A survey comparison of educational interventions for teaching pneumatic otoscopy to medical students

Abstract Background Though pneumatic otoscopy improves accurate diagnosis of ear disease, trainees lack proficiency. We evaluated the effect of three different training techniques on medical students’ subsequent reported use of basic and pneumatic otoscopy in patient encounters. Methods Pediatric clerkship students participated in an ear exam workshop with randomization to one of three educational interventions: task trainer (Life/form®, Fort Atkinson WI), instructional video, or peer practice. Each student received an insufflator bulb and logbook to record otoscopic exams and completed an 18-item anonymous survey at clerkship conclusion. Results 115 of 150 students (77%) completed the survey. There was no significant difference in number of basic or pneumatic otoscopic exams performed based on method of training. Most students (68–72%) felt more likely to perform pneumatic otoscopy after training. Though the majority of students performed basic otoscopy on patients when an ear exam was indicated, they used pneumatic otoscopy less than 10% of the time. Students reported significant barriers to otoscopy: time, access to equipment, cerumen impaction, patient hold, and anxiety. Student comments described a culture where insufflation was neither practiced nor valued by supervising physicians. Conclusion Training in pneumatic otoscopy can increase student comfort, but barriers exist to using the skill in clinical practice
