Evaluating the effectiveness of BISAP score in predicting severity of acute pancreatitis.

Objective: To assess the efficacy of the BISAP score in predicting the severity of acute pancreatitis. Study Design: Cross Sectional, Retrospective. Setting: Surgical Unit, Mardan Medical Complex, KPK. Period: June 2022 to October 2024. Methods: A sample size of 192 was determined. The study included patients aged 18-60 years, of both genders, diagnosed with acute pancreatitis based on the American Pancreatic Association criteria. Data was collected using a standardized form and analyzed with SPSS version 22. Results: Among the 192 patients, males and females’ ratio was 1.4: 1. with mean age of 35.89 ± 13.39 years. 31.2% had severe acute pancreatitis (score >3), while 68.75% had mild pancreatitis (p value < 0.001). The area under curve was 0.98, indicating strong diagnostic power. The study had a sensitivity 96.67%, specificity 93.2%, positive likelihood ratio (PPV) 86.6%, and true negative rate (NPV) of 98.43%. Overall diagnostic effectiveness for severity and mortality was 94.3% and 80.7%, respectively. Conclusion: The BISAP score is reliable, rapid, and cost-effective means for assessing severity, enabling effective patient stratification and prompt initiation of intensive management of severe patients to reduce mortality and morbidity.
