METHODS: We performed a retrospective chart review of 709 patients diagnosed with acute gastrointestinal bleeding between 2009 and 2013. Of these patients, 475 were upper GI bleeds and the balance were lower GI bleeds (164). We excluded any patients not primarily admitted for an acute GI bleeds. As such, ninety-three patients were excluded for being admitted for other primary medical conditions such as pneumonia, sepsis, etc. Additionally, we excluded all patients that malignancies in their medical history, either current or past (106 patients). After exclusions, our evaluable patients numbered 510. The Glasgow Blatchford Bleeding score was then calculated using admission BUN, Hemoglobin, initial SBP, heart rate, Hx of melena, syncope, history of liver disease or heart failure. We ran regression analysis, ANOVA and correlations for each criterion.
