The cover for this Summer’s newsletter of the Centre for Health Economics and Medicines Evaluation features PHERG, the Public Health and Prevention Economics Research Group, led by Professor Rhiannon Tudor Edwards, with members pictured above.

Rhiannon was named amongst a list of most important authors in health economics in a recent global bibliometric analysis of articles referring to health economics and published between 1975 and 2022 (Drummond, Jonsson, Coast, Donaldson, and Edwards). She was named among the top 5 most important health economists, and among the top 10 in terms of productivity. PHERG’s research contributed to Bangor University being named amongst the top 10 most collaborative higher education institutions in health economics out of 1,723 institutions worldwide (see figure below).

Wales Active TraveL ReseArch ConSortium (ATLAS)

Dr Emily Holmes, Senior Research Fellow at CHEME, is one of seven founding members of the “Wales Active TraveL ReseArch ConSortium (ATLAS)”. The Consortium aims to deliver a programme of research to support the modal shift towards active travel in Wales, for all. Our research considers the impact of active travel on 3 key interconnecting areas: health and wellbeing, environmental health and politics, and accessible Welsh landscapes.

Value of information and cost-effectiveness of screening for developmental dysplasia of the hip (VOICES-DDH)

Dr Catrin Plumpton, Lecturer in Pharmacoeconomics at CHEME, is Chief Investigator of VOICES-DDH. Developmental dysplasia of the hip (DDH) affects between 1 and 10 in 1,000 live births in the UK.
Detected early, DDH can be treated without surgical intervention, however late detections require surgery and are associated with poorer prognosis. In England and Wales hips are screened in newborn babies and again at 6-weeks, however the number of late detections remains high. Alternative screening programmes may reduce late detections and would also increase the number of hips treated, some of which may resolve naturally without treatment. The study will develop a decision analytic model and conduct a value of information analysis.

Medicines-related Teaching and Research

Dyfrig Hughes has led a working group within Bangor University to develop degree courses relating to medicines and prescribing. These include the initial steps towards accrediting an MPharm pharmacy
degree, a BSc degree in Pharmacology (first intake in September 2023), and a postgraduate module for healthcare professionals in Pharmacogenomics. These courses represent a new direction in the
development of Bangor University’s medical and health-related teaching programmes, and bring opportunities for research concerning the safe, effective, and efficient use of medicines.

Antipodean collaborations

Research concerning medication adherence has led to Dyfrig Hughes collaborating with Dr Dan Wright and PhD student Klarissa Sinnappah at the University of Otago on developing tools to assess the risk of bias in adherence research; and with Dr Sophie Stocker and PhD student Toni Michael, University of Sydney on interventions to improve adherence to treatments for gout. An economic evaluation of the intervention is planned, to establish whether patient-centred point of care monitoring of urate, with feedback, can improve adherence to allopurinol.


Welsh Crucible 2023

Dr Llinos Haf Spencer was selected to be a part of the Welsh Crucible 2023, which is a Professional Development platform for Future Research Leaders in Wales. Llinos said “It was a pleasure to meet the other Cruciblees and to share ideas and make important connections. I learnt about policy, the media and a lot more! The facilitator Vivienne Parry is an expert in linking ideas and people, and it was great to meet with Professor Catherine Green OBE, an Associate Professor in Chromosome Dynamics, University of Oxford who was involved in the development of the Oxford-AstraZeneca Covid-19 vaccine.”

Welcoming the development of Rural Health Economics at Aberystwyth University

Rhiannon Tudor Edwards and Professor Deb Fitzsimmons met up with Professor Murray Smith, newly appointed Professor of Rural Health Economics at Aberystwyth University. This post has been funded jointly by Aberystwyth University, Hywel Dda University Health Board and Betsi Cadwaladr University Health Board.

Citizens Advice on Prescription project – funded by NIHR

Rachel Granger and Rhiannon Tudor Edwards visited Citizens Advice in Speke, Liverpool to experience how data are being collected for the Citizens Advice on prescription project. With partners at the University of Liverpool, we are exploring the cost effectiveness of this programme that enables GPs right across Liverpool to refer patients to Citizens Advice for support and signposting to services such as debt
counselling, domestic violence support, addiction services and social prescribing. A specialised service for new mothers provides tailored support through the perinatal programme. This is an example of an economic evaluation of a complex intervention within a complex system.

Invest for health - Horizon Europe Project

Dr Holly Whiteley and Rhiannon Tudor Edwards attended the kick-off meeting of the Invest for Health project funded by Horizon Europe in Malmö, Sweden in February. This four year study brings together partners from across eight European countries to explore “Smart Capacitating Investment” in prevention to improve population health.

About People


Dr Huw Lloyd-Williams has been awarded his PhD. His PhD focussed on the economics of adverse childhood experiences (ACEs) and how these affect social mobility.

Dr Bethany Fern Anthony, a Research Officer at CHEME, has been awarded her PhD. Bethany’s PhD thesis investigated the provision of general medical services by non-medical health professionals and allied health professionals. Bethany’s thesis included two systematic reviews, a national survey, and a mixed methods study (comprising of a budget impact analysis and qualitative interviews) to explore role substitution in primary care.

Au revoir to Dr Pippa Anderson who contributed to the Pharmaceutical Economics, Policy and Prescribing Research Group within CHEME; and to Dr Blanca Guizar Moran who leaves Bangor having supported Pippa on a project on the specialist commissioning of genomic services in Wales. We wish them both well in their future endeavours.
