Research Group Siegerink

Bob Siegerink is the head of the research group Clinical Epidemiology and Health Services Research In Stroke (CEHRIS) at the CSB. Together with his group he works on several projects aimed to unravel the causes as well as the short- and long-term consequences of stroke. Additionally, he provides methodological support to researchers from other research groups of the CSB, both clinical and preclinical. Besides his work in vascular neurology, he has a strong interest in causal inference and scientific integrity, which resulted in several scientific projects, courses and collaborations.

Stroke is a complex disease that can have a large impact on an individual. To understand how we can minimize this impact, or perhaps even prevent its occurrence, a thorough understanding of the causes of stroke is pivotal. By understanding what mechanisms lead to a stroke, we open up new doors for treatment and prevention. I worked on several projects that show that ischemic stroke is, at least in part, caused by an increased clotting potential of an individual. Perhaps such a hypercoagulable state is a good target for the prevention of ischemic stroke and related diseases? But more knowledge on the causes of stroke will lead to an immediate change in the daily practice on how to take care of stroke patients. To do so, we also need to understand what the consequences of the stroke are. For example, which stroke patients have the highest risk of a second stroke, and how can we identify the patients that are likely to receive suboptimal care?

Methodology Research
Our team helps other research groups at the CSB to properly design and analyze their studies. Through their questions we sometimes stumble upon new methods and statistics that might be useful in stroke research. New research projects, where we combine knowledge from clinical and pre-clinical sciences are the results.

Stroke is a leading cause of death and disability. However, improving diagnostics and treatments such as thrombolysis and endovascular therapy have substantially reduced the burden of this disease. The B-SPATIAL register (Berlin – Specific acute therapy in ischemic or haemorrhagic stroke with long term follow–up) captures the processes during acute care of stroke patients and is a unique opportunity to assess their effects on functional outcome. Patients will be contacted via telephone three months after the event.

The research group participates in regular seminars within the CSB as well as external ones, given by cooperation partners.

Members of the CEHRiS team regularly coordinate the module “Clinical Epidemiology and Health Service Research” and teach in the module “Basics in Biostatistics and Clinical Epidemiology” of the Postgraduate Master Program Master of Science (MSc) in Cerebrovascular Medicine.

In addition to this, the research group offers thematically relevant teaching courses. The exact dates and location of the courses are to be announced. The research group is also responsible for hosting and training awardees of the CSB-Virchow Scholarship.

Methodological Consultancy

We are currently working on some documents to facilitate and ameliorate our methodological consultancy service. In the meantime, all questions with regard to epidemiology, methodology and statistics should be sent to the team leader, Bob Siegerink.
