This a very interesting post about some facts of the drivers of changing healthcare. The impact of information and communication is measurable. However the measurements are often related to coarse grained concepts like healthcare costs. Information in the role of a therapeutical intervention or in the role of a framework for a changing society needs other measures. Value oriented measurements are not available short term. The development of apropriate methods to measure outcome in a long termin is just not availabale. However it it seems intuitive to see the relationship between the documented difficulty of understanding health related information and the difficulty to follow medical advice. We tend to build causal relationships between documented facts.This may not be the best option. But there is a lot more research needed to identify relationships between the facts that may support a positive influence on health literacy and outcome. Enjoy the graphics.
