Supplement:
The mortality rate in cases of upper gastrointestinal bleeding (UGIB) is 10-14%, and guidelines recommend that patients with UGIB undergo an endoscopy within 24 hours of hospital admission.1-3 However, performing an emergent endoscopy for all UGIB patients is difficult. Although the Glasgow Blatchford Score (GBS) assesses the risk of UGIB before endoscopy, it is not suitable for predicting an emergent endoscopy because it was developed to predict composite outcomes (blood transfusion, endoscopic treatment, surgery, or death). 4 We therefore developed the Simple Emergent Endoscopy (SEE) score to determine if patients with suspected UGIB should undergo an emergent endoscopy. SEE assesses both variceal and non-variceal bleeding, an important point given that the source of the hemorrhage is unknown when the decision to perform an emergent endoscopy is made.

SEE score consists of three variables, namely, “no daily use of proton pump inhibitor during one week before examination (+1),” “shock index (heat rate/systolic blood pressure) ≥1 (+1),” and “Urea/Creatinine≥140 (Blood urea nitrogen/Creatinine ≥30) (+1)”. (Figure 1) The range is 0 to 3 points, making the SEE score much simpler to use than the GBS, which contains eight complicated variables and a range of 0 to 23 points.4 Despite its simplicity, the SEE score has significantly greater accuracy (AUC: 0.74) for predicting the need for an endoscopic intervention than the GBS (AUC: 0.63) (p<0.001). Moreover, the continuous net reclassification improvement (NRI) was 0.57 (p<0.001) and the integrated discrimination improvement (IDI) was 0.15 (p<0.001). Furthermore, the SEE score (AUC: 0.76) performs just as well as the full Rockall score (AUC: 0.76) (p=0.65).

Table 1 shows the SEE score and the outcomes including additional data (from 2008 to 2016). These results show that an emergent endoscopy is required when the SEE score is 2 or 3 while patients with a score of zero could be managed as outpatients as they are less likely to have high-risk stigmata. The SEE score is easy and clinically useful in the management suspected UGIB.
