Just curious, how old are these frozen-in-fear-at-the-computer nurses? Maybe because my dad (67 yrs old) has always been a techie that I'm picturing frail 90 yr olds; my dad actually built our first home computer when I was in...1st grade I think? But when I read about these "older" nurses having so much trouble, I think of in "Hidden Figures," where the term "computer" referred to the people who did the calculations. Then as the story progresses, Octavia Johnson's character in trying to stay ahead of the time, gets into programming the actual IBM computers.
We aren't living in a time of technology being that completely new. Do they use email -- even just employee email? Shop online? Navigate without the use of paper maps or the stars? If so, I wouldn't think an EHR would be such a roadblock.
That's not to say that their *perception* doesn't tell them it's difficult. I like your swimming analogy. I hail from rural Wisconsin, and as a kid took swimming lessons on a lake in June. I remember once when I was 12, seeing the other kids' teeth chattering and lips turning blue. After getting home, out of curiosity I checked my temp -- it was around 95°. The water was cold! Getting back to your point, had we been at the lake with our family and tiptoed into the water, it was NOT going to happen. Each step out from the shore would expose more skin to the cold water. However our instructor had us duck under the water first thing. Initially it was very uncomfortable, but then it was tolerable -- at least until hypothermia started setting in.
A new EHR can be intimidating, BUT if they have the cognitive ability to practice nursing (which as another poster also said, has changed in recent decades in MANY ways other than computers), they have the cognitive ability to learn an EHR. They need to purge that thought that tells them their age is a barrier, and jump into that water.
