Abstract
Venous thrombo-embolism is a common complication following hip replacement. The recently-published pulmonary embolism prevention study reported that aspirin decreased the fatal pulmonary embolism rate in patients with femoral neck fractures. In addition, new products (synthetic factor X-inhibitor Fondaparinux and direct thrombin-inhibiter Desirudin) have been reported to be more effective than low-molecular-weight heparin in preventing asymptomatic DVT. We thought it important to update the 1997 survey on thrombo-embolism prophylaxis by British Orthopaedic Surgeons.
A single page questionnaire was sent to 1308 members of the British Orthopaedic Association who are consultant orthopaedic surgeons. Those who did not respond received a reminder. We had a 72% response rate.
All surgeons use some form of prophylaxis, with 85% using pharmacological agents. Low-molecular-weight heparin is used by 55% of surgeons, while 20% use only aspirin. Fewer than 1% (five consultants) use early mobilisation and nearly 2% (13 consultants) use graded stockings and early mobilisation as their only prophylactic measures. Unit policies govern 74% of surgeons. In the last 3 years, 30% have changed their regime.
Most British orthopaedic surgeons still use pharmacological thromboprophylaxis. The use of aspirin has increased from 5% to 30%. Aspirin is often combined with a mechanical prophylactic. The use of intermittent calf compression has increased from 3% to 22% and of foot pumps from 12% to 19%. The use of low-molecular-weight heparin has fallen by 10%.
