Technology and health care for the elderly medical research studies
We facilitate evidence-based research, knowledge sharing and clinical practices that improve healthcare outcomes for older Canadians living with frailty, their families and caregivers.

Frailty is a condition that describes the build-up of problems across multiple body systems, and is common as people age. Having frailty before surgery increases the risk of a bad outcome, and older patients have surgery more often than any other age group. Unfortunately, clinicians don’t know what the best tool to diagnose frailty before surgery is.

To improve how older people recover after surgery, clinicians need to be able to identify people living with frailty. However, we don’t know what tool is best at identifying people who are likely to have a complication after surgery.

The goal of the project was to identify differences between two leading frailty tools in their accuracy and ease of use for patients and clinicians. These new discoveries will be provided to clinicians to help them choose which frailty tool to use before surgery to identify older patients at a high-risk of bad outcomes after surgery.
