Best Practice Tariff

NJR Best Practice Tariff

Since 2014, NJR data has been used for determining NHS provider compliance with the Best Practice Tariff scheme for primary hip and knee replacements in England. We measure the proportion of cases reported to the NJR, compared to cases reported to other sources of comparative data, such as through Hospital Episode Data (HES). This provides the basis for us to report on the compliance and completeness of the data with regard to the tariff. Data presented on this page below relates to a twelve-month period and is updated quarterly: April, July, October and December.

NJR Compliance

NJR Compliance measures the proportion of cases reported to the NJR, compared to cases reported to other sources of comparative data, such as HES.  Where cases are outsourced to another provider, but reported through HES by the originally commissioned trust, some procedures may be reported as ‘missing’ from the registry.  This is because the corresponding NJR record will have been submitted by the outsourced provider and the HES record does not accurately record the identity of that outsourced provider. 

Outsourcing cases to another provider – advice on codes to use

Where cases are outsourced to another provider, but reported through HES by the originally commissioned trust, some procedures may be reported as ‘missing’ from the NJR, as outlined in the wording above. To prevent such cases from being reported as ‘missing’ from the registry, it is essential to complete the ORGANISATION SITE IDENTIFIER OF TREATMENT code field in SUS with the NACS code (formerly the ODS code) of the organisation to which the procedure has been outsourced. Completion of this field enables the NJR to exclude the record from the data it expects to be recorded for the trust, whilst also enabling the NJR to ensure that the corresponding record has been submitted by the outsourced provider.

Another important reason to complete the SITETREP field in SUS with the appropriate ORGANISATION SITE IDENTIFIER OF TREATMENT code whenever anything relevant is sub-contracted to other hospitals, is that it ensures that any subcontracting activity is not only picked up but also that the subscription cost for this particular procedure will be correctly attributed. We are unable to track any movements in activity regarding this without this field being completed. It ensures NJR compliance information is accurate in relation to achieving Best Practice Tariff.
