PROJECT NARRATIVE When Americans interact with everyday technology such as mobile applications and websites, they leave behind digital footprints that can reveal a great deal about individual health. The proposed research will define the emerging ?health-relevant digital footprint? and evaluate consumer preferences around use of information from inside and outside the health care system.

Health-relevant information no longer comes just from electronic medical records but also from the digital footprints left behind when people use mobile applications, search the internet, wear activity monitoring devices, access direct-to-consumer health care testing, or simply converse in social media. Many efforts including those tied to the Precision Medicine Initiative (PMI) are fueling the development of large population-based databases that link clinical and genetic information.
