Well done radio feature (just a quick 5 minute listen) on Dr. Jeffrey Brenner, a Mac Arthur Genius award winner who thanks that following the "super-utilizers" of the healthcare system - making home visits, attending appointments with them - will lead to health benefits and cost savings. He's putting his hypothesis to the test by running a randomized controlled trial - tackling the challenge of matching the standard scientific methods (the RCT) to the messy, complicated reality of real human lives. Life in the real word is vastly differently from the careful, regulated world of the lab but a solid effort here to use data instead of clout and reputation to take a step forward in public health policy.
