Three Instructional Interventions for Prehospital Cervical Spinal Immobilization by Laypeople
July 25, 2022 updated by: Jaimo Ahn, University of Michigan
Measuring the Effectiveness of Three Instructional Interventions for Prehospital Cervical Spinal Immobilization by Laypeople: A Randomized Clinical Trial
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.

Detailed Description
Road traffic injuries (RTIs) are the largest contributor to the global injury burden, which disproportionately affects low- and middle-income countries (LMICs).
Traumatic spinal cord injury (TSCI) is the highest contributor to years lived disabled (YLDs) resulting from RTIs, accounting for 74.8% of YLDs from RTI.
With a lack of robust emergency medical services (EMS), there has been increasing reliance on layperson bystanders to respond to RTIs in LMICs.
Early spinal immobilization has the potential to limit neurological deficits secondary to TSCI and morbidity.
Bystanders may be trained in-person or point-of-care (POC) instruction may be provided, as exists with automated external defibrillators and tourniquets.
However, it is unknown if bystanders equipped with POC instruction are as effective as bystanders with in-person training for c-spine immobilization.
Therefore, POC instructional interventions were developed 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.
The POC instructional flashcard was first piloted with an initial cohort of participants who were not assigned to any longitudinal follow-up date to pilot POC instructional interventions for c-spine immobilization and receive feedback for instructional flashcard revision prior to launching the "trial."
Data from these participants is not considered part of the "trial" for analytic purposes.
This entire testing process is with participants who are healthy volunteers and researchers simulating spinal injury victims to test which method of instruction is most effective and durable for understanding.

Experimental: Audio recording with instructional flashcard (version 1) with cervical-collar - no follow-up
Prior to randomization to 1 or 2 month follow up, these participants served as an initial cohort of participants who were not assigned to any longitudinal follow-up date so that the POC instructional flashcard could first be piloted to receive feedback for instructional flashcard revision prior to launching the "trial" after participants expressed concern about ambiguity in the instructional flashcard.
Data from these participants is not considered part of the "trial" for any analytic purposes.
Revisions to the instructional flashcard were made.
