Procedures
RECRUITMENT
Physicians were recruited at each site through information sessions and individual meetings to explain procedures and complete consent documents and baseline surveys. Patient recruitment procedures were designed to enroll similar patient numbers across physicians and across patient race (i.e., stratified by physician and race). Research staff identified eligible patients by examining upcoming appointments for participating physicians. Clinic staff informed eligible patients of the study and assessed interest. Research staff met with interested patients to explain the study, obtain consent, and administer baseline surveys. Then, research staff tracked participating patients for up to 2 years to identify those who had a scheduled appointment with a participating physician and were potentially eligible for an available therapeutic clinical trial, indicating there may be a trial discussion and invitation. These identified patients were asked to participate in the randomized controlled trial. This involved completing surveys before and after clinical interactions with a participating physician, being randomized to receive the communication intervention or usual care, and having their interaction with the physician video recorded. All surveys were completed using Qualtrics© survey software. Qualtrics randomly assigned patients to either the usual care or intervention group (1:1). Patients randomized to usual care participated in all study procedures, but did not receive the communication intervention. At the end of the two‐year period, research staff examined patient medical records to determine whether patients had received an invitation to participate in a therapeutic clinical trial.
