Executive summary (across all report areas)

Part One: Annual progress 2014/15

The 12th Annual Report of the National Joint Registry ( NJR) is the formal public report for the period 1 April 2014 to 31 March 2015 and comprises distinct parts.

As part of the continued approach to sharing information about NJR progress, clinical activity and hospital and implant activity, the NJR has again refreshed and built upon its new, dedicated online annual report website ‘NJR Reports’ to showcase annual report data and information.

Some of these data can be found in the slimmer printed report – namely the executive summaries and the full detailed, statistical analysis of outcomes following joint replacement surgery.

A short summary of the NJR’s progress over 2014/15 is included below, with further detail available at www.njrreports.org.uk and in the Chairman’s introduction and Editorial Board Chairman’s foreword.

The total number of procedures recorded in the NJR now exceeds 1.8 million at 31 March 2015, with 2014/15 having the highest ever annual number of submissions at 226,871. This is against a backdrop of sustained data quality, although a high degree of monitoring and support to orthopaedic units is still required.

Overall key performance indicators demonstrated:

  • Overall compliance (case ascertainment) was recorded as 96%
  • Patient consent (to record their details in the NJR) was recorded as 93.8%
  • Linkability (the ability to link a patient’s primary procedure to a revision procedure) was recorded as 92.8%

There have been changes in the NJR systems and processes that relate to these statistics and any comparison on the previous year will demonstrate variation – please see the data completeness and quality indicators section online for further detail.

The evolution of the NJR Steering Committee has continued, with a series of new appointments being made allowing for a number of long-standing members to conclude their final terms of office. In recognition of the great increase in scope and responsibilities of the NJR, the registry also continued the establishment of a revised governance, structure and operating model – seeing the new Medical Advisory and Executive Sub-committees take shape.

Another key achievement has been to continue the work in implementing a revised economic model. Launched from April 2014, the changes not only represented a significant cost saving to the NHS but meant a new, fair and proportionate cost contribution from orthopaedic device manufacturers for services provided through NJR Management Feedback to support post-market implant surveillance.

It should also be highlighted that the reports from the respective Chairman of the Implant Performance Sub-committee and the Surgeon Outlier Sub-committee are available online and outline how outlier analysis is undertaken. They also include the high-level outcomes of the monitoring process for 2014/15 with statistics provided in a new section on activity and outcomes, alongside hospital performance and outlier analyses.

Finally, the NJR remains committed to working for patients and driving forward quality in joint replacement surgery. Further progress and updates will be available at www.njrreports.org.uk and the main NJR website at www.njrcentre.org.uk
