Venous thromboembolism (VTE) is a serious complication after lower limb injury and surgery. Pursuing prophylactic policies, particularly chemical prophylaxis, has been a debatable issue. In April 2007, the National Institute of Clinical Excellence recommended using chemical and/or mechanical prophylaxis for patients undergoing joint arthroplasty and other orthopedic operations. A list of risk factors predisposing patients to VTE was published. This article discusses the difficulties and methods of implementing the guidelines.

METHODS AND MATERIAL : Patients undergoing lower limb arthroplasty or treatment for femoral neck fractures were included. In total, 9893 patients required prophylactic treatment for VTE.

RESULTS : The maximum readmission rate within 3 months of lower limb arthroplasty with a deep vein thrombosis or pulmonary embolism was reduced from 70% in 2005 to 28% in 2009.

CONCLUSION : The incidence of VTE was reduced to one fifth of that before implementing the National Institute of Clinical Excellence guidelines. Thus, it has been valuable to implement the guidelines.
