Introduction:

Antimicrobial resistance is one of the main world public health problems. It represents an important cause of morbidity in general population and a high cost for health systems. Community Acquired Pneumonia (CAP) represents one of the main bacterial infections in our midst.

Objective:

To evaluate the adequacy of the Antimicrobial Stewardship (AMS) in the management of CAP in the Emergency Department of Hospital de Clínicas (HC) between July and August 2019.

Materials and methods:

An observational, cross-sectional study was conducted from July-August 2019, in the Emergency Department of Hospital de Clínicas. Patients older than 18 years old were included, who signed the informed consent, diagnosed with CAP, fulfilling clinical and imaging criteria established in the flowchart. A database designed from the AMS flow chart of the Hospital de Clínicas was developed.

Results:

51 patients were included for the analysis. The average age was 54 years, 28 were women. The most prevalent comorbidities were smoking, consumption of cocaine paste or alcoholism, present in 51% of the sample. Thirty-five patients presented severity criteria, prevailing respiratory failure in 71%. Risk factors for multiresistant microorganisms was 43%. PROA adequacy of 41.2% was observed. Discussion: The adequacy to the recommended treatment was lower than that described in other papers. The main problem was an erroneous classification in the risk groups proposed in the flowchart, causing hospitalization of patients who had to receive treatment at home, receiving broader spectrum antibiotic therapy. Conclusions: The existence of hospital stewardships allows monitoring of diagnostic practices and antimicrobial prescription. Inadequate application of the flow chart was observed, which determined the use of broader spectrum antibiotics with potential risk of developing resistance.
