Abstract Background Patients with serious bacterial infections (SBI), identified as bone and joint infections (BJI), bacteremia/endocarditis, and central nervous system (CNS) infections are frequently discharged on outpatient parenteral antimicrobial therapy (OPAT). They account for 48% of all infections treated in our network of Infectious Disease (ID) physician office infusion centers (POICs). Care for these patients poses risks and challenges to ensure safe and successful outcomes while avoiding hospitalizations. This study examines clinical outcomes and complications of our SBI patients receiving OPAT in ID POICs. Methods All patients were identified with SBI receiving OPAT in 2017 from 14 POICs. A group of 250 patients were randomly selected by incidence of diagnosis and a retrospective chart review performed. Demographics, treatment regimen, clinical outcomes, adverse drug reactions (ADRs) and unplanned hospitalizations during OPAT were collected. Clinical success was defined as clinical cure or improvement at completion of OPAT. Patients were included who were hospitalized for <7 days and subsequently completed OPAT. ADRs leading to hospitalization or discontinuation of OPAT were deemed serious. Descriptive statistics were used for distribution of variables. Results SBI patients included BJI (n = 175), bacteremia/endocarditis (n = 60) and CNS infections (n = 15) as described in Table 1. Successful clinical outcomes were reported in 224 patients (89.6%) after a mean duration of OPAT of 32±20 days. Of these, 15 patients (6.7%) were hospitalized during OPAT and returned to the POIC for a successful clinical outcome. Clinical success rates for BJI, bacteremia/endocarditis and CNS infections were 89.1%, 91.6% and 86.7%, respectively. The primary reason for nonfavorable outcomes was worsening of infection (15/26, 58%). Serious ADRs were reported in 12 patients (4.8%) with 6 (2.4%) leading to hospitalization. Unplanned hospitalizations during OPAT occurred in 33 patients (13.2%) with the majority (21/33, 64%) related to disease. ADRs and hospitalizations compare favorably to data previously reported. (Schmidt et al. OFID 16.4, 2017). Conclusion Patients with serious bacterial infections had high success rates when treated by an ID physician in infusion centers. Adverse events and unplanned hospitalization rates were low. Disclosures All authors: No reported disclosures.
