Background. Patients with opioid use disorder (OUD) are frequently admitted for invasive infections. Medications for OUD (MOUD) may improve outcomes in hospitalized patients. Methods. In this retrospective cohort of 220 admissions to a tertiary care center for invasive infections due to OUD, we compared 4 MOUD treatment strategies: methadone, buprenorphine, methadone taper for detoxification, and no medication to determine whether there were differences in parenteral antibiotic completion and readmission rates. Results. The MOUDs were associated with increased completion of parenteral antimicrobial therapy (64.08% vs 46.15%; odds ratio [OR] = 2.08; 95% CI, 1.23-3.61). On multivariate analysis, use of MOUD maintenance with either buprenorphine (OR = 0.38; 95% CI, .17-.85) or methadone maintenance (OR = 0.43; 95% CI, .20-.94) and continuation of MOUD on discharge (OR = 0.35; 95% CI, .18-.67) was associated with lower 90-day readmissions. In contrast, use of methadone for detoxification followed by tapering of the medication without continuation on discharge was not associated with decreased readmissions (OR = 1.87; 95% CI, .62-5.10). Conclusions. Long-term MOUDs, regardless of selection, are an integral component of care in patients hospitalized with OUDrelated infections. Patients with OUD should have arrangements made for MOUDs to be continued after discharge, and MOUDs should not be discontinued before discharge.
