Testing and validation of a low-cost cystoscopy teaching model: a randomized controlled trial

Area of Science:

• Medical Education
• Surgical Simulation
• Urology Training

Background:

• Cystourethroscopy is a crucial skill for obstetrician-gynecologists.
• Effective training tools are needed to enhance resident proficiency.
• Low-cost simulation models offer potential for widespread adoption.

Purpose of the Study:

• To evaluate the efficacy of a low-cost cystoscopy model for resident training.
• To validate the model as a teaching tool for cystourethroscopy.
• To compare skill acquisition using the model versus standard methods.

Main Methods:

• Randomized, controlled, evaluator-blinded study.
• 29 obstetrician-gynecologist residents assessed using Objective Structured Assessment of Technical Skills (OSATS) checklists.
• Residents randomized to a didactic study arm (cystoscopy model) or control arm.

Main Results:

• Study group showed decreased cystoscope assembly time (128.8s to 54.9s; P=.005).
• Significant improvements in task-specific checklist scores (59.3 to 92.9; P<.001) and global rating scales (61.0 to 87.8; P<.001).
• Study arm outperformed control arm in checklist scores (P<.001), global ratings (P=.002), and knowledge quizzes (P=.011).

Conclusions:

• The bladder model is a valid tool for improving cystourethroscopy performance.
• The model enhances both practical skills and knowledge among ob-gyn residents.
• Low-cost simulation effectively bridges the gap in surgical training.
