Is a preoperative group and save necessary for enhanced recovery joint replacement patients?

To consider the financial benefit to the authors' trust of omitting a preoperative group and save in enhanced recovery arthroplasty patients, and to estimate the scope for national savings. Patient safety was considered to determine acceptability for routine practice.

A total of 121 patients receiving a total knee replacement or total hip replacement on the authors' enhanced recovery protocol were selected. Pre- and postoperative haemoglobin levels were obtained. The transfusion team were contacted when the postoperative haemoglobin level was ≤8 g/dl to determine whether blood products had been issued. Costs for group and save were obtained from the pathology department.

Mean postoperative reduction in haemoglobin level was 2.6 g/dl (P≤0.001) and 2.1 g/dl (P≤0.001) for total hip replacement and total knee replacement respectively. No patients were transfused. One group and save costs £12.00, and omission of this test in these patients would have saved £1452.00. Potentially, £1 605 408 could have been saved in the 133 784 patients undergoing NHS arthroplasty in 2012. Group and save omission would not affect management of intraoperative haemorrhage where O negative blood would be available. If a transfusion is required postoperatively it would take 100 minutes to issue crossmatched blood - a time delay unlikely to compromise patient safety.

These results suggest that a preoperative group and save could be omitted in arthroplasty patients on this enhanced recovery programme to prevent needless expenditure, but more long-term follow up is required to ensure patients are not put at risk.
