Minimum Data Set Version 7

On Monday 4th June 2018, the National Joint Registry will launch version 7 of its Minimum Dataset. Our MDS was last updated in 2014.

The changes are in response to feedback from data collection staff and orthopaedic surgeons and were extensively reviewed by the NJR Minimum Dataset Working Group, chaired by Mr Matthew Porteous, and supported by the NJR Regional Clinical Coordinators Committee.  The change proposals were sent to orthopaedic professional societies: BASK, BHS, BESS & BOFAS for review and approved by the NJR Steering Committee.

The changes have been designed to clarify and enhance NJR data quality rather than increasing the burden on data entry teams.

What should I do to prepare?

We recommend data entry users and HDMs to:

  • Circulate and put into use new data collections above
  • Note and raise awareness of the changes amongst data collection & processing teams within your hospital
  • Ensure that all procedures carried out in FY 17/18 are reporting MDSv6 forms and are submitted by 31st May 2018

Can I use the MDSv7 forms now?

Yes, you can use MDSv7 forms before the 4th June 2018, but you will not be able to input them until the form goes live on that date. We recommend that you start using MDSv7 paper forms in April/May and use the time to ensure that all your MDSv6 forms are input before that date.

What happens if I have procedures carried out in FY17/18 not uploaded by the 31st May?

Once MDSv7 goes live on the 4th June 2018, any outstanding procedures will need to be transferred to MDSv7 forms. You will need to go back to the surgeon to get some information for the new MDSv7 form and then submit as normal. Ideally we would recommend you to start using the MDSv7 paper forms in April/May, ready for entering on the 4th June 2018.
