Patient selection and exclusions for control and Transition-of-Care Outpatient Parenteral Antibiotic Therapy (TOC-OPAT) groups. For the control group, 431 patients age 18 and older who were discharged from the hospital to their home or a skilled nursing facility from January 1, 2015 to June 30, 2015 and received intravenous (IV) antibiotics after discharge were identified retrospectively using Clinical Looking Glass software (Emerging Health Information Technology, Yonkers, NY). Of those, patients were excluded if they did not receive an Infectious Diseases (ID) consult before hospital discharge to assess the appropriateness of outpatient IV antibiotics (n = 246) or were transferred to an outside hospital or to the inpatient rehabilitation (rehab) unit (n = 1). The remaining 184 patients were included in the control group analysis. For the TOC-OPAT group, 179 patients (all age 18 or older) were referred to the program by inpatient ID providers and subsequently discharged from the hospital to their home or a skilled nursing facility between July 1, 2015 and February 29, 2016. Of those, patients were excluded (1) if they did not receive any antibiotics (n = 5) or exclusively oral antibiotics (n = 26) after discharge or (2) if they were transferred to an outside hospital or the inpatient rehabilitation unit (n = 2). The remaining 146 patients were included in the TOC-OPAT group analysis.
