ARTICLE HIGHLIGHTS
Research background

Upper gastrointestinal bleeding (UGIB) is divided into nonvariceal UGIB (NVUGIB) and variceal UGIB (VUGIB), with rising NVUGIB cases due to an aging population and more non-steroidal anti-inflammatory drugs use, and VUGIB typically resulting from liver cirrhosis with substantial mortality. Despite medical and endoscopic progress, UGIB maintains a high morbidity and mortality rate, with persistent high hospitalization challenges and a 30-day mortality rate of 11% in China, highlighting its critical status as a healthcare emergency.

Research motivation

UGIB prognostic scoring systems are inconsistently applied in clinical practice, with limited impact on decision-making due to variances in primary outcomes and lack of validation. The absence of trial-based evidence for these scores contributes to their uncertain utility in Chinese clinical settings.

Research objectives

The goal of this study is to identify key factors that influence poor UGIB outcomes (e.g., the demand for emergency surgery or vascular intervention, being transferred to the intensive care unit, and dying during hospitalization) and develop a simplified, effective scoring system to guide risk stratification and treatment decisions in Chinese UGIB patients.

Research methods

A retrospective study used UGIB patient data from East Hospital as a training cohort and from Changzheng Hospital as a validation cohort to construct and test a new scoring model based on major predictors of UGIB outcomes, including endoscopic findings. A nomogram derived from this model was developed, validated, and compared to existing UGIB scores, with an alternative pre-endoscopic model also assessed. The study employed extensive clinical data and statistical analyses, like multivariate analysis and receiver operating characteristic (ROC) curves, to evaluate the models' effectiveness, focusing on the composite endpoint of emergency surgery, vascular intervention, ICU transfer, or in-hospital mortality.

Research results

Univariate analysis determined factors related to negative outcomes in UGIB, leading to the creation of the MH-STRALP scoring system, which incorporates seven prognostically significant factors plus the risk of rebleeding. The MH-STRALP system showed better prognostic accuracy compared to other established scoring systems (GBS, Rockall, ABC, AIMS65, and PNED), with areas under ROC curves (AUROC) of 0.899 and 0.826 in the training and validation cohorts, whilst the pre-MH-STRALP score also showed better predictive value (AUROCs of 0.868 and 0.767 in the training and validation cohorts, respectively).These two scoring systems are helpful in prognosticating Chinese UGIB patients, providing personalized appropriate treatment and management, and facilitating early clinical decision-making.

Research conclusions

With this study, we constructed new scoring systems, MH-STRALP and pre-MH-STRALP, to predict the prognosis of patients with UGIB, with compound endpoint events of undergoing emergency surgery or vascular intervention, being transferred to the ICU, or dying during hospitalization; we formulated a nomogram to present the scoring system.

Research perspectives

Since this is a retrospective study and we did not make prognostic predictions for patients with UGIB who did not undergo endoscopy, there may be bias. Further large-scale prospective studies are necessary to verify the value of the scoring systems.
