The difference in MS between ACO participants and nonparticipants was larger in more concentrated markets relative to less concentrated markets. ACO participation was associated with increases in mean MS of 1.7 percentage points (PP) for net patient revenue, 2.0 PP for discharges, and 1.6 PP for beds.

Our finding that baseline MS is most predictive of future MS growth suggests that competition should be managed prior to ACO entry and participation should be closely monitored in concentrated markets. With competition fostering quality and improving patient welfare, MS gains associated with hospital ACO participation may suggest the need for future assessments to ensure that quality and patient welfare do not decrease over time.</p>","PeriodicalId":50808,"journal":{"name":"American Journal of Managed Care","volume":"31 7","pages":"354-360"},"PeriodicalIF":2.5,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144709740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
