764. Patients with Substance Use Disorder Discharged from Safety Net Hospital to Skilled Nursing Facility for OPAT: Baseline Characteristics and Clinical Outcomes

BACKGROUND: Self-administered Outpatient Parenteral Antimicrobial Therapy (S-OPAT) is offered at Parkland Memorial Hospital for uninsured patients requiring an extended course of intravenous (IV) antibiotics to complete treatment at home.(1) At Parkland, S-OPAT has been demonstrated to be safe and effective with >70,000 inpatient bed days avoided to date, lower 30-day readmission rates, and significant cost savings.(1) Patients with a history of substance use are not eligible for S-OPAT and are discharged to skilled nursing facilities (SNF) to complete IV antibiotic therapy. This study aims to describe clinical outcomes of a patient population with history of substance use discharged to SNF for OPAT. METHODS: The electronic medical record was used to identify patients with substance use discharged to an SNF for OPAT between January 1, 2017 and April 30, 2018. Data were retrospectively reviewed for demographics, substance use history, treatment plan and clinical outcomes. RESULTS: 76 patients with history of substance use were discharged to SNFs for OPAT in the study period. 62% of patients reported non-IV drug use and 38% reported IV drug use (IVDU). The mean age for patients with non-IV drug use was 47 (83% male) vs. 43 years for patients with IVDU (86% male). Of patients with non-IV drug use, 30% reported cocaine use, 11% methamphetamine use and 59% polysubstance use or other. Of patients with IVDU, 38% reported heroin use, 10% methamphetamine use and 52% polysubstance use or other. When comparing outcomes of IVDU vs. non-IV drug use patients, 34% vs. 21% did not complete the prescribed treatment course, 28% vs. 11% left against medical advice (AMA), and 20% vs. 15% were readmitted to the hospital within 30 days. CONCLUSION: The majority of patients with substance use, 74%, completed their prescribed IV antibiotic course when sent to an SNF. However, a subset of these patients is at risk for poor clinical outcomes. A greater proportion of patients with prior IVDU compared with patients with prior non-IV drug use left treatment AMA and were readmitted to our hospital within 30 days of discharge. Future efforts to identify patients with substance use disorder who may be appropriate for S-OPAT with integration of addiction medicine services may improve clinical outcomes.
