A Hospital Based Comparative Study of Bedside Index for Severity in Acute Pancreatitis (BISAP) Score and CT Severity Index Score (CTSI) in Acute Pancreatitis Patients at Newly Established Tertiary Care Center

Background: Severe acute pancreatitis (SAP) is a life-threatening condition with organ failure, pancreatic necrosis, infections, and death. Multiple factors scoring systems are used for triage decisions to manage acute pancreatitis according to severity. The aim of this study is to compare the prognostic value of Bedside Index for Severity in Acute Pancreatitis (BISAP) score and CT severity index (CTSI) score in estimating the clinical results and degree of acute pancreatitis in patients. Material and Methods: Forty patients at a tertiary care facility with acute pancreatitis were enrolled in this prospective observational study. CTSI was evaluated using contrast-enhanced CT scans conducted between days three and five, and BISAP scores were computed within twenty-four hours after admission. The two scoring systems' correlation and their relationship to clinical outcomes, including ICU admission, complications, and mortality, were examined using the proper statistical techniques. Results: Our study showed that the mean age of patients was 43.6 years and majority of patients were men, and the most prevalent cause was alcohol-induced pancreatitis. The average length of stay in the hospital was 6.7 days. ICU admissions, death, and severe pancreatitis were all substantially correlated with higher BISAP scores. 20% showed severe CT abnormalities, while the majority of patients had mild to moderate CTSI scores. BISAP and CTSI scores showed a substantial positive connection, suggesting that both scores rise as the severity of the disease increases. Conclusion: We conclude that BISAP score is a better predictor of severity and mortality in acute pancreatitis and can safely be utilized to predict severity of acute pancreatitis in situations where use of CT is limited due to cost factor or availability, especially in rural areas.
