Abstract
Objective: To evaluate the prognostic value of the ABC score in predicting 30-day rebleeding and mortality of patients with peptic ulcer bleeding and to compare its prognostic value with Rockall score. Subject and method: This was a descriptive, prospective study conducted on 211 patients with peptic ulcer bleeding who were treated at 108 Military Central Hospital and Bach Mai Hospital, from October 2022 to July 2023. Receiver Operating Characteristic (ROC) curves were utilized to calculate the prognostic value of the ABC score and compare it with the Rockall score. Result: The study analyzed 211 patients with peptic ulcer bleeding. The ABC score had a good prognostic value for 30-day mortality, with an area under the receiver operating characteristic curve (AUROC) of 0.873, 95%CI: 0.79-0.96; p<0.001. At a cut-off value of 6, it demonstrated a sensitivity of 90.9% and specificity of 76.5%. It also showed an acceptable prognostic value for 30-day rebleeding, with an AUROC of 0.755, 95%CI: 0.63-0.88, p = 0.002. At a cut-off value of 5, it exhibited a sensitivity of 76.9% and specificity of 66.2%. When comparing the ABC score with Rockall score in predicting 30-day rebleeding and mortality, the ABC score had higher AUROC values by 0.112 and 0.06, respectively. However, these differences did not reach statistical significance. Conclusion: The ABC score proves to be a valuable prognostic tool for predicting the risk of 30-day rebleeding and mortality in patients with peptic ulcer bleeding.
