AbstractFive hundred orthopaedic surgeons and 336 anaesthetists were surveyed to assess current UK attitudes towards transfusion practice following arthroplasty surgery. Seventy-two percent of surgeons and 73% of anaesthetists responded to the survey. In an uncomplicated patient following total hip arthroplasty, 53.2% of surgeons and 63.1% of anaesthetists would transfuse at or below a haemoglobin (Hb) level of 8 g/dL. Surgeons tended to be more aggressive in their attitudes, with a mean transfusion threshold of 8.3 g/dL compared to 7.9 g/dL for anaesthetists (p<0.01), and with 97% of surgeons transfusing two or more units compared to 78% of anaesthetists (p<0.01). This threshold Hb increased if the patient was symptomatic (surgeons 9.3 g/dL, anaesthetists 8.8 g/dL, p<0.05) or was known to have pre-existing ischaemic heart disease (surgeons 9.0 g/dL, anaesthetists 9.2 g/dL, p<0.05). A wide variability in attitudes and practices is demonstrated, and the development and adoption of consensus guidelines needs to be encouraged if efforts to reduce the use of blood products are to succeed.
