Are Rural Opioid Treatment Program (OTP) Facilities Associated with Lower Deaths?

Objectives: Rural areas have been particularly affected by the opioid epidemic in the U.S., with treatment options being scarce. This study focuses on opioid treatment programs (OTPs), which combine counseling services and opioid-related medication provision. In the South census region (comprised of 16 states and D.C.), 156 urban counties and 27 rural counties contained OTPs as of 2013. We examine whether their presence is associated with lower opioid-related death rates during 2014-2016. Methods: Coarsened exact matching (CEM) is used to match treated and untreated counties on demographic characteristics and opioid-related deaths from 2011 to 2013. Two treatments are considered: (1) if a county had an OTP in 2013; and (2) if an OTP existed in a neighboring county in 2013. The matched samples are then used in weighted least square regression models, with propensity score matching serving as a robustness check. Rural and urban counties are analyzed separately to determine if the impact of OTPs differs between these areas. Results: Results show that the presence of an OTP mostly has no statistical association with the rate of (or change in) future opioid deaths, in either rural or urban counties. Proximity to a neighboring county OTP displays a similar lack of association. Conclusions: The findings suggest that OTPs are not associated with fewer opioid-related deaths in the South over the near term, regardless of rural or urban location. These results could be attributed to outside factors that hinder this relationship. Continued assessment of varied approaches to the rural opioid crisis is encouraged.
