Abstract
Background Prescriptive guidelines for selection of implants for hip arthroplasty are likely to become increasingly established, on grounds of safety, cost and effectiveness. Such guidelines were introduced in the UK by the National Institute of Clinical Excellence (NICE) in 2000. Most departments were non-compliant in one or more respects, and knowledge of the recommendations was limited among clinicians. Concern exists that the recommendations may replace the Bolam Test in cases of clinical negligence in future.
Materials and Methods The recommendations of NICE, from the initial documentation to the present, were scrutinised alongside experience of other nationally-funded or managed healthcare systems in Europe and North America. The evolution of guidance from 1999 onwards, together with the areas of potential difficulty were identified.
Results Potential difficulties were encountered in relation to a number of implants in widespread use in the UK, particularly in relation to the choice of acetabular component (cup), despite the fact that cup loosening accounts for a third of revisions. The use of cup and stem from different manufacturers was also identified as a cause of concern.
Discussion Departments face a choice of adopting the recommendations of NICE in their entirety or continuing with established practice, with the attendant risk of future litigation should certain implants prove to be unacceptable as clinical results become available through the National Registry. Continuation with established practice may be acceptable, even in respect of implants not recommended by NICE, provided data collection activity is maintained. We propose an algorithm through which individual departments may maintain compliance with NICE without altering departmental practice.
