Accountable care organizations (ACOs) are the largest experiment in payment reforms, but the incentive structure may lead participating physician groups to select fewer vulnerable patients. In a new study in JAMA Network Open, my colleagues and I tested whether physician groups changed their proportions of black patients and patients with low socioeconomic status after joining the Medicare ACO, and found that – in general – they did not.
