IntroductionThis study aimed to identify the blood transfusion rates for several surgical procedures in a single district general hospital and assess the value of preoperative blood type and antibody screen across all relevant surgical procedures. We hypothesized that there was an overuse of blood type and antibody screen in our general surgical population.MethodsA database containing transfusions of patients who underwent elective- or emergency surgery from January 2015 to September 2020 was matched to a database of preoperative type-and-screen performed in the same period. Registered procedures where the incidence of transfusion is deemed low were excluded. The included procedures were assessed for the intraoperative usefulness of type- and-screen testing.ResultsIn the included 68.892 surgeries, 36.134 (52.0%) blood samples were preoperatively tested for the blood type and screened for antibodies according to the hospital's routine. Overall 3.517 (5.1%) of surgeries had patients that received a transfusion in the perioperative period and 1.2% (n = 850) during the surgery.ConclusionMost surgeries had a very low incidence of transfusion. Despite this, type-and-screen tests were widely used. This suggests the need for a more focused pre-surgery type-and-screen approach, and a more data driven approach to local guidelines in collaboration with surgical specialties.© 2024 The Author(s).
