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.
