This study investigated the value of the revised Atlanta classification (RAC) and the determinant-based classification (DBC) systems in stratifying severity of acute pancreatitis. Methods: This retrospective observational cohort study included 480 AP patients. Patient demographics and clinical characteristics were recorded. The primary outcome was mortality, and secondary outcomes were admission to intensive care unit (ICU), duration of ICU stay, and duration of hospital stay. Results: Based on the RAC classification, there were 295 patients with mild AP (MAP), 146 patients with moderate-to-severe AP (MSAP), and 39 patients with severe AP (SAP). Based on the DBC classification, there were 389 patients with MAP, 41 patients with MSAP, 32 patients with SAP, and 18 patients with critical AP (CAP). ROC curve analysis showed that the DBC system had a significantly higher accuracy at predicting organ failure compared to the RAC system (pā€‰<ā€‰.001). Multivariate regression analysis showed that age and ICU stay were independent risk factors of mortality. Conclusion: The DBC system had a higher accuracy at predicting organ failure. Age and ICU stay were significantly associated with risk of death in AP patients. A classification of CAP by the DBC system should warrant close attention, and rapid implementation of effective measures to reduce mortality. ER -
