Monotherapy vs Combination Therapy for Bone Infections Caused by Pseudomonas Aeruginosa

Centre Hospitalier de Saint-Denis300 enrolled

Overview

This study looks at how well one antibiotic (monotherapy) works compared to two antibiotics (combination therapy) in treating bone infections caused by Pseudomonas aeruginosa. It includes 300 adult patients who had this type of infection confirmed by lab tests and medical imaging. The goal is to find out if using just one antibiotic is as effective as using two, while also looking at side effects, the need for more surgery, antibiotic resistance, and overall antibiotic use.
