Explicit rationing of elective services: implementing the New Zealand reforms

In an attempt to make rationing of elective surgery in the publicly funded health system more explicit, New Zealand has developed a booking system for surgery using clinical priority assessment criteria (CPAC). This paper is based on research undertaken to evaluate the use of CPAC. To explore whether the goals of explicit rationing were being met 69 interviews were undertaken with policy advisors, administrators and clinicians in six localities throughout New Zealand. The aims of reforming policy for access to elective surgery included improving equity, providing clarity for patients, and achieving a paradigm shift by relating likely benefit from surgery to the available resources. The research suggests that there have been changes in the way in which patients access elective surgery and that in many ways rationing has become more explicit. However, there is also some resistance to the use of CPAC, in part due to confusion over whether the tools are decision-aids or protocols, what role the tools play in achieving equity and differences between financial thresholds for access to surgery and clinical thresholds for benefit from surgery. For many surgical specialties implicit rationing will continue to play a major part in determining access to surgery unless validated and reliable CPAC tools can be developed.
