Our unit uses computer charting, and they have for quite a while. When I first started there, it was an ancient system--they don't even make repair parts for it anymore! So about 8 months ago we switched to a newer system, an expanded version of the system we used for orders (xrays, labs, etc). There was a lot of resistance at first, especially from the older nurses who aren't computer savvy. I personally love it! You can get very detailed but it's so quick! I don't know the complete name for it, we call it C2K. It has different sections, mainly v/s, treatments, assess, restraints, and education. It has a basic amount of stuff that's loaded, and you can add in a ton of things, from skin assessments to detailed neuro assessments. Once the component is selected, it then gives you options to select at whatever time is selected. (ie it pulls up a list. for example component lung sounds left, options:clear, course, rales, course rales, rhonchi, crackles...) I'm on the committee for bringing a computerized system housewide (only CCU and extended care currently use it), and I've seen some of the newest options out there. They're amazing!
The biggest obstacle to computerized charting is people. Some of our doctors have flat out refused to use it, and demand that we daily print all labs/vital signs trends/i&o out and put on chart, even when the nurse stands there and pulls everything up on command. As mentioned before, lack of knowledge about computers can hinder change. For most of these systems "hunt and peck" typers might have a problem. It's amazing how many people really can't do simple things with computers, and the learning curve can be really slow.
I love computer charting. It takes me 5 minutes to document a complete and detailed assessment, I spend a lot less on pens, my hand doesn't hurt, and I personally feel it is a safer option (in a CYA aspect).
