Description of intervention(s) / exposure
A prospective validation study of the Glasgow-Blatchford Score

The Gastroenterology and Emergency Department (ED) will be informed of the proposed research project, in the form of an oral presentation by the Principal Investigators. Both departments will identify patients presenting with upper gastrointestinal bleeding in ED. In order to facilitate their decision making, potential participants will be given a patient information sheet and consent form. Flyers have been placed around ED for awareness of the study in the department. Patients who meet the inclusion criteria, either in the Emergency Department or on the wards, will be invited to participate in the study via telephone. After being consented with the consent form, those patients with a Glasgow-Blatchford Score (GBS) of three or less will be discharged, and an outpatient endoscopy within 2 weeks will be performed. If patients have a GBS of greater than 3, they will be admitted to the Royal Adelaide Hospital and an endoscopy will be performed at the hospital within 24 hours. In both cases, if therapeutic intervention is required, this treatment will also be carried out. Patients will also receive one long term follow up phone call.

Eligibility
Key inclusion criteria
Two groups of hospitalised patients, aged greater than or equal to 18 years, who present to, or at, the Royal Adelaide Hospital for the management of UGIH. The first group of patients will be those presenting to the ED with a primary diagnosis of UGIH. The second group of patients will be inpatients who develop an UGIH during their admission at the Royal Adelaide Hospital. UGIH is defined as bleeding from the upper gastrointestinal tract as manifested by haematemesis (including coffee-ground vomiting) and/or melaena. Both variceal and non-variceal causes of UGIH will be included in the study.
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1) Patients who are unable to give informed consent, and without the presence of a next of kin upon admission.
2) Patients with urgent medical comorbidities, other than UGIH, which require inpatient admission.
3) A known pre-existing cause of UGIH.
4) Patients in whom outpatient follow-up cannot be guaranteed, including:
a) Persons of no fixed address
