Risk Factors Associated With In-hospital Substance Use Among People Who Use Methamphetamine in London, Ontario

In this secondary analysis, our objective was to identify risk factors for in-hospital substance use among people with a history of methamphetamine use and hospitalization in London, Ontario. Survey data from a total of 109 participants were collected between October 2020 and May 2021. Among our sample, 55.0% reported using substances during a hospitalization. Factors significantly associated with using substances while hospitalized included self-reported attention-deficit hyperactivity disorder (ADHD) [OR=3.15 (1.13, 8.77)], and accessing a social or medical service in the past six months [OR=2.26 (1.02, 4.99)]. In the multivariable model, factors significantly associated with using substances while hospitalized included white race [OR=3.24 (1.24, 8.45)], and self-reported ADHD [OR=3.98 (1.07, 14.8)]. We report a novel association between in-hospital substance use and ADHD, a common comorbidity associated with methamphetamine use. Identifying risk factors associated with in-hospital substance use is important in designing appropriate policies to prevent potential harm related to substance use during hospitalization.
