Scope

Purpose
The purpose of the PHO Enrolment Collection is to provide a national collection that holds Primary Healthcare System (PHCS) patient enrolment data for the following uses:

• to assist PHOs, DHBs and the Ministry of Health in reporting and monitoring patient enrolment under the PHCS
• to provide PHOs, DHBs, the Ministry of Health and health researchers with population data to assist with population health research
• to assist PHOs in examining and improving the quality of their enrolment information.

Start date

The PHO Enrolment Collection was established in 2005.

Guide for use

The dimensions in the datamart are codes and descriptions, based on reference data. It may be unique to the datamart or it may be common across several systems. Dimension data includes items such as Provider IDs, Healthcare User IDs, and ethnic groups.
The facts in the datamart are “events” and “enrolments”, based on the PHO registers and FFSvc data captured by HealthPAC within the General Transaction Processing System (GTPS).
For more information, refer to the PHO Data Dictionary.
Extract files are sent to NZHIS where they are loaded into the datamart tables to facilitate reports and queries.

Contact information

For further information about this collection or to request specific datasets or reports, contact the NZHIS Analytical Services Team, on ph 04 816 2882, fax 04 816 2898, or e-mail inquiries@nzhis.govt.nz.

Collection methods – guide for providers

The PHO Enrolment Collection holds and provides access to two key elements of PHCS information:

• copies of all “Enriched PHO Enrolment Registers” as sent from HealthPAC to PHOs; any register adjustments are also applied to the collection
• copies of all “Fee for Service Wash-up” information as sent from HealthPAC to PHOs; FFS wash-up cost adjustments are also applied to the collection.

Frequency of updates

The PHO datamart receives monthly extracts from HealthPAC.

Security of data

The PHO Enrolment Collection provides access to different health sector organisations as follows:

• PHOs can access their own enrolled patient information and the FFS wash-up costs for these patients
• DHBs, the Ministry of Health and authorised researchers can access non-identifiable enrolled patient information and non-identifiable FFS wash-up costs
• NZHIS and specially authorised Ministry of Health data analysts can access all information held in the collection.

Privacy issues

The PHO Enrolment Collection has been designed to protect patient information as required by the Health Act 1956, the Privacy Act 1993 and the Health Information Privacy Code 1994. This ensures that access to identifiable patient information is limited to the PHO where the patient is enrolled and selected Ministry of Health personal specifically authorised by NZHIS.

National reports and publications

NZHIS releases monthly standard reports for DHBs via the HIN.

Data provision

Customised datasets or summary reports are available on request, either electronically or on paper. Staff from the NZHIS Analytical Services team can help to define the specifications for a request and are familiar with the strengths and weaknesses of the data.
The NZHIS Analytical Services team also offer a peer review service to ensure that NZHIS data is reported appropriately when published by other organisations.
There may be charges associated with data extracts.
