Overview
The goal of this multicentre observational study is to analyse the treatment strategies and the outcomes for patients with S. maltophilia infections using target trial emulation methodology. The main question it aims to answer is:
• Does combined therapy achieve better results than monotherapy in treating S. maltophilia infections?
Researchers will compare groups receiving monotherapy and combined therapy to see if there are differences in all-cause 30-day mortality.
