Ear, nose and throat problems are common in general practice, yet undergraduate and postgraduate teaching in the subject is variable and often sparse. The assumption that direct experience in otoscopy in practice will compensate for inadequate previous tuition was tested by assessing a group of 53 general practitioners and 59 medical students. Confidence in otoscopy was assessed using a visual analogue scale and skill was assessed by clinical examination of four ears. Otoscopy was divided into identifying the tympanic membrane, distinguishing a normal from an abnormal membrane and identifying specific features of the membrane. The medical students and general practitioners were comparable in both confidence and skill for all parameters except skill in identification of specific features of the tympanic membrane, in which the students' ability was greater (Student's t-test, P < 0.01). In both groups the percentage of false negative observations was reassuringly low--for students the mean was 3.0%; and for general practitioners 4.3%. There is room for improvement in general practitioner's training in otoscopy. Supervised tuition is essential and cannot be compensated for by unsupervised experience. More involvement with ear, nose and throat problems in vocational training or attendance at continuing education courses is suggested.
耳鼻喉问题在普通医疗实践中很常见,但该学科的本科和研究生教学参差不齐,且往往内容稀少。通过对53名全科医生和59名医学生进行评估,检验了这样一种假设,即实践中耳镜检查的直接经验将弥补先前教学不足的情况。使用视觉模拟量表评估耳镜检查的信心,并通过对四只耳朵进行临床检查来评估技能。耳镜检查分为识别鼓膜、区分正常与异常鼓膜以及识别鼓膜的特定特征。除了识别鼓膜特定特征的技能外,医学生和全科医生在所有参数的信心和技能方面都具有可比性,其中学生的能力更强(学生t检验,P<0.01)。两组的假阴性观察百分比都低得令人放心——学生的平均比例为3.0%;全科医生为4.3%。全科医生的耳镜检查培训仍有改进空间。有监督的教学至关重要,无监督的经验无法弥补。建议在职业培训中更多地涉及耳鼻喉问题,或参加继续教育课程。
