Intro: This study aimed at evaluating healthcare-related sepses caused by three multi-drug resistant Gram-negative bacteria (Acinetobacter baumannii, Klebsiella pneumoniae and Pseudomonas aeruginosa) in a tertiary hospital in 2018-2020, particularly concerning therapy, antibiotic-resistance and outcomes, by also comparing the pre-COVID (2018-2019) and COVID (2020) periods. Methods: An observational, retrospective-cohort analysis was based on data related to patients admitted to the “SS. Antonio e Biagio e Cesare Arrigo” Hospital in Alessandria (Italy) between 2018 and 2020, with septic episodes from bacteria of the examined species, whose antibiogram proved resistance to ≥ 2 antimicrobial classes indicated by the European Centre for Disease Prevention and Control. Data were retrieved from patients’ medical records and the hospital's computer-based application. Statistics involved Fisher-test comparisons and cumulative incidence analyses. Findings: Inclusion criteria led to enrolment of 174 patients. Comparison between 2020 and 2018-2019 showed a relative increase in A. baumannii cases, at the expense of the other species (p
