External Validation of the Strate's Predictive Model of Severity in Lower Intestinal Bleeding

Abstract

Introduction: Acute lower intestinal bleeding (LIB) is a common medical emergency. Recently Strate et al. developed and validated a predictive model to assess the severity of acute LIB. Generalisability of a prediction rule in clinical practice requires an external validation in other clinical contexts. Objective: External validation of the Strate severity index for LIB. Patients and Methods: Design: Prospective, cohort study. Patients (validation cohort): Patients admitted to our hospital with the diagnosis of LIB from April 2005 to April 2007.
