Comprehensive Geriatric Assessment in the perioperative setting; where next?

Abstract

Comprehensive Geriatric Assessment (CGA) is being employed in the perioperative setting to improve outcomes for older surgical patients. Traditionally CGA is delivered by a geriatrician led multidisciplinary team but with the acknowledged workforce challenges in geriatric medicine, it has been suggested that non-geriatricians may be able to deliver CGA. HOW-CGA developed a toolkit to facilitate the delivery of CGA by non-geriatricians in the perioperative setting. Across two hospital sites uptake and implementation of this toolkit was limited by a potential lack of face validity, behavioural and cultural barriers and an acknowledgement that geriatric medicine expertise is key to CGA and optimisation. In-keeping with this finding there has been an observed expansion in geriatrician led CGA services for older surgical patients in the UK. In order to demonstrate the effectiveness of perioperative CGA services, implementation science should be combined with health services research methodology and the use of big data through linked national audit.
