Microsoft has created a US$ 3 million fund to invest in applications built for its HealthVault electronic medical records platform, the company announced recently. Launched in October, HealthVault is intended to allow people to access their medical records through any device, regardless of the health care provider or insurer. Recently Google too announced a trial with Cleveland Clinic in which potentially thousands of patients will be able to access their health records through their Google accounts. Microsoft’s aim with the US$ 3 million fund is to create an ecosystem around its HealthVault initiative, much like its Windows platform attracts developers to create programs that run on that operating system. In particular, Microsoft is interested in applications related to preventive care, acute care diagnosis and treatment, management of juvenile diseases, women’s health, and community and social health applications. Microsoft, which last week decided to share details of its technology with open-source programmers, also is hosting a HealthVault open-source project to make development for the platform easier.
