National Joint Registry:
Better joint replacement surgery

Supporting innovation, providing clinical controls and giving patients confidence about the future, the National Joint Registry helps to improve outcomes for patients having joint replacement surgery in England, Wales, Northern Ireland and Isle of Man.

About the National Joint Registry (NJR)

The NJR was set up by the Department of Health and Welsh Government in 2002. It collects information on joint replacement operations and monitors the performance of implants, hospitals and surgeons. Northern Ireland joined in 2013 and the Isle of Man in 2015.

The Healthcare Quality Improvement Partnership (HQIP) manages the Registry on behalf of the Department of Health.

NPS has delivered the NJR service since April 2006. Since then, it has evolved from a data entry solution to a full business intelligence platform with extensive reporting services.

Continual service improvement

The NJR contains demographic data, like age and gender. It also captures information about the physical status of patients, the surgeon, the reasons for implantation, the surgical approach and details about the implant.

The register helps to monitor the performance of the wide range of implants as well as the effectiveness of the surgery. This benefits patients and clinicians and supports regulators and the orthopaedic industry.

The services NPS provide to HQIP and other stakeholders include on-site support and advice around governance, patient confidentiality and data protection.

Business intelligence

Through a separate business intelligence platform, NPS provide extensive reporting services. This includes secure, online services for clinicians, hospital management and orthopaedic device manufacturers, as well as the NJR’s Reports Online service and the Consultant Outcomes Publication.

NPS also provide a dedicated data quality management team which manages ad hoc requests for information for research and analysis, including linking to external datasets where necessary.
