Inclusion criteria included age \u226565 years and new diagnosis of OSA. Exclusion criteria included evidence of prior OSA treatment during the 12 months prior to the index date, active cancer, or end-stage renal disease. OSA was defined using physician-assigned diagnostic codes. Common chronic conditions included chronic obstructive pulmonary disease, congestive heart failure, depression, hypertension, type 2 diabetes mellitus, obesity, and stroke. Based on Medicare policy, individuals were classified as adherers, nonadherers, or noninitiators. Risk adjustment was based on the Centers for Medicare and Medicaid Hierarchical Condition Categories approach developed by the Centers for Medicaid and Medicare Service specifically to estimate anticipated costs. To examine the impact of PAP adherence on costs, we employed a weighted DID regression framework to account for baseline variations in health status and other confounding factors.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Participants included 28\u2005220 Medicare beneficiaries with comorbid OSA. Of these, 45% were adherent to PAP, 10% were nonadherent, and 44% did not initiate PAP. Relative to noninitiators, beneficiaries who initiated PAP displayed $195 reduced per-member per-month costs over 24 months. This finding remained consistent across all seven medical and psychiatric subgroups, as well as among individuals with multimorbidity.<\/jats:p>\n               <\/jats:sec>\n
