Development of an immobilization device based on the criteria from different users
This study is set in the context of the care of trauma patients with suspected spine trauma and the use of immobilization devices to prevent secondary trauma. The aim of the current study is develop a concept of vest immobilization device that meets the needs of the users - in this case defined as patients, care teams, and cleaning/decontamination professionals. To this end, we developed a list of requirements and restrictions defined by a usability test with PreHospital Trauma Life Support (PHTLS) and Advanced Trauma Life Support (ATLS) teams. Then a list of solutions, realized through benchmarking, shows the best practices from industry. Finally, a multi-criteria decision-making analysis defines the importance of requirements and shows the best solutions to new immobilization device development. Based on the results obtained, a concept of immobilization device created for patients with suspected spinal injury presents an alternative that meets the user’s needs.
