Quality information

Missing data: Since 2003, capitation payments made via PHOs have progressively replaced fee-for-service claiming. Now GMS claims are only made for a limited number of healthcare user visits of specific types.

Other quality issues: A large number of GMS records submitted to the IDI have identical fields and were identified by Statistics NZ as potential duplicate records. It is not known whether these records are duplicates or legitimate records. The MOH is currently investigating further and will update the IDI metadata when more information is known. Privacy, security, or confidentiality issues Privacy, security, and confidentiality issues are covered in chapters 2 and 5 in Microdata output guide. The GMS claims table that is accessible to researchers do not contain any name or address information to identify an individual. All researchers who have access to the GMS claims data have had their research proposals assessed using Statistics NZ’s microdata access protocols. Only approved researchers who have been granted access by Statistics NZ and the Ministry of Health may view the GMS claims data. Read Statistics NZ’s microdata access protocols. All outputs produced from GMS claims data must be aggregated and counts suppressed if the underlying unrounded count is fewer than six.
