Microsoft bests Google with Aetna, Yahoo beefs up through partnerships

Microsoft continues to line up HealthVault partners: the latest is Connecticut-based health insurer Aetna. Members currently using Aetna's electronic Personal Health Record feature will be able to transfer those records to Microsoft's HealthVault in November. In addition, Yahoo is bulking up its Health portal with content from HealthGrades and Waterfront Media's Everyday Health Network. HealthGrades provides hospital and physician ratings and reviews, which Yahoo will integrate into a new, searchable physician database along with related Yahoo Answers and Yahoo Group discussions.
