To determine medical student preferences for learning the ocular fundus examination and to assess their accuracy using different examination modalities.
Prospective, randomized study of medical student education approaches.
First-year medical students received training in direct ophthalmoscopy using simulators and human volunteers. Students were randomized to receive vs not receive specific training on interpreting fundus photographs prior to accuracy assessments. Students' preferences for each of the 3 methods (direct ophthalmoscopy on simulators or human volunteers, or use of fundus photographs) and recognition of normal and abnormal fundus features were assessed.
Of 138 first-year medical students, 119 (86%) completed all required elements. For learning ophthalmoscopy, 85 (71%) preferred humans to simulators. For learning relevant features of the ocular fundus, 92 (77%) preferred photographs to ophthalmoscopy on simulators or humans. Accuracy of answers was better when interpreting fundus photographs than when performing ophthalmoscopy on simulators (P < .001). Performance improved after specific teaching about assessing fundus photographs before testing (P = .02). Examination of the ocular fundus was found easier and less frustrating when using photographs than when using ophthalmoscopy on simulators or humans. Eighty-four students (70%) said they would prefer to have fundus photographs instead of using the ophthalmoscope during upcoming clinical rotations.
Students preferred fundus photographs for both learning and examining the ocular fundus. Identification of ocular fundus features was more accurate on photographs compared to examination by direct ophthalmoscopy. In the future, the increasing availability of nonmydriatic ocular fundus photography may allow replacement of direct ophthalmoscopy in many clinical settings for non-ophthalmologists.
确定医学生对学习眼底检查的偏好,并评估他们使用不同检查方式的准确性。
医学生教育方法的前瞻性、随机研究。
对一年级医学生进行眼底镜检查的模拟和志愿者直接检查培训。学生被随机分为接受或不接受特定的眼底照片解读培训,然后进行准确性评估。评估学生对这 3 种方法(眼底镜直接检查模拟或志愿者、或使用眼底照片)的偏好以及对正常和异常眼底特征的识别。
在 138 名一年级医学生中,有 119 名(86%)完成了所有必需的内容。在学习眼底镜检查方面,85 名(71%)学生更喜欢用人眼而不是模拟器。在学习眼底相关特征方面,92 名(77%)学生更喜欢照片而不是眼底镜直接检查。与在模拟器上进行眼底镜检查相比,解释眼底照片的答案准确性更高(P <.001)。在测试前进行专门的眼底照片评估教学后,准确性提高(P =.02)。与使用眼底镜直接检查模拟或志愿者相比,使用照片进行眼底检查被认为更容易且不那么令人沮丧。84 名学生(70%)表示,他们在即将到来的临床轮转中更愿意使用眼底照片而不是眼底镜。
学生更喜欢使用眼底照片进行学习和检查眼底。与直接眼底镜检查相比,眼底照片在识别眼底特征方面更准确。在未来,随着非散瞳眼底摄影的日益普及,非眼科医生在许多临床环境中可能会取代直接眼底镜检查。
