Mass-casualty incidents (MCI) are a highly important issue in disaster medicine today. In this context, professional first responders play a fundamental role as they provide preparedness and initial care to the injured. The aim of this review is to describe the form and impact of different didactic concepts in triage exercises to prepare for an MCI response.

A Scoping review search was conducted in the databases PubMed, Medline, and Psyndex as an initial examination of this topic.

Seventeen studies were included in this review. Of the reviewed studies, 52.9% followed a randomized controlled trial design with pre-post intervention measurement. The interventions implemented in the studies were associated with an increase in knowledge and/or practical skills. Of media-based interventions, 42.9% show a comparable and 57.1% greater training effect than conventional teaching methods. According to 4 studies, technical and non-technical aids increase the triage accuracy.

The benefits of media-based interventions and of technical and non-technical aids should be evaluated by a subsequent systematic review with a broader database and search terms of studies. The differences between different triage algorithms need to be investigated in future studies. It must be noted that intervention is preferable to non-intervention.
