This document discusses health record banks as a potential solution for collecting and sharing patient health information. It explains that big data has value if there is a large, comprehensive set of electronic patient records in a central repository. However, funding health information infrastructure through taxes is unpopular and relying on potential healthcare savings is difficult. Health record banks could provide a sustainable business model by generating revenue from stakeholders while giving patients control over their data and prioritizing privacy. The model shows potential for health record banks to be profitable without requiring captured healthcare savings.
