Comparison of The Accuracy of The Blunt Abdominal Trauma Scoring System and The Novel Scoring System in Predicting Outcomes in Patients With Blunt Abdominal Trauma At Dr. Soetomo General Hospital, Surabaya, January–December 2025

Abstract

Background: Blunt abdominal trauma is a significant cause of morbidity and mortality among trauma patients. Rapid determination of the need for laparotomy is essential to prevent delays in treatment. Several scoring systems, including the Blunt Abdominal Trauma Scoring System (BATSS) and the Novel Scoring System, have been developed to assist in predicting the need for operative intervention. This study aimed to compare the accuracy of these two scoring systems in predicting the need for laparotomy in patients with blunt abdominal trauma.

Objective: This observational analytic study employed a retrospective cohort design using medical records of 82 patients with blunt abdominal trauma treated at Dr. Soetomo General Hospital, Surabaya, from January to December 2025. The diagnostic performance of BATSS and the Novel Scoring System was evaluated using receiver operating characteristic (ROC) curve analysis, including area under the curve (AUC), sensitivity, specificity, and accuracy.

Results: The AUC of BATSS was 81%, which was higher than that of the Novel Scoring System (73.2%). At a cut-off value of 10.5, BATSS demonstrated a sensitivity of 60%, specificity of 97.3%, and accuracy of 81%. In comparison, the Novel Scoring System at a cut-off value of 0.75 demonstrated a sensitivity of 57.8%, specificity of 89.2%, and accuracy of 73.2%. These findings indicate that BATSS is superior in identifying patients who require and those who do not require laparotomy.

Conclusion: BATSS demonstrated better diagnostic performance than the Novel Scoring System in predicting the need for laparotomy in patients with blunt abdominal trauma and may serve as an adjunctive tool for initial screening and clinical decision-making.
