Planned changes to the NJR Minimum Data Set (MDS)

The set of data fields collected by the National Joint Registry (NJR) is known as the Minimum Dataset (MDS). The majority of MDS data fields relate to the patient's operation details and are collected in the operating theatre. The NJR is planning changes to the NJR MDS. The implementation of MDS Version 7 will see refinement of the data that is collected for primary and revision hip, knee, ankle, elbow and shoulder joint replacement. 

The NJR will write to all hospitals who report to the registry ahead of the implementation of MDSv7, which is expected to come into effect mid-April 2018.

The changes are in response to feedback from data collection staff and orthopaedic surgeons and have been reviewed extensively by the NJR’s Regional Clinical Coordinators Network, orthopaedic surgical society representatives and the NJR’s Steering Committee. The improvements aim to reduce the burden of data collection whilst enhancing the ability of the NJR to analyse the data in ways that more appropriately reflect current clinical practice.
