Background: Prescription opioid abuse has increased to epidemic proportions in the United States. Kentucky, along with other states, passed comprehensive legislation to monitor and curb opioid prescribing.
Objectives: This paper characterizes patients who presented to the emergency department (ED) after abusing prescription opioids and heroin prior to and after the passage of House Bill 1 (HB1) in April 2012.
Methods: Based on a retrospective review of ED visits from 2009-2014 in one urban adult facility, patients were included if the chief complaint or diagnosis was directly related to prescription opioid or heroin abuse. The primary outcome is the number and type of substance abused by each ED patient.
Results: From 2009-2014, 2945 patients presented to the ED after prescription opioid or heroin abuse. The number of prescription opioid patients decreased from 215 (of 276 patients) in 2009 to 203 (of 697 patients) in 2014; 77.9% of patients abused opioids in 2009, vs. 29% in 2014 (a 63% decrease). The number of heroin patients increased from 61 in 2009 to 494 in 2014; 22% of patients in 2009 abused heroin, vs. 71% in 2014 (a 221% increase). Both piecewise regression and autoregressive integrated moving average trend models showed an increased trend in patient heroin abuse beginning in 2011-2012.
Conclusions: Our facility experienced a decrease in the number of patients who abused prescription opioids and an increase in the number of patients who abused heroin over the study period. The transition seemed to occur just prior to, or concurrent with, enforcement of statewide opioid legislation.
