Seow Tien Yeo
SeowTien is a Research Fellow in Health Economics at the Centre for Health Economics and Medicines Evaluation (CHEME). She holds a BSc. (Hon.) in Food Science and Nutrition from the National University of Malaysia and a MSc. degree in Public Health and Health Promotion from Bangor University. She has twelve years research experience. Her primary research interests are economic evaluation alongside clinical randomised controlled trial and preferences of people in health care settings. She is also a staff PhD candidate exploring the health economics of EUS staging of gastro-oesophageal cancer and the current clinical practice in Wales (funded by Tenovus Cancer Care). She is multilingual – She can speak six languages (English, Mandarin, Malay, Hokkien, Cantonese and Japanese) and a bit of Welsh.
- Economic evaluation alongside randomised controlled trial

- Discrete Choice Experiment / Discrete Choice Modelling
As Co-PI / lead health economist / co-lead health economist –
- PCI-QOL study (co-PI; funded by the NIHR Research for Patient Benefit) – A cluster randomised controlled trial looking at improving quality of life through the routine use of the Patient Concerns Inventory (PCI) for head and neck cancer patients (PCI-QOL).
- WICKED study (funded by Cancer Research Wales) – The development and evaluation of primary care interventions to expedite the diagnosis of symptomatic cancer in Wales
- TOPCAT-G study (funded by BCUHB) – A feasibility study comparing nurse-led follow-up care after gynaecological cancer treatment with standard, hospital-based, medical follow-up care;
- Oral Health Pilot DCE study – A pilot discrete choice experiments (DCEs) study exploring patients’ preferences for oral healthcare service delivery and the feasibility of gaining preference of patients using DCE.
- Trismus Trial (funded by the NIHR Research for Patient Benefit) - A feasibility study examined the change in jaw opening between pre and post radiotherapy in patients with head and neck cancer using Therabite as compared with wooden spatula (standard care);
- ELCID trial (funded by the National Awareness and Early Diagnosis Initiative (NAEDI) – Research Core Funding Partners) – A feasibility study explored early lung cancer identification and diagnosis with an aim to identify whether 'extra-NICE' guidelines improve lung cancer survival as compared with current 'NICE' guideline;
- TOPCAT-P (funded by Macmillan Cancer Support) – A feasibility study comparing nurse-led holistic needs assessment care after prostate cancer treatment with standard usual care;
- EPIC trial (funded by the NIHR SDO programme) – Evidence into Practice: evaluating a child-centred intervention for diabetes medicine management;

Alongside this, she has conducted a sub-study of the DR study using a Discrete Choice Experiment (DCE) approach, to elicit patients’ preferences for different aspects of the DR screening service;
- Systematic review of effectiveness and cost-effectiveness of public interventions to promote mental well-being in people aged 65 and above, funded by NICE;
- MortISE study (funded by the Chief Scientist Office ) – Steroid injections (methylprednisolone) in the treatment of Morton's neuroma: patient-blind randomised controlled trial
- Incredible Years' follow-up study (funded by the Health Foundation) – Long-term effectiveness of a parenting intervention for children at risk of developing conduct disorders
- LILAC study (funded by WORD for Health and Social Care) – Incredible Years parent training support for foster carers in Wales: a multi-centre feasibility study.
- Orphan drugs study (funded by Actelion) – A study of drugs for exceptionally rare diseases: do they deserve special status for funding?
- Fruit project (funded by CHEME) – A costing and feasibility study to promote fruit consumption in primary school children in Anglesey, North Wales.
