CRRT programme elements are shaded from white to light grey to dark grey as per the Donabedian framework of structure, process and outcome. Specific CRRT KPIs are in bold. Benchmarks have been taken from our internal and external validation of the KPIs. Our primary outcome will measure the performance of specific CRRT process KPIs.
