Using Geographic Information System Analysis to Understand West Virginia’s Growing Opioid-Overdose Epidemic - What Are We Missing?

Abstract

Introduction:

The opioid epidemic is overwhelming communities across the United States. West Virginia (WV) has been devastated, heralding a 86% increase in deaths from 2012-2016, and over 1,000 deaths last year as per WV Health Statistics Center. Treatment centers and providers have emerged throughout the state to provide medication-assisted treatment (MAT). The impact of these clinics on the opioid abusing population is not yet fully understood.

Aim:

Utilizing Geographic Information System (GIS), a comparison of MAT provider locations versus regions of historical overdoses can indicate areas of deficiency. If no providers emerge in underserved counties, overdose deaths in those areas will continue to rise.

Methods:

Maps were created using current DEA-X licenses in WV registered through Substance Abuse and Mental Health Services Administration (SAHMSA). Overdose death rates were taken from WV Public Health Records from 2010-2017. Two maps and corresponding data were compared for overlap or lack thereof.

Results:

Of the 338 locations of DEA-X licenses registered, 17.5% are in Cabell County, which led the state in overdose deaths in 2017. Only 2.5% of the total providers are currently in Wayne County, which had the second highest overdose death rate. Berkeley County, which was 3^rd highest, has a mere 6.5% of total providers. Comparatively, Kanawah County, home to the state’s capital, has over twice this number of providers despite consistently having at or below the state average of overdose rates. Resources are pulled towards population-dense areas or university centers, where the epidemic is present but misses counties with higher overdose rates.

Discussion:

Results show a lack of MAT providers in many of WV’s devastated counties. Treatment centers exist throughout the state but are concentrated in regions with large cities or academic centers. This distribution limits accessibility to a marginalized patient population, making improvements unlikely in WV’s future opioid-overdose death rates.
