Abstract

Background: Community-acquired pneumonia (CAP) refers to pneumonia attained outside the hospital or less than 48 hours be-fore admission, which is a significant cause of mortality and morbidity, especially in major comorbidities and older age. Several microorganisms contribute to developing CAP, primarily Streptococcus pneumonia, Haemophilus influenza, Moraxella catarrhalis, and atypical pathogens, e.g., Mycoplasma pneumonia. The incidence of these microorganisms depends on outpatient or inpatient set-tings. Administering appropriate treatment among available antibiotics is a critical issue affecting patient survival. Methods: With a multidisciplinary panel expert, this document offers evidence-based recommendations for managing CAP in Iran.Results: The document evaluated the availability of antimicrobial agents and local antibiotic resistance patterns based on 94 rele-vant published studies from Google Scholar, Scopus, PubMed, Scientific Information Database (SID), Iran Medex, Iran doc, Mag Iran, PubMed, and expert opinions.Conclusions: The panel addressed two main parts of rational recommendations for managing outpatients or hospitalized patients with CAP.
