Identifier Management

TWB is an extension of the Primary Mental Health Care Minimum Data Set (PMHC MDS); the current PMHC MDS Identifier Management rules apply. These are available to be viewed at https://docs.pmhc-mds.com/data-specification/identifier-management.html.

Managing Keys

The TWB Critical Incident Key, TWB Recommendation Out Key, Collection Occasion Key and Measure Key will be created and managed by Provider Organisations.

The PMHC MDS specification requires each of these keys to be unique and stable at the Provider Organisation level. See above links for the specification requirements for these data elements:

Each record needs to be assigned a unique key in order to facilitate adding/updating/deleting each item when uploading/entering data. These keys will be created and managed by the Provider Organisation.

Where data is being exported from client systems, these keys can be auto generated, providing that a key does not change once it is assigned.

Managing PMHC MDS Episode Key

Each TWB Episode record needs to record the corresponding PMHC MDS episode key in order to link it to an existing episode within the PMHC data and facilitate adding/updating/deleting each item when uploading/entering TWB data.

See below links for the specification requirements for these data elements:

• Episode Key

Identifying TWB-Episode data records

To enable the PMHC MDS to add a TWB-Episode record to a PMHC Episode, the ‘!wayback’ tag must be included on the ‘Tags’ field of all TWB-Episode data records. If not included, the system will automatically include it.

For users inputting data through the PMHC-MDS data entry interface adding this tag will enable the additional TWB specific data entry elements.

For users uploading data where the tag is not included but the upload includes the additional TWB fields, the system will automatically add the tag.
