Comprehensive geriatric assessment in perioperative care: a protocol for a systematic review and qualitative synthesis

INTRODUCTION: Comprehensive geriatric assessment (CGA) is an intervention that has been deployed in the perioperative setting with the aim to improve outcomes for older patients admitted to hospital. Older patients undergoing surgery are more likely to have postoperative complications, a longer hospital stay and be discharged to a care facility. Despite the increasing application of this intervention within surgical services, the evidence for CGA remains limited in this group. The aim of this systematic review is to describe CGA as in intervention applied to surgical populations in randomised controlled trials (RCTs) as well as the outcomes assessed. METHODS AND ANALYSIS: A systematic search of RCTs of CGA in surgery will be run in Embase, Medline, CINAHL (Cumulative Index to Nursing and Allied Health Literature) and Cochrane library. Further articles will be identified from reference lists in relevant studies found in the search. A narrative synthesis will be undertaken outlining specialties included, detailed descriptions of the intervention and outcomes. ETHICS AND DISSEMINATION: No ethical approval is required. The results of this review will be published and used as the basis of work to optimise this intervention for future trials in surgical populations. PROSPERO REGISTRATION NUMBER: This review is registered with PROSPERO CRD42020221797.
