ANZICS CTG Endorsed Study

COMPASS

The clinical outcomes measurement in perioperative medicine, anaesthesia & surgery study

Study Description

COMPASS aims to develop a perioperative mortality risk prediction model for adults undergoing inpatient noncardiac surgery in Australia, based on the Surgical Outcome Risk Tool (SORT) from the United Kingdom and its New Zealand adaptation, NZRISK. Three additional candidate variables will be tested in the model, including frailty, socioeconomic status, and Indigenous status. Recognising that risk is dynamic, we also plan to externally validate the Surgical Apgar Score (SAS), calculated at the end of surgery, and investigate the interaction between SORT and SAS in identifying high- risk surgical patients.

Project Status 

Due to the Covid-19 pandemic, our methodology has changed to a cohort study using a large data set obtained from AIHW rather than collecting primary data via anaesthetists at participating hospitals.                                             Ethics approvals are in place, final governance approvals are being sought, and the project is hoped to be complete before the end of 2021.
