PurposeThe aim of this study was to identify the perceived competence of Finnish paramedics to operate in different chemical, biological, radiological, nuclear, and explosive (CBRNE) incidents.Design/methodology/approachThis was a descriptive cross-sectional survey study. The material was collected using a previously developed questionnaire, which was modified in accordance with the study aim. The target group was paramedics of the Päijät-Häme region of Finland (N = 166), whose role entailed active operational duties during the survey. Descriptive statistical methods were used.FindingsParamedics reported low levels of training related to CBRNE incidents, and most felt that more training was needed. Chemical and explosive-related incidents were regarded as more likely to occur than others. Additionally, paramedics with more work experience perceived themselves as having higher competence only in chemical and explosive-related incidents. Overall, paramedics perceived their CBRNE competence as low.Originality/valueThe perceived CBRNE competence of paramedics has not been studied sufficiently. Paramedics felt chemical and explosive related incidents were more likely to occur than others, and competence related to those two was also better perceived. This study showed that paramedics could benefit from more training to respond to CBRNE incidents to improve perceptions of their competence. However, the desired competence, actual competence, and appropriate training to respond to CBRNE incidents require further research.
