Apostolos Tsiachristas

PhD

Senior Researcher

Senior Researcher (part-time) at Erasmus University Rotterdam

Economic evaluation of complex health interventions

Apostolos joined HERC as a senior researcher in January 2015. His current work includes the economic evaluation of integrated care models in diabetes, dementia and other chronic conditions (Oxford CLAHRC), hospital-at-home services in geriatric care (CGA trial), strategies to increase cervical screening uptake (STRATEGIC trial), and process changes in breast cancer screening (CO-OPS trial). He is also principal investigator in a Diabetes UK funded study that translates variation in the quality of diabetes care among general practices in England to lifetime health outcomes and costs.

Prior to his current positon, Apostolos worked at the Institute for Medical Technology Assessment, Erasmus University Rotterdam. There, he was involved in observational (ZonMw-Disease management project) and cluster-RCT (RECODE trial) studies, in which he undertook the economic evaluation of several disease management programs in many different disease areas. He also investigated the cost-effectiveness of new professionals and new professional roles in integrated care in a FP7 European project (MUNROS project). Apostolos also worked as consultant at APE, a public economics consultancy located in The Hague.

Apostolos has been teaching health economics in undergraduate, postgraduate, and professional courses in Oxford and Rotterdam. His work is published in numerous international scientific journals and presented in prestigious conferences in his field. Apostolos is Editor of International Journal of Integrated Care (IJIC) and Athens Journal of Health (AJH) as well as Associate Editor of BMC-Health Services Research (BMC-HSR). He also acts as a reviewer in several journals and leads the Health Economics in Integrated Care special interest group of the International Foundation for Integrated Care (IFIC). He is also affiliated to Green Templeton College, University of Oxford.
