Improved Medical Student Satisfaction and Test Performance With a Simulation-Based Emergency Medicine Curriculum: A Randomized Controlled Trial

STUDY OBJECTIVE We determine the effect of a simulation-based curriculum on fourth-year medical student test performance and satisfaction during an emergency medicine clerkship. METHODS This was a randomized controlled study using a crossover design for curriculum format and an anonymous end-of-rotation satisfaction survey. Students were randomized into 2 groups. One group started the rotation with simulation and the other with group discussion. Midrotation, they each crossed over to the opposite format. All students subsequently completed the same multiple choice examination. We assessed paired samples of the number of questions missed for material taught in each format. Students rated satisfaction with a 5-point Likert scale framed as attitude toward simulation compared with group discussion. Scores ranged from 5, signifying strong agreement with a statement, to 1, signifying strong disagreement. RESULTS Ninety students (99%) completed the multiple choice test. Significantly fewer questions were missed for material presented in simulation format compared with group discussion, with a mean difference per student of 0.7 (95% confidence interval [CI] 0.3 to 1.0; P=.006). This corresponds to mean scores of 89.8% for simulation and 86.4% for group discussion. Eighty-eight (97%) students completed the satisfaction survey. Students rated simulation as more stressful (mean 4.1; 95% CI 3.9 to 4.3), but also more enjoyable (mean 4.5; 95% CI 4.3 to 4.6), more stimulating (mean 4.7; 95% CI 4.5 to 4.8), and closer to the actual clinical setting (mean 4.6; 95% CI 4.4 to 4.7) compared with group discussion. CONCLUSION A simulation-based curriculum yielded measurable benefits. Students demonstrated a small improvement in learning and were more satisfied with the simulation-based curriculum compared with group discussion.

Improved fourth-year medical student clinical decision-making performance as a resuscitation team leader after a simulation-based curriculum.

Objective: To determine the impact of simulation-based instruction on student performance in the role of emergency department resuscitation team leader. Methods: A randomized, single-blinded, controlled study using an intention to treat analysis. Eighty-three fourth-year medical students enrolled in an emergency medicine clerkship were randomly allocated to two groups differing only by instructional format. Each student individually completed an initial simulation case, followed by a standardized curriculum of eight cases in either group simulation or case-based group discussion format before a second individual simulation case. A remote coinvestigator measured eight objective performance end points using digital recordings of all individual simulation cases. McNemar &khgr;2, Pearson correlation, repeated measures multivariate analysis of variance, and follow-up analysis of variance were used for statistical evaluation. Results: Sixty-eight students (82%) completed both initial and follow-up individual simulations. Eight students were lost from the simulation group and seven from the discussion group. The mean postintervention case performance was significantly better for the students allocated to simulation instruction compared with the group discussion students for four outcomes including a decrease in mean time to (1) order an intravenous line; (2) initiate cardiac monitoring; (3) order initial laboratory tests; and (4) initiate blood pressure monitoring. Paired comparisons of each student’s initial and follow-up simulations demonstrated significant improvement in the same four areas, in mean time to order an abdominal radiograph and in obtaining an allergy history. Conclusions: A single simulation-based teaching session significantly improved student performance as a team leader. Additional simulation sessions provided further improvement compared with instruction provided in case-based group discussion format.

Medical student case presentation performance and perception when using mobile learning technology in the emergency department

Abstract Background Hand-held mobile learning technology provides opportunities for clinically relevant self-instructional modules to augment traditional bedside teaching. Using this technology as a teaching tool has not been well studied. We sought to evaluate medical students’ case presentation performance and perception when viewing short, just-in-time mobile learning videos using the iPod touch prior to patient encounters. Methods Twenty-two fourth-year medical students were randomized to receive or not to receive instruction by video, using the iPod Touch, prior to patient encounters. After seeing a patient, they presented the case to their faculty, who completed a standard data collection sheet. Students were surveyed on their perceived confidence and effectiveness after using these videos. Results Twenty-two students completed a total of 67 patient encounters. There was a statistically significant improvement in presentations when the videos were viewed for the first time (p = 0.032). There was no difference when the presentations were summed for the entire rotation (p = 0.671). The reliable (alpha = 0.97) survey indicated that the videos were a useful teaching tool and gave students more confidence in their presentations. Conclusions Medical student patient presentations were improved with the use of mobile instructional videos following first time use, suggesting mobile learning videos may be useful in medical student education. If direct bedside teaching is unavailable, just-in-time iPod touch videos can be an alternative instructional strategy to improve first-time patient presentations by medical students.

Third-year Medical Student Rotations in Emergency Medicine: A Survey of Current Practices

OBJECTIVES Exposure to emergency medicine (EM) is a crucial aspect of medical student education, yet one that is historically absent from third-year medical student training. There are limited data describing the existing third-year rotations. The goal of this study is to identify the content and structure of current EM rotations specific to third-year students. METHODS An institutional review board-approved survey of clerkship characteristics was designed by consensus opinion of clerkship directors (CDs). The survey was distributed to 32 CDs at institutions with known EM clerkships involving third-year students. RESULTS Twenty-three (72%) CDs responded to the survey. Sixty-five percent have rotations designed specifically for third-year students, of which 33% are required clerkships. Twenty-seven percent of rotations have prerequisite rotations; 37% of rotations include shifts in the pediatric ED. Clinical time averages four 8-hour shifts per week for 4 weeks; all rotations include weekly didactic time specific to third-year students. A wide variety of textbooks are used; some programs employ simulation labs. Two-thirds of the rotations have a required write-up or presentation; 53% include a final exam. Student evaluations are written and verbal. Most rotations receive more support from the EM departments than from the medical schools for physical space, administrative needs, and faculty time. Among those surveyed, students from institutions requiring a third-year EM rotation have a higher rate of application to EM residencies. CONCLUSIONS There is variability in the content and structure of existing third-year EM rotations, as well as in financial and administrative needs and support. These data can help to inform CDs and departments that are starting or modifying EM third-year rotations, as well as contribute to the development of curricula for such rotations.

SMALL BOWEL PERFORATION SECONDARY TO FISH BONE INGESTION MANAGED NON-OPERATIVELY

BACKGROUND The presurgical diagnosis of foreign body (FB)-induced bowel perforation is exceedingly difficult. Perforation most commonly occurs in the ileocecal region and typically mimics diagnoses more common to the right lower quadrant (RLQ), including appendicitis and diverticulitis. OBJECTIVES This report will discuss the events of this particular case of fish bone ingestion and subsequent small bowel perforation and the epidemiology, diagnosis, and management of FB ingestions. CASE REPORT This case describes a 28-year-old man who presents with a 4-h history of sharp, stabbing abdominal pain localized to the RLQ. Abdominal computed tomography revealed a 1.5-cm curvilinear foreign body traversing through a loop of small bowel in the RLQ. Upon further questioning, the patient recalled eating northern pike 2 days before. During his hospital stay, the patient noted improvement of his symptoms and thus was managed non-operatively without complication. The patient was discharged after complete resolution of his abdominal pain on hospital day number 2. CONCLUSION This represents a rare case of small bowel perforation secondary to fish bone ingestion that was managed non-operatively without complication.

No relationship between measures of clinical efficiency and teaching effectiveness for emergency medicine faculty

Objectives Emergency medicine (EM) doctors affiliated with academic institutions experience professional tension between providing excellent, timely care for patients and high-quality bedside instruction for residents and medical students. The goal of this study was to assess the relationship between measures of faculty clinical efficiency and teaching effectiveness. Methods This was a retrospective review of data from a single academic institution with an annual census of 55 000. Faculty clinical efficiency was measured by two variables: the relative value unit (RVU)/h ratio and average ‘door to discharge’ time. Teaching effectiveness was estimated by determining the average ‘overall teaching’ scores derived from anonymous EM resident and senior medical student evaluations. Relationships were assessed using the Spearmans correlation coefficient. Results There was no statistically significant relationship (p>0.050) between measures of faculty clinical efficiency and teaching effectiveness. Conclusion These data replicate previous findings that clinical productivity has no correlation with teaching effectiveness for emergency medicine faculty doctors.

Developing a Third‐year Emergency Medicine Medical Student Curriculum: A Syllabus of Content

Emergency medicine (EM) educators have published several curricular guides designed for medical student rotations and experiences. These guides primarily provided brief overviews of opportunities to incorporate EM into all 4 years of the medical student curriculum, with one specific to the fourth year. However, there are no published guidelines specific to third-year medical students rotating in EM. Given the differences between third-year and fourth-year students in terms of clinical experience, knowledge, and skills, the Clerkship Directors in Emergency Medicine (CDEM) established the Third-year EM Medical Student Curriculum Work Group to create a third-year curriculum. The work group began this process by developing consensus-based recommendations for the content of a third-year medical student EM rotation, which are presented in this syllabus.

Integrating Emergency Medicine Principles and Experience Throughout the Medical School Curriculum: Why and How

The management of acutely ill and injured patients is an essential component of medical student education, yet the formal integration of emergency medicine (EM) into the medical school curriculum has progressed slowly since the inception of the specialty. Medical student interest and the number of resident positions in the National Resident Matching Program are higher than any time in the past, yet students often find access to EM faculty and clinical experience limited to a fourth-year rotation. Incorporating EM into all years of the undergraduate medical student curriculum can offer unique educational experiences and enhance exposure to the necessary and recommended knowledge and skills students must attain prior to graduation. Academic emergency physicians (EPs) should advocate our specialtys importance in their medical school curricula using a proactive approach and actively involve themselves in medical student education at all stages of training. The goals of this article are to describe several approaches for EM faculty to expand medical student exposure to the specialty and enhance student experiences in the core principles of EM throughout the undergraduate medical curriculum.

Impact of group size on the effectiveness of a resuscitation simulation curriculum for medical students.

Background: Simulation requires involvement from participants. However, it is unknown to what extent simulation effectiveness is a function of the number of participants. Purpose: This study assessed the impact of varying group size on medical students’ subjective experience of simulation and on postsimulation exam performance. Methods: Medical students were randomly assigned to groups of 2, 3, or 4. Retrospective assessment was done through a survey assessing confidence and knowledge as it relates to resuscitation and statements related to group size. Performance on a postsimulation exam was analyzed. Results: There were significant increases in students’ confidence and knowledge following simulation. There were no significant differences in student perception of the effectiveness or realism of the simulation or in performance on the postsimulation exam as a function of group size. Conclusions: Students feel that simulation is an effective way to learn medical knowledge. Varying group size had no effect on students’ subjective experience or exam performance.

Implementing a third-year emergency medicine medical student curriculum.

BACKGROUND Emergency medicine (EM) is commonly introduced in the fourth year of medical school because of a perceived need to have more experienced students in the complex and dynamic environment of the emergency department. However, there is no evidence supporting the optimal time or duration for an EM rotation, and a number of institutions offer third-year rotations. OBJECTIVE A recently published syllabus provides areas of knowledge, skills, and attitudes that third-year EM rotation directors can use to develop curricula. This article expands on that syllabus by providing a comprehensive curricular guide for the third-year medical student rotation with a focus on implementation. DISCUSSION Included are consensus-derived learning objectives, discussion of educational methods, considerations for implementation, and information on feedback and evaluation as proposed by the Clerkship Directors in Emergency Medicine Third-Year Curriculum Work Group. External validation results, derived from a survey of third-year rotation directors, are provided in the form of a content validity index for each content area. CONCLUSIONS This consensus-derived curricular guide can be used by faculty who are developing or revising a third-year EM medical student rotation and provide guidance for implementing this curriculum at their institution.
