Predicting in-hospital mortality in patients with acute pancreatitis in the ED: a direct, retrospective comparison of four clinical and radiological prognostic scores

BACKGROUND: Acute pancreatitis can be a severe disease that significantly impacts patients' quality of life and outcome. The clinical course is variable and predictive scoring systems have a debated role in early prognosis. This study aims to compare the prognostic accuracy of Balthazar, BISAP, HAPS and SOFA scores in the prediction of in-hospital mortality in patients with acute pancreatitis. METHODS: December 2021 for the first episode of acute pancreatitis were included. RESULTS: A total of 385 patients (mean age of 65.4 years and 1.8% in-hospital mortality) were studied. Balthazar, BISAP and SOFA scores were significantly higher in patients with in-hospital mortality and AUROCs were equal to 0.95 (95% CI 0.91-0.99, P<0.001), 0.96 (95% CI 0.89-1, P=0.001), 0.91 (95% CI 0.81-1, P=0.001) with no differences among them and absence of in-hospital mortality in patients with HAPS=0. CONCLUSIONS: Our data support the concept that clinical prediction scores can be useful for risk stratification in the Emergency Department. However, no single score has shown superiority in predicting acute pancreatitis-related in-hospital mortality among tested tools.
