Abstract

Several state Medicaid programs have aggressively elected to pursue development of the PCMH model—some elected to do so before adequate outcome evidence was available to support the concept. But the PCMH model offered a repackaging on something for which many Medicaid programs are familiar—process measures. Doing so builds on the myth that if the payer can just exactly measure processes, there will be some assurance that outcomes can be improved and costs reduced. The evidence shows neither assumption to be correct.
