Emergency Room Utilization and Methamphetamine Overdose Symptoms Among Syringe Services Program Participants in Washington State

Abstract

Background

Methamphetamine overdose can cause severe psychological and physical health issues including psychosis, heart attack, and death. People who use methamphetamine (PWUM) who experience methamphetamine overdose symptoms (MOS) are advised to seek emergency healthcare; however, factors related to seeking care are not well characterized.

Methods

This study used data from the 2021 Washington State Syringe Services Program (SSP) Health Survey, a cross-sectional survey administered to participants at 21 SSPs in Washington (N = 955). Participants answered questions related to substance use including emergency department/room (ER) utilization for methamphetamine use and whether they experienced psychological and physical MOS. Using Poisson regression, we assessed the association between ER utilization for methamphetamine use, non-fatal opioid overdose, and other key covariates among PWUM who experienced MOS.

Results

Methamphetamine use in the last three months was reported by 86% of participants. Among PWUM, 31% reported psychological MOS, 19% reported physical MOS, and 37% reported ≥1 MOS in the prior three months. Non-fatal opioid overdose (adjusted prevalence ratio [APR] = 2.04, 95% CI = 1.38–3.03), main drug of goofball (heroin and methamphetamine combined) (APR = 1.98, 95% CI = 1.34–2.92) and recent blood infection/sepsis (APR = 2.07, 95% CI = 1.24–3.46) were associated with ER utilization for MOS.

Conclusion

Among people who use SSPs in Washington State, methamphetamine use remains high, and MOS are common. Recent non-fatal opioid overdose was positively associated with ER utilization for methamphetamine use among PWUM who experienced MOS. Patients in the ER for MOS should be screened for opioid use disorder and linked with harm reduction supplies like naloxone and medications for opioid use disorder.
