Abstract

IntroductionMany patients presenting with acute gastrointestinal hemorrhage GIH are admitted to the intensive care unit ICU for monitoring. A simple triage protocol based upon validated risk factors could decrease ICU utilization.

MethodsRecords of 188 patients admitted with GIH from the emergency department ED were reviewed for BLEED criteria visualized red blood, systolic blood pressure below 100 mm Hg, elevated prothrombin time PT, erratic mental status, and unstable comorbid disease and complication within the first 24 hours of admission. Variables associated with early complication were reassessed in 132 patients prospectively enrolled as a validation cohort. A triage model was developed using significant predictors.

ResultsWe studied 188 patients in the development set and 132 in the validation set. Red blood relative risk RR 4.53, 95% confidence interval CI 2.04, 10.07 and elevated PT RR 3.27, 95% CI 1.53, 7.01 were significantly associated with complication in the development set. In the validation cohort, the combination of red blood or unstable comorbidity had a sensitivity of 0.73, a specificity of 0.55, a positive predictive value of 0.24, and a negative predictive value of 0.91 for complication within 24 hours. In simulation studies, a triage model using these variables could reduce ICU admissions without increasing the number of complications.

ConclusionPatients presenting to the ED with GIH who have no evidence of ongoing bleeding or unstable comorbidities are at low risk for complication during hospital admission. A triage model based on these variables should be tested prospectively to optimize critical care resource utilization in this common condition.
