Clinical Outcomes of Piperacillin/Tazobactam Treatment in Outpatient Parenteral Antimicrobial Therapy (OPAT) Programs: Comparison of Two Models of Opat Care.

ABSTRACT: Objectives: Piperacillin/tazobactam (P/T) is a broad-spectrum β-lactam antibiotic frequently used in outpatient parenteral antimicrobial therapy programs (OPAT). We aim to compare the clinical outcomes of P/T treatment in two models of OPAT care in order to maximize the utilization of health resources. Material and methods: We conducted a prospective observational study with retrospective analysis of a cohort of patients treated with P/T delivered every 24 or 48 h in an OPAT program. The primary outcomes were treatment failure during the OPAT episode and 30 day treatment failure. A bivariate and multivariate logistic regression model was built. A two-sided p < 0.05 was considered statistically significant. Results: Between 2012 and 2022, 247 patients were treate
