Abstract
Introduction: Community acquired Pneumonia (CAP) is a common respiratory disease and a common health problem that causes many deaths annually and has burden of costs on health care system. Prognostic factors can be used for assessing and treating patients with CAP. The aim of the present study was to evaluate prognostic factors and outcome of patients hospitalized with CAP in infectious diseases centers. Methods: In a retrospective-descriptive study, 236 patients with CAP who referred to Imam-Reza and Sina hospitals of Tabriz University of Medical Sciences, Tabriz, Iran, during 2011-2013, were studied. Age, sex, comorbidities, rate of mortality, and laboratory results of patients were evaluated. P value considered statistically significant when ≤ 0.05 for statistical analysis. Results: The mean age of patients was 68.7 ± 18.9 years, and male to female ratio was 1 to 1.02. The mean duration of hospitalization was 8.0 ± 4.6 days and mortality rate of patients was 11.9%. Increase in heart rate (r = 0.406, P = 0.001), and respiratory rate of patients (r = 0.154, P = 0.018), pleural effusion (r = 0.313, P = 0.001), increase in blood urea level (r = 0.271, P = 0.001), and increase in creatinine level (r = 0.226, P = 0.001), had significant correlation with mortality rate of patients. Conclusion: Based on the findings of the present study, heart rate, respiratory rate, pleural effusion, blood urea level, and creatinine level had significant correlation with mortality rate of patients with CAP. Lung disease, heart disease, and diabetes were the most common comorbid conditions in these patients.
