Health and Economic Impact of Different Long-Term Oxygen Therapeutic Strategies in Patients with Chronic Respiratory Failure: A French Nationwide Health Claims Database (SNDS) Study

INTRODUCTION

Long-term oxygen therapy (LTOT) is reported to improve survival in patients with chronic respiratory failure. We aimed to describe effectiveness, burden, and cost of illness of patients treated with portable oxygen concentrators (POC) compared to other LTOT options.

METHODS

This retrospective comparative analysis included adult patients with chronic respiratory insufficiency and failure (CRF) upon a first delivery of LTOT between 2014 and 2019 and followed until December 2020, based on the French national healthcare database SNDS. Patients using POC, alone or in combination, were compared with patients using stationary concentrators alone (aSC), or compressed tanks (CTC) or liquid oxygen (LO2), matched on the basis of age, gender, comorbidities, and stationary concentrator use.

RESULTS

Among 244,719 LTOT patients (mean age 75 ± 12, 48% women) included, 38% used aSC, 46% mobile oxygen in the form of LO2 (38%) and POC (18%), whereas 9% used CTC. The risk of death over the 72-month follow-up was estimated to be 13%, 15%, and 12% lower for patients in the POC group compared to aSC, CTC, and LO2, respectively. In the POC group yearly mean total costs per patient were 5% higher and 4% lower compared to aSC and CTC groups, respectively, and comparable in the LO2 group. The incremental cost-effectiveness ratio (ICER) of POC was €8895, €6288, and €13,152 per year of life gained compared to aSC, CTC, and LO2, respectively.

CONCLUSION

Within the POC group, we detected an association between higher mobility (POCs autonomy higher than 5 h), improved survival, lower costs, and ICER - €6 238, compared to lower mobility POCs users.

Health and Demographic Factors for Chronic Obstructive Pulmonary Disease Among Hispanic Adults in the United States: Analysis of Behavioral Risk Factor Surveillance System Survey Data

Introduction: Appropriate diagnosis and regular primary care appointments are markers of quality chronic obstructive pulmonary disease (COPD) care. Underdiagnosis of COPD has been associated with an absence of health insurance, lower socioeconomic status, and race and ethnicity. Methods: This study examined predictors of COPD using data from the Behavioral Risk Factor Surveillance System (BRFSS, 2021) to provide information for prevention messaging and interventions. Participants included Hispanic adults (n = 17,782) aged 45 years and older. Chi-square tests and a multinomial logistic regression analysis (adjusted with the BRFSS weighting variable) were used to understand how sex, income, health status, smoking behaviors, asthma morbidity, and health insurance coverage were related to having COPD. Results: Patients with poor health, lower income level, current smokers, former smokers, or asthma were more likely to report COPD. Females were more likely to report COPD than males. Patients with COPD were more likely to be without health insurance when compared to those who did not have COPD, indicating unmet medical needs. Conclusion: Studies such as this one, aiming to evaluate the relationship between COPD prevalence and predictors of health and outcomes among Hispanic patients in the United States will remain important for developing health messaging to attenuate disease progression.

Smoke-Free Policies and 30-Day Mortality Rates for Chronic Obstructive Pulmonary Disease

BACKGROUND

Smoke-free policies have been shown to impact 30-day readmission rates due to chronic obstructive pulmonary disease (COPD) among adults aged ≥65 years. However, little is known about the association between smokefree policies and 30-day mortality rates for COPD. Therefore, we investigated the association between comprehensive smoke-free policies and 30-day mortality rates for COPD.

METHODS

We used a cross-sectional study design and retrospectively examined risk-adjusted 30-day mortality rates for COPD across US hospitals in 1171 counties. Data were sourced from Centers for Medicare and Medicaid Services (CMS) Hospital Value-Based Purchasing (HVBP) Program, American Hospital Association (AHA) Annual Surveys, US Census Bureau Current Population Survey, and US Tobacco Control Laws Database from the American Nonsmokers' Rights Foundation (ANRF). Data were averaged at the county level for years 2015-2018. Hierarchical Poisson models adjusted for differences in hospital characteristics and accounted for the clustering of hospitals within a county were used.

RESULTS

Our findings show a consistent association between stronger smoke-free policies and a reduction in COPD mortality. When evaluating smoke-free policy, county characteristics, and hospital characteristics individually, we found that counties with full coverage or partial coverage had a reduced incidence rate of COPD mortality compared to no coverage counties. After adjusting for the county and hospital characteristics, counties with full coverage of smoke-free policies had a reduced rate of 30-day COPD mortality (adjusted incidence rate ratio [IRR]: 0.87, 95% CI: 0.79, 0.96) compared to counties with no policy coverage.

CONCLUSION

Comprehensive smoke-free policies are associated with a reduction in 30-day mortality following hospital admission for COPD. Partial smoke-free legislation is an insufficient preventative measure. These findings have strong implications for hospital policy-makers, suggesting that policy interventions to reduce COPD-related 30-day mortality should include implementing smoke-free policies and public health policy-makers to incentivize comprehensive smokefree policies.

Quality Standard Position Statements for Health System Policy Changes in Diagnosis and Management of COPD: A Global Perspective

Introduction

Despite being a leading cause of death worldwide, chronic obstructive pulmonary disease (COPD) is underdiagnosed and underprioritized within healthcare systems. Existing healthcare policies should be revisited to include COPD prevention and management as a global priority. Here, we propose and describe health system quality standard position statements that should be implemented as a consistent standard of care for patients with COPD.

Methods

A multidisciplinary group of clinicians with expertise in COPD management together with patient advocates from eight countries participated in a quality standards review meeting convened in April 2021. The principal objective was to achieve consensus on global health system priorities to ensure consistent standards of care for COPD. These quality standard position statements were either evidence-based or reflected the combined views of the panel.

Results

On the basis of discussions, the experts adopted five quality standard position statements, including the rationale for their inclusion, supporting clinical evidence, and essential criteria for quality metrics. These quality standard position statements emphasize the core elements of COPD care, including (1) diagnosis, (2) adequate patient and caregiver education, (3) access to medical and nonmedical treatments aligned with the latest evidence-based recommendations and appropriate management by a respiratory specialist when required, (4) appropriate management of acute COPD exacerbations, and (5) regular patient and caregiver follow-up for care plan reviews.

Conclusions

These practical quality standards may be applicable to and implemented at both local and national levels. While universally applicable to the core elements of appropriate COPD care, they can be adapted to consider differences in healthcare resources and priorities, organizational structure, and care delivery capabilities of individual healthcare systems. We encourage the adoption of these global quality standards by policymakers and healthcare practitioners alike to inform national and regional health system policy revisions to improve the quality and consistency of COPD care worldwide.

Frailty Among Older Individuals with and without COPD: A Cohort Study of Prevalence and Association with Adverse Outcomes

Rationale

Frailty prevalence estimates among individuals with COPD have varied widely, and few studies have investigated relationships between frailty and adverse outcomes in a COPD population.

Objective(s)

Describe frailty prevalence among individuals with and without COPD and examine associations between frailty and mortality and other adverse outcomes in the next two years.

Methods

This was an observational cohort study using Health and Retirement Study data (2006–2018) of community living individuals ages 50–64 and ≥65 with and without COPD (non-COPD). Frailty (Fried phenotype [5 items], and a modified Frailty Index-Comprehensive Geriatric Assessment [Enhanced FI-CGA] [37 items], and debility (modified BODE Index [4 items]) were assessed. Two-year post-assessment outcomes (mortality, ≥1 inpatient stay, home health and skilled nursing facility (SNF) use) were reviewed in a population matched 3:1 (non-COPD: COPD) on age, sex, race, and year using univariate and multivariate logistic regression (adjusted for morbidities). Area-under-the-curve (AUC) was used to evaluate regressions.

Results

The study included 18,979 survey observations for age 50–64, and 24,162 age ≥65; 7.8% and 12.0% respectively reporting a diagnosis of COPD. Fried phenotype frailty prevalence for age ≥65 was 23.1% (COPD) and 9.4% (non-COPD), and for the Enhanced FI-CGA, 45.9% (COPD) and 22.4% (non-COPD). Two-year mortality for COPD was more than double non-COPD for age 50–64 (95% CI: 3.8–5.9% vs 0.7–1.3%) and age ≥65 (95% CI: 11.9–14.3% vs 5.6–6.6%). Inpatient utilization, home health care use, or at least temporary SNF placement were also more frequent for COPD. Measures were predictive of adverse outcomes. In adjusted models, the Fried phenotype and modified BODE score performed similarly, and both performed better than the Enhanced FI-CGA index. AUC values were higher for morality regressions.

Conclusion

Frailty prevalence among individuals with COPD in this national survey is substantially greater than without COPD, even at pre-retirement (50–64 years). These measures identify patients with increased risk of poor outcomes.

Common Mental Disorders, Functional Limitation and Diet Quality Trends and Related Factors among COPD Patients in Spain, 2006-2017: Evidence from Spanish National Health Surveys

Certain conditions such as common mental disorders (CMDs), functional limitation (FL) and poor diet quality may affect the lives of individuals who suffer from chronic obstructive pulmonary disease (COPD). This study sought to examine time trends in the prevalence of CMDs, FL and diet quality among male and female COPD patients living in Spain from 2006 to 2017 and to identify which factors were related to CMDs, FL and a poor/improvable diet quality in these patients. We performed a cross-sectional study among COPD patients aged ≥ 40 years old using data from the Spanish National Health Surveys conducted in 2006, 2011 and 2017, identifying a total of 2572 COPD patients. Binary logistic regressions were performed to determine the characteristics related to CMDs, FL and poor/improvable diet quality. Over the years of the study, the prevalence of FL among female COPD patients increased (p for trend <0.001). In addition, CMDs were associated to body mass index (BMI), educational level, physical activity, smoking status, occupation, chronic conditions and alcohol consumption; FL was related to age, living with a partner, educational level, physical activity and chronic conditions; and poor/improvable diet quality was associated to age, smoking status, BMI and physical activity.

Frailty in Korean patients with chronic obstructive pulmonary disease, using data from the Korea National Health and Nutrition Examination Survey, 2015 and 2016

AIM

To describe frailty, to identify its determinants, and to examine how it affected functioning in Korean patients with chronic obstructive pulmonary disease (COPD). This analysis was based on datasets from the Korea National Health and Nutrition Examination Survey (KNHANES).

BACKGROUND

Most of what is known about the prevalence and determinants of frailty in patients with COPD has come from countries other than Korea. Examining this issue with a representative sample of COPD patients in Korea will shed light on frailty in this population.

METHODS

This cross-sectional study, a secondary data analysis, used datasets from the KNHANES VI (2015) and VII (2016) to understand frailty in 417 patients with COPD (mean age = 65.36; FEV1%predicted value = 78.91). Demographic and clinical data, symptoms, self-rated health, frailty, and functioning were collected in health interviews and health examinations. Descriptive and inferential statistics were used to analyze the data.

RESULTS

One hundred forty-eight participants (35.5%) were frail, 156 (37.4%) were pre-frail, and 113 (27.1%) exhibited no frailty. Multivariate logistic regression showed that self-rated health, stage of COPD based on the Global Initiative for Chronic Obstructive Lung Disease, pain/discomfort, and arthritis were significant predictors of frailty. Multivariate logistic regression also showed that frail participants were more likely to experience limitations in usual activities, after controlling for other covariates.

CONCLUSION

Health care providers who know the determinants of frailty and its relationship with poor functioning will be better prepared to identify at-risk patients with COPD who might benefit from pulmonary rehabilitation.
