Mid-gastrointestinal bleeding accounts for approximately 5%-10% of all gastrointestinal bleeding cases, and vascular lesions represent the most frequent cause. The rebleeding rate for these lesions is quite high (about 42%). We hereby recommend that scheduled outpatient management of these patients could reduce the risk of rebleeding episodes.

BACKGROUND: The Glasgow-Blatchford scale (GBS) classifies the risk of re-bleeding after upper gastrointestinal bleeding (UGIB) using clinical data, whereas the Forrest and Dagradi scales do it by endoscopy.
OBJECTIVE: To assess GBS\'s ability to identify re-bleeding risk within 30 days of an UGIB, using endoscopy as the gold standard for comparison.
METHODS: 129 medical records of patients with UGIB and endoscopy were analyzed. The Glasgow-Blatchford, Forrest and Dagradi scales were quantified; sensitivity, specificity and area under the ROC curve (AUC-ROC) of GBS-reported re-bleeding risk were calculated.
RESULTS: GBS identified 53 patients with low re-bleeding risk (41.09 %) and 76 with high risk (58.91 %). Endoscopy identified 107 patients with non-variceal bleeding (82.94 %): 98 with low risk (89.9 %) and 11 with high risk (10.09 %); in addition, it identified 22 patients with variceal hemorrhage (17.05 %): 12 with low risk (54.54 %) and 10 with high risk (45.45 %). GBS showed a sensitivity of 0.857, specificity of 0.462 and an AUC-ROC of 0.660.
CONCLUSIONS: GBS is simple, objective and useful to identify the risk of re-bleeding after UGIB; it is suggested as a triage tool in the emergency department.
UNASSIGNED: Con la escala de Glasgow-Blatchford (EG-B) se califica mediante datos clínicos, el riesgo de resangrado después de hemorragia del tubo digestivo alto (HTDA); y con las escalas de Forrest y Dagradi, mediante endoscopia.
UNASSIGNED: Evaluar la capacidad de la EG-B para identificar riesgo de resangrado a 30 días después de una HTDA; el estándar de oro de comparación fue la endoscopia.
UNASSIGNED: Se analizaron 129 expedientes de pacientes con HTDA y endoscopia. Se cuantificaron las escalas de Glasgow-Blatchford, Forrest y Dagradi; se calculó sensibilidad, especificidad y área bajo la curva ROC (ABC-ROC) del riesgo de resangrado reportado por EG-B.
UNASSIGNED: La EG-B identificó a 53 pacientes con riesgo bajo de resangrado (41.09 %) y 76 con riesgo alto (58.91 %). Con la endoscopia se identificó a 107 pacientes con hemorragia no variceal (82.94 %), 98 con riesgo bajo (89.9 %) y 11 con riesgo alto (10.09 %); además, 22 pacientes con hemorragia variceal (17.05 %), 12 con riesgo bajo (54.54 %) y 10 con riesgo alto (45.45 %). La EG-B mostró sensibilidad de 0.857, especificidad de 0.462 y ABC-ROC de 0.660.
UNASSIGNED: La EG-B es sencilla, objetiva y útil para identificar riesgo de resangrado después de HTDA; se sugiere como herramienta de triaje en urgencias.
