Such is the way of progress in America. We made quick progress in military medicine in Vietnam. Then we sat on out hands for thirty years. When we went to war we were shocked to find out we didn't have many doctors who were up to date and that we had lost a lot of the edge.

Going into Desert Storm there was push to catch up for lost time and to leapfrog forward. So the gates were opened to methods and products that hadn't been rigorously researched.

So now the pendulum swings the other way. The rush to push new things has faded and people area asking important questions that got lost. Questions about efficacy, efficiency and costs. As is typical the majority of what came in new and promising has been shown to be no better, or only marginally better, than what we had. There may be a few methods and materials that are shown to be truly useful but they will typically be few and far between.
