Objective Evaluation of Otoscopy Skills Among Family and Community Medicine, Pediatric, and Otolaryngology Residents

IntroductionThe objective of this study is to evaluate and compare the perceived need for otolaryngology training and otoscopy diagnostic skills in primary care (Family and Community Medicine, Pediatric Medicine), and Otolaryngology Head and Neck Surgery (OTO-HNS) postgraduate trainees. Participant otoscopy skills were evaluated using the OtoSim simulator.MethodsFamily and Community Medicine, Pediatric, and OTO-HNS residents were recruited. Each resident participated in 3 separate otoscopy training and assessment sessions. The ability to correctly identify middle ear pathology was objectively evaluated using OtoSim™. Pretest, posttest, and 3-month retention test results were compared among residents in a paired comparison paradigm. Survey data assessing exposure to OTO-HNS during undergraduate and postgraduate training were also collected.ResultsA total of 57 residents participated in the study. All residents reported limited exposure to OTO-HNS during undergraduate medical training. Primary care trainees performed poorly on pretest assessments (30% ± 7.8%; 95% CI). Significant improvement in diagnostic accuracy was demonstrated following a single 1-hour teaching session (30%-62%; p < 0.001). Primary care residents demonstrated a significant decrease in diagnostic accuracy at a 3-month follow-up assessment (62%-52%, p < 0.001). Self-perceived comfort with otology was poorly correlated to pretest performance among primary care trainees (r = 0.26) and showed a stronger positive correlation among OTO-HNS trainees (r = 0.56).ConclusionsA single teaching session with an otoscopy simulator significantly improved diagnostic accuracy in primary care and OTO-HNS trainees. Improved performance is susceptible to deterioration at 3 months if acquired skills are not frequently used. Self-perceived comfort with otology may not be an accurate predictor of otoscopic diagnostic skill.
