Digital Health and AI

Definition. Big data refers to datasets whose volume, velocity and variety exceed the capacity of conventional data management and analysis tools.

Explanation

The term is usually defined by the three Vs of volume, velocity and variety, with veracity and value often added. In health care, sources include electronic records, claims, registries, imaging, genomics, wearables and social media.

Raghupathi and Raghupathi (2014) describe the promise of big data analytics for population health, prediction and operational management. The main difficulties are data quality, linkage, governance and privacy, and the risk that large but biased datasets produce confident but wrong conclusions.
