(1002) 3D Printed Simulation Model Facilitates Caregiver Procedural Education Within a Medical Device Clinical Trial

Introduction: Effective education is critical for ensuring safe and proficient use of medical devices, particularly those that require nasal insertion. While it is common for informational brochures to be provided in clinics, there is often little opportunity to practice insertion. We tested an innovative simulation-based training approach for a novel nasopharyngeal-oropharyngeal (NPOP) device designed to enhance procedural proficiency among caregivers of patients with hypotonic upper away collapse.

Methods: We designed a 3D-printed simulator for conceptual and procedural education for caregivers of children with cerebral palsy and trisomy 21. Conducted as part of a randomized controlled trial, this high-fidelity model aimed to enhance caregiver education and procedural rehearsal. Simulator validation involved caregivers reviewing an instructional brochure and practicing insertion and removal on a 3D model. Caregivers completed a survey about the helpfulness of the simulator to assess their understanding and confidence with NPOP insertion process.

Results: Of 30 participants, 29 (97%) reported that the simulator was easy to understand and was helpful to understand the insertion process. Overall, 86% strongly agreed and 13% agreed that the simulator improved their confidence in using the NPOP. Similarly, 90% strongly agreed and 7% agreed that the simulator improved understanding of how the NPOP worked. All respondents recommended the simulator and provided comments such as: "liked how I was able to practice and see it”; “very clear, three-dimensional representation…is tactile and visual in a way that promotes quick understanding”.

Conclusions: Our multidisciplinary team, heavily influenced by family participation and feedback, demonstrated that the 3D simulator addresses a need for caregiver education on NPOP management in complex pediatric patients. In-clinic demonstrations and rehearsals enhanced family engagement. This practical, patient-centered simulation, highly relevant for Otolaryngologists, improved caregiver understanding and confidence during NPOP placement.
