1. Refine and implement a computerized surveillance and trigger tool to support medication therapy and risk management services. The ePRM tool will be used to (1) identify potential drug-therapy problems, which include quality, safety and cost-related problems; (2) select patients and providers for in-depth clinical reviews and possibly direct intervention (i.e., letter, phone call, Medication Therapy Management Services (MTMS), or Academic Detailing); (3) identify potential fraud and diversion of controlled substances; and (4) track patterns of medication use and evaluate ePRM performance, identify improvements, and direct policy change.
