Though I have to admit that this one is a very complex topic that I can not see could be adequately covered in a place like this.
When I first worked Medical we used Paper for everything and even though we are more secure now as the chances of a Security breach are less likely when they do happen instead of just being the one persons File that can be got it's thousands so the breaches are far more intense when they do accrue.
Personally i can understand why they have WiFi Networks in Hospitals as it's far easier to set up Coronary Care Units without the need to pull lots of Cable so that patients can be easily monitored. Of course the down side is that it's also easy to break in and do what you like to those same devices.
What I have always found amusing is how members of the General Public are asked to turn off Mobile Devices as they may interfere with the Wireless Medical Devices but that same person can be sitting in a Examination Room with a Doctor who takes Phone Calls on their Mobile while in the process of talking to them.
Here there are 2 distinct problems you are facing the ease of rolling out new devices in any part of the Hospital at virtually no expense and Security of those Devices. Even if they follow Basic Security Measures used in other industries there still is no security as the Devices themselves where never designed to have this. They where conceived to be open and easily interfaced with for speed and better Patient Outcomes but because of their current Widespread use the potential for Adverse Medical Outcomes is far higher now days.
Then there is the Administration who asks why they should have Hard Wired Devices in use in the Hospitals when it's far cheaper and easy to use WiFi Devices which means that they are not as restricted when they have the need when something breaks out.
Talk about being between a Rock and a Hard Place. But I wish you Luck with this.
