title: An evaluation of Oregon's evidence-based Practitioner-Managed Prescription Drug Plan.
abstract: This paper describes Oregon's implementation of its publicly developed, evidence-based, Practitioner-Managed Prescription Drug Plan (PMPDP). Oregon's PMPDP was initially self-enforced with a dispense as written (DAW) exception process, followed by an educational prior authorization (soft PA) method, and finally no active enforcement. Market-share trends indicate that the educational prior authorization process was most effective at increasing the use of preferred agents. Pharmacy costs decreased 9.1 percent and 17.7 percent after implementation of the DAW and soft PA policies, respectively. Data from nonenforced PMPDP classes showed no change; this suggests the need for effective methods to encourage PMPDP compliance.
