The current use of e-health tools and services within the health care industry – including the adoption of electronic health records (EHRs) by physicians and hospitals, the development of electronic health information exchange (HIE) networks, and the maturation of the telemedicine market – clearly contributed positively to the quality of, and access to health care services for individuals affected by Hurricane Harvey.  While the adoption of some of these tools and services is being driven by a combination of strong market forces and public policy, electronic HIE networks have not consistently identified sustainable business models despite their benefits.  Electronic HIE networks should be considered a critical part of a state’s and region’s emergency preparedness and response infrastructure, and should receive corresponding public financial support.
