System A: The Research Coordinator (RC) was responsible for contacting and consenting physicians as well as ensuring completion of study materials. System B: A system physician champion helped the RC make first contact with physician subjects. The RC was then responsible for contacting and consenting physicians and ensuring completion of study materials. System C: The system physician champion selected a lead physician at each clinic. This person worked with the RC for contacting and consenting physicians as well as ensuring completion of study materials. System D: The system physician champion was responsible for all contact with the physician participants. The RC was not permitted to contact physician participants directly. Data for time from first contact to consent and number of contacts before consent were not available for System D.
↵* Significant differences were observed between all three groups for number of contacts before consent.
