This project looks at how fairly health services for kidney transplantation are delivered in New Zealand. Sometimes the way health services are organised means some people don’t benefit as much as others. We are interested in any advantages or disadvantages for different groups of people getting on the kidney waiting-list, the time they need to wait for a transplant, and what happens to them after their transplant. Differences might be due to where they live, their sex, their race, or their other health problems. We will use existing health and government data, anonymised and linked together, to understand whether transplant services work equally well for all New Zealanders. Initially, we will look at how the waiting list works for kidney transplantation, what happens to living kidney donors after they donate a kidney, and whether people with mental health problems have fair access to transplantation.
