The Pharmaceutical Collection is a data warehouse that supports the management of pharmaceutical subsidies. It contains claim and payment information from pharmacists for subsidised dispensings.

For further information about this collection or to request specific datasets or reports email data-enquiries@health.govt.nz.

Scope

Start date

Start date

The collection was started in 1 July 1992. Records from before 1996 have been archived, but can be made available on request.

 

Guide for use

Guide for use

The Pharmaceutical Collection has undergone two major changes since 1992:

  • repeat prescriptions were introduced in 1996, and
  • the major drug key changed from Medicode (allocated by Sector Services) to Pharmacode (pharmacy stock code) in 1998.

Other small structural changes are made to the Pharmaceutical Collection each year.

All money values are assumed to be inclusive of GST, unless otherwise stated.

Identification of co-prescribing, which is the analysis of drugs being prescribed and taken together, has been a problem with historical data.
