Method for determining automatic external defibrillator need at mass gatherings.

OBJECTIVES: A method for determining the number of automatic external defibrillators (AEDs) required for a 3-min response at mass gatherings has been described previously. Our study sought to modify the method, replicate it, then validate the results. METHODS: Emergency medical technicians (EMTs) were timed walking defined courses in a football stadium. Velocities were obtained for a horizontal distance and ascending/descending upper and lower decks. This was replicated in a basketball arena. To validate, actual response times were compared to predicted times for predetermined distances in each venue. Predicted response times were calculated using the second standard deviation velocities as the most pessimistic. Numbers of AEDs needed were calculated using predicted response times for each venue's longest distance. RESULTS: Average velocities in m/s (football) were horizontal 1.7, lower deck 1.6 ascending and 1.4 descending, upper deck 1.0 ascending and 1.1 descending. Average velocities (basketball) were horizontal 1.7, lower deck 1.2 ascending and descending, upper deck 0.9 ascending and descending. In the validation phase, every EMT completed the four predetermined courses within the predicted intervals. Predicted response times were 363 s for the longest football stadium distance, and 187 s for the basketball arena. For a 3-min (180 s) response, the number of AEDs required can be calculated. CONCLUSION: This method was easily replicated and appears to be useful for determining the number of AEDs at mass gatherings. The number of AEDs needed for any desired response interval can be calculated using the predicted response time for the longest distance within an arena.

The educational intervention "GRIEV_ING" improves the death notification skills of residents.

BACKGROUND: Death notification is a common, difficult, and emotionally laden communication for emergency physicians. Teaching emergency medicine residents the skills for success in this communication is an important focus for educators. To accomplish this task, educators need practical, proven teaching and assessment tools focused on death notification skills. OBJECTIVES: To test the hypothesis that a teaching module, based on the mnemonic "GRIEV_ING," could improve resident confidence, competency, and communication skills when delivering a death notification. METHODS: The GRIEV_ING intervention consisted of a two-hour educational session composed of small-group, role-play, and didactic experiences. The authors used a pre-post-retention repeated-measures design to test their hypothesis immediately following and three months after training. For each assessment cycle, three quantitative measures were collected: self-confidence, relationship-communication, and competency. Relationship-communication and competency scores were collected during simulated survivor encounters. RESULTS: Complete data for 20 residents were obtained. Significant improvements were noted in resident confidence scores at the pre-post (F = 16.7, p <0.0001) and pre-retention (F = 14.0, p = 0.001) comparisons. Likewise, significant improvements were noted in resident competence scores at the pre-post (F = 4.7, p = 0.04) and pre-retention (F = 8.8, p = 0.008) comparisons. Resident relationship-communication scores were uniformly high, and there was no significant change in this score across study intervals. CONCLUSIONS: This study demonstrates that a defined educational intervention focused on the GRIEV_ING mnemonic can improve physician confidence and competence in death notification.
