What is known and objective: Outpatient parenteral antibiotic therapy (OPAT) is an attractive option for patients who require parenteral antimicrobials as outpatients. Few OPAT studies have assessed the impact of IV antibiotic therapy via elastomeric continuous pumps, with most having been conducted outside the United States and few in county hospitals. The OPAT program in Harris Health system, the county hospital system of Houston, Texas, United States, has implemented a disposable elastomeric continuous infusion pump (eCIP) for self‐administered intravenous antibiotics (s‐OPAT) since December 2018. Our goal was to describe the clinical characteristics of patients discharged with an eCIP, as well as the safety and cost‐effectiveness of this pump. Methods: We retrospectively analysed patients discharged from Harris Health hospitals between 12/2018 and 02/2021 with s‐OPAT via eCIP at home. We extracted various patient characteristics and outcomes related to OPAT. Results and discussion: Among 481 OPAT patients during the study period, 91 patients received s‐OPAT via eCIP. A total of 1925 days of s‐OPAT were administered at home, with a median duration of 12 days. Eighty‐three patients (93.4%) achieved a cure from infection, six patients (6.6%) had side effects, and nine patients (9.9%) experienced 30‐day hospital readmission. Twenty‐two patients (24.2%) presented to the ED during s‐OPAT, with 13 patients (14.3%) presenting with PICC line concerns. We estimated that s‐OPAT via eCIP saved $2,360,500 to $3,503,900 compared to inpatient‐only therapy. What is new and conclusion: Our study showed that patients with s‐OPAT via eCIP had a high cure rate with a relatively low incidence of side effects and 30‐day hospital readmission. ED visits during therapy were relatively high, which indicates the necessity of close patient monitoring via the OPAT program. eCIP appears to be a good option to facilitate an early disposition of patients in county hospitals.
