Of course healthcare EMR vendors will be developing Windows 8 front-ends to their systems throughout this year and especially next, and I don't envy their job. Certain ways of using EMRs will have to change, just as they have with iPad versions of those systems. This complicates training, as it won't be practical or even necessarily possible for a healthcare provider to suddenly swap out desktop and laptop deployments for touch-based ones. The new user interfaces look promising, but they are a radical rethink.
In a year when so many providers will be struggling to complete their first year of Meaningful Use implementation, those Windows 8 systems trickling in will seem like a very unwelcome annoyance. But some of those Windows 8 users are bound to be in executive suites. Good luck convincing your Windows-loving CEO that he can't have his Windows anymore or that his executive dashboard can't be made to work with Windows 8.
I should say here that Microsoft is to be commended for trying to modernize the Windows user interface. The company just picked the absolute worst time to do it as far as healthcare is concerned. But with the continuing revolutions in healthcare tech, maybe there would never be a best time.
