A randomized study of feedback on student write-ups using an electronic portfolio.

Traditional methods allowing medical students and residents to review their work and receive feedback are lacking. We developed a web-based portfolio system that collects all clinical documentation and allows teachers to give feedback electronically. In a randomized control trial, we found that this system significantly increased feedback to students, often exceeding clerkship expectations. Seventy-five percent of students found the system a "valuable teaching tool". Students in control and portfolio groups agreed that the system increased feedback.
