Plain English summary of protocol

Background and study aims
Upper gastrointestinal bleeding refers to bleeding in the esophagus (foodpipe), stomach or duodenum (first section of the small intestine). Recent guidelines have recommended the use of early risk assessment in patients with upper gastrointestinal bleeding. A number of risk scores have been developed for use in this situation, some of which can be calculated soon after admission to hospital and some of which require endoscopy for calculation. Endoscopy involves a flexible tube with an attached light and camera being passed through the mouth and throat, allowing the doctor to view the esophagus, stomach and duodenum. There have been several studies comparing various combinations of risk scores for upper gastrointestinal bleeding, but we do not know which is the best score for use in clinical practice. The aim of this study is to compare the usefulness of five risk scores in patients with upper gastrointestinal bleeding.

Who can participate?
Patients with upper gastrointestinal bleeding.

What does the study involve?
We collect data including patients’ characteristics, blood test results, findings at endoscopy (if undertaken), and any treatments such as blood transfusion, endoscopic treatment and surgery. Bleeding, length of hospital stay and number of deaths are also recorded. The data is then used to compare the predictive abilities of the different risk scores.

What are the possible benefits and risks of participating?
The results of this study will be used to develop a new improved score to improve the prediction of outcome for patients with upper gastrointestinal bleeding. All patient management will be as per standard of care for patients with upper gastrointestinal bleeding. All collected data will be anonymized.

Study typeDiagnostic
Scientific titleInternational multicentre prospective study to compare risk scoring system for patients presenting with upper gastrointestinal bleeding
Study objectivesTo compare the ability of five existing risk scoring systems (the Full and Clinical Rockall scores, the Italian PNED score, the Glasgow Blatchford (GBS) and the American AIM65 score) to predict outcomes in upper gastrointestinal bleeding (UGIB):
1. Need for hospital-based intervention or mortality
2. Rebleeding within 7 days
3. Length of hospital stay
4. 30-day mortality.

Health condition(s) or problem(s) studiedUpper gastrointestinal bleeding (UGIB)
InterventionThis is an international observational study across seven international sites, to compare five established risk assessment scores in the prediction of clinical outcomes for patients presenting with UGIB. We will collect data to calculate these scores for each patient, then compare the scores' ability to predict the pre-determined end-points.

There are no interventions. We will simply collate data on presentation to hospital with UGIB to allow measurement of the recognised risk scoring systems for this condition. We will then follow up the patients to determine outcomes as described above in the study hypothesis section.
Intervention typeOther
Primary outcome measureNeed for hospital-based intervention or 30-day mortality on follow-up
Secondary outcome measures1. Rebleeding within 7 days
2. Length of hospital stay
