Research design: a prospective observational study. Aim and Methods: to evaluate the ability of emergency life-saving technicians (ELSTs) to diagnose anaphylaxis by comparing the diagnoses of anaphylaxis requiring adrenaline administration by ELSTs in the field with those made by physicians at medical institutions after transport. The study will evaluate the positive predictive value and positive likelihood ratio and others of the decisions by ELSTs against the decisions by the physicians. The selection of ELSTs will be done through public recruitment to organizations such as prefectural and regional medical control (MC) committees and fire departments. ELSTs who belong to participating organizations will be provided with explanatory documents and videos and asked to provide consent. The study team will guide ELSTs who have completed the preparatory e-learning (which includes the overview of the study, basic knowledge of anaphylaxis, judgments of anaphylaxis and adrenaline administration in this study, and the use of observation cards) to collect data.
