Mart Janssen studied Mechanical Engineering at the Technical University Eindhoven. After graduation he worked as a Mechanical engineer within the Canberra electricity and water supply (Australia) where he was introduced to reliability assessment. From 1990 to 1999 he worked as a risk & reliability engineer/consultant within the oil and gas industry, electricity supply, flood protection and transport sectors for KEMA and the UK Atomic Energy Authority, and for the Dutch Ministry of Water. After a sabbatical in 2000 he decided to change his focus to applied statistics and worked for VNU in the field of database marketing. However, enjoying the work with regards to its content, he felt out of touch with the subject matter and in 2002 started working for the Medical Technology Assessment (MTA) department on carotid artery stenting. Since 2004 he has been working solely on blood transfusion related technology and risk assessments and is currently Principal Investigator of the Transfusion Technology Assessment group, a collaboration between the Julius Center and the Sanquin Blood Supply Foundation. The TTA group is responsible for the development of models to support blood transfusion related decision making. Examples are risk models, prediction models, cost-effectiveness models. Also the TTA group is involved in various international projects and collects and analyses data on European blood use and supply for the Council of Europe.
Interests and Focus
The main interests of Mart Janssen lie in the area of applied mathematical/statistical modelling and decision making. He has a special interest in value of information analysis, expert opinion assessment, Bayesian statistics, data modelling and decision analysis. He has performed several (published and unpublished) cost-effectiveness analyses of blood screening interventions and risk assessments of blood component transfusions and plasma derived medicinal products. In the past years the TTA group has developed a national representative database of 2.4 million transfusions of Dutch blood transfusion recipients in the PROTON Study (supported by a ZonMw grant). The main recent research projects at present are: (1) the PROTON-2 / DTD study, an extension of the earlier PROTON study, which aims to construct a national blood transfusion warehouse ; (2) the BloodMatch study, in which costs and effects of various blood matching strategies and their implications for all elements within the blood transfusion chain are assessed in order to optimize of such strategies; and (3) the recently concluded MITCH study in which a generic model was developed to assess the risk from emerging infections for the blood supply.
