Evidence-based medicine (EBM) was making healthcare decisions based on the results of clinical trials with a limited number of subjects and a limited number of data points (e.g. 400 patients with diabetes taking a medication and having their blood sugar measured three times daily for six months = 216,000 data points).  BDM is the healthcare decision making that will evolve out of population level trials with massive numbers of data points (e.g. 50,000 diabetics taking a medication and having their blood sugars continuously monitored using impantable sensors = BILLIONS OF DATA POINTS).  But BDM will also be tailoring an individual diabetic's treatment based on continuously monitoring their blood sugar using an implantable sensor, analyzing the data in the context of their genomic data and their entire medical and family history.

IBM is making a three-year $100M bet that they (not the traditional medical research establishment) have the knowledge and technology to make BDM a reality.
