• Some physicians waited only 3 seconds before interrupting the patient
• Doctors were more likely to interrupt if the patient was a woman than if it was a man
• Male doctors were more likely to interrupt than their female counterparts
• 2% of patients resume their story after being interrupted.
• When interviewed after a doctor patient encounter, doctors and patients did not agree on what the encounter was about
