Multi-source evaluation of an educational program aimed at medical students for interviewing/taking the clinical history using standardized patients.

Simulations with standardized patients (SP) have long been used for teaching/assessing communication skills. The present study describes and evaluates an experiential training methodology aimed at medical students and based on interviews with standardized simulated patients. The training was focused on developing basic communication skills and taking medical histories. Longitudinal observational study of a cohort of third-year medical students. Three interviews with SP were carried out and videotaped. These interviews were assessed by the students, the SPs and the professors of the relevant subject areas. 83 students conducted the interviews. The self-evaluations performed by the students showed an improvement between the first and third interviews, as demonstrated by the increase of 6.7% (CI 95%=3.6-10.0%) (p<0.001) in the percentage of detected items. The SPs stated an improvement of 8.5% (CI 95%=2.9-14.1) (p=0.003) from the first to the third interview regarding the percentage of students that showed a level of interest in, and ease with, the patients' concerns. Finally, the teachers found a mean percentage of items identified in the third written clinical history of 61.4% (CI 95%=59.1-63.7) of the total available. This educational program, carried out with standardized simulated patients, showed positive signs of improvement from the first to the third interview, in both the student self-evaluations and the level of interest and ease perceived by the SPs. Additionally, the mean level of information recorded in the written medical histories was considered to be acceptable.
