ABSTRACT
Elderly surgical population is growing faster than the rate of population ageing. The risk of postoperative complication is higher in this population, the type of complication and the risk indicators are different from younger patients. There is also a huge heterogeneity in the elderly population. The concept of frailty-emerges to explain these specific aspects and to risk stratify older patients. The present work intends to help the anaesthesiologist to take into account the concept of frailty at the preoperative visit. We reviewed, in the light of surgical context, the physiopathology of ageing, the definitions of frailty concept,the current existing strategies for peri-operational optimisation and the different frailty assessment tools. Our conclusions are that preoperative frailty assessment is essential in modern perioperative medicine practice and that the Edmonton Frail Scale stands out from other tools even though it cannot yet be considered as a gold standard.
