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.

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.
