential organ failure assessment (mSOFA). RESULTS: Among 632 patients with ARF, 24% of patients in the early IMV strategy died versus 28% in prolonged observation. At lower mSOFA, prolonged observation was associated with lower mortality compared to early IMV (at mSOFA = 0, HR 0.16 [95% CI 0.04-0.57]). Mortality risk increased in the prolonged observation strategy group with each point increase in mSOFA score (HR 1.29 [95% CI 1.10-1.51], p = 0.002). CONCLUSION: In Covid-19 ARF, prolonged observation was associated with a mortality benefit at lower mSOFA scores, and increased mortality at higher mSOFA scores compared to early IMV.

Characterizing COPD Symptom Variability in the Stable State Utilizing the Evaluating Respiratory Symptoms in COPD Instrument.

Rationale: It has been suggested that patients with chronic obstructive pulmonary disease (COPD) experience considerable daily respiratory symptom fluctuation. A standardized measure is needed to quantify and understand the implications of day-to-day symptom variability. Objectives: To compare standard deviation with other statistical measures of symptom variability and identify characteristics of individuals with higher symptom variability. Methods: Individuals in the SubPopulations and InteRmediate Outcome Measures In COPD Study (SPIROMICS) Exacerbations sub-study completed an Evaluating Respiratory Symptoms in COPD (E-RS) daily questionnaire. We calculated within-subject standard deviation (WS-SD) for each patient at week 0 and correlated this with measurements obtained 4 weeks later using Pearson's r and Bland Altman plots. Median WS-SD value dichotomized participants into higher versus lower variability groups. Association between WS-SD and exacerbation risk during 4 follow-up weeks was explored. Measurements and Main Results: Diary completion rates were sufficient in 140 (68%) of 205 sub-study participants. Reproducibility (r) of the WS-SD metric from baseline to week 4 was 0.32. Higher variability participants had higher St George's Respiratory Questionnaire (SGRQ) scores (47.3 ± 20.3 versus 39.6 ± 21.5, p=.04) than lower variability participants. Exploratory analyses found no relationship between symptom variability and health care resource utilization-defined exacerbations. Conclusions: WS-SD of the E-RS can be used as a measure of symptom variability in studies of patients with COPD. Patients with higher variability have worse health-related quality of life. WS-SD should be further validated as a measure to understand the implications of symptom variability.

Evolving Needs of Critical Care Trainees during the COVID-19 Pandemic: A Qualitative Study.

Background: Critical care trainees were integral in the coronavirus disease (COVID-19) pandemic response. Several perspective pieces have provided insight into the pandemic's impact on critical care training. Surveys of program directors and critical care trainees have focused on curricular impact. There is a lack of data from the trainee perspective on curricular enhancements, career development, and emotional and well-being needs to succeed in a critical care career in the ongoing COVID-19 pandemic. Objective: Our objective was to elicit perspectives from critical care trainees on their personal and professional needs as they continue to serve in the COVID-19 pandemic. Methods: This was a hypothesis-generating qualitative study. Individuals in a U.S. critical care training program during the COVID-19 pandemic participated in either focus groups or semistructured interviews. Interviews were conducted between July 2020 and March 2021 until data saturation was achieved. Audio recordings were professionally transcribed and analyzed using qualitative content analysis. A codebook was generated by two independent coders, with a third investigator reconciling codes when there were discrepancies. Themes and subthemes were identified from these codes. Results: Thirteen participants were interviewed. The major themes identified were as follows: 1) Curricular adaptation is necessary to address evolving changes in trainee needs; 2) COVID-19 impacted career development and highlighted that trainees need individualized help to meet their goals; 3) receiving social support at work from peers and leaders is vital for the sustained well-being of trainees; 4) fostering and maintaining a sense of meaning and humanity in one's work is important; and 5) trainees desire assistance and support to process their emotions and experiences. Conclusion: The needs expressed by critical care trainees are only partially captured in conceptual models of physician well-being. The need for multilevel workplace social networks and identifying meaning in one's work have been magnified in this pandemic. The themes discussing curricular gaps, career development needs, and skills to process work-related trauma are less well captured in preexisting conceptual models and point to areas where further research and intervention development are needed.

COVID-19-Related Circumstances for Hospital Readmissions: A Case Series From 2 New York City Hospitals.

OBJECTIVE: The aim of the study was to determine the main factors contributing to hospital readmissions and their potential preventability after a coronavirus disease 2019 (COVID-19) hospitalization at 2 New York City hospitals. METHODS: This was a retrospective study at 2 affiliated New York City hospitals located in the Upper East Side and Lower Manhattan neighborhoods. We performed case reviews using the Hospital Medicine Reengineering Network framework to determine potentially preventable readmissions among patients hospitalized for COVID-19 between March 3, 2020 (date of first case) and April 27, 2020, and readmitted to either of the 2 hospitals within 30 days of discharge. RESULTS: Among 53 readmissions after hospitalization for COVID-19, 44 (83%) were deemed not preventable and 9 (17%) were potentially preventable. Nonpreventable readmissions were mostly due to disease progression or complications of COVID-19 (37/44, 84%). Main factors contributing to potentially preventable readmissions were issues with initial disposition (5/9, 56%), premature discharge (3/9, 33%), and inappropriate readmission (1/9, 11%) for someone who likely did not require rehospitalization. CONCLUSIONS: Most readmissions after a COVID-19 hospitalization were not preventable and a consequence of the natural progression of the disease, specifically worsening dyspnea or hypoxemia. Some readmissions were potentially preventable, mostly because of issues with disposition that were directly related to challenges posed by the ongoing COVID-19 pandemic. Clinicians should be aware of challenges with disposition related to circumstances of the COVID-19 pandemic.

Eliminating Inappropriate Telemetry Monitoring: An Evidence-Based Implementation Guide.

In-hospital continuous electrocardiographic monitoring, commonly referred to as telemetry, has allowed for rapid recognition of life-threatening conditions, including complex arrhythmias and myocardial ischemia. However, inappropriate use can lead to unnecessary downstream testing from "false alarms," which in turn affects clinician efficiency and increases health care costs without benefiting patients. For these reasons, the Society of Hospital Medicine's Choosing Wisely campaign recommended use of a protocol-driven discontinuation of telemetry. The American Heart Association (AHA) developed a set of Practice Standards for the appropriate use of telemetry monitoring in 2004, which they updated in 2017. Unfortunately, the AHA Practice Standards have not been widely adopted-with as many as 43% of monitored patients lacking a recommended indication for monitoring. Thus, we created an overview discussing the safety and efficacy of incorporating the AHA Practice Standards and a review of studies highlighting their successful incorporation within patient care workflow. We conclude by outlining an "implementation blueprint" for health system professionals and administrators seeking to change their institution's culture of telemetry use. As the health care landscape continues to shift, enacting high-value initiatives that improve patient safety and efficiency of care will be critical.

Lung function trajectories and chronic obstructive pulmonary disease: current understanding and knowledge gaps.

PURPOSE OR REVIEW: Population-based studies have shown a significant heterogeneity in patients with chronic obstructive pulmonary disease (COPD), regarding both the attainment of maximal lung function and the subsequent decline over time. This review will highlight recent advances in the understanding of lung function trajectory in COPD, focusing on factors that influence peak adult lung function, markers of accelerated lung function decline and pharmacologic interventions in early phases of the disease. RECENT FINDINGS: Recent data have shown that individuals with lower lung function early in life will go on to develop lower forced expiratory volume in 1 s (FEV1) in adulthood. Smoking can amplify the effect of specific childhood exposures on maximal adult lung function. Clinical symptoms such as chronic mucous hypersecretion and the biomarker club cell secretory protein have been associated with lung function decline over time. New computed tomography imaging markers also show promise as a way to detect early small airway disease, but need to be examined more longitudinally. In addition to these advances, a slower decline in FEV1 has been demonstrated in two randomized clinical trials studying tiotropium and inhaled fluticasone. SUMMARY: A better understanding of lung function development and eventual decline in those at risk for progression to COPD will aide in a precision medicine approach, in which markers for those at risk of low maximal lung function and accelerated decline are identified. Targeted therapy can then be used early to modify disease activity and outcomes.

Bronchoscopic intubation is an effective airway strategy in critically ill patients.

PURPOSE: American Society of Anesthesiologists guidelines recommend the use of bronchoscopic intubation as a rescue technique in critically ill patients. We sought to assess the safety and efficacy of bronchoscopic intubation as an initial approach in critically ill patients. METHODS: We performed a retrospective cohort study of patients who underwent endotracheal intubation in the medical intensive care unit of a tertiary urban referral center over 1 academic year. The primary outcome was first-pass success rate. MEASUREMENTS AND MAIN RESULTS: We identified 219 patients who underwent either bronchoscopic (n=52) or laryngoscopic guided (n=167) intubation as the initial attempt. There was a higher first-pass success rate in the bronchoscopic intubation group than in the laryngoscopic group (96% vs 78%; P=.003). The bronchoscopic intubation group had a higher body mass index (28.4 vs 25.9; P=.027) and higher preintubation fraction of inspired oxygen requirement (0.73±0.27 vs 0.63±0.30; P=.044) than the laryngoscopic group. There were no cases of right mainstem intubation, esophageal intubation, or pneumothorax with bronchoscopic intubation. Rates of postintubation hypotension and hypoxemia were similar in both groups. The association with first-pass success remained with multivariate and propensity matched analysis. CONCLUSIONS: Bronchoscopic intubation as an initial strategy in critically ill patients is associated with a higher first-pass success rate than laryngoscopic intubation, and is not associated with an increase in complications.
