The pharmacist's role in overdose: Using mapping technologies to analyze naloxone and pharmacy distribution.

Objectives: To present preliminary research using geographic information system (GIS) mapping as a tool that can be integrated into pharmacy practice to increase access to and utilization of pharmacy-based interventions, including the distribution of naloxone.

Methods: Overdose death data was collected from medical examiner reports in an online database, and pharmacies carrying and distributing naloxone were determined by ZIP Code Tabulation Areas (ZCTAs) in Allegheny County, PA. The distribution of overdose death rates was analyzed in relation to naloxone-carrying pharmacies and all licensed pharmacies in the county with the use of GIS mapping.
