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.

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.
