Evaluating the prognostic performance of the novel ERAP score in Vietnamese acute pancreatitis patients

Early recognition of severe acute pancreatitis (AP) is crucial for timely intervention. This study aims to evaluate the prognostic accuracy of the Emergency Room Assessment of AP (ERAP) score and compare it with the Bedside Index for Severity in AP (BISAP) score in predicting severe AP, mortality, and persistent multiple organ failure (MOF) in Vietnamese patients. This prospective cohort study included AP patients admitted to Cho Ray Hospital between August 2021 and May 2022. Patient data, including demographics, clinical presentations, and laboratory results, were collected upon admission. The ERAP and BISAP scores were calculated from these admission data. The prognostic accuracy for severe AP, mortality, and persistent MOF was assessed via the area under the receiver-operating characteristic curve (AUC). Among 167 AP patients (mean age 41.5 ± 12.0 years), hypertriglyceridemia (34.7%) and alcohol (22.2%) were the most prevalent etiologies. Severe AP accounted for 33.5% of the patients. Mortality rates were higher in persistent MOF patients (42.9%) than in persistent single-organ failure patients (3.6%), with a P value <.001. The ERAP score had AUCs for predicting severe AP, mortality, and persistent MOF of 0.899, 0.817, and 0.867, respectively, with an optimal cutoff of ≥2. The ERAP score had a better prognostic value than the BISAP score in predicting severe AP (AUC: 0.899 vs 0.820; P = .0072) and persistent MOF (AUC: 0.867 vs 0.785; P = .0193) but had a similar prognostic value for mortality (AUC: 0.817 vs 0.728; P = .0628). The ERAP score has strong predictive value for severe AP and persistent MOF, surpassing the BISAP score in these categories while maintaining similar accuracy for mortality prediction in the Vietnamese population. The ERAP score can be a valuable tool for the early identification of high-risk AP patients, enabling timely and appropriate clinical interventions.
