Abstract
BACKGROUND: In the United States, drug overdose mortality has increased. Death records categorize overdose deaths by type of drug involved, but do not include information about the route of drug administration. METHODS: We utilized data from drug treatment admissions (Treatment Episodes Dataset, TEDS-A) and National Vital Statistics Systems to estimate the percentage of reported drug overdose deaths that were injection-involved from 2000 to 2018 in the U.S. Data on reported route of administration at admission were used to calculate the percent injecting each drug type, by demographic group (race/ethnicity, sex, age group) and year. Using the resulting probabilities, we estimated the number of overdose deaths that were injection-involved. Estimates were compared across drug types, demographic characteristics, and year. FINDINGS: The number of overdose deaths among adults increased more than 3-fold from 2000 (n = 17,196) to 2018 (n = 67,021). During that timeframe, the number of estimated injection-involved overdose deaths increased more than 8-fold from 2000 (n = 3467, 95% CI: 3449-3485) to 2018 (n = 28,257, 95% CI: 28,192-28,322). From 2000-2007, the percent of overdose deaths that were injection-involved remained stable around 20%. From 2007-2018, the percent of overdose deaths that were injection-involved increased from 18.4% (95% CI: 18.3-18.6%) to 42.2% (95% CI: 42.1-42.3%). In 2018, most estimated injection-involved overdose deaths were due to injecting heroin/synthetic opioids (n = 24,860, 95% CI: 24,800-24,919), which accounted for 88.0% of all injection-involved deaths. CONCLUSIONS: Much of the recent increase in overdose mortality is likely attributable to rising injection-involved overdose deaths.
