Smeall building JS113

Prior to appointment as Foundation Professor of General Practice and Primary Care in Peninsula Medical School (Universities of Exeter and Plymouth, John was a senior clinical lecturer at King’s College London, and previously lecturer in Edinburgh.

John has led the development of Academic Primary Care in the South West Peninsula since 2002. His personal research interests focus on improving access and patient experience of Primary Care, Quality Assessment of Clinical Medicine (including an academic interest in multisource feedback within the context of revalidation of all UK doctors), Cardiovascular Risk Assessment and mitigation, in particular with studies focussing on inter-arm difference in blood pressure and early Diabetes, and provision of mental health care for patients in Primary care settings.

John leads the department, providing leadership to a team of around 45 people. John has national academic roles in respect of the UK National Institute of Health Research Trainees Coordinating Centre (member of Doctoral Awards Panel), UK National Institute of Health Research Health Services and Delivery Research Board (member), the South West Regional Advisory Committee on Clinical Excellence Awards for Senior Doctors, and Chair, UK Heads of Departments Group (Society for Academic Primary Care). John is a fellow of the Royal College of General Practitioners, and obtained his doctorate in 1998 (MD) ‘The Accessibility of UK Primary Medical Care: Problems, Practice and Potential’. He has published around 230 papers in major academic journals.

Broad Research Specialisms

Access,Quality, Primary Care, Patient Experience.

John is currently chief investigator on a NIHR (HS&DR) funded study examining issues relating to the recruitment and retention of GPs - the ReGROUP study.

John recently jointly-led a UK NIHR funded programme on improving patient experience in Primary Care, undertaken in conjunction with Professor Martin Roland (University of Cambridge Centre for Health Services Research). Much of that work focuses on the utility of the English General Practice Patient Survey, the largest routine survey of Primary Care undertaken in the world. John was involved in the design of the study, and continues to advise both Ipsos Mori and the UK Department of Health on the roll-out and implications of the findings.

John led research providing evidence around the use of multi-source feedback (360⁰ Appraisal) for the UK General Medical Council. UK doctors are subject to an ongoing process of revalidation (since 2012) and research led by John Campbell has informed the design and delivery of the related processes.

John has important ongoing work undertaken in conjunction withDr Chris Clark examining the potential role of an inter-arm difference in blood pressure as a possible marker of early vascular disease.

Finally, John has undertaken research into the diagnosis and management of depression in Primary Care settings, identifying the lack of added effect of exercise beyond the provision of routine primary care, and providing important evidence in respect of the role of cognitive behavioural therapy for patients who have proved to be resistant to treatment for depression.
