Evaluation of the Frequency of Antibiotic Stewardship for the Treatment of Pneumonia in a Tertiary Hospital (Loghman Hakim Hospital) in 2021

Background: Pneumonia is one of the common infectious diseases in the community and hospital, which can cause complications and death if not treated. Correct treatment of this disease is important. Therefore, in this study, we aimed to evaluate antibiotic stewardship for pneumonia with the American Thoracic Society (ATS) guidelines in Loghman Hakim Hospital in 2021. Materials and Methods: In this descriptive study, all patients admitted to Loghman Hakim Hospital in 2021 with pneumonia were evaluated. Age, gender, type of pneumonia (healthcare-associated pneumonia, community-acquired pneumonia, community-acquired aspiration pneumonia, early-onset and late-onset hospital-acquired pneumonia, ventilator-associated pneumonia, and hospital-acquired aspiration pneumonia), antibiotic type and dose, and renal dose adjustment of antibiotics were recorded. Then, the antibiotic prescription protocol in patients with pneumonia was compared with the ATS guidelines. Results: 72 people were included in the study; 11 (15.28%) had healthcare-associated pneumonia (HCAP), 24(33.33%) community-acquired pneumonia (CAP), 20(27.78%) community-acquired aspiration pneumonia (CAAP), 7(9.72%) hospital-acquired pneumonia (HAP), 4(5.56%) hospital-acquired aspiration pneumonia (HAAP), and 6 (8.33%) patients had ventilator-associated pneumonia (VAP). 31.94% did not receive antibiotics according to the protocol. 13.88% of patients received antibiotics correctly, but with the wrong dose, and in 18.06% of patients, the type of antibiotic was wrong (P-value=0.102). Conclusion: Monitoring antibiotic stewardship in the hospital for patients with pneumonia is necessary.
