The development process from a low- to high-fidelity, low-cost pudendal nerve block task trainer

Purpose: Describe the concepts and iterative process needed to develop a novel, low-cost, low-fidelity pudendal nerve block simulation model into a high-fidelity task trainer.

 

Background: The initial pudendal nerve block model was developed using commonly found craft supplies costing $20. It was presented at APGO 2021. Modifications were gathered from a simulation session with 34 obstetrics and gynecology and family medicine residents, and a group of simulation experts.

 

Methods: Survey data was collected and collated for all session participants followed by review of the model by simulation experts. Additionally, key concepts in simulation model design were discussed including ease of construction and durability; model haptics; reproductivity and verification of correct instrument movements and placement; ability to use the device to teach and test; and ability to differentiate between provider skill.

 

Results: Issues raised by participants included improving the feel (space confinements); durability of the materials; and procedural haptics (clay too rigid and loss of resistance when traversing the ligament and verification of placement). Issues raised by experts included device support and dimensions; durability and haptics of the structures; ability to guide or verify proper placement; and ability to change feel of ischial spines and incorporation of a simulated ligament.

 

Discussions: We present the approach utilized to refine task trainer development utilizing a novel, low-cost, low-fidelity model as an example. Incorporation of the participant and expert responses of key task trainer development concepts, we present a new and vastly improved high-fidelity, low-cost simulation model for pudendal nerve block.
