Epidemic Fentanyl Deaths in Maryland: A Public Health Intervention Involving Geographic Information Systems and Collaboration with the Drug Enforcement Administration

Abstract

An ongoing epidemic of illicit fentanyl overdose deaths started in Maryland in July 2013. The records of the Office of the Chief Medical Examiner for the state of Maryland were searched to identify these deaths from July 2013 to February 2015. A geographic information system was used to map and analyze the spatial and temporal distribution of the deaths in Maryland. A total of 266 fentanyl-related deaths were identified. The number of deaths per month generally increased from July 2013 to June 2014, decreased precipitously in August 2014, and rose steadily until the end of the study in February 2015. Deaths began in Baltimore City and then spread throughout the state. A statistically significant cluster (“hot spot”) of deaths was centered in Baltimore City. Greater death densities were also centered on other cities. A high-density band of deaths extended from Baltimore City towards Annapolis. Deaths extended past cities and into the surrounding suburbs; this effect was most pronounced around Baltimore City. Deaths in Baltimore City appeared concentrated in certain neighborhoods. However, the activity moved between various neighborhoods over the course of the study. Review of the above data with the United States Drug Enforcement Administration's Baltimore Office (DEA) allowed some of the above trends to be explained in terms of illicit drug production, transportation and distribution. The DEA is implementing a new strategy to combat illicit narcotic distribution and use in Maryland.
