India being a developing country with transitional healthcare system it is essential to prioritize the severely ill Community Acquired Pneumonia to make an optimal usage of limited resources that are available. The aim is (1) To evaluate the ability of the CURB–65 Score to stratify patients into different management groups; to correlate CURB–65 score to 48 hour and 30 day mortality & to relate mortality with association of comorbid illness and smoking. Prospective observational study, sample size is 72, simple random sampling method. The data was collected using pre–structured questionnaire and checklist to estimate CURB–65 score and has been analysed and presented in the form of frequency tables, proportions, pie–charts and bar graphs wherever necessary; p value has been calculated. Among total 72 cases, 27 (37.5%) cases were having CURB–65 score 0–1 (Mild), 27 (37.5%) cases with score 2 (Moderate) and 18 (25%) cases with score 3–5 (Severe); CURB–65 score > 3, co–morbidities like COPD had a statistically significant association with higher mortality whereas co–morbidities like asthma, tuberculosis and habit of tobacco smoking were falling short of statistical significance. Most common (56.6%) causative agent of CAP isolated was Pneumococcus. The CURB –65 score is an effective tool to classify CAP cases into different management groups & prioritize the severe CAP cases for ICU admission or using ventilator facilities.
