Research Programs


Olaf Cremer (1971) was trained as an anesthesiologist, intensivist and clinical epidemiologist. He has worked as a full-time staff member in the department of intensive care medicine of the UMCU since 2007. Dr. Cremer has designed and co-developed the patient data management system that is currently in use. His detailed knowledge of the system and computer programming skills allow him to explore this clinical database as a rich source of information for several research projects within the division.
Dr. Cremer obtained his PhD degree in 2005 with a doctoral thesis on goal-directed management of patients with severe traumatic brain injury. His thesis included both experimental clinical studies focused on cerebrovascular pathophysiology, as well as large cohort studies focused on patient outcomes. Since 2008 he has been studying the clinical epidemiology of infections in the ICU. To this aim, dr. Cremer is the clinical PI of the MARS (Molecular Diagnosis and Risk Stratification in Sepsis) study, an ongoing multicenter project aiming to develop and validate new technologies for early diagnosis and prognostication in sepsis. Within this study framework, he focuses on the modeling of outcomes and complications of severe sepsis with adjustment for competing risks and time-dependent covariates. He currently is (or has been) mentoring 9 PhD students.
