Derivation of a score to predict infection due to multidrug-resistant Pseudomonas aeruginosa: a tool for guiding empirical antibiotic treatment

•Multi-resistance is an emerging health problem that requires new approach strategies.•Pseudomonas aeruginosa infections have a high mortality rate and require a quick and effective approach.•The development of risk scores is a useful tool for the management of infectious pathology.•Antibiotic management in infectious diseases is a challenge for therapeutic success and for caring for the local ecology.
