Look what you Gain
Last weekend, I had to make a trip to the emergency room. It could be that the system they use in the hospital system that I use for my health care is a very good one, but even the super-stressed, super-busy ER docs had no trouble using the system and entering the complex results of my visit into it. I was scheduled for a follow-up with a specialist the next day. Instead of the specialists having to listen to my unprofessional explanations, they had instant access to what the ER docs observed, without being filtered through me. My Primary Care doc also has instant, unfettered access to both the specialist's and the ER's notes. The system also maintains a patient's center, where I got a virtual reading assignment of articles about my condition, suitable for non-medical people.
The biggest downside is that the system cannot communicate with the systems maintained by other doc's or medical organizations. We should all look forward to the day when these systems are far enough along for standardizations to be first agreed on and then enforced.
