Actually, that's a very disturbing article. And I wouldn't really characterize it as "lessons learned" but more like "Ooops! Let's not do that anymore..."
Seriously, it sounds like these wounded service members really were just unwitting guinea pigs for many of these "innovative," i.e. experimental, products and procedures. What really galls me is the fact that these experimental procedures were implemented service-wide as standard care with little to no clinical evidence to support it. There is a place for trying out new things, on a small scale, in combat that wouldn't be ethical to experiment with during normal situations, but that care and process seems to have been largely thrown out the window here.
It sounds like a good idea is enough to win service-wide approval in some cases. Reminds me of the same way that many investors have been duped into buying into various companies or financial investments lately by simply having a "good story" behind them. Anyway, there are so many things from that article that disturb me.
And it's a good thing to note, based on this article, that just because the Army uses something for first aid doesn't mean that it's a smart idea for you to carry it, too. Like, I had no idea that they had abandoned the new HemCon bandage until I read this article. Good to know.
