Biography

Tom Marshall graduated MB ChB from the University of Edinburgh in 1987. He undertook clinical posts in hospitals the UK, South Africa and Gibraltar where he acquired his interest in the wider determinants of health and organisation of health care systems. In 1991 he undertook a MSc Health Economics at University of York. Following this he returned to clinical medicine to complete vocational training in general practice and his MRCGP before specialising in public health medicine in Northamptonshire. During this period he completed his MSc in Public Health, obtained the MFPH and spent a total of one year (in 1996 and 1997) working for the WHO Regional Office for Europe on health care systems and health care reforms in European countries.

In 1999 Tom moved to an academic post in public health in University of Birmingham and completed his PhD: an economic evaluation of cardiovascular disease prevention in primary care. In 2003 to 2004 he spent a year as a Commonwealth Fund Harkness Fellow in Health Policy in Harvard Medical School.

From 2005 to 2010 he was Programme Director of the University of Birmingham Master of Public Health. He currently acts as an external examiner for the Imperial College London MPH programme.

Tom’s research interests are diverse. Common themes include his interest in addressing practical and substantial health problems and a focus on primary care. In 2000 his seminal paper on the potential for taxation to influence diet achieved worldwide media coverage and has sparked a number of subsequent papers by other authors. He has published on the use of statistical process control for quality improvement in health care and for monitoring mortality rates in primary care. He has researched patients views and preferences in relation to taking drug treatments to prevent cardiovascular disease. His work on the economics of cardiovascular prevention in primary care has been influential in the 2008 NICE guidelines on lipid lowering. He has published several papers on the effects of variation in the measurement of risk factors on clinical decision making. More recent work has investigated the potential for targeted case finding of patient at high risk of cardiovascular disease using information recorded in electronic primary care records. This is being evaluated in primary care based a cluster randomised controlled trial in the West Midlands. He has also investigated using electronic primary care records for the identification of patients at high risk of suspected colorectal cancer and is interested in making greater use of electronic records to improve patient care. He is currently leading a project to link cancer registry records on colorectal cancer to electronic primary care records.

Recently he acquired a sub-licence for a large dataset of anonymised electronic primary care records (THIN: The Health Improvement Network http://www.epic-uk.org/) and he is keen to undertake collaborative research using this resource.

Tom is a  a reviewer for many grant awarding bodies. He has been a member of the NIHR Research for Patient Benefit grant awarding committee and also was a member of the editorial board of the Health Technology Assessment journal.
