Several clinical risk scores are available, but their comparative performance across outcomes and patient subgroups remains uncertain. We compared five established UGIB risk scores for predicting inpatient mortality and complications in a large United Kingdom (UK) cohort and evaluated performance according to bleeding aetiology and sex. We also explored the incremental prognostic value of body mass index (BMI). Methods: We conducted a retrospective cohort study of 1003 hospitalised patients with UGIB who underwent oesophagogastroduodenoscopy at a UK tertiary centre (2023\u20132025). Five risk scores were evaluated: age, blood tests, and comorbidities (ABC); mental status\u2013anaesthesiologist score\u2013pulse\u2013albumin\u2013systolic blood pressure\u2013haemoglobin (MAP(ASH)), Charlson comorbidity index\u2013hospital-onset\u2013albumin\u2013mental status\u2013Eastern Cooperative Oncology Group performance status\u2013steroids (CHAMPS), Glasgow\u2013Blatchford score (GBS), and the Japanese score. The primary outcome was inpatient mortality, and the secondary outcome was an inpatient complication composite comprising rebleeding, repeat endoscopy, or interventional radiology. Discrimination was assessed using area under the receiver operating characteristic curves (AUROCs), with pairwise comparisons using the DeLong test. BMI was evaluated using multivariable regression and AUROC analysis. Results: ABC demonstrated the highest numerical discrimination for inpatient mortality (AUROC 0.817), followed by CHAMPS (0.791) and MAP(ASH) (0.774), with no statistically significant differences between these three scores. For inpatient complications, MAP(ASH) had the highest numerical AUROC (0.697), although its performance did not differ significantly from CHAMPS, GBS, or ABC. Exploratory subgroup analyses demonstrated generally good mortality discrimination for ABC and CHAMPS across bleeding aetiology and sex. Adding BMI to ABC increased the AUROC from 0.817 to 0.828, although this was not statistically significant (p = 0.224). Conclusions: ABC, CHAMPS, and MAP(ASH) demonstrated the strongest discrimination for inpatient mortality, while discrimination for inpatient complications was more modest across scores. These findings do not establish the clinical superiority of a single scoring system, and BMI did not provide significant incremental prognostic value.<\/jats:p>","DOI":"10.3390\/jcm15197503","type":"journal-article","created":{"date-parts":[[2026,9,28]],"date-time":"2026-09-28T16:50:54Z","timestamp":1790614254000},"page":"7503","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Validation and Performance of Five Upper Gastrointestinal Bleeding Prognostication Scores in a Single-Centre United Kingdom Cohort of over 1000 Patients"],"prefix":"10.3390","volume":"15","author":[{"given":"Mohamed","family":"Jalloh","sequence":"first","affiliation":[{"name":"Department of Gastroenterology, Royal Stoke University Hospital, University Hospitals of North Midlands NHS Trust, Stoke-on-Trent ST4 6QG, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2315-0744","authenticated-orcid":false,"given":"Balamrit Singh","family":"Sokhal","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Royal Stoke University Hospital, University Hospitals of North Midlands NHS Trust, Stoke-on-Trent ST4 6QG, UK"},{"name":"School of Medicine, Keele University, Keele ST5 5BG, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maryam Nusrat","family":"Javed","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Royal Stoke University Hospital, University Hospitals of North Midlands NHS Trust, Stoke-on-Trent ST4 6QG, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Humberto","family":"Gomez","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Royal Stoke University Hospital, University Hospitals of North Midlands NHS Trust, Stoke-on-Trent ST4 6QG, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jessica","family":"Lightfoot","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Royal Stoke University Hospital, University Hospitals of North Midlands NHS Trust, Stoke-on-Trent ST4 6QG, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hareesha Rishab","family":"Bharadwaj","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Royal Stoke University Hospital, University Hospitals of North Midlands NHS Trust, Stoke-on-Trent ST4 6QG, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1794-2569","authenticated-orcid":false,"given":"Arkadeep","family":"Dhali","sequence":"additional","affiliation":[{"name":"Academic Unit of Gastroenterology, Sheffield Teaching Hospitals NHS Foundation Trust, Sheffield S5 7AU, UK"},{"name":"School of medicine, Dentistry and Biomedical Sciences, Queen\u2019s University Belfast, Belfast BT9 7BL, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5050-9599","authenticated-orcid":false,"given":"Farhan","family":"Gohar","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Royal Stoke University Hospital, University Hospitals of North Midlands NHS Trust, Stoke-on-Trent ST4 6QG, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1215","DOI":"10.1016\/j.gie.2011.06.024","article-title":"A simple risk score accurately predicts in-hospital mortality, length of stay, and cost in acute upper GI bleeding","volume":"74","author":"Saltzman","year":"2011","journal-title":"Gastrointest.
