en Assessment of ABC Score as a Predictor of Hospital Outcomes in Gastrointestinal Bleeding Patients Clinical Medicine Clinical Medicine مقاله پژوهشی Original Research Article Background and Objective: To evaluate ABC score as a predictor of hospital outcomes in gastrointestinal bleeding patients. Materials and Methods: In this cross-sectional study, 171 patients with GI bleeding patients referred to Vali-Asr Hospital of Zanjan were investigated during 2023. Demographic and clinical variables, extracted from patients’ medical records. Statistical analyses were performed using Stata 14. ROC curve was applied to determine the optimal cutoff value of the ABC score for predicting in-hospital mortality, length of stay, and duration of mechanical ventilation. Results: The mean age of patients was 56.50 ± 19.70 years (range: 15–97), with 68% males. The mean ABC score was 3.12 ± 3.12 (range: 0–13). The most common endoscopic findings were non-active bleeding gastric ulcer (15.1%), erosive gastropathy (13.4%), and non-active bleeding duodenal ulcer (11.6%). Hematemesis (46.5%), melena (28%), and rectorrhagia (17.4%) were the most frequent clinical presentations. The optimal cutoff value of the ABC score for predicting in-hospital mortality was 6, with sensitivity of 92.3%, specificity of 83.5%, PPV of 84.9%, NPV of 90.6%, and an AUC of 0.92. A cutoff of 6 also best predicted mechanical ventilation duration (sensitivity: 91.7%, specificity: 81.0%, AUC: 0.91). For length of hospital stay, the optimal cutoff was 5 (sensitivity: 84.2%, specificity: 80.3%, AUC: 0.88). Conclusion: ABC score has strong predictive accuracy for in-hospital mortality, hospital stay, and mechanical ventilation among patients with GI bleeding. Given its simplicity and reliability, the ABC score may serve as a practical tool in clinical decision-making for this high-risk population.   ABC score, diagnostic value, mortality, gastrointestinal bleeding 43 43 http://journal.zums.ac.ir/browse.php?a_code=A-10-7192-2&slc_lang=en&sid=1 Kamyar Mansori kamyarmansori@yahoo.com 5200319475328460090362 5200319475328460090362 No Zanjan University of Medical Sciences Sattar Jafari Jafari215@yahoo.com 5200319475328460090363 5200319475328460090363 No Zanjan University of Medical Sciences Salar Hejabari Safa Salar_Hejabari@gmail.com 5200319475328460090364 5200319475328460090364 No Zanjan University of Medical Sciences Mahdieh Sheikhi Mahdieh_sh@gmail.com 5200319475328460090365 5200319475328460090365 No Zanjan University of Medical Sciences Giti Karimkhanlooei gitikarimkhanlooei@gmail.com 5200319475328460090366 5200319475328460090366 No Zanjan University of Medical Sciences Mohsen Salehi mohsen_salehi44@yahoo.com 5200319475328460090367 5200319475328460090367 Yes Zanjan University of Medical Sciences
