Objective: To measure the verbal communication between emergency medical technician-paramedics (EMT-Ps) and physicians in an emergency department trauma room (EDTR) before and after an educational intervention.
Methods: Using a before-after design, we audio-recorded paramedic verbal trauma reports in a large EDTR over a 12-week period. Trained research assistants subsequently queried physicians about information from the paramedic report in a separate interview. Physician recall was quantified. Midway through the study, a web-based, educational intervention designed to enhance paramedic communication skills was administered to the three participating emergency medical services (EMS) systems. Physician recall of more severely injured trauma cases (red triage) was compared with their recall of less severely injured cases (yellow triage). Further comparisons were made between pre- and post-intervention physician recalls, and the extent to which physicians recalled three distinct categories of paramedic verbal information was measured.
Results: Overall, physicians accurately recalled 36% of the paramedic verbal report. Information from less severe "yellow" trauma reports was recalled more accurately than that from more severe "red" traumas (40% vs. 34% p = 0.02). Pre- and post-intervention recalls were not significantly different (33% vs. 38% p = 0.16). Physicians' recall of information about the crash scene (46%) was significantly greater than their recall of information about the patient's health status (34%) or information about prehospital patient care (30%) (p = 0.0012).
Conclusion: Physicians appear to recall paramedic verbal reports about trauma patients poorly. Recall is probably multifactorial and will require further work to design appropriate interventions.
