Efficacy, Safety, and Cost-Effectiveness Analysis of Ceftazidime-Avibactam versus Polymyxin B in the Treatment of Carbapenem-Resistant Enterobacteriaceae Infections: A Target Trial Emulation.

ABSTRACT:

Introduction

Treatment options for carbapenem-resistant Enterobacteriaceae (CRE) infections are limited, with polymyxin B (PMB) and ceftazidime-avibactam (CZA) being among the available choices. However, research on these options is scarce and significantly heterogeneous. This study aims to analyze the efficacy, safety, and cost-effectiveness of PMB and CZA within a standardized target trial emulation (TTE) framework.

Methods

This retrospective study emulated a target trial to evaluate the efficacy, safety, and cost-effectiveness of CZA versus PMB for treating CRE infections. Conducted at Nanjing Drum Tower Hospital, this study included adult patients treated with CZA or PMB from July 2020 to December 2022. Data on demographics, treatment outcomes, and costs were collected.
