Background: Due to high rates of mortality from pneumonia in the elderly, using a simple model for determining the prognosis of pneumonia can lead to a decrease in the mortality rate in this group. This study aimed to determine the validity of confusion, uremia, respiratory rate, blood pressure, and age ≥ 60 years (CURB-60) and confusion, respiratory rate, blood pressure, and age ≥ 60 (CRB-60) models in determining the prognosis of community-acquired pneumonia in the elderly and comparison them with models of the pneumonia severity index (PSI), CURB-65, and CRB-65.Methods: This cross-sectional study was conducted in 2013 in Arak University of Medical Sciences, Iran. Data of 141 patients with the age of 60 years and older with community-acquired pneumonia who had inclusion criteria were included in the study and analyzed. P-value < 0.05 was considered significant.Findings: The mean age of patients was 68.9 ± 7.6 with the median of 65.0 years. 76 patients (53.9%) were men and sex ratio of men/women was 1.17. 71.6% of patients were in urban areas. The most common comorbidity was cardiovascular disease (37.6%) and the most common sign and symptom were respiratory rale (92.2%), hypothermia or hyperthermia (88.7%), respectively. Sensitivity, specificity and positive predictive value of PSI and CURB-60 model for third day recovery were higher than the other models. The highest positive predictive value of intensive care unit (ICU) admission until the fourteenth day and 30-day mortality were in the models of CURB-65 and CRB-60.Conclusion: To determine the severity and prognosis of community-acquired pneumonia in the elderly, CURB-60 and CRB-60 models can be used.
