Assessing consistency of the emergency medical services benefit score: an intra- and inter-rater reliability study in a belgian helicopter medical center

This study provides the first evidence of the high reliability of the EBS in real-life prehospital settings, confirming that the EBS can be applied consistently when assessing prehospital missions in a HEMS context. Physicians and nurses both achieved substantial agreement, supporting the tool's use across professional groups. Further research should extend to other types of prehospital emergency teams, such as ground emergency medical services and Paramedical Interventional Teams, and examine additional aspects of validity, including criterion and content validity, to further consolidate the role of the EBS in evaluating prehospital care.
