You obviously haven't worked in the field. It's really difficult to get anything done. You have way too many stakeholders. The government issuing rules and changing them often, the nurses wanting one thing, the doctors wanting another (often that is to do nothing), the administrators another, etc. All of this needs to be customizable to the workflows of all the different hospitals and clinics. Then you have all the different fields of medicine (you thought ambulatory care was going to be the same as an inpatient hospital?), which ads another multiplier. Then you have the software companies having to put all those requirements together, and interface with all the other software out there, and you have a huge mess. If anyone can come up with a software that satisfies all of these demands, then the lead architect deserves every award out there.
More likely you need someone like Apple coming up with the one true way and shoving down everyone's throat. You'd probably have yourself a rebelion among all the practitioners, but that's the only way to get it done.
