nzRisk
nzRISK has been developed to be a simple and easy to use risk calculator based on the New Zealand population. It has been compiled using data from over 270,000 patients aged 18 or over undergoing non-cardiac surgery. It includes eight risk factors that can be entered below to give a 30 day, one and two year estimate of mortality. Each risk factor is associated with mortality and improves the performance of the calculator.
