Google is working with the American Medical Association, a US physician lobby group, to agree on a challenge plan to enable start-ups to come up with "the best new ideas for promoting data sharing in health monitoring devices". The ultimate challenge will be a mobile app or wearable device, the American Medical Association said on Monday.

Both make it easier for people with chronic diseases to share data with doctors.

"the award-winning work will show how the applicant can improve the clinical effectiveness of the doctor's work flow and reduce the cost of the health care system through the patient's health data," the statement said. "

In order to get a piece of the $3 trillion healthcare market, some tech giants have shown a growing interest in cross-border collaboration between companies in the healthcare industry to promote innovation.

Last year, Amazon and Merck launched an innovative challenge program to encourage Alexa developers to come up with new "skills" to help diabetics who are treated at home and in hospitals.

Amazon didn't say much about its intentions, but CNBC reported in March on its next ambitious goal: to develop its technology for the elderly. Compared with the young, the elderly are more likely to suffer from chronic diseases such as diabetes.

Alphabet chose to focus this challenge on the interoperability of medical data. The goal is to make it easier for patients and providers to share data such as laboratory results or medical imaging in a computer-readable format rather than PDF format. Historically, many hospitals and their technology suppliers have preferred to "lock" patients to their exclusive devices rather than providing patients with convenient data access.

It is worth mentioning that Apple is also using its medical records products to solve this problem.

The "Google-American Medical Association" challenge will eventually produce three of the best ideas to share the $50,000 Google cloud prize.
