A validated low-cost training model for suprapubic catheter insertion

Objective To describe an anatomically correct simulator for use in suprapubic catheter (SPC) insertion training. Methods A scale reproduction of an adult male pelvis with bony landmarks and a subcutaneous fluid-filled reservoir was created using platinum cured silicone rubber. This model was evaluated by 6 expert urologists for content validity with a 16-item 5-point rating scale used to evaluate domains relevant to the simulator—physical attributes, realism of experience, realism of materials, and global rating. The simulator was used by 25 general surgeons from rural practices participating in a 2-day comprehensive specialized surgical skills course. Results The domains were scored between 1 and 5; 1 being "not at all realistic" and 5 being "highly realistic, no changes needed." The average expert ratings of the domains were 3.9 (physical attributes), 4.3 (realism of experience), and 3.9 (realism of materials). The simulator was rated more valuable as a training tool (4.5) compared with a testing tool (3.8) with an average global rating of 4.1. Conclusion Experts and trainees reported high satisfaction with their experience using this simulator. Preliminary evidence suggests this simulator is a useful tool that can be integrated into training programs to facilitate learning this necessary urologic skill.
