About this trial
A postoperative high-acuity model of care (ARRC) has been shown, in a prospective cohort study of approximately 850 patients, to produce a marked improvement in patient and hospital outcomes, and hospital costs, in medium risk patients (Ludbrook G et al., JAMA Surgery 2023).
The goal of this observational study is to examine the outcomes after non-cardiac surgery of a larger group of medium risk patients receiving different forms of care -ARRC and usual ward care. The main questions it aims to answer are:
what are the outcomes for patients and hospital after the different forms of care, who receives benefit from high acuity care, what underlies the improved outcomes seen with high acuity care.
