Participant Flow

Within each academic year, we aimed to randomize training times to 1 of 5 start dates using a stepped wedge design. However, this design was not feasible beyond the first year of our study because of the COVID emergency.

To maintain clinical staff services in the hospital, we were not able to maintain the cluster randomization of trainees. We aimed to enroll cohorts of trainees over a 3-year period, with each academic year constituting an intervention cycle, with 3 cycles of implementation corresponding to 3 sequential academic years. Due to COVID, we extended enrollment to a 4-year period. Please note - only trainee participants were considered enrolled. Patient participants were not considered 'enrolled'.

PRIMARY outcome

Timeframe: Control period is 6 months before the intervention and intervention period is up to 6 months after the intervention

Population: Blood pressure data was obtained from electronic medical records of 944 patients during the control period and 1,651 period patients during the intervention period.

Systolic and diastolic blood pressure of patients treated by the participating clinician trainees as reported in the Electronic Medical Record.

SECONDARY outcome

Timeframe: During CONSULT-BP session 2 clinician training intervention (simulated standardized patient encounter)

Population: RELATE scores were obtained from "standardized patients" (or mock patients) during interaction with the Clinician Trainees.

The RELATE (Respect, Empathize, Listen, Ask, Talk, Engage) is a 19-item checklist completed by an informant group of "standardized" patients during a simulated standardized patient encounter to evaluate interaction with the participating clinicians. The RELATE checklist contains 4 factors: Respect (4 items), Empathetic Listening (5 items); Ask and Talk (Inquiry, 6 items), and Engagement in Partnership (4 items). The checklist scores are from 0 to 38, with higher scores reflecting better communication from the perspective of the "standardized" patient.
