Professor Andrew Clegg

Profile

I am Head of Ageing and Stroke Research at the University of Leeds and Honorary Consultant Geriatrician at Bradford Royal Infirmary. I am Director of the global Ageing Research Trialist (ART) collaborative, established to support individual participant data meta-analysis in ageing research, and Co-Director for Health Data Research UK (HDRUK) North. I lead a large portfolio of ageing-related research, with a focus on frailty as an especially problematic expression of multimorbidity in later life, and medicines optimisation. I hold research grants of around £44M as lead or co-investigator, including leadership of a research theme focused on improving care for older people with frailty in the NIHR Applied Research Collaboration, Yorkshire & Humber and a workstream within the NIHR Leeds Biomedical Research Centre (BRC) Musculoskeletal Theme. Research expertise spans clinical trials of interventions, prognostic modelling using routine data, applied epidemiology and evidence synthesis. I am CI for the Personalised Care Planning for Older People with Frailty (PROSPER) NIHR-funded Research Programme, the Community Ageing Research 75+ and Wellbeing in Later Life in Bradford longitudinal cohort studies study with routine data linkage and co-CI for the NIHR HTA-funded Comprehensive Geriatric Assessment for Older People with Heart Failure and Frailty (CHART) trial. I previously led the development, validation and national implementation of the multi award-winning and NICE Multimorbidity Guideline-recommended electronic frailty index (eFI) using data from around 1M UK patients contained in the ResearchOne and THIN primary care research databases, with major impact on UK health policy and selected as a 2022 National Medical Schools Council Impact Case Exemplar.

I am a current member of the MRC Ageing Research Steering Group, supporting development of future activities in ageing research. I am also co-lead for the NIHR National Ageing, Dementia and Frailty Priority Theme, supporting national implementation of prioritised interventions into routine practice, and co-investigator with the NIHR Policy Research Unit for Older People and Frailty. I am a current member of the NICE Falls Prevention Guideline Development Group. Previous roles include as member of the NICE Multimorbidity Guideline Development Group, NICE Delirium Guideline Development Group, and joint Centre for Perioperative Care & British Geriatrics Society guideline on Perioperative Care for Older People with Frailty.
