Of the 229 patients with microbiologic results, details regarding possible drug use were available in 227 patients. Patients with no documented history of drug use were categorized as non-PWUD, while patients who use drugs (PWUD) were separated based on whether drug use was active or not. Patients with prior histories of injection or noninjection drug use were categorized as nonactive PWUD, while those with injection or snorting drug use reported in the past 3 months were categorized as active PWUD. Thirty-nine percent of patients with spinal epidural infection had substance use disorder. Most patients with monomicrobial cultures were infected with gram-positive, aerobic bacteria (86%). Active PWUD were more likely to have methicillin-resistant Staphylococcus aureus compared to non-PWUD (36% vs 13%, respectively, P = .002). Nonactive PWUD were more likely to have non\u2013Escherichia coli gram-negative bacterial infections than non-PWUD (18% and 4.4%, respectively, P = .01).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>More than 1 in 3 patients with a spinal epidural infection unrelated to recent surgery had substance use disorder.
