Given that FFS reimbursement is incompatible with achieving the goals of the triple aim, the objective of this project is to research and develop a quantitative methodology to describe a comprehensive primary care payment model which supports it. This goal includes developing a prospective calculator which applies this methodology and models its expected impact. This study surveys the current state of value-based primary care payment models in use in the U.S. and draws key information about the efficacy, challenges, and successes of these programs. The resulting recommendations provide a framework and justification for critical components of a CPCP model.
