E-Health, Privacy, and Security LawAvailable on Bloomberg Law. The world of e-health, including Internet health services, electronic health records (EHR), wireless- and Bluetooth-enabled devices, health information and services provided through smart phones and tablets, and other health information technology, continues to experience unprecedented expansion to what has become a $76.7 billion market. This expansion, spurred in part by the federal government's incentives tied to “meaningful use” of EHR technology, and perhaps in greater part by significant innovation in the private sector and consumer demand, particularly in the area of mobile health (mhealth), has come with new regulations and legal challenges. Keeping up-to-date can be a tremendous challenge for anyone working in this area. With these significant changes, and aggressive enforcement actions by the Department of Health and Human Services on the rise, health lawyers and others who work with the electronic transmission of health information need to be well informed about the current legal climate now more than ever. For that reason, it is essential to have a reference guide, such as E-Health, Privacy, and Security Law, to keep abreast of these changes.
