Attribution in DSRIP Demonstration Programs: A Spotlight on New Jersey and New York

The brief has three objectives: (1) to describe how DSRIP demonstrations handle attribution and to discuss the differences and commonalities in their methods, (2) to report on New Jersey’s and New York’s experiences developing and implementing an attribution method, and (3) to provide insights on factors that promote or hinder success for future DSRIP demonstrations—or other programs focused on delivery system redesign—and forthcoming DSRIP evaluations. We chose New Jersey and New York for case studies because these demonstrations have operated long enough for administrators and providers to offer insight on attribution methods, including challenges to and facilitators of implementation. The demonstrations also explicitly include the uninsured population, which will shed light on important considerations for this population in terms of attribution, performance measurement, and payment.
