External Validation of SHA2PE Score: A Score to Predict Low-Risk Lower Gastrointestinal Bleeding in the Emergency Department

Conclusions: The SHA2PE score demonstrates potential in predicting cases of low-risk LGIB, offering a high NPV for hospitalization, the need for intrahospital intervention, and return visits to the ED. However, these findings should be interpreted cautiously given the low prevalence of interventions and limitations in the study’s population and design.
