Clinical epidemiology

From data to value; value for patients and value for population health – that is clinical epidemiology. It provides quantitative knowledge about the effects of medical interventions and the diagnosis, etiology, and prognosis of disease.

Van der Bom is committed to quantifying the effects (intended and unintended) of transfusions. If a patient suffers from a deficiency of one or more components of her/his blood this component - seperated from the blood of a donor – can be transfused into a blood vessel of the patient. Despite centuries of experience and improvement of transfusions, the vast majority of transfusions is based on physiological principles rather than quantitative knowledge about its effects. Thanks to progress in the field of technology and the ambitions of healthcare to quantify value for patients it is now increasingly realistic to predict for each patient whether the intended effects of transfusion outweigh the unintended effects. Van der Bom’s research helps to optimize value for patients with hemophilia, women with major obstetric hemorrhage, critically ill adult and neonatal patients and patients with hematological malignancies. 

This research contributes to NWA questions about personalized medicine, big data, machine learning and value-based medicine.
