I recall hearing a discussion on the radio from a medical administrator re: the rate autopsies. IIRC the rate of autopsies has dropped dramatically in past few decades. There are many short-term administrative, financial & legal reasons to skip an autopsy, but it seems like a bad trend. While it's not ethical to A/B test human medical treatment in regular care, autopsies would seems like a critical data source to make improvements in health care - seems like yet another variant of "tragedy of the commons" problem that the rates are systematically declining.
