The Progetto Nazionale Emorragia Digestiva (PNED) system vs. the Rockall score as mortality predictors in patients with nonvariceal upper gastrointestinal bleeding: A multicenter prospective study.

Background: The predictive scale for mortality risk in patients with nonvariceal upper gastrointestinal bleeding (NVUGIB) proposed by Italy's PNED (Progetto Nazionale Emorragia Digestiva) group has not been validated in Latin America since its original publication.

Aim: To compare the PNED system and the Rockall score as mortality predictors in patients hospitalized for NVUGIB.

Material And Methods: A multicenter, prospective, cross-sectional, analytic study was conducted that recruited patients diagnosed with nonvariceal upper gastrointestinal bleeding within the time frame of 2011 to 2015.
