Tess Harris is a Professor of Primary Care Research in the Population Health Research Institute at St George's, University of London and a member of the Primary Care Epidemiology Group within the research institute. She specialises in health promotion research in primary care, particularly trials to increase physical activity in adults and older adults and also in primary care database research.
Her MD, awarded in 2005, examined depression, disability and use of primary care services by older people and linked survey and routine general practice data. She has been at St George's since 1994, when she was appointed as a lecturer. Prior to this, Dr Harris graduated in Medicine from St George's in 1988, completed her vocational training in General Practice, and gained her Membership of the Royal College of General Practitioners with distinction in 1992. Following this she worked in India for a year, training village health workers and working on a primary health care programme. In 1994 Dr Harris gained an MSc in Epidemiology from the London School of Hygiene and Tropical Medicine with a distinction.
She works part time as a GP at Sonning Common Health Centre in Oxfordshire, alongside her academic work at St George's, University of London, and has edited a book on managing older people in primary care (Oxford University Press 2009). Professor Harris currently sits on five Programme grant / Trial Steering Committees for the National Institute for Health Research. She also recently served on the NIHR Health Technology Assessment Programme Prioritisation Committee until July 2019.
Tess Harris is a Professor of Primary Care Research in the Population Health Research Institute. Her research focuses on health promotion, particularly physical activity trials in primary care and on the use of primary care databases to answer important questions about health.
Physical activity is vitally important for physical and mental health, yet activity levels, particularly in older adults, are very low. Professor Harris has been chief investigator for two large primary care randomised controlled trials of pedometer-based walking interventions, both providing objective physical activity outcome measures and novel long-term follow-up data. These are:
• PACE-Lift: (Pedometer Accelerometer Consultation Evaluation-Lift). A randomised controlled trial of a complex walking intervention in 60-75 year olds, funded by Research for Patient Benefit, National Institute for Health Research, (NIHR) May 2011-January 2014. It showed significant increases in both step-counts and time in moderate-to-vigorous physical activity for the intervention group compared to controls, sustained at one year. Four-year follow up was undertaken from October 2015-October 2016 and also showed persistent trial effects.
• PACE-UP: (Pedometer And Consultation Evaluation –UP). A randomised controlled trial of a pedometer-based walking intervention with and without practice nurse support in 45-75 year olds, funded by the Health Technology Assessment Programme, NIHR March 2012-May 2017. Initial trial results at one year showed favourable effects of both nurse and postal interventions compared to controls in terms of both step counts and time in moderate-to-vigorous physical activity. Further funding for three-year follow up was awarded and showed persistent effects of the intervention on physical activity levels. Recent work combining the trials and examining long-term health outcomes using data from primary care records showed that the interventions significantly reduced the rate of cardiovascular events and fractures at 4 year follow-up.
The primary care database work is in collaboration with other Primary Care Epidemiology Group members and is focusing on the following areas: diabetes and infections; investigation of compression of morbidity and care in the last year of life; medicines optimisation in patients with multi-morbidity; and epidemiology of neuromuscular disorders. Other recently published work has examined healthcare use and health outcomes for patients with learning disability (Health Services and Delivery Research, NIHR), quality of care for care home patients (BUPA foundation) and health outcomes following partner bereavement (Dunhill Trust).
