Effect of Implementation of PDMP

"Our analysis showed that the implementation of a province-wide centralized prescription network was associated with large, immediate and sustained reductions in filled prescriptions for opioid analgesics and benzodiazepines deemed inappropriate by our definition. These findings provide empirical evidence that centralized prescription networks can reduce inappropriate prescribing and dispensing of prescriptions by offering health care professionals real-time access to prescription data. Physicians did not have access to PharmaNet when it was first introduced; consequently, the reductions observed in our study likely reflect the availability of real-time prescription information to front-line pharmacists."
