External Validation of the Glasgow-Blatchford Bleeding Score in a Tunisian Population

This study aims to externally validate the Glasgow-Blatchford Score (GBS) in a Tunisian population presenting with non-traumatic upper gastrointestinal bleeding. Despite advances in endoscopic management, early risk stratification remains essential to guide clinical decision-making. In Tunisia, the routine hospitalization of all patients for observation presents a challenge, highlighting the need for reliable prognostic tools. The study is designed as a multicenter, descriptive, and analytical investigation across several emergency departments. Adult patients (≥16 years) will be included, with follow-up conducted at 30 days to assess for adverse outcomes including rebleeding, the need for hemostasis, complications, and mortality. Clinical and epidemiological data will be collected using a standardized form. Statistical analysis will evaluate the predictive performance of the GBS, focusing on sensitivity, specificity, and predictive values for 30-day outcomes. The results are expected to determine whether GBS is a valid and useful tool for risk assessment in the Tunisian context, potentially aiding in more efficient and targeted patient management.
