Three Instructional Interventions for Prehospital Cervical Spinal Immobilization by Laypeople

It is not known if bystanders equipped with point-of-care (POC) instruction are as effective as bystanders with in-person training for c-spine immobilization. Therefore, POC instructional interventions were developed during this study in response to the scalability challenges associated with in-person training to measure the comparative effectiveness and skill retention of POC instructions vs in-person training using a randomized clinical trial design.
