Estimating the Value of Aztreonam-Avibactam in Treating Metallo-beta-Lactamase-Producing Enterobacterales Infections in Spain Using the STEDI AMR Value Framework.

ABSTRACT:

Introduction

Treatments for serious infections caused by multidrug-resistant gram-negative bacteria, including metallo-β-lactamase-producing Enterobacterales (MBL-EB), are limited and aztreonam with avibactam (ATM-AVI) is the first β-lactam/β-lactamase inhibitor combination active against MBL-EB approved in Europe and approved for reimbursement by the Spanish National Health System (NHS). This study aims to estimate the value of adding ATM-AVI as a new first-line treatment into the current strategy (ATM-AVI → cefiderocol → colistin + meropenem) in patients with hospital-acquired/ventilator-associated pneumonia (HAP/VAP) and complicated intra-abdominal infections (cIAI), caused by MBL-EB from the Spanish NHS perspective.
