Implementation of the NICE guidelines for venous thromboprophylaxis; a national survey of hip surgeons.

The 2007 United Kingdom National Institute for Health and Clinical Excellence (NICE) thromboprophylaxis guidelines concerning hip arthroplasty remain contentious in spite of significant evidence. A survey among British Hip Society members was performed to investigate the impact of these guidelines. Information on thromboprophylactic measures before and after guideline publication was gathered for three categories; Total Hip Replacement (THR), hip fracture and high-risk patients (as defined by NICE). The response rate was 185/250 (74%). All responders used thromboprophylaxis, but only 44%, 22% and 7% indicated they were currently acting in accordance with guidance for THR, high risk and hip fracture groups respectively. Only 19%, 14% and 14% had changed their practice since publication of the guidance in THR, high risk and hip fracture groups respectively. The effects of national guidance in influencing thromboprophylactic protocols have therefore been limited. The reasons were not investigated in this survey.
