Professor John Marriott is Professor of Clinical Pharmacy.

John Marriott led the Pharmacy developments within the College of Medical and Dental Sciences. He is a practising pharmacist in the UK, registered with the General Pharmaceutical Council.

John has active research groups examining a variety of aspects of clinical pharmacy and therapeutics and has published widely in scientific journals and book chapters. He has major grants from the SHA and other funders to support this work. He is highly motivated to develop and evaluate the impact of Pharmacy in multi-professional healthcare delivery and is an enthusiastic Pharmacy teacher, keen to develop and use new learning technology and methods for the benefit of students and professionals. The national and international impact of multi-disciplinary education in prescribing is evident from the HEE-sponsored SCRIPT project, for which he is the principal investigator.

He has professional roles in the wider UK, being a member of the Royal Pharmaceutical Society of Great Britain Assembly, and the Formulary Committee of the British National Formulary (and the Joint BNF Committee): he is also the Chair of a major HRA Ethics Committee in the West Midlands.

John Marriott gained a BSc (Hons) in Pharmacy from Aston Pharmacy School in 1979. After completing a pre-registration post with Boots the Chemists he registered as a Pharmaceutical Chemist in 1980 and worked extensively in the community sector for a range of independent and multiple Pharmacy contractors. Significant professional experience was gained within the NHS hospital sector holding a variety of appointments up to Chief Pharmacist level in a large district and general teaching Trust. He was a registered pre-registration pharmacist tutor in this role.

He has significant experience of scientific research, completing a PhD in experimental vascular pharmacology at Aston University and he also held a British Heart Foundation Fellowship at Birmingham Medical School examining the effects of hypoxia on vascular muscle contractility.

After leaving the NHS he joined the academic staff of Aston Pharmacy School as a lecturer, senior lecturer and then Professor of Clinical Pharmacy in 2008. He also held the posts of Director of Postgraduate Programmes and Head of the School during this period and was the Chair of the University Ethics Committee.

Research Themes

  • Paediatric medicines use
  • Barriers to novel medicines development (in paediatrics)
  • Predicting and evaluating medicines adherence
  • Risk in pharmaceutical systems
  • Optimisation of antibiotics use
  • Toolkits to optimise prescribing
  • Drug allergy labelling

Research Activity

Measures to identify and improve poor medicines adherence. Research themes in partnership with pharmaceutical industry are evaluating the relationship between patient mood cycles and medicines adherence with an intention to optimise therapeutic outcomes. The research aims to test and understand which patients are likely to respond to medications with the aim to equip the Healthcare professionals with appropriate information not only to provide their duty of ensuring patients take their medication as agreed to obtain optimal benefit but also to ensure they are able to make educated recommendations on which therapy would be appropriate for certain patient subgroups depending on their mood profile types. 

Prescribing indicators. Various indicators are used commonly to evaluate and quantify prescribing in primary care. Surprisingly there are no recognized, uniform measures of prescribing in NHS secondary care. This research theme is examining the development and validation of effective prescribing indicators for use in hospitals.

Optimising antibiotic usage. Antibiotic usage is being examined as a key therapeutic intervention with problems associated with prescribing in order to model prescribing indicator development and devise medicines optimisation strategies.

Controlling medicines waste. There is crude evidence that wastage of pharmaceuticals is commonplace. This research strand is designed to quantify precisely the amount, types and reasons why medicines are not used. The theme also explores patient and prescriber attitudes towards wasted pharmaceuticals.

Optimising prescribing through education. SCRIPT HEE Prescribing Project - ( John leads the project funded by HEE to develop and implement an electronic prescribing education toolkit for F1 prescribers – the project has extended to the range of prescribers in healthcare. The project has developed and is evaluating the impact of modules developed in an interactive electronic web based format to improve the competency of prescribing. The evaluation and scope of the on-line learning is continuing.

Paediatric Medicines Management across the hospital-primary care interface. The nature and types of interaction between an NHS specialist paediatric care healthcare provider and the processes and systems involved in managing medicines in other healthcare sectors (principally NHS secondary and primary care) are being investigated.

Drug allergy labelling and de-labelling in the UK and globally. Methods to accurately label and de-label drug allergies are being investigated locally, nationally and globally.
