A simulation-based randomized controlled trial was designed with the objective to assess the time needed to achieve spinal stabilization using a scoop stretcher compared to a vacuum mattress.

A simulation-based randomized controlled trial was designed with the objective to assess the time needed to achieve spinal stabilization using a scoop stretcher compared to a vacuum mattress. The participants will be recruited among healthcare workers from one Emergency Medical Service. Then, the participants will first act as patient and undergo spinal stabilization from an other team, afterwards they will have to complete a spinal stabilization either using a scoop stretcher or a vacuum mattress, depending on allocation regarding randomization. The sessions will be video recorded to allow subsequent assessment.

Inclusion Criteria:

• registered paramedics or emergency medical technician (EMT) actually working in the ambulance service.

Exclusion Criteria:

• member of study investigators

No adverse events as it was no risk to participants (simulation study).

It is important to acknowledge that the reported times are applicable only when all the required equipment is readily available at the scene. Several factors should be taken into account when interpreting the results. The study's design was monocentric, and the participants involved healthy volunteers rather than actual patients. Additionally, the sample size was small, which may limit the generalizability of the findings. Open-label design, subject to possible bias.

Due to nature of therapy, it is impossible to mask participants, care provider, investigators or outcomes assessors. Statistician will however be blinded to allocation.
