Abstract

Abstract

Objective: To determine diagnostic accuracy of BISAP in comparison to Ranson scores in predicting mortalities and severities in patients with acute pancreatitis coming to the emergency department.

Methods: Cross-sectional study conducted in Department of Emergency Medicine, Aga Khan University Hospital, Stadium road Karachi, Pakistan. 136 patients were selected via non-probability consecutive sampling technique, those who fulfilled the criteria of inclusion. BISAP score was applied in the emergency department (ED) & the patients were followed in ward/intensive care unit where Ranson scores were calculated in the following 48 hours. Both the scores were calculated and compared for the prediction of severity and mortality for each patient. All the obtained data was recorded in Performa.

Results: In this study 136 patients, who fulfill the inclusion criteria were selected. On the basis of BISAP and Ranson score; mild acute pancreatitis to moderate acute pancreatitis (MAP to ModAP) was diagnosed in 123 (90.4%) and 119 (87.5) patients and severe AP (SAP) in 13 (9.6%) and 17 (12.5%) patients respectively. Specificity (Sp) 94.62% vs 91.54%, Sensitivity (Sn) 100.0% vs 100.0%, negative predictive value (NPV) 100.0% vs 100.0%, positive predictive value (PPV) 46.15% vs 35.29% and diagnostic accuracy (DA) 94.85% vs 91.91% of BISAP vs Ranson scores respectively.

Conclusion: It was concluded from the study that BISAP and Ranson score are very reliable tool for identification of acute pancreatitis patients at higher risk of severity and mortality. BISAP and Ranson score has same sensitivity but BISAP score has higher specificity than Ranson score.
