Key Points

To assess the predictive performance of the ABC score for 30-day mortality in gastrointestinal bleeding victims in Tanzania.
Conducted a single-center retrospective cohort study at Muhimbili National Hospital
Evaluated the predictive validity of the ABC score
Identified population-specific cutoff points for improved accuracy
Confirmed good predictive performance of the ABC score in Tanzanian patients
Highlighted the need for calibration of cutoff values for the local population

Abstract

Our study provides the first African validation of the ABC score, confirming a good predictive performance in Tanzanian patients while identifying the need for population-specific cutoff calibration. The ABC score represents a valuable risk stratification tool for both upper and lower gastrointestinal bleeding in resource-limited settings.
