National survey in the United Kingdom of prophylaxis of deep vein thrombosis for patients with fracture of the neck of the femur.

Thromboprophylaxis continues to be a contentious issue because of a lack of clear answers to pertinent questions. Hence, a survey is helpful in identifying current practices. A national survey in the UK in January 2004 investigated the use of thromboprophylaxis following fracture of the neck of the femur. Responses from 723/1648 (44%) orthopaedic consultants to a postal questionnaire showed that 623 (86%) regularly undertook trauma surgery and 625 (87%) had protocols for prophylaxis of deep venous thrombosis. In all, 555 (89%) consultants followed these protocols routinely and, of these, 276 (50%) regularly used both chemical and mechanical prophylaxis, 235 (42%) used chemoprophylaxis only and 44 (8%) used mechanical prophylaxis only. Among consultants using chemoprophylaxis, 238 (46%) used low-molecular-weight heparin, 148 (30%) used aspirin, 75 (15%) used low-molecular-weight heparin and aspirin, 35 (6%) used unfractionated heparin and 15 (3%) used warfarin. However, 68 (11%) did not use any thromboprophylaxis at all for patients with fractured neck of the femur.
