Research profile and key clinical specialties

I am Professor of Geriatric Medicine at the University of Leeds, Honorary Consultant Geriatrician at Bradford Royal Infirmary, and Associate Director for Health Data Research UK North.

I lead a large portfolio of ageing-related research as part of a multidisciplinary team of researchers, with a focus on frailty in older people and medicines optimisation.

Our work spans clinical trials of interventions, prognostic modelling using routine data, applied epidemiology and evidence synthesis.

A leading example of our work is the development and national implementation of the multi award-winning and NICE-recommended electronic frailty index (eFI), with major impact on UK health policy.

Two key publications

  • Mehdizadeh D, Hale M, Todd O, Zaman H, Marques I, Petty D, Alldred DP, Johnson O, Faisal M, Gardner P, Clegg A. 2021. Associations Between Anticholinergic Medication Exposure and Adverse Health Outcomes in Older People with Frailty: A Systematic Review and Meta-analysis. Drugs – Real World Outcomes.
  • Clegg A, Bates C, Young J, Ryan R, Nichols L, Teale EA, Mohammed MA, Parry J, Marshall T. 2016. Development and validation of an electronic frailty index using routine primary care electronic health record data. Age and Ageing. 45(3), pp. 353-360

Possible PhD projects

  • Improving prescribing of anticholinergic medications for older people in hospital
  • Development and feasibility testing of a targeted intervention to sustain independence for older people

I am an experienced, supportive supervisor, also leading an NIHR Applied Research Collaboration Doctoral Research Network. I sit on the Dunhill Medical Trust Fellowship panel.
