One other feature I like about having all my data locally (on an onsite PC or server) is that it is about all the power I wield these days as an internist. The power to share or not share any of my data with anyone I choose. Will a provider still have that power with SaaS?
I agree totally. The question should be, do you really, REALLY trust someone else to hold your data for you? What if you have a bad couple of months, and fall behind in your subscription payment; what then? What if AC goes bankrupt or for some reason is shut down without warning? Unless your practice is 100% acute care, you would be dead in the water.
Dependence of electronics for medical record keeping is scary. Letting someone else hold my data is terrifying.
