Abstract
Abstract Aims This audit aimed to assess the necessity of routine preoperative blood grouping and saving (G&S) tests for patients undergoing laparoscopic appendicectomy. Specifically, we evaluated the frequency of perioperative blood transfusions and conducted a cost analysis of G&S samples. The secondary aim was to determine if routine G&S testing could be optimized to reduce unnecessary resource use. Methods The audit was conducted in two cycles: the first (October–December 2024) included 150 patients, and the second (January–May 2025) included 100 patients. Retrospective analysis of case notes was performed, collecting data on demographics, ASA (American Society of Anesthesiologists) grades, number of G&S samples, and blood transfusion requirements. Inclusion criteria were laparoscopic appendicectomy patients, excluding high-risk individuals, those on anticoagulants, or with preoperative anemia. Results In the first cycle, no patients required blood transfusions. Of 150 patients, 75% had two G&S samples, and 21% had one. A similar pattern was observed in the second cycle, with no transfusions required. Demographics, including ASA grades, were consistent across both cycles, with 53% of patients being ASA Grade 1 in cycle one and 80% in cycle two. Conclusions Routine preoperative G&S testing for laparoscopic appendicectomy is unnecessary, as no transfusions were required in either cycle. We recommend a more selective approach to G&S testing, based on patient risk factors such as comorbidities, anticoagulant use, and anemia, improving cost-efficiency without compromising safety.
