Science is once again catching up with science fiction.
Without seeing the newsletter, I'm guessing that the wearable computing applications for the healthcare industry would be divided into two categories.
The biggest category would be patient applications. With the proper hardware and software, a person could be monitored 24/7 and checked in 'real' environments. If a set of problems is known in advance, the wearable computers could control an array of medicines that could be released into the bloodstream to keep the body in working order.
The expensive category would be healthcare personnel applications. Doctors, nurses and medical techs could have instantly available information about patients and potential treatments. They could also have interfaces to medical hardware that don't vary from machine to machine, even if the hardware gets upgraded.
Better yet, if properly set up, the problem of mistaken identity could be greatly reduced. Horror stories of the wrong body part being removed during an operation could be reduced to an even smaller number than actually occurs.
It will be interesting to see what the article is like.
