RT Journal Article SR Electronic T1 The influence of a simple blood transfusion policy on overtransfusion in acute upper gastrointestinal haemorrhage  JF Clinical Medicine JO Clin Med FD Royal College of Physicians SP 325 OP 329 DO 10.7861/clinmedicine.15-4-325 VO 15 IS 4 A1 Adam Stokes A1 Clare Thompson A1 Andrew Clegg A1 Jonathon Snook YR 2015 UL http://www.rcpjournals.org/content/15/4/325.abstract AB Blood transfusion is widely used in the management of acute upper gastrointestinal haemorrhage (AUGIH). Trial data suggests that excessive transfusion may be detrimental, yet overtransfusion remains commonplace. This study reports the impact of introducing a simple cross-match policy in a district general hospital, which resulted in a substantial fall in the prevalence of overtransfusion (odds ratio 0.43; 95% confidence interval 0.19–0.98), with potential patient benefits in terms of rebleeding, and a reduction in the total blood transfused from 162 to 121 units per 100 patients with AUGIH. For the cost of blood alone, this corresponds to projected savings across the NHS in England in excess of £2 million per annum.
