What health care works?

The lede:

Buried in clinical guidelines and buffeted by the latest published research findings, what’s a physician to do when faced with a patient and a 15-minute treatment window? Begin to sort through the conflicting guidelines or analyze the latest research studies?

The whole shebang.
