The problems are aversion to technology in places, unwillingness to adopt new (human) protocol/processes, entrenched proprietary technology, that does not adhere to standardized formats.
Say you want to save a report for a patient for the next shift. That report needs to enter a computer system. If there is a system for that, it will most likely be a very expensive overpriced proprietary solution with expensive support contract, instead of something that has an open and intelligent format, that could be read by simply any software. The companies behind the tools will paint themselves as "specialists" for medical technology and do everything to dig a moat, at the cost of lives and they will avoid standards, as that will make their overpriced solution replaceable.
