Risk Stratification of Patients with Community Acquired Pneumonia Presenting to Emergency Room and Prediction of Mortality Based on Severity Scores

Community-acquired pneumonia (CAP) is defined as acute pulmonary infection in a patient, who is not hospitalized or residing in a long-term care facility for 14 or more Days before presentation. CAP is one of the most common infectious diseases addressed by clinicians and is an important cause of mortality and morbidity worldwide Pneumonia is one of the leading causes of death and morbidity, both in developing and developed countries and is the commonest cause (10%) of hospitalization in adult and children. Estimates of the incidence of community-acquired pneumonia range from 4 million to 5 million cases per year, with about 25% requiring hospitalization. Community-acquired pneumonia refers to pneumonia acquired outside of hospitals or extended-care facilities. It is important to risk stratify patients with pneumonia to look for morbidity and mortality. Objectives of study was to risk stratify the patients with community acquired pneumonia in the emergency room using CURB-65 score, SOFA score, QSOFA score, PSI score. All patients with community acquired pneumonia after application of the Inclusion and exclusion criteria were involved in the study. The clinical data with clinical Examination findings, investigations, clinical severity score, treatment, outcome were entered into a structured Performa. The patients were followed up for 28 days from the time of discharge. In our study we found that PSI and QSOFA score predicted mortality with p value of <0.001 which is highly sensitive compared to other scores.
