Racial difference in quality for beneficiaries with cardiovascular disease or diabetes by provider group size. Black–white differences in six quality measures are displayed by the size of beneficiaries’ assigned provider group. Categories of provider group size are based on eligibility thresholds for participation in the Medicare ACO programs: small or ineligible for ACO programs (≤ 5,000 assigned beneficiaries); medium-sized or eligible for the Shared Savings Program but not for the Pioneer program (5,000–14,999 assigned beneficiaries); and large or eligible for the Pioneer program (≥ 15,000 assigned beneficiaries). Error bars indicate 95 % confidence intervals. ACSC = ambulatory care sensitive condition; DM = diabetes mellitus; CVD = cardiovascular disease; LDL = low-density lipoprotein.
