Teaching Methods Utilized During Medical Resuscitations in an Academic Emergency Department.

INTRODUCTION: One important skill that an emergency medicine trainee must learn is the resuscitation of the critically ill patient. There is research describing clinical teaching strategies used in the emergency department (ED), but less is known about specific methods employed during actual medical resuscitations. Our objective was to identify and describe the teaching methods used during medical resuscitations. METHODS: This was a prospective study involving review of 22 videotaped, medical resuscitations. Two teams of investigators first each reviewed and scored the amount and types of teaching observed for the same two videos. Each team then watched and scored 10 different videos. We calculated a Cohen's kappa statistic for the first two videos. For the remaining 20 videos, we determined means and standard deviations, and we calculated independent two-tailed t-tests to compare means between different demographic and clinical situations. RESULTS: The Cohen's kappa statistic was K=0.89 with regard to number of teaching events and K=0.82 for types of teaching observed. Of the resuscitations reviewed, 12 were in coding patients. We identified 148 episodes of teaching, for an average of 7.4 per resuscitation. The amount of teaching did not vary with regard to whether the patient was coding or not (p=0.97), nor based on whether the primary learner was a junior or senior resident (p=0.59). Questioning, affirmatives and advice-giving were the most frequently observed teaching methods. CONCLUSION: Teachers use concise teaching methods to instruct residents who lead medical resuscitations. Further research should focus on the effectiveness of these identified strategies.

Does the Flipped Classroom Improve Learning in Graduate Medical Education?

BACKGROUND: The flipped classroom model for didactic education has recently gained popularity in medical education; however, there is a paucity of performance data showing its effectiveness for knowledge gain in graduate medical education. OBJECTIVE: We assessed whether a flipped classroom module improves knowledge gain compared with a standard lecture. METHODS: We conducted a randomized crossover study in 3 emergency medicine residency programs. Participants were randomized to receive a 50-minute lecture from an expert educator on one subject and a flipped classroom module on the other. The flipped classroom included a 20-minute at-home video and 30 minutes of in-class case discussion. The 2 subjects addressed were headache and acute low back pain. A pretest, immediate posttest, and 90-day retention test were given for each subject. RESULTS: Of 82 eligible residents, 73 completed both modules. For the low back pain module, mean test scores were not significantly different between the lecture and flipped classroom formats. For the headache module, there were significant differences in performance for a given test date between the flipped classroom and the lecture format. However, differences between groups were less than 1 of 10 examination items, making it difficult to assign educational importance to the differences. CONCLUSIONS: In this crossover study comparing a single flipped classroom module with a standard lecture, we found mixed statistical results for performance measured by multiple-choice questions. As the differences were small, the flipped classroom and lecture were essentially equivalent.

Low Back Pain in the Emergency Medicine Department: A Flipped Classroom Module.

INTRODUCTION: Current residency didactic schedules that are built upon hour-long, lecture-based presentations are incongruous with adult learning theory and the needs of millennial generation residents. An alternative to the traditional lecture, the flipped classroom involves viewing a short video lecture at home, followed by an active discussion during class time. This module was developed for emergency medicine residents and rotating medical students without previous training on the subject. METHODS: The at-home portion of the module was designed to be delivered at home, while the in-class discussion was designed to be carried out over 30-45 minutes during a regularly scheduled didactic time. Small-group size may be determined by faculty availability, though groups of five are optimal. There is no requirement for faculty preparation prior to the in-class session. Associated materials include objectives, the at-home video, a discussion guide for faculty facilitators, a case-based handout for students and residents, and assessment questions. We assessed our module with a pretest, immediate posttest, and the posttest again after 90 days. RESULTS: The mean pretest score was 66%, mean posttest score 76%, and mean retention test score 66%. There was an immediate increase of 10%, which did not remain at 90 days. DISCUSSION: We developed a flipped classroom module that can be implemented in any emergency medicine residency or clerkship. It addresses the theoretical challenges posed to traditional conference didactics by increasing the focus on problem solving and self-directed learning.
