Brief Summary

Quasi-experimental intervention multicenter trial of patients treated with new antibiotics (before-after study).

The study will be carried out in 14 hospitals of the Andalusian Public Health System with representation from all the provinces and has been designed in two phases:

1. A first phase in which an observational study of historical preintervention cohorts of patients who have received either empirical or targeted treatment with ceftaroline, tedizolid, dalbavancin, ceftazidime-avibactam, ceftolozane-tazobactam and isavuconazole from January 2016 to December 2019 will be developed. Case detection will be carried out by locating the antimicrobial prescriptions in the electronic prescribing systems and / or pharmaceutical management systems of each hospital. A set of epidemiological, clinical, microbiological and prognostic variables will be completed in each case.

2. A second phase or intervention period that will be applied to the cohort of patients treated with new antibiotics (intervention cohort) from January 2020 to June 2021. A quasi-experimental intervention study will be carried out through the development of a Program for Optimizing the use of Antibiotics (PROA) in Spanish, Antimicrobial Stewardship Program (ASP) in English, in the participating hospitals. It will consist in the development of a consensus document on the use of new antibiotics following a Delphi methodology, dissemination of the consensus document / guide among the participating hospitals and audit on the prescription of new antimicrobials after the implementation of the guide based on providing non-imposition advice and positive reinforcement to the prescriber. The recommendations will be consigned in a structured form, which will allow to evaluate the degree of follow-up of the recommendations. The audit will be performed on day 0-1 of the prescription.

3. Cohort of bacteremia due to multiresistant microorganisms ("safety" cohort): In order to evaluate the safety of the use of new antimicrobials against therapeutic alternatives in syndromes where they are potentially a preferred option and parallel to the two phases, episodes for bacteremia by carbapenem-resistant Acinetobacter baumannii and Pseudomonas aeruginosa, carbapenem-resistant enterobacteria, vancomycin-resistant Enterococcus faecium and methicillin-resistant Staphylococcus aureus occurred in participating hospitals from 2017 to 2021 will be collected.
