The objective of this study was to design and implement a maximum surgical blood order schedule (MSBOS) within a specialist gynecological oncology department in a tertiary referral center and evaluate its impact on the cross-match to transfusion ratio (CTR). A retrospective case note audit was undertaken to identify common operations performed within the unit and their transfusion requirements. The efficiency of blood usage was assessed using the CTR, and an MSBOS was devised and implemented. A prospective audit of preoperative blood cross-matching and subsequent blood usage was then performed for consecutive elective operations in the unit, to assess the effect of the MSBOS. The retrospective study of 222 cases demonstrated a CTR of 2.25 equivalent to 44% usage of cross-matched blood. Ninety two percent of operations performed within the unit could be incorporated into an MSBOS. The prospective study of 207 cases demonstrated a significantly reduced CTR of 1.71 or 59% blood usage (χ2 = 12.4, P < 0.001). This equates to a saving of 102 units of blood over the 15 months prospective audit. Protocol adherence was 77%. No patient was adversely affected by the adoption of the MSBOS. We conclude that an MSBOS can be safely introduced into a gynecological oncology department resulting in significant financial savings.
