How emergency department visits for substance use disorders have evolved during the early COVID-19 pandemic

OBJECTIVE: Higher opioid overdoses and drug use have reportedly occurred during the COVID-19 pandemic. We provide evidence on how emergency department (ED) visits for substance use disorders (SUD) changed in the early pandemic period. METHODS: Using retrospective data from January–July 2020 compared to January–July 2019, we calculated weekly 2020/2019 visit ratios for opioid-related, alcohol-related, other drug–related disorders, and all non-COVID-19 visits. We assess how this ratio as well as overall visit numbers changed after the mid-March 2020 onset of general pandemic restrictions. RESULTS: In 4.5 million ED visits in 2020 and 2019 to 108 EDs in 18 U.S. states, SUD visits were higher in early 2020 compared to 2019. During the peak-pandemic restriction period (March 13–July 31), non-COVID-19, non-SUD visits fell by approximately 45% early on, and then partly recovered with an average decline of 33% relative to 2019 levels. Visits for opioid-related, alcohol-related, and other drug–related disorders also declined, although less sharply, with an average drop of 17%, which was similar across SUD types. The visit ratios for 2020/2019 partially or fully recovered later in our sample period, depending on SUD type, but did not exceed early-2020 levels. However, substantial variation occurred across SUD types and across states. SUD visit declines were most prominent in the 65+ age group, except for alcohol-related visits where trends were similar across ages. SUD visits arriving by ambulance declined less or increased relative to self-transport visits, and ED deaths were rare. CONCLUSIONS: The 2020/2019 ratios of SUD ED visits fell substantially early in the COVID-19 pandemic, yet less than non-SUD, non-COVID ED visits. SUD ED visit ratios partly or fully recovered to 2019 levels by early June 2020, but did not exceed early 2020 ratios.
