Saving Blood and Reducing Costs: Updating Blood Transfusion Practice in Lower Limb Arthroplasty.

Aim Our aim was to quantify blood transfusion rates in lower limb arthroplasty following the introduction of a multimodal enhanced recovery programme (ERP). We then sought to update the maximum surgical blood ordering schedule (MSBOS) and calculate cost savings achieved. Methods A retrospective cohort study was conducted of all patients who required blood transfusion following primary and revision total hip and knee arthroplasty in 2012 and 2015. A multimodal ERP was introduced in 2015. Cost savings were calculated following the introduction of a new MSBOS. Results During the two-year study period 1467 lower limb arthroplasty procedures were performed. The cross-match to transfusion ratio was 3.6:1 in 2012 and 9.9:1 in 2015. The updated MSBOS resulted in a 46% reduction of cross-matched blood and savings of €54,375 per annum. Conclusion Improved perioperative management in lower limb arthroplasty has reduced blood transfusion rates. Updating blood transfusion practice can result in considerable savings in blood, resources and costs.
