Around the world. We don't want to make IPT a political football, as it is a serious medical innovation that looks very promising, could be adopted very quickly, and needs a lot of research. But in a way, it can't help but become a political concern, requiring political awareness and support. We are in a sensitive window of time in which IPT is just a seed. It is very small at the moment.
Few people know about it.
Few patients have experienced it. Few doctors know how to practice it, or even know it exists. There are also a few special interest groups who could face short-term losses if IPT succeeds, and who might seek to delay or prevent such an outcome. At the same time, the huge mass of humanity, along with other special interest groups, would benefit tremendously if IPT proves valid. And much of the research, when it is funded, will be funded by the US federal government, probably through the National Institutes of Health, which cannot help but be sensitive to political influences.
