Long-term trends in home respiratory medical equipment among U.S. Medicare patients.
The purpose of this study was to explore how respiratory durable medical equipment (DME) supply has changed since Medicare implemented the Competitive Bidding Program (CBP) in 2011and increased the scale of the program nationally in 2013 and 2016. The researchers analyzed all publicly available nationwide Medicare DME data from 2013 to 2019 and analyzed all respiratory DME included in the CBP (excluding accessories such as masks, tubing, and filters). The researchers found that the three highest-volume respiratory DME products were stationary oxygen concentrators, continuous positive airway pressure (CPAP) devices, and gaseous portable oxygen. Decreases in suppliers across all items and increases in claims per supplier for the majority of items suggest greater market concentration of respiratory DME suppliers for Medicare beneficiaries. Even as the Medicare population expanded by 2.6% between 2013 and 2019, the number of patients receiving home oxygen decreased, results that could represent reduced access to home oxygen DME. Finally, in contrast to declines in use for most home oxygen items, the percentage of Medicare beneficiaries using portable oxygen concentrators and CPAP devices increased significantly. The researchers conclude that this analysis addresses a critical knowledge gap and highlights the need for future work evaluating how policies such as the CBP affect respiratory DME access and outcomes.

CPAP adherence is associated with reduced inpatient utilization among older adult Medicare beneficiaries with pre-existing cardiovascular disease.
The purpose of this study was to examine the impact of adherence to continuous positive airway pressure (CPAP) therapy on health care utilization among a nationally representative and sample of older adults with multiple morbidities and pre-existing cardiovascular disease and subsequently diagnosed with obstructive sleep apnea in the United States. The investigators concluded that in this nationally representative sample of older Medicare beneficiaries with multiple morbidities and relative to low adherers, high adherers demonstrated reduced inpatient utilization.

The hospital readmissions reduction program and readmissions for chronic obstructive pulmonary disease, 2006-2015.
In October 2012, the initial phase of the Hospital Readmission Reduction Program imposed financial penalties on hospitals with higher-than-expected risk-adjusted 30-day readmission rates for Medicare beneficiaries with congestive heart failure, myocardial infarction, and pneumonia. In this study, the investigators hypothesized that these penalties may also be associated with decreased readmissions for chronic obstructive pulmonary disease (COPD) in the general population before COPD became a target condition (October 2014).

Impact of PAP therapy on hospitalization rates in Medicare beneficiaries with COPD and coexisting OSA.
This retrospective cohort study analyzed data from a national sample of fee-for-service Medicare beneficiaries with a diagnosis of chronic obstructive pulmonary disease (COPD) and coexisting obstructive sleep apnea (OSA) who had begun positive airway pressure (PAP) therapy in 2011. The effect of PAP therapy on emergency room visits and hospitalizations for all-cause and COPD-related conditions was also examined. PAP therapy was more beneficial for older adults, those with higher COPD complexity, and those with three or more comorbidities. PAP therapy in elderly patients with overlap syndrome is associated with a reduction in hospitalization for COPD-related conditions, but not for all-cause hospitalizations or ER visits.

Obstructive sleep apnea with chronic obstructive pulmonary disease among Medicare beneficiaries.
This research letter describes a claims-based study of Medicare beneficiaries conducted by the authors that examined the diagnosed prevalence and trend of overlap syndrome (the coexistence of chronic obstructive pulmonary disease [COPD] and obstructive sleep apnea [OSA] in a single individual). A total of 159,084 patients with COPD were included in the study; 11 percent had coexisting OSA. Data were gathered from multiple files: the Medicare Denominator File, the Medicare Provider Analysis and Review File, the Outpatient Standard Analytic File, the 100% Physician/Supplier Data File, and the Durable Medical Equipment File. Medicare enrollment files were used to gather information on patient characteristics and categorize subjects by age, sex, race, and socioeconomic status. The authors note that the prevalence of diagnosed overlap syndrome has increased fourfold during the 10-year study period.

Results of a Medicare bundled payments for care improvement initiative for chronic obstructive pulmonary disease readmissions.
This study evaluated whether a comprehensive chronic obstructive pulmonary disease (COPD) multidisciplinary intervention focusing on inpatient, transitional, and outpatient care as part of an institution's Bundled Payments for Care Improvement (BPCI) participation would reduce 30-day all-cause readmission rates for COPD exacerbations and reduce overall costs. It concluded that a Medicare BPCI intervention did not reduce 30-day all-cause readmission rates or overall costs after hospitalization for acute exacerbation of COPD.

Association of psychological disorders with 30-day readmission rates in patients with COPD.
Using a 5 percent sample of Medicare beneficiaries, the researchers examined the association of psychological disorders such as depression, anxiety, psychosis, alcohol abuse and drug abuse with early readmission for patients with COPD. They found that psychological disorders like depression, anxiety, psychosis, alcohol abuse and drug abuse are independently associated with higher all-cause 30-day readmission rates for Medicare beneficiaries with COPD.

Understanding why patients with COPD get readmitted: a large national study to delineate the Medicare population for the readmissions penalty expansion.
The Hospital Readmissions Reduction Program (HRRP) penalizes hospitals for 30-day readmissions and was extended to COPD in October 2014. The authors investigated readmission risk factors and reasons for readmission in order to guide hospitals in initiating programs to reduce COPD readmissions. They found that patients discharged home without home care were more likely to be readmitted for COPD than patients discharged to post-acute care, and those readmitted were more likely to be dually enrolled in Medicare and Medicaid, have a longer median length of stay, and have more comorbidities. They concluded that the addition of COPD to the readmissions penalty may further worsen the disproportionately high penalties seen in safety net hospitals.

Oxygen therapy use in older adults with chronic obstructive pulmonary disease.
The researchers examined national trends and factors associated with the use of oxygen therapy and sustained oxygen therapy in older adults with COPD between 2001 and 2010. They found an increase in oxygen therapy use but a decrease in sustained oxygen therapy in fee-for-service Medicare beneficiaries with COPD from 2001 to 2010.
