Question for your, are you contemplating going into Nursing Informatics or a more technical type role?
I've been in Nursing Informatics since 2001. I have times of minimal contact and times of lots of contact with other people. The days of minimal contact are rare and far in between. I've been a nurse for 40 years this year. I worked 27 of them at the bedside. I currently work primarily with CPOE and part of the time assist with Pharmacy application. I have to say interaction is quite important in our job. We educate, we test, we plan, we use our nursing knowledge every day. We discuss work flow, discuss issues, help end users, discuss and bounce ideas off our co-workers and other people using the same applications you do. I love to build. That is my forte. I like to teach and can do a good job at it. I am fortunate that I was able to get into this profession without a degree and have worked at two facilities. I work on the hospital side. The ambulatory nurses working with the EHR are constantly busy with the same roles interactions as above. The end users are our customers and we need to be responsive to them. Be it building, helping, logging issues, educating....what ever is needed.
Now if you plan on going to a technical type job writing code etc, you could probably have minimal interaction, however there are always meetings, planning sessions, testing, re writes etc,, what little I know of it!
I wish you luck in finding what you are looking for. Nursing Informatics in a hospital setting is full of interactions. Some people love it, some hate it. One thought I just had, if you know a particular system very well you could possibly do some of their build from your home. Just a thought that I don't know much about. Again, good luck!
