Local Health Department Activities to Reduce Emergency Department Visits for Substance Use Disorders.

The Affordable Care Act (ACA) provides financial incentives to prevent substance use disorders (SUDs). Local health departments (LHDs) can receive funds to establish care teams that partner with primary care providers and health systems. This study estimates the potential effect of LHDs on emergency visits for SUDs, using linked data sets from the Healthcare Cost and Utilization Project Emergency Department (ED) sample for the State of Maryland-2012, the National Association of County and City Health Officials Profiles Survey 2013, and Area Health Resource File 2013 to estimate potential effect of LHDs' provision of SUD preventive care and SUD-related policy implementation. Local health department involvement in SUD-related policy during the past 2 years and provision of preventive care for behavioral health in the past year significantly reduced the probability of having a SUD-related ED visit by 11% and 6%, respectively, after controlling for individual characteristics (odds ratio [OR] = 0.89, p < .001; OR = 0.93, p < .001). After adjusting for the individual and contextual factors, LHD involvement in policy was still associated with 14% reduction in SUD-related ED visits (OR = 0.86, p < .001). Results offer insights on the extent to which the LHD activities can possibly affect SUD-related ED visits and provide a foundation for future work to identify effective LHD interventions.
