Background: Pediatric drug dosing errors occur at a high rate in the prehospital environment. Objective: To describe paramedic training and practice regarding pediatric drug administration, exposure to pediatric drug dose errors and safety culture among paramedics and EMS agencies in a national sample. Methods: An electronic questionnaire was sent to a random sample of 10,530 nationally certified paramedics. Descriptive statistics were calculated. Results: There were 1,043 (9.9%) responses and 1,014 paramedics met inclusion criteria. Nearly half (43.0%) were familiar with a case where EMS personnel delivered an incorrect pediatric drug dose. Over half (58.5%) believed their initial paramedic program did not include enough pediatric training. Two-thirds (66.0%) administered a pediatric drug dose within the past year. When estimating the weight of a pediatric patient, 54.2% used a length-based tape, while 35.8% asked the parent or guardian, and 2.5% relied on a smart phone application. Only 19.8% said their agency had an anonymous error-reporting system and 50.7% believed they could report an error without fear of disciplinary action. For solutions, 89.0% believed an EMS-specific Broselow-Luten Tape would be helpful, followed by drug dosing cards in milliliters (83.0%) and changing content of standardized pediatric courses to be more relevant (77.7%). Conclusion: This national survey demonstrated a significant number of paramedics are aware of a pediatric dosing error, safety systems specific to pediatric patients are lacking, and that paramedics view pediatric drug cards and eliminating drug calculations as helpful. Pediatric drug-dosing safety in the prehospital environment can be improved.

Medication dosing errors occur in up to 17.8% of hospitalized children. There are limited data to describe pediatric medication errors by emergency medical services (EMS) paramedics. It has been shown that paramedics have infrequent encounters with pediatric patients. To characterize medication dosing errors in children treated by EMS. We studied patients aged ≤11 years who were treated by paramedics from eight Michigan EMS agencies from January 2004 through March 2006. We defined a medication dosing error as ≥20% deviation from the weight-appropriate dose, as determined by the patient's reported weight in the prehospital medical record or by use of the Broselow-Luten tape (BLT). We studied errors in administering six EMS medications commonly given to children: albuterol, atropine, dextrose, diphenhydramine, epinephrine, and naloxone. There were 5,547 children aged ≤11 years who were treated during the study period, of whom 230 (4.1%) received drugs and had a documented weight. These patients received a total of 360 medication administrations. Multiple drug administrations occurred in 73 cases. Medication dosing errors occurred in 125 of the 360 drug administrations (34.7%; 95% confidence interval [CI] 30.0, 39.8). Relative drug dosage errors (with 95% CI) were as follows: albuterol 23.3% (18.4, 29.1), atropine 48.8% (34.3, 63.5), diphenhydramine 53.8% (29.1, 76.8), and epinephrine 60.9% (49.9, 73.9). The mean error (± standard deviation) for intravenous/intraosseous 1:1000 epinephrine overdoses was 808% ± 428%. The mean error (± standard deviation) for intravenous/intraosseous 1:1000 epinephrine underdoses was 35.5% ± 27.4%. Medications delivered in the prehospital care of children were frequently administered outside of the proper dose range when compared with patient weights recorded in the prehospital medical record. EMS systems should develop strategies to reduce pediatric medication dosing errors.

Objective. To determine which airway endotracheal tube (ET), Combitube (CT), or Laryngeal Mask Airway (LMA) has the shortest time to successful ventilation in three nontraditional prehospital airway scenarios. Methods. Prospective randomized cohort study of emergency medicine (EM) residents, faculty EM physicians, andparamedics (EMT-P). Subjects were instructed to place an airway in a mannequin in three scenarios: mannequin supine under a table with head abutting a wall, mannequin sitting upright with access from behind, andmannequin lying on its side with access facing the mannequin. The number of airway placement attempts andtime to successful ventilation were recorded. Results. Twenty-five resident physicians, 9 faculty physicians, and22 EMT-Ps participated. No significant difference was found between the different airways in the number of attempts to successfully ventilate. EMT-Ps demonstrated significantly faster times to successful ventilation for all scenarios versus physicians (e.g., supine scenario with ET, EMT-P median time 57 seconds, physician median time 96 seconds) except for the mannequin lying on its side where there was no significant difference. The time to ventilation for all scenarios was less with the LMA versus ET or CT versus ET, except in the sitting scenario where ET andCT were comparable Conclusions. In this mannequin model of restricted airway access, LMA resulted in significantly faster times to ventilation versus ET andCT in all but one scenario. Further consideration andstudy using airways other than ET are warranted for situations with restricted access to the patient's airway.
