Data Completeness and Quality

Data Completeness and Quality

Information about the key indicators of data completeness and quality

It is mandatory for the providers of joint replacement surgery listed below to collect and submit data to the registry

• All NHS trusts and foundation trusts within the jurisdiction of NHS England
• All hospitals within the jurisdiction of NHS Wales 
• All hospitals in Northern Ireland performing procedures funded by Health and Social Care Northern Ireland (HSCNI) 
• All independent sector hospitals in England and Wales

Performance against the three key indicators of data quality (compliance, consent, and linkability) varies slightly throughout the year. Performance against the three indicators was lower in 2020/21 than other years due to the COVID-19 pandemic. Current unit-level performance against these key indicators is available in the Downloads area.

The number of procedures submitted, with the corresponding consent rates, for each hospital are provided through the NJR StatsOnline service. Performance against all indicators is also included in the Annual Clinical Report provided to trust and health board senior management and to independent healthcare companies. Surgeons are also able to access Annual Clinical Reports for those hospitals in which they practice.
