ObjectiveOur objective was to explore evolving trends in US drug overdose mortality, overall and by age, sex, race, urbanization, and geography from 1999-2020.MethodsThis is a descriptive epidemiologic study. We used the US Centers for Disease Control and Prevention Wide-ranging Online Data for Epidemiologic Research and Multiple Cause of Death files from the National Center for Health Statistics. We used crude and age-adjusted cause of death and mortality rate ratios as measures of effects and 95% confidence limits to test for significance.ResultsFrom 1999-2020, drug overdoses caused 1,013,852 deaths and 4.3-fold increase in mortality rate ratios. Subgroup findings were sex (4.5 men, 4.0 women), race (4.6 White, 3.9 Black or African American, 4.0 Asian or Pacific Islanders, 5.1 Native Americans or Alaskan Natives), age (highest 5.6 in 25-34 years, lowest 1.1 in 75-84, and 0.77 in 85+), geography (highest 6.0 in Midwest, lowest 2.6 in West), and urbanization (highest 6.2 in non-metro, lowest 3.7 in metro).ConclusionsDrug overdoses in the United States from 1999-2020 increased 4.3-fold, with the highest increase in White and Native American or Alaskan Native populations, and Midwest and non-metro areas. The data create preventive and therapeutic challenges, including restrictions on pharmaceutical industries and enhanced efforts by health care providers in safer prescribing. Addiction care should be integrated into all clinical practices, regardless of specialty, and into undergraduate, graduate, and continuing medical education. Targeted interventions are needed to adequately assess patients and provide care. Analytic studies designed a priori are necessary to test hypotheses formulated from these data.Copyright © 2023 Elsevier Inc. All rights reserved.
