hello anarchy! (funny nick)
Quick answer to your questions:
1. Are you currently using an EMR in your unit? Because the first place to start is in your own unit, with the software you're currently using. Get involved with implementations/upgrades, help out training the new nurses on the software, etc. And obviously, applied to vendor jobs. Many of them require no experience and are willing to train you.
2. If by tech skills you mean software skills, sure, skills help, but you should also be aware that I've worked with many nurses in the informatics fields who had no software skills prior to getting the job. In short, you seem to have the same background I had before I went into the field so you should be fine.
3. I would say you would enjoy the 'analysts' position. Typically these are the people who know the software and they configuring it, implement it, training others to use it, troubleshoot problems, etc.
And just fyi, I also started as a nurse, but on the side I used to do my own computer builds, repairs, helped others with their pcs, software issues, etc, and once I got sick of nursing, I decided to get a computer science degree. At the time I didn't know about informatics and I could have most likely gotten a job without spending the extra money in the CS degree, but I was so sick of the field my plan was to completely get out of it.
