Medical Research: What is the background for this study?
Dr. McIsaac: Older age is a well-known risk factor for adverse outcomes after surgery, however, many older patients have positive surgical outcomes. Frailty is a syndrome that encompasses the negative health attributes and comorbidities that accumulate across the lifespan, and is a strong discriminating factor between high- and low-risk older surgical patients. By definition, frail patients are “sicker” than non-frail patients, so their higher rates of morbidity and mortality after surgery aren’t surprising. However, frailty increases in prevalence with increasing age, so as our population ages we expect to see more frail people presenting for surgery. Our goal was to evaluate the impact of frailty on postoperative mortality at a population-level, and over the first year after surgery to provide insights that aren’t available in the current literature, which largely consists of single center studies limited to in-hospital and 30-day outcome windows.
