Urology Residents' Experience With Simulation: Initial Evaluation of MRI/US Fusion Biopsy Workshop

To evaluate our initial experience with a multi-institutional workshop model of MRI/US fusion biopsy simulation for resident education.

Residents from 6 Chicago area urology programs participated in a MRI/US fusion biopsy workshop, which incorporated a 30 minute didactic session followed by hands-on simulation. The workshop was facilitated by fellowship-trained university faculty members and company representatives of MRI/US fusion technologies who provided teaching assistance and verbal feedback. Participants completed pre- and post-test nonvalidated 4-item questionnaires graded on a Likert scale. Information on resident prior experience with TRUS and MRI/US fusion biopsies was also collected. Pre-and postquestionnaires were compared with paired t tests for each survey domain (P <.05 were considered significant).

Thirty-three residents (PGY 1-6, median PGY 3) participated in the workshop. 13 (40.6%) residents reported performing between 51 and 100 TRUS biopsies previously. Twenty-one (65.6%) reported being familiar with PIRADS v2 interpretation of prostate MR imaging, however 17 (53.1%) had never previously performed a MRI/US fusion biopsy. Analysis of pre- and post-test questionnaires showed significant increases in all 4 survey domains (P <.05). Residents demonstrated increased familiarity with indications for fusion biopsy (mean difference = +0.59), preparation for fusion biopsy (mean difference = +1.16), methods of MRI to TRUS image registration (mean difference = +1.38), and the advantages/disadvantages of perineal vs TRUS fusion biopsy (mean difference = +1.25).

This workshop model which combines didactics followed by hands-on simulation training is an effective method for increasing the knowledge and familiarity with MRI/US fusion biopsy of trainees.
