EMS protocol development, training methodologies, and equipment use decisions are based mainly on:

The foundation of EMS protocol development, training methodologies, and equipment use decisions is primarily built on evidence. This evidence is derived from research studies, clinical trials, and systematic reviews that analyze outcomes and effectiveness in emergency medical services. Evidence-based practice ensures that the protocols adopted are not only effective but also safe, leading to improved patient outcomes.

In this context, relying on evidence allows EMS professionals to implement standardized procedures that have been scientifically validated. This approach minimizes the variability that can arise from anecdotal experiences or individual biases, ensuring that all decisions are grounded in the best available data.

While experience can contribute valuable insight into the practical applications and challenges of protocols, and personal opinion or public preference might influence some aspects of service delivery, it is the robust, scientific evidence that forms the backbone of effective EMS practices. This commitment to evidence-based methodologies underscores the importance of continuous training and development in the field to ensure that practices reflect the latest research findings.
