In the note about the discontinuation, Microsoft officials described HealthVault Insights as "a research project... with the goal of helping patients generate new insights about their health." Sounds like that is right in Microsoft's analytics/health/machine learning wheelhouse.
There's no explanation for the reasons behind the decision. Microsoft plans to enable those who used HealthVault Insights -- which it launched last February -- to access their data via the HealthVault website. Microsoft officials also said in the note that the company is "now applying that knowledge (from the HealthVault Insights project) to other projects."
Healthcare NExT projects, run by the company's AI + Research Group, remain a big focus for the company. Microsoft officials have said HealthCare NExT's mission is to provide personal health and wellness information to make healthcare "more proactive and holistic."
