Andy is an academic geriatrician with research interests in frailty, delirium and dementia. He is currently deputy lead for the Yorkshire & Humber NIHR CLAHRC Older People’s Theme, entitled ‘Primary care-based management of frailty in older people’.
Andy is CI for an NIHR Programme Grant to optimise and evaluate personalised care planning for older people with frailty and CI for the NIHR HTA-funded Home-based Extended Rehabilitation for Older People (HERO) trial. Andy is also CI for the Community Ageing Research 75+ (CARE 75+) multi-site cohort study to investigate frailty, disability and quality of life trajectories in older age, and evaluate interventions to improve outcomes using a novel ‘trial within cohort’ (TWiCs) design.
Andy led the development, validation and implementation of the award winning and NICE-recommended electronic frailty index (eFI) using data from around 1M UK patients contained in the ResearchOne and THIN primary care research databases.
Key publications include a 2013 Lancet seminar review on frailty in elderly people and a Cochrane review on interventions for preventing delirium in older people in long-term care. Andy was a member of the 2016 NICE multi morbidity guideline development group, the 2010 NICE delirium guideline development group and the NHS Evidence advisory panel. Andy referees applications for the NIHR and MRC, and is a reviewer for the Lancet, BMJ and Age & Ageing journals.
