Lay summary
In New Zealand (NZ), Māori are less likely to be diagnosed with prostate cancer but are more likely to have poorer survival outcomes once diagnosed. PCOR-NZ, a national registry for prostate cancer, was established in 2015 with the aim of collecting and using data on care provided and outcomes for men with prostate cancer in NZ. It has collated the care data of more than 18,000 prostate cancer patients to date and has achieved very high coverage rate of prostate cancer cases diagnosed in NZ. Previous works using PCOR-NZ data have identified ethnic inequities in cancer assessment and treatment received by prostate cancer patients in NZ. This study sought to use PCOR-NZ data to identify ethnic inequities in the quality of surgical care of prostate cancer patients in NZ. Findings would be used towards knowledge translation and developing health delivery interventions that would be examined in future health delivery research.
