Silicon Valley hoping technology can reform labyrinthine U.S. medical system

Entrepreneurs say their technology could smooth revolutionary reforms of medical care in the US, which spends $2.6tn a year on health, or 17 per cent of gross domestic product. As policy changes roll out over the next few years, insurance companies will be forced to limit their profits, and hospitals will face penalties if patients return to the hospital within 30 days of being discharged. Doctors will no longer be paid for how many X-rays they take or laboratory tests they run but for how well their patients are doing.
