Context: There are several scoring system in the literature to triage and predict prognosis of the patient using simple physiologic parameters. MEWS, REMS, RAPS are few among them. An appropriate scoring system is essential for risk stratification and hospitalisation in a busy Emergency Medicine department. Aims: We aim to compare the performance of MEWS, REMS, RAPS score in predicting mortality among the non-surgical patients presenting to the Emergency room. Settings and design: This prospective study was conducted in an ED of a teritary care hospital during a period of 2 months. Statistical analysis: ROC analysis was used to compare performance of all three scoring system in predicting mortality. Methods and materials: In this prospective study, all patients presenting to the ED with non-surgical complaints during a period of two months. MEWS, REMS, RAPS scores were calculated in the ED itself based on the physiologic parameters at the time of presentation. These patients were later followed up till discharge/death. Results: A total of 120 patients were included in our study, with mean age of 49.2±18.5. 60% of the study populations were males and 42.5% were females. The mortality in our study was around 16.7%. Though AUC of MEWS, REMS, RAPS were 0.73, 0.71, 0.69 respectively, but not significant difference were found between the three scoring system. Conclusion: All scores MEWS, REMS, RAPS performed equal in predicting in-hospital mortality among non- surgical patients presenting to the ED.
