Unadjusted Rates and Leakage of Overall Specialty Visit Use Among Most Specialty-Oriented ACOs
Abbreviations: Accountable care organization (ACO), Medicare Shared Savings Program (MSSP).
Trends in unadjusted new specialist visit rates per 100 beneficiaries in each MSSP cohort are shown for ACOs with the highest specialty orientation with >48% specialist physicians in their contract (1st [highest] quartile of specialty orientation), broken down into inside ACO visits (orange) and outside ACO visits (blue). “Leakage” is defined as the proportion of inside ACO visits over all new specialty visits in a given year.
