Frailty assessment should now be as much a standard as cardiorespiratory evaluation pre-op. No gold standard exists and one qualitative tool is the Clinical Frailty Scale – CFS link
This study on unscheduled surgeries in those over 65 years of age used the CFS as well as other outcome prediction tools.
It found that duration of hospital stay was independently associated with: pre‐operative ASA physical status; surgical severity; peri‐operative E‐POSSUM score; and SORT. Duration of stay was also associated with the CFS, but not independent of these variables.
Future refining of frailty assessment tools may lead to better prediction scales.
