Study Objective: Evaluate training of Ob/Gyn residents performing colpocleisis using objective structured assessment of technical skills (OSATS)

Methods: A sock model was developed to simulate and teach the steps of colpocleisis, and an expert surgeon was filmed performing the model. Educational utility was assessed by evaluating residents’ knowledge and confidence in the procedure before and after each step of the simulation using a colpocleisis task specific checklist and an OSATS scale. Each session was recorded and reviewed/scored by an expert surgeon. Step one: residents viewed the video and were then given 30 minutes to work with the model. Step two, 4-6 months later: 30 minutes to complete the colpocleisis simulation without viewing the video.

Results: 24 residents participated, 19 completed each step, and 10 videos were reviewed. All assessment scores significantly improved after the intervention for both Step 1 and Step 2. A total confidence score was calculated given excellent internal validity with Cronbach Alpha=0.97and it was improved after the intervention. Step 1 pre 25.75±14.48 & post 54.25±10.59 (p<.0001) and Step 2 pre 37.7±14.91 & post 53.4±13 57 (p<0.0003). Overall confidence improved, Step 1 pre 2.21±2.06 & post 6.38±1.97 (p<.0001) and Step 2 pre 4.05±2.42 & post 6.25±2.45 (p=0023)

Conclusions: Video instruction plus completion of an inexpensive simulation model proved effective in teaching Ob/Gyn residents a rare surgical procedure.
