Background: Comprehensive geriatric assessment (CGA) is a holistic model of care, which proactively identifies and addresses complex and multifactorial needs in older adults. The rapid acceleration in the ageing population means we are depending on CGA to deliver effective, efficient, sustainable and affordable gerontological care. While CGA first emerged as a model of care for frail older adults in hospital, it is proliferating in other specialities (emergency medicine, surgery, orthopaedics, oncology, renal) as well as community, ambulatory care and long-term care settings. Variations in outcome reporting across trials has impacted the synthesis of findings.
Aim: The aim of this research project is to develop an evidence and consensus-based Core Outcome Set (COS) for research studies evaluating the effectiveness of CGA for older adults
Methods: We will adhere to COS development methodology recommendations from the COMET Initiative (Core Outcome Measures in Effectiveness Trials). Meaningful engagement with older adults in their capacity as co-researchers will inform and guide the research process.
The following series of studies will underpin the development of this COS:
A scoping review of trial registries to establish commonly reported CGA outcomes and associated instruments.
A rapid qualitative evidence synthesis on outcomes of importance in research studies with older adults and CGA.
Participatory research methods to identify outcomes relevant to older adults and those important to them, healthcare professionals and research stakeholders
An e-Delphi study and consensus meeting with key stakeholders to reach consensus on inclusion of items in the COS
A literature review and group consensus meeting to establish recommended outcome measures.
Impact: COS for research studies evaluating the effectiveness of CGA has the potential to enhance the conduct and reporting of future clinical trials, systematic reviews and clinical guidelines by facilitating the availability of comparable data and by ensuring outcomes that matter to all stakeholders are represented.
