Validation of a clinical prediction rule for severe acute lower intestinal bleeding.
Acute lower intestinal bleeding is a heterogeneous disorder and identification of high-risk patients is challenging. We previously retrospectively identified predictors of severity in patients with acute lower intestinal bleeding. The aim of this study was to prospectively validate a clinical prediction rule for severe acute lower intestinal bleeding. ⋯ We have developed and prospectively validated a clinical prediction rule for acute severe lower intestinal bleeding. This prediction rule could improve the triage of patients to appropriate levels of care and interventions, and guide a more standardized approach to acute lower intestinal bleeding.
