Change Request |
Reference: | Change Request 323 |
Version No: | 1.74 |
Subject: | DSCN 35/2003 - National Joint Registry Minimum Data Set |
Type of Change: | Incorporation of a Minimum Data Set into the NHS Data Dictionary |
Effective Date: | 1 April 2003 |
Reason for Change: | Incorporation of elements from the National Joint Registry Minimum Data Set was required in the NHS Data Dictionary. |
Hip and knee joints comprise the largest number of joint replacements used in the UK and both are subject to a high proliferation of different implant types that commonly lack data on their long-term effectiveness.
The National Joint Registry is a keystone to delivering the commitment of both the Department of Health and the Welsh Assembly Government to improve the health and wellbeing of the population and is a vital tool for improving clinical standards for hip and knee replacements.
At the heart of the NJR is a database of information collected from all the hip and knee replacement procedures in England and Wales.
The NJR data is being used to bring direct benefits to patients by:
- Improving patient awareness of the outcomes of hip and knee joint replacement
- Finding out how long the different joint replacements last
- Helping to identify individual patients who have received an implant if there is a need for urgent clinical review.
The National Joint Registry went live on the 1st April 2003 and this DSCN has incorporated the National Joint Registry Minimum Data Set into the NHS Data Dictionary.
The National Joint Registry website is accessible at: http://www.njrcentre.org.uk/index.

National Joint Registry Minimum Data Set Overview |
About the National Joint Registry:
Hip and knee joints comprise the largest number of joint replacements used in the UK and both are subject to a high proliferation of different implant types that commonly lack data on their long-term effectiveness. The NJR is a keystone to delivering the commitment of both the Department of Health and the Welsh Assembly Government to improve the health and wellbeing of the population and is a vital tool for improving clinical standards for hip and knee replacements. It will benefit patients, clinicians and the orthopaedic industry. At the heart of the NJR is a database of information collected from all the hip and knee replacement procedures in England and Wales.
Is the NJR Compulsory?
If a hospital is in an NHS Trust, then they are expected by ministers to comply. If the hospital is Independent, then the NJR is compulsory and enforced by the National Care Standards Commission.
Further Information:
Further information on the background to the National Joint Registry can be found in the summary of a consultation exercise, which can be accessed on the Department of Health website.
