Performance in the Medicare Shared Savings Program after accounting for nonrandom exit: an instrumental variable analysis.
The purpose of this study was to evaluate the effect of the Medicare Shared Savings Program (MSSP) on spending and quality while accounting for clinicians' nonrandom exit. MSSP ACO participants were compared with control beneficiaries using adjusted longitudinal models that accounted for secular trends, market factors, and beneficiary characteristics. Results showed that, after adjustment for clinicians' nonrandom exit, the MSSP was not associated with improvements in spending or quality. Selection effects, including exit of high-cost clinicians, may drive estimates of savings in the MSSP.
