Health data science covers essentially all aspects of science where data is analysed in order to benefit human health. These data include, among other, biomedical and clinical research data from patients (e.g. molecular and imaging data), clinical data from hospitals and other health care or population registers (Real-World Data), and different ways of monitoring self and well-being, such as data from smart consumer devices.
Health data science encompasses, among other, combining and harmonising data from multiple sources. It also encompasses generating, testing and validating algorithms for different purposes, such as data modeling, data analysis, diagnosis, or facilitating decision making in health care.
The domain of health data science can gradually enable predicting diseases before onset through identifying risk factors and biomarkers in populations, preventing diseases before onset through identifying required changes, and finding optimal personalised treatments.
