788. Outcomes of Multidisciplinary Care Conferences for Patients with Substance Use Disorders Requiring Prolonged Antimicrobial Therapy for Severe Infections

BACKGROUND: Infectious complications in people with substance use disorders (SUD) are rising, and while outpatient parenteral antimicrobial therapy (OPAT) is widely used in the general population, OPAT failure rates in SUD are high. Due to perceived PICC risks and OPAT safety, serious infections in people with SUD at our institution often resulted in hospitalization for the duration of treatment. Prolonged inpatient treatment is difficult to tolerate and increases healthcare costs. Our OPAT and addiction medicine teams initiated multidisciplinary discharge planning conferences (OPTIONS-DC) for inpatients with SUD requiring prolonged antimicrobials. The goal was to prioritize patient preferences regarding OPAT setting while incorporating harm-reduction principles. The goal of this study is to assess the impact and outcomes of the OPTIONS-DC. METHODS: We prospectively recorded comprehensive notes at OPTIONS-DC and retrospectively performed chart review for conferences held from February 2018 to March 2019.We performed a content analysis of OPTIONS-DC notes and patient records to identify ways that OPTIONS-DC modified care plans and prioritized patient preferences. RESULTS: Thirty-one conferences were held during the study period. Twenty-eight patients reported substance use within 90 days, 24 used intravenous substances, 12 were homeless, 24 had a mental health diagnosis, and 20 started medication-assisted treatment during hospitalization (Table 1). For 16 patients the conference altered the definitive treatment plan to align with patient preferences while emphasizing safety, and 13 of those were changed to an outpatient setting. A total of 10 patients had a decreased length of stay, with a total of 238 hospital days saved overall. OPAT was planned at discharge for 15 patients, 11 of whom completed their OPAT course. Overall, 21/31 (68%) completed their recommended antimicrobial course and 3 were lost to follow-up. CONCLUSION: A multidisciplinary conference that prioritizes patient preferences and uses harm reduction strategies to optimize infection treatment plans is feasible and effective. The OPTIONS-DC model has potential to expand treatment options for infections in SUD, reduce hospital days, and may serve as an example for other institutions.
