I would definitely pursue the healthcare field if I were you. It's such a hot field to be in coz there are lots of jobs out there!
I'm a healthcare IT consultant. I had no prior healthcare knowledge, background, or degree. I'm a programmer so really I just had to learn the system. As you said most hospitals (and even clinics) are moving away from paper medical records and putting in an EMR system. This is a huge and good project to be involved in! I won't lie, there's a lot of hard work involved and you have to be certified, but it keeps you committed and you learn a lot. At least it kept me committed until we got thru the implementation phase. Once that finished, I moved to a new hospital still doing the same thing and went thru that implementation too. Then I decided to go into consulting doing the exact same thing only paid better. Plus I get to work from home (this isn't very common among all consultants but because of the nature of my work, I can do it).
There are lots of areas you can get involved in with the project if you chose to do it. Or if you don't but you feel like you've got the expertise, you can get into that role as well (they're called Subject Matter Experts). The hottest jobs right now are in the area of 'build analysts'.
Anyway, I definitely think it's a good field to be in. I've been doing this for 7 years now and I love it!
Here's a sample of some of the jobs out there related to this:
