Supporting data quality

In 2014, the National Joint Registry (NJR) started a review of its current understanding of data quality in the registry and how to increase data completeness, timely submission and data accuracy further. This is to ensure that the information held in the NJR can be used effectively at all levels of analysis; nationally, regionally and at hospital and individual surgeon level for the benefit of patients, surgeons, hospitals and implant suppliers and research programmes.

This work is summarised in the NJR's Supporting data quality strategy document and covers all of the areas that affect the quality of data including exisiting activities and new initiatives that was implemented over the subsequent years.

This web page will also be a hub for information on one of the national programmes of work that will be supporting quality hospital data collection, entry and accuracy through local audit.

NJR data completeness and quality audits

Data quality and validation are essential components of any audit or scientific research.  As such, the NJR’s programme of work to improve the quality of our data has been a key focus in recent years, driven through the NJR’s ‘Supporting Data Quality Strategy’. 

Key to this strategy has been the NJR’s national programme aimed at assessing data completeness and quality within the registry.  Known more simply as the Data Quality Audit, the programme, which completed its second year in July 2017, has allowed the NJR to compare patient record for record procedures recorded in local hospitals’ databases to the registry, with the aim of investigating the accurate number of arthroplasty procedures submitted compared to the number carried out. 

The National Joint Registry will be continuing its audit programme to retrospectively check the quality of data and the commitment to patient safety from all hospitals reporting to the registry on an annual basis.

Understanding data as a tool for quality improvement is an important part of the ongoing data-driven change that is happening right across the orthopaedic sector. NJR data is a fundamental driver to inform improved quality of care for patients. Therefore, it is imperative that the data provides an accurate picture of what is happening locally so that the right decisions are made.


Introductory videos

Please see the links below to watch two short surgeon and hospital videos. These short clips, recorded in 2015 from the NJR's Medical Director, Mr Martyn Porter, introduced the data checking process as well as the activity and benefits associated with participating in the data completeness and quality audit programme. Whilst some of the processes have since been changed to further support hospitals, the principles outlined in the videos are still relevant and of interest:
