Human errors in emergency medical services: a qualitative analysis of contributing factors.

Background: The dynamic and challenging work environment of the prehospital emergency care settings creates many challenges for paramedics. Previous studies have examined adverse events and patient safety activities, but studies focusing on paramedics' perspectives of factors contributing to human error are lacking. In this study, we investigated paramedics' opinions of the factors contributing to human errors.

Method: Data was collected through semi-structured individual interviews (n = 15) with paramedics and emergency medical field supervisors in Finland. The data was analyzed using inductive content analysis. Consolidated criteria for reporting qualitative research were used.

Results: Contributing factors to human errors were divided into three main categories. The first main category, Changing work environment, consisted of two generic categories: The nature of the work and Factors linked to missions. The second main category, Organization of work, was divided into three generic categories: Inadequate care guidelines, Interaction challenges and Challenges related to technological systems. The third main category, Paramedics themselves, consisted of four generic categories: Issues that complicate cognitive processing, Individual strains and needs, Attitude problems and Impact of work experience.

Conclusion: Various factors contributing to human errors in emergency medical services (EMS) settings were identified. Although many of them were related to individual factors or to the paramedics themselves, system-level factors were also found to affect paramedics' work and may therefore negatively impact patient safety. The findings provide insights for organizations to use this knowledge proactively to develop their procedures and to improve patient safety.
