Brief Summary

Background: Community-acquired pneumonia (CAP) continues to be a major health problem with significant mortality and it's one of the main causes of antibiotic prescription. Antibiotic overuse is a key driver of antimicrobial resistance and exposes patients to an increased risk of other antibiotic-related adverse events. The investigators aim to assess if rapid molecular tests are an effective tool to reduce antibiotic use in CAP compared to routine microbiological testing.

Design: Randomized, controlled, open-label clinical trial with two parallel groups (1:1) settled in a two-year multicenter, two tertiary care hospitals, between 2019 and 2021. Eligible participants will be non-severely immunosuppressed adult patients hospitalized for CAP through the emergency department. Primary endpoint will be antibiotic consumption measured by days of antibiotic therapy (DOT) per 1000 patient-days. Secondary end points will be: de-escalation to narrower antibiotic treatment, time to switch from intravenous to oral antibiotics, antibiotic-related side effects, length of hospital stay, days until clinical stability, need for ICU admission, need for hospital readmission in the 30 days after randomization, death from any cause in the 30 days after randomization. Patients will be randomly assigned to receive experimental diagnosis (comprehensive molecular testing added to routine microbiological testing) or standard diagnosis (only microbiological routine testing). A total of 220 patients are estimated in the experimental arm (undergoing comprehensive molecular testing) and 220 control subjects (undergoing routine testing) to be able to reject the null hypothesis that experimental and control groups have equal DOT per 1000 patients-days with a probability above 0.8.

Discussion: Comprehensive molecular tests could be a key tool in the optimization of etiological diagnostics in CAP and, therefore, a key element in antimicrobial stewardship programs developed to improve safety and antibiotic use in CAP.
