RESUMO
Rationale: Respiratory conditions account for a large proportion of health care spending in the United States. A full characterization of spending across multiple conditions and over time has not been performed. Objectives: To estimate health care spending in the United States for 11 respiratory conditions from 1996 to 2016, providing detailed trends and an evaluation of factors associated with spending growth. Methods: We extracted data from the Institute of Health Metrics and Evaluation's Disease Expenditure Project Database, producing annual estimates in spending for 38 age and sex groups, 7 types of care, and 3 payer types. We performed a decomposition analysis to estimate the change in spending associated with changes in each of five factors (population growth, population aging, disease prevalence, service usage, and service price and intensity). Measurements and Main Results: Total spending across all respiratory conditions in 2016 was $170.8 billion (95% confidence interval [CI], $164.2-179.2 billion), increasing by $71.7 billion (95% CI, $63.2-80.8 billion) from 1996. The respiratory conditions with the highest spending in 2016 were asthma and chronic obstructive pulmonary disease, contributing $35.5 billion (95% CI, $32.4-38.2 billion) and $34.3 billion (95% CI, $31.5-37.3 billion), respectively. Increasing service price and intensity were associated with 81.4% (95% CI, 70.3-93.0%) growth from 1996 to 2016. Conclusions: U.S. spending on respiratory conditions is high, particularly for chronic conditions like asthma and chronic obstructive pulmonary disease. Our findings suggest that service price and intensity, particularly for pharmaceuticals, should be a key focus of attention for policymakers seeking to reduce health care spending growth.

PURPOSE: In-person visits with a trained therapist have been standard care for patients initiating continuous positive airway pressure (CPAP). These visits provide an opportunity for hands-on training and an in-person assessment of mask fit. However, to improve access, many health systems are shifting to remote CPAP initiation with equipment mailed to patients. While there are potential benefits of a mailed approach, relative patient outcomes are unclear. Specifically, many have concerns that a lack of in-person training may contribute to reduced CPAP adherence. To inform this knowledge gap, we aimed to compare treatment usage after in-person or mailed CPAP initiation. METHODS: Our medical center shifted from in-person to mailed CPAP dispensation in March 2020 during the COVID-19 pandemic. We assembled a cohort of patients with newly diagnosed obstructive sleep apnea (OSA) who initiated CPAP in the months before (n = 433) and after (n = 186) this shift. We compared 90-day adherence between groups. RESULTS: Mean nightly PAP usage was modest in both groups (in-person 145.2, mailed 140.6 min/night). We did not detect between-group differences in either unadjusted or adjusted analyses (adjusted difference - 0.2 min/night, 95% - 27.0 to + 26.5). CONCLUSIONS: Mail-based systems of CPAP initiation may be able to improve access without reducing CPAP usage. Future work should consider the impact of mailed CPAP on patient-reported outcomes and the impact of different remote setup strategies.

BACKGROUND: Implementation of effective smoking cessation interventions in lung cancer screening has been identified as a high-priority research gap, but knowledge of current practices to guide process improvement is limited due to the slow uptake of screening and dearth of data to assess cessation-related practices and outcomes under real-world conditions. OBJECTIVE: To evaluate cessation treatment receipt and 1-year post-screening cessation outcomes within the largest integrated healthcare system in the USA-the Veterans Health Administration (VHA). Design Observational study using administrative data from electronic medical records (EMR). Patients Currently smoking Veterans who received a first lung cancer screening test using low-dose CT (LDCT) between January 2014 and June 2018. Main Outcomes Tobacco treatment received within the window of 30 days before and 30 days after LDCT; 1-year quit rates based on EMR Smoking Health Factors data 6-18 months after LDCT. Key Results Of the 47,609 current smokers screened (95.3% male), 8702 (18.3%) received pharmacotherapy and/or behavioral treatment for smoking cessation; 531 (1.1%) received both. Of those receiving pharmacotherapy, only one in four received one of the most effective medications: varenicline (12.1%) or combination nicotine replacement therapy (14.3%). Overall, 5400 Veterans quit smoking-a rate of 11.3% (missing=smoking) or 13.5% (complete case analysis). Treatment receipt and cessation were associated with numerous sociodemographic, clinical, and screening-related factors. CONCLUSIONS: One-year quit rates for Veterans receiving lung cancer screening in VHA are similar to those reported in LDCT clinical trials and cohort studies (i.e., 10-17%). Only 1% of Veterans received the recommended combination of pharmacotherapy and counseling, and the most effective pharmacotherapies were not the most commonly received ones. The value of screening within VHA could be improved by addressing these treatment gaps, as well as the observed disparities in treatment receipt or cessation by race, rurality, and psychiatric conditions.

BACKGROUND: Inhaled corticosteroid (ICS) use among patients with COPD increases the risk of pneumonia and other complications. Current recommendations limit ICS use to patients with frequent or severe COPD exacerbations. However, use of ICS among patients with COPD is common and may be occurring both among those with mild disease (overuse) and those misdiagnosed with COPD (misuse). OBJECTIVE: To identify patients without identifiable indication for ICS and assess patient and provider characteristics associated with potentially inappropriate to targeted in de-implementation efforts DESIGN: We performed a cross-sectional study of patients with COPD in the Veterans Affairs (VA) system with recent spirometry. PARTICIPANTS: After setting an index date, we identified individuals with a clinical diagnosis of COPD who had spirometry completed in the prior 5 years. We excluded individuals with an appropriate indication for ICS based on the 2017 GOLD statement, including asthma and a recent history of frequent or severe exacerbations. MAIN MEASURES: ICS use without identifiable indication KEY RESULTS: We identified 26,536 patients with COPD without an identifiable indication for ICS. Nearly » of patients (n = 6330) filled ≥2 prescriptions for ICS in the year prior to the index date. We found that older age (adjusted prevalence ratio [APR] 1.06 per decade, 95% confidence interval [CI] 1.04-1.08), white race (APR 1.11, 95% CI 1.05-1.19), and more primary care visits (APR 1.05 per visit, 95% CI 1.03-1.07) were associated with increased likelihood of potentially inappropriate use. Primary care clinic complexity and provider training were not associated with ICS use. Among patients misdiagnosed with COPD, we found that 14% used ICS. CONCLUSIONS: Potentially inappropriate ICS use is common among patients with and without airflow obstruction who are diagnosed with COPD. We identified patient comorbidities and patterns of healthcare utilization that increase the likelihood of ICS use that could be targeted for system-level de-implementation interventions.

Quality of chronic obstructive pulmonary disease (COPD) care is thought to be an important intermediate process to improve the well-being of patients admitted to hospital for exacerbation. We sought to examine the quality of inpatient COPD care and the associations with readmission and mortality. We performed a cohort study of 2,364 veterans aged over 40 and hospitalized for COPD between 2005 and 2011 at five Department of Veterans Affairs hospitals. We examined whether patients received six guideline recommended care items including short-acting bronchodilators, corticosteroids, antibiotics, positive-pressure ventilation (in cases of acute hypercarbic respiratory failure), chest imaging, and arterial blood gas measurement. Our primary outcome was all-cause hospital readmission or death within 30 days. Overall quality of care was not significantly associated with readmission or death (acute care aOR 0.98; 95% CI 0.87-1.11; ICU aOR 0.89; 95% CI 0.71-1.13). Delivery of corticosteroids and antibiotics was associated with reduced odds of readmission and death (aOR 0.77; 95% CI 0.61-0.92). Few patients received all of the recommended care items (18% of acute care, 38% of ICU patients). Quality of care did not vary by race or sex but did vary significantly across sites and did not improve over time. Our composite measure of COPD care quality was not associated with readmission or death. Further efforts are needed to improve care delivery to patients hospitalized with COPD.

BACKGROUND: Many smokers admitted for chronic obstructive pulmonary disease (COPD) are not given smoking cessation medications at discharge. The reasons behind this are unclear, and may reflect an interplay of patient characteristics, health disparities, and the receipt of inpatient tobacco control processes. OBJECTIVES: We aimed to assess potential disparities in treatment for tobacco use following discharge for COPD, examined in the context of inpatient tobacco control processes. PARTICIPANTS: Smokers aged ≥ 40 years, admitted for treatment of a COPD exacerbation within the VA Veterans Integrated Service Network 20, identified using ICD-9 discharge codes and admission diagnoses from 2005-2012. MAIN MEASURES: The outcome was any tobacco cessation medication dispensed within 48 hours of discharge. We assessed potential predictors administratively up to 1 year prior to admission. We created the final logistic regression model using manual model building, clustered by site. Variables with p < 0.2 in biviariate models were considered for inclusion in the final model. RESULTS: We identified 1511 subjects. 16.9 % were dispensed a medication at discharge. In the adjusted model, several predictors were associated with decreased odds of receiving medications: older age (OR per year older 0.96, 95 % CI 0.95-0.98), black race (OR 0.34, 95 % CI 0.12-0.97), higher comorbidity score (OR 0.89, 95 % CI 0.82-0.96), history of psychosis (OR 0.40, 95 % CI 0.31-0.52), hypertension (OR 0.75, 95 % CI 0.62-0.90), and treatment with steroids in the past year (OR 0.80, 95 % CI 0.70-0.90). Inpatient tobacco control processes were associated with increased odds of receiving medications: documented brief counseling at discharge (OR 3.08, 95 % CI 2.02-4.68) and receipt of smoking cessation medications while inpatient (OR 5.95, 95 % CI 3.19-11.10). CONCLUSIONS: Few patients were treated with tobacco cessation medications at discharge. We found evidence for disparities in treatment, but also potentially beneficial effects of inpatient tobacco control measures. Further focus should be on using novel processes of care to improve provision of medications and decrease the observed disparities.

In October 2014, the U.S. Centers for Medicare and Medicaid Services (CMS) will expand its Hospital Readmission Reduction Program (HRRP) to include chronic obstructive pulmonary disease (COPD). Under the new policy, hospitals with high risk-adjusted, 30-day all-cause unplanned readmission rates after an index hospitalization for a COPD exacerbation will be penalized with reduced reimbursement for the treatment of Medicare beneficiaries. In this perspective, we review the history of the HRRP, including the recent addition of COPD to the policy. We critically assess the use of 30-day all-cause COPD readmissions as an accountability measure, discussing potential benefits and then highlighting the substantial drawbacks and potential unintended consequences of the measure that could adversely affect providers, hospitals, and patients with COPD. We conclude by emphasizing the need to place the 30-day COPD readmission measure in the context of a reconceived model for postdischarge quality and review several frameworks that could help guide this process.

Rationale: Prescription formularies specify which medications are available to patients. Formularies change frequently, potentially forcing patients to switch medications for nonclinical indications (nonmedical switching). Nonmedical switching is known to impact disease control and adherence. The consequences of nonmedical switching have not been rigorously studied in COPD. Methods: We conducted a cohort study of Veterans with COPD on inhaler therapy in January 2016 when formoterol was removed from the Department of Veterans Affairs (VA) national formulary. A 2-point difference-in-differences analysis using multivariable negative binomial and generalized linear models was performed to estimate the association of the formulary change with patient outcomes in the 6 months before and after the change. Our primary outcome was the number of COPD exacerbations in 6 months, with secondary outcomes of total health care encounters and encounter-related costs in 6 months. Results: We identified 10,606 Veterans who met our inclusion criteria, of which 409 (3.9%) experienced nonmedical switching off formoterol. We did not identify a change in COPD exacerbations (-0.04 exacerbations; 95% confidence interval [CI] -0.12, 0.03) associated with the formulary change. In secondary outcome analysis, we did not observe a change in the number of health care encounters (-0.12 visits; 95% CI -1.00, 0.77) or encounter-related costs ($369; 95% CI -$1141, $1878). Conclusions: Among COPD patients on single inhaler therapy, nonmedical inhaler switches due to formulary discontinuation of formoterol were not associated with changes in COPD exacerbations, encounters, or encounter-related costs. Additional research is needed to confirm our findings in more severe disease and other settings.
RESUMO
Rationale: Nonbenzodiazepine benzodiazepine receptor agonists (NBZRA, e.g., zolpidem) are frequently used to treat insomnia among patients with chronic obstructive pulmonary disease (COPD). However, multiple observational studies find that patients with COPD who are prescribed NBZRAs have greater risks for mortality and respiratory complications than patients without such prescriptions. Without an active comparator, these studies are susceptible to confounding by indication. Objectives: Compare the risk of death or inpatient COPD exacerbation among patients receiving zolpidem relative to patients receiving other hypnotics. Methods: Using nationwide Veterans Health Administration (VA) data, we identified patients with clinically diagnosed COPD and new receipt of zolpidem or another hypnotic available on VA formulary without prior authorization (melatonin, trazodone, doxepin). We excluded those receiving traditional benzodiazepines or multiple concurrent hypnotics. We propensity-matched patients receiving zolpidem to other hypnotics on 32 variables, including demographics, comorbidities, and markers of COPD severity. We compared risk of the primary composite outcome of death or inpatient COPD exacerbation over 1 year. In secondary analyses, we propensity-matched patients receiving zolpidem to those without hypnotic receipt. Results: Among 283,740 patients meeting inclusion criteria, 1,126 (0.4%) received zolpidem and 3,057 (1.1%) received other hypnotics. We propensity-matched patients receiving zolpidem 1:1 to peers receiving other hypnotics. We did not find a difference in the primary composite outcome of death or inpatient exacerbation (hazard ratio, 0.97; 95% confidence interval [CI], 0.77-1.23). In secondary analyses comparing patients receiving zolpidem to matched peers without hypnotic receipt, we observed greater risk of death or inpatient exacerbation with zolpidem (hazard ratio, 1.40; 95% CI, 1.09-1.81). Conclusions: Among patients with COPD, we did not observe greater risks after new receipt of zolpidem relative to other hypnotics. However, we did observe greater risks relative to those without hypnotic receipt. This latter finding may reflect: 1) residual, unmeasured confounding related to insomnia; or 2) true adverse effects of hypnotics across classes. Future work is needed to better understand the risks of hypnotics in COPD.

Study Objectives: Observational studies link untreated obstructive sleep apnea (OSA) with adverse outcomes in chronic obstructive pulmonary disease (COPD). The first step in addressing OSA is a clinical assessment. However, given competing demands and a lack of high-quality evidence, it is unclear how often such assessments occur. We explored the documentation of OSA assessment among patients with COPD in primary care, and the patient and provider characteristics associated with these assessments. Methods: We conducted a cross-sectional study of patients with clinically diagnosed COPD at 2 primary care practices. We abstracted charts to determine whether providers assessed OSA, defined as documentation of symptoms, treatment, or a referral to sleep medicine. We performed multivariable mixed-effects logistic regression to assess the associations of patient and provider characteristics with OSA assessment. Results: Among 641 patients with clinically diagnosed COPD, 146 (23%) had OSA assessed over a 1-year period. Positive associations with OSA assessment included body mass index ≥ 30 (odds ratio [OR] 3.5, 95% confidence interval [CI] 1.8-7.0), pulmonary subspecialist visits (OR 3.9, 95%CI 2.4-6.3), and a prior sleep study demonstrating OSA documented within the electronic medical record (OR 18.0, 95%CI 9.0-35.8). Notably, patients identifying as Black were less likely to have OSA assessed than those identifying as White (OR 0.5, 95%CI 0.2-0.9). Conclusions: Providers document an assessment of OSA among a quarter of patients with COPD. Our findings highlight the importance of future work to rigorously test the impact of assessment on important health outcomes. Our findings also reinforce that additional strategies are needed to improve the equitable delivery of care.
RESUMO
RATIONALE: The American Thoracic Society recommended a single reference equation for spirometry but the impact to patients is not known. OBJECTIVE: To estimate the effect of changing to a single reference equation among Veterans with chronic obstructive pulmonary disease (COPD). METHODS: Cross-sectional study including Veterans aged ≥40 to ≤89 years with COPD and spirometry results from 21 facilities between 2010 - 2019. We collected race/ethnicity data from the electronic health record. We estimated the percentage change in the number of Veterans with lung function meeting clinical thresholds used to determine eligibility for lung resection for cancer, lung volume reduction surgery (LVRS), and lung transplant referral. We estimated the change for each level of VA service connection and financial impact. RESULTS: We identified 44,892 Veterans; Asian (0.5%), Black (11.8%), White (80.8%), and Hispanic (1.8%). When changing to a single reference equation, Asian and Black Veterans had reduced predicted lung function that could result in less surgical lung resection (4.4% and 11.1% respectively), while increasing LVRS (1.7% and 3.8%), and lung transplant evaluation for Black Veterans (1.2%). White Veterans had increased predicted lung function and could experience increased lung resection (8.1%), with less LVRS (3.3%), and lung transplant evaluation (0.9%). Some Asian and Black Veterans could experience an increase in monthly disability payments (+$540.38 and $398.38), while Hispanic White and White Veterans could see a decrease (-$588.79). When aggregated, Hispanic Veterans experienced changes attributable to their racial identity, and because this sample was predominantly Hispanic White, had similar results to White Veterans. CONCLUSIONS: Changing the reference equation could affect access to treatment and disability benefits, depending on race. If adopted, the use of discrete clinical thresholds needs to be reassessed, considering patient-centered outcomes.
RESUMO
IMPORTANCE: Communication about end-of-life care is a core clinical skill. Simulation-based training improves skill acquisition, but effects on patient-reported outcomes are unknown. OBJECTIVE: To assess the effects of a communication skills intervention for internal medicine and nurse practitioner trainees on patient- and family-reported outcomes. DESIGN, SETTING, AND PARTICIPANTS: Randomized trial conducted with 391 internal medicine and 81 nurse practitioner trainees between 2007 and 2013 at the University of Washington and Medical University of South Carolina. INTERVENTION: Participants were randomized to an 8-session, simulation-based, communication skills intervention (N = 232) or usual education (N = 240). MAIN OUTCOMES AND MEASURES: Primary outcome was patient-reported quality of communication (QOC; mean rating of 17 items rated from 0-10, with 0 = poor and 10 = perfect). Secondary outcomes were patient-reported quality of end-of-life care (QEOLC; mean rating of 26 items rated from 0-10) and depressive symptoms (assessed using the 8-item Personal Health Questionnaire [PHQ-8]; range, 0-24, higher scores worse) and family-reported QOC and QEOLC. Analyses were clustered by trainee. RESULTS: There were 1866 patient ratings (44% response) and 936 family ratings (68% response). The intervention was not associated with significant changes in QOC or QEOLC. Mean values for postintervention patient QOC and QEOLC were 6.5 (95% CI, 6.2 to 6.8) and 8.3 (95% CI, 8.1 to 8.5) respectively, compared with 6.3 (95% CI, 6.2 to 6.5) and 8.3 (95% CI, 8.1 to 8.4) for control conditions. After adjustment, comparing intervention with control, there was no significant difference in the QOC score for patients (difference, 0.4 points [95% CI, -0.1 to 0.9]; P = .15) or families (difference, 0.1 [95% CI, -0.8 to 1.0]; P = .81). There was no significant difference in QEOLC score for patients (difference, 0.3 points [95% CI, -0.3 to 0.8]; P = .34) or families (difference, 0.1 [95% CI, -0.7 to 0.8]; P = .88). The intervention was associated with significantly increased depression scores among patients of postintervention trainees (mean score, 10.0 [95% CI, 9.1 to 10.8], compared with 8.8 [95% CI, 8.4 to 9.2]) for control conditions; adjusted model showed an intervention effect of 2.2 (95% CI, 0.6 to 3.8; P = .006). CONCLUSIONS AND RELEVANCE: Among internal medicine and nurse practitioner trainees, simulation-based communication training compared with usual education did not improve quality of communication about end-of-life care or quality of end-of-life care but was associated with a small increase in patients' depressive symptoms. These findings raise questions about skills transfer from simulation training to actual patient care and the adequacy of communication skills assessment.

Rationale: Guidelines recommend inhaled corticosteroids (ICS) for patients with chronic obstructive pulmonary disease (COPD) and select indications, including asthma history, high exacerbation risk, or high serum eosinophils. ICS are commonly prescribed outside of these indications, despite evidence of harm. We defined a "low-value" ICS prescription as the receipt of an ICS without evidence of a guideline-recommended indication. ICS prescription patterns are not well characterized and could inform health system interventions to reduce low-value practices. Objectives: To evaluate the national trends in initial low-value ICS prescriptions in the U.S. Department of Veterans Affairs and to determine whether rural-urban differences in low-value ICS prescribing exist. Methods: We performed a cross-sectional study between January 4, 2010, and December 31, 2018, identifying veterans with COPD who were new users of inhaler therapy. We defined low-value ICS as prescriptions in patients with 1) no asthma, 2) low risk of future exacerbation (Global Initiative for Chronic Obstructive Lung Disease group A or B), and 3) serum eosinophils <300 cells/µl. We performed multivariable logistic regression to evaluate trends in low-value ICS prescription over time, adjusting for potential confounders. We performed fixed effects logistic regression to assess rural-urban prescribing patterns. Results: We identified a total of 131,009 veterans with COPD starting inhaler therapy, 57,472 (44%) of whom were prescribed low-value ICS as initial therapy. From 2010 to 2018, the probability of receiving low-value ICS as initial therapy increased by 0.42 percentage points per year (95% confidence interval, 0.31-0.53). Compared with urban residence, rural residence was associated with a 2.5-percentage-point (95% confidence interval, 1.9-3.1) higher probability of receiving low-value ICS as initial therapy. Conclusions: The prescription of low-value ICS as initial therapy is common and increasing slightly over time for both rural and urban veterans. Given the widespread and persistent nature of low-value ICS prescribing, health system leaders should consider system-wide approaches to address this low-value prescribing practice.

Purpose: While home oxygen therapy increases survival in patients with chronic obstructive pulmonary disease (COPD) who have severe resting hypoxemia, recent evidence suggests that there is no survival benefit of home oxygen for patients with COPD who have isolated exertional desaturation. We aimed to understand clinician practice patterns surrounding the prescription of home oxygen for patients with COPD. Methods: We conducted semi-structured qualitative interviews via videoconference with 15 physicians and 3 nurse practitioners who provide care for patients with COPD. Clinicians were recruited through the American Lung Association Airways Clinical Research Centers. Interview guides were created with the assistance of patient investigators and included questions regarding clinician practices surrounding the prescription of oxygen for patients with COPD and the use of clinical guidelines. Interviews were recorded, transcribed, and coded for themes. Results: Of the 18 clinician interviewees, one-third were women, with most participants (n=11) being < 50 years old. Results of the semi-structured interviews suggested research evidence, clinical experience, and patient preferences contributed to clinician decision-making. Most clinicians described a shared decision-making process for prescribing home oxygen for patients, including discussion of risks and benefits, and developing an understanding of patient values and preferences. Clinicians did not use a structured tool to conduct these conversations. Conclusions: Clinicians consider a number of patient and clinical factors when prescribing home oxygen therapy, often using a shared decision-making process. Tools to support shared decision-making about the use of home oxygen are needed.
RESUMO
Rationale: Many advocate the application of propensity-matching methods to real-world data to answer key questions around obstructive sleep apnea (OSA) management. One such question is whether identifying undiagnosed OSA impacts mortality in high-risk populations, such as those with chronic obstructive pulmonary disease (COPD). Objectives: Assess the association of sleep testing with mortality among patients with COPD and a high likelihood of undiagnosed OSA. Methods: We identified patients with COPD and a high likelihood of undiagnosed OSA. We then distinguished those receiving sleep testing within 90 days of index COPD encounters. We calculated propensity scores for testing based on 37 variables and compared long-term mortality in matched groups. In sensitivity analyses, we compared mortality using inverse propensity weighting and instrumental variable methods. We also compared the incidence of nonfatal events including adverse outcomes (hospitalizations and COPD exacerbations) and routine services that are regularly indicated in COPD (influenza vaccination and pulmonary function testing). We compared the incidence of each nonfatal event as a composite outcome with death and separately compared the marginal probability of each nonfatal event independently, with death as a competing risk. Results: Among 135,958 patients, 1,957 (1.4%) received sleep testing. We propensity matched all patients with sleep testing to an equal number without testing, achieving excellent balance on observed confounders, with standardized differences < 0.10. We observed lower mortality risk among patients with sleep testing (incidence rate ratio, 0.88; 95% confidence interval [CI], 0.79-0.99) and similar results using inverse propensity weighting and instrumental variable methods. Contrary to mortality, we found that sleep testing was associated with a similar or greater risk for nonfatal adverse events, including inpatient COPD exacerbations (subhazard ratio, 1.29; 95% CI, 1.02-1.62) and routine services like influenza vaccination (subhazard ratio, 1.26; 95% CI, 1.17-1.36). Conclusions: Our disparate findings can be interpreted in multiple ways. Sleep testing may indeed cause both reduced mortality and greater incidence of nonfatal adverse outcomes and routine services.
