Interruption in the medical interaction.
OBJECTIVE
To describe patterns of interruption in the physician-patient interaction; specifically, to determine who interrupts, to determine if a shift in control occurs as a result of interruption, and to characterize the information gained when patients interrupt physicians.


METHODS
Observational.


METHODS
Community-based primary care practices in North Carolina.


METHODS
Internists and family physicians in private practice in North Carolina (six men and two women) and their patients (13 men and 27 women).


METHODS
None.


METHODS
The obtainment of control of the interaction, at least momentarily, as a result of interruption.


RESULTS
Analysis of 40 audiotaped interactions revealed 833 interruptions (mean +/- SD, 20.8 +/- 12.2 per interaction): Patients initiated 55% of all interruptions. Physicians and patients each gained control of the conversation after 50% of interruptions. Patients gained control after 74% of patient-initiated interruptions, and physicians gained control after 79% of physician-initiated interruptions. Patients were more likely to gain control by interrupting late in the interaction, and 75% of patient-initiated interruptions resulted in new information (solicited and unsolicited) being contributed to the interaction.


CONCLUSIONS
Interruption by patients can be an informative event.
