 Service evaluation will take the form of a stepped wedge study design, a type of cluster RCT that is particularly well-suited to implementation and health services research. Importantly, the investigators have already successfully implemented this design in health services research at Western Health. The primary research question is to quantify the impact of a dedicated CAP Service delivering consistent and standardized evidence-based care on length of stay, costs, 30- and 90-day readmission rates and mortality.
