Strengths and limitations of risk stratification tools for patients with upper gastrointestinal bleeding: a narrative review.

The current evidence supports using the Glasgow Blatchford Score as it is the most accurate tool available when attempting to identify low risk patients who can be safely managed on an outpatient basis. Currently, no risk assessment tool appears accurate enough in confidently classifying patients as high risk. Future research should utilize more standardized methodologies, while favoring interventional trial designs to better characterize the clinical impact attributable to the use of such risk stratification schemes.
