From Fast Co-Exist as it relates to personal health information:
The emerging and heavily funded field of precision medicine revolves around the fact that doctors can start to personalize diagnosis and treatment based on how others—whether similar to you in their DNA, demographics, disease pattern, or life habits—respond to care. In the future, the goal is that health care will be highly personalized, and improved outcomes and lower costs will result. This is at an early stage, but already, responding to financial incentives in Obamacare, hospitals are using data mining to predict which patients are more likely to be readmitted within 90 days. People at a high risk to return are likely to receive more attentive follow-up care. At one hospital, for example, they are assigned a post discharge coordinator, where someone at a lower risk might not get the same treatment.
