When President Obama signed the Patient Protection and Affordable Care Act (ACA) into law in 2010, one of its core tenets was expanding use and access to health technology, both by health care providers and consumers. The ACA passed at a time when the health software, app development, and mobile device industries were poised for exponential growth. In 2010, only about 20 percent of smartphone users used their device to research health information, and the number of health apps on the market was fewer than 15,000. By December 2014, health and fitness apps were the fastest growing category, and more than 100,000 mobile health apps were available. According to PricewaterhouseCoopers, one in five Americans owns a wearable health and fitness device, such as a Fitbit, and one in 10 wears the device daily. Plus, two in three health care providers are using a smartphone or tablet in the daily patient care routine. A question remains, however: How will health technology be regulated?
