Innovation in medicine doesn't always mean coming up with a new device or drug.
It can simply mean different ways of doing things, even if they aren't brand new.
The current issue of JAMA is devoted to "Innovations in Health Care Delivery," and one aspect caught the attention of Dr. Jon Hallberg, a physician in family medicine at the University of Minnesota and the regular medical analyst on All Things Considered.
That piece, titled "Delivery Models for High-Risk Older Patients: Back to the Future" talks about a new idea that isn't really new.
He talked with MPR News host Tom Crann about that article and exactly what innovation in medicine means today.
