|Title:||Disparities in post-operative mortality between Māori and non-Indigenous ethnic groups in New Zealand||Authors:||Gurney, J
|Source:||134(1542):15-28||Abstract:||Aim To describe disparities in post-operative mortality experienced by Indigenous Māori compared to non-Indigenous New Zealanders. Method We completed a national study of all those undergoing a surgical procedure between 2005 and 2017 in New Zealand. We examined 30-day and 90-day post-operative mortality for all surgical specialties and by common procedures. We compared age-standardised rates between ethnic groups (Māori, Pacific, Asian, European, MELAA/Other) and calculated hazard ratios (HRs) using Cox proportional hazards regression modelling adjusted for age, sex, deprivation, rurality, comorbidity, ASA score, anaesthetic type, procedure risk and procedure specialty. Results From nearly 3.9 million surgical procedures (876,976 acute, 2,990,726 elective/waiting list), we observed ethnic disparities in post-operative mortality across procedures, with the largest disparities occurring between Māori and Europeans. Māori had higher rates of 30- and 90-day post-operative mortality across most broad procedure categories, with the disparity between Māori and Europeans strongest for elective/waiting list procedures (eg, elective/waiting list musculoskeletal procedures, 30-day mortality: adj. HR 1.93, 95% CI 1.56–2.39). Conclusion The disparities we observed are likely driven by a combination of healthcare system, process and clinical team factors, and we have presented the key mechanisms within these factors.||URI:||http://hdl.handle.net/11055/1110||ISSN:||1175-8716||Journal Title:||The New Zealand Medical Journal||Type:||Journal Article||Study/Trial:||Study|
