    3. Once submitted, your request will be reviewed. The review process will depend upon the type of data requested
      a) Data requests that require individual ethics approval, data linkage, are multi-regional or national, or are for non-audit purposes will be reviewed by the CAG. Your data manager will notify you of the decision. This typically takes one to two months.
      b) Data requests for one region (i.e. local clinical specialist/hospital use and audit data). Data managers and the local breast cancer specialist can extract their patient data for audit purposes or for use at a clinical level. This information may only be used internally by the patient carer’s institution and may not be published. The applicant will gain ethical approval from their regional governance group as required. For audits that will be published or is part of a pilot study, then institutional (hospital or university) ethical review may be required. If required, the request may be referred onto the CAG.

    How does the Clinical Advisory Group (CAG) assess a data request?

    The CAG is responsible for the scientific, ethical and cultural review of all applications for data on Te Rēhita, the National Register, except for local data requests. The CAG also takes into account:

    • The extent to which it will improve treatment and outcomes
    • Whether it duplicates or overlaps with previous or current research
    • Whether the findings will be published/how the data will be used
    • Whether there will be any conditions, e.g. formal acknowledgement, review of draft report prior to publication, costs etc.
