AHLTA is an abomination and needs to be completely ****canned, with extreme prejudice, yesterday. We've been "fixing bugs" in that steaming pile of crap for years and years and years. And it still sucks.
Essentris is a cartoonish mess that any CS undergrad who wasn't painfully and confusedly coming down off a meth binge would be ashamed to turn in for credit. Wankers couldn't even be bothered to use antialiased fonts, something Windows does for you.
As for a 5 year project ... this is actually going to get done pretty fast. 1st rollout to the lucky Pacific Northwest is supposed to be 2016 I think. DoD is throwing money, time, and people at this project like nothing I've ever seen before. Well, not counting Halliburton/KBR. One of my collaterals is as a subject matter expert, alongside dozens, if not 100+ others, split over a number of areas/domains. Unbelievable how many people are part of this, clinicians and not. There was just a huge conference in VA a few weeks ago. Commands are being ordered from up in high by the prince of darkness himself to free people from other duties to travel to these events from, well, everywhere, all funded. The amount of travel money spent 2 weeks ago for just one of these shindigs could probably have funded 90s-era CME travel for every DoD physician for a couple years.
It's going to happen, and soon. It remains to be seen how well it'll be done, but even if we wind up with crayons, tin cans, and string it'll be better than AHLTA and Essentris.
