“Where is most of your personal data stored? Think about it – who has the most critical, personal information about you? It’s not your bank, or your mortgage company or your Internet service provider. In fact, it’s a loosely connected network of healthcare entities: your doctor, the lab who does your tests, your local hospital and your health insurance provider.
While data mining for intelligence is a mature practice in most other industries, particularly financial services and telecom, this is not the case in healthcare. The reason is that your medical information is too spread out and inaccessible. It’s in doctors’ charts, hospital charts, paper lab results and pharmacy computer systems. “Big data” hasn’t really visited the healthcare industry in a large way.”
