Posted also in the media thread, but Dr. Lisa Sanders, the doctor and NYTimes writer of the "Diagnosis" column was interviewed on
NPR's Fresh Air about her new book on problems with diagnosis. It's all kind of interesting (lots of tidbits on how people get it wrong, including one anecdote in which a doctor trying to be kind to a patient ended up setting himself up to miss an easy diagnosis) and minutes 12-16 deal more with her interactions with the show, how she consults with the writers, etc.
She also said that the moment in "The Itch" in which the patient catches on fire during abdominal surgery was inspired by a real life explosion due to internal gasses at her own hospital.
