Critical peptic ulcer bleeding requiring massive blood transfusion: outcomes of 270 cases

Critical peptic ulcer bleeding requiring massive transfusion is a gastroenterological emergency. Few data exist on management and outcomes. The Australian and New Zealand Massive Transfusion Registry collects comprehensive data on adult patients receiving massive transfusion across all bleeding contexts.

To evaluate clinical factors, management (procedural interventions, transfusions) and outcomes after massive transfusion for critical peptic ulcer bleeding.

Demographics, diagnosis, procedures and mortality data were available for 5482 massive transfusion cases from 23 hospitals. International Classification of Diseases 10th Edition, Australian Modification codes were used to determine peptic ulcer bleeding and the Australian Classification of Health Intervention for interventions (i.e. endoscopic, radiological, surgical).

Peptic ulcer bleeding accounted for 270 (4.9%) of all in-hospital massive transfusion cases; 70% were male. Median number of red blood cell (RBC) units transfused was 7 (interquartile range, 6-10). Thirty-day mortality was 19.6%. Age (75 vs 67 years; P = 0.009) and Charlson Comorbidity Index (3 vs 1; P < 0.001) were higher in those who died. Highest 24-h international normalised ratio (1.5 vs 1.4; P < 0.001) and creatinine (118 μmol/L vs 96 μmol/L; P = 0.03) and nadir platelet count (86 × 10⁹ /L vs 118 × 10⁹ /L; P = 0.01) were also associated with 30-day mortality. There were no differences in mortality according to number of RBC, platelets or plasma units transfused, gastroscopy (with or without intervention), interventional radiology or surgery.

One in five patients with critical peptic ulcer bleeding requiring massive transfusion died by 30 days. Mortality was associated with patient characteristics rather than clinical interventions (e.g. procedures, blood product transfusion).
