GI bleeding is not about bleeding for hospitalist. You must be familiar with Forrest class (Table 35.6) based on EGD to determine PPI intensity and diet (Tables 35.7 and 35.8). Rebleeding risk and mortality is based on Rockall score (Table 35.1), in-hospital mortality is based on AIMS65 (Table 35.2). Glasgow-Blatchford score is useful if patients should be admitted or not (Table 35.3), PEND score (Table 35.4) is for overall 30-day mortality. The most important question of all for hospitalist is to determine when we can resume anticoagulation and/or antiplatelet after the bleeding (Tables 35.9 and 35.10).
