Introduction:

Several scoring systems exist to predict adverse outcomes in patients with nonvariceal upper gastrointestinal bleeding, but they have not been sufficiently validated and each pertains to different source populations.

Objective:

To demonstrate the usefulness of a proposed scoring scale to predict the probability of rebleeding, mortality, and need for surgery in patients with nonvariceal upper gastrointestinal bleeding.

Methods:

A retrospective study of a diagnostic test was performed at the hospital of Prenda, Luanda, Angola, from January 2021 to May 2022. The study universe consisted of 93 patients attended during that period, with the inclusion criterion of having a diagnosis of upper gastrointestinal bleeding of nonvariceal origin.

Results:

From a total of 93 patients, the primary outcome was a recurrence of bleeding in 18 patients, accounting for 19.35% of the total; followed by 12 deaths, representing 12.90% of the total, and four deaths, accounting for 4.40% of the total. After the scale was applied, the following general predictive values were obtained: sensitivity of 0.91, specificity of 0.92, negative predictive value of 0.95 and negative predictive value of 0.86.

Conclusions:

The proposed scale presents adequate sensitivity and specificity for predicting the probability of fatal rebleeding and the need for surgery in patients with nonvariceal upper gastrointestinal bleeding.
