Introduction: Management of pediatric cardiac arrest challenges the skills of prehospital care providers. Errors and error-producing conditions are difficult to identify from retrospective records. The objective of this study was to identify errors committed by prehospital care providers and the underlying causes of those errors during a simulated pediatric cardiopulmonary arrest followed by a structured debriefing., Methods: Performance criteria were defined prospectively by an advisory panel. Prehospital care providers from 6 emergency medical service agencies in Michigan participated in a simulation of an infant cardiopulmonary arrest using their own drugs, equipment, and protocols in a mobile trailer. Simulations were video recorded and played back during debriefings that were conducted immediately after the event to facilitate error analysis. Observed errors and subjects' explanations were analyzed by thematic qualitative assessment methods and descriptive statistics., Results: One hundred ninety-four subjects, including paramedics, emergency medical technicians, and emergency medical responders in various crew configurations, participated in 60 simulation sessions during a 5-month period (April to August of 2010). Error types were classified into 4 clinically important themes as follows: failure to provide adequate ventilation, failure to provide effective circulation, failure to achieve vascular access rapidly, and medication errors. Multiple underlying causes of medication dosing and other errors were identified, including cognitive, procedural, communication, teamwork, and systems factors., Conclusions: We systematically observed many types of errors and identified some of the underlying causes during a simulated, prehospital, pediatric cardiopulmonary arrest. There were numerous, multifactorial, and sometimes, synergistic causes of medication dosing errors. Emergency medical service officials can use these findings to prevent future errors.

Background: Systematic evaluation of the performances of prehospital providers during actual pediatric anaphylaxis cases has never been reported. Epinephrine medication errors in pediatric resuscitation are common, but the root causes of these errors are not fully understood., Objective: The primary objective of this study was to identify underlying causes of prehospital medication errors that were observed during a simulated pediatric anaphylaxis reaction., Methods: Two- and 4-person emergency medical services crews from eight geographically diverse agencies participated in a 20-minute simulation of a 5-year old child with progressive respiratory distress and hypotension from an anaphylactic reaction. Crews used their own equipment and drugs. A checklist-based scoring protocol was developed to help identify errors. A trained facilitator conducted a structured debriefing, supplemented by playback of video recordings, immediately after the simulated event to elicit underlying causes of errors. Errors were analyzed with mixed quantitative and qualitative methods., Results: One hundred forty-two subjects participated in 62 simulation sessions. Ninety-five percent of crews (59/62) gave epinephrine, but 27 of those crews (46%) delivered the correct dose of epinephrine in an appropriate concentration and route. Twelve crews (20%) gave a dose that was ≥5 times the correct dose; 8 crews (14%) bolused epinephrine intravenously. Among the 55 crews who gave diphenhydramine, 4 delivered the protocol-based dose. Three crews provided an intravenous steroid, and 1 used the protocol-based dose. Underlying causes of errors were categorized into eight themes: faulty reasoning, weight estimation errors, faulty recall of medication dosages, problematic references, calculation errors, dose estimation, communication errors, and medication delivery errors., Conclusion: Simulation, followed by a structured debriefing, identified multiple, underlying causes of medication errors in the prehospital management of pediatric anaphylactic reactions. Sequential and synergistic errors were observed with epinephrine delivery.
