Brief summary

Currently, there is no widely used clinical tool for anaesthestists to predict perioperative mortality that has been validated in New Zealand patients. We aim to validate the Surgical Outcome Risk Tool (SORT), a parsimonious, 6 risk factor multivariate model used in the UK, in a New Zealand cohort. We also aim to extend the model to include gender and ethnicity to tailor the model to New Zealand conditions. We will also aim to derive extended models incorporating one and two year mortality as well as 30 day mortality.

Interventions

NZRISK will provide a multivariate risk model based on data from July 2011 to June 2016 of the New Zealand Ministry of Health National Minimum Dataset (NMDS. Covariates will include age, gender, ASA, acuity, specialty, surgical severity, ethnicity and cancer status.
