We examined the effectiveness of teaching ankle-brachial index (ABI) measurement to medical students. ABI was estimated in 28 lower limbs by an experienced vascular surgeon. After a 2-week training course, 5 fourth-year students repeated the estimations and their results were compared with that of the trainer's. There was no difference in ABI values between trainees and trainer for subjects with mild-to-moderate peripheral arterial disease (PAD; 0.77 ± 0.22 vs 0.77 ± 0.19, respectively, P = .95). In the 4 normal limbs, ABI was 1.37 ± 0.12 and 1.16 ± 0.11, as measured by the trainer and the trainees, respectively (P < .00001). In subjects with severe PAD, trainees tended to overestimate ABI (P = .0002) in the beginning of the educational process, but this was no longer the case at a later stage of the training with no difference in ABI values between the 2 examiner groups (P = .09). In conclusion, training of medical students in ABI measurement can be helpful toward accurate estimation of PAD and merits further practice.
我们研究了向医学生教授踝臂指数（ABI）测量方法的有效性。一位经验丰富的血管外科医生对28条下肢进行了ABI评估。经过为期2周的培训课程后，5名四年级学生重复了评估过程，并将他们的结果与培训师的结果进行了比较。对于轻度至中度外周动脉疾病（PAD）患者，受训者和培训师的ABI值没有差异（分别为0.77±0.22和0.77±0.19，P = 0.95）。在4条正常肢体中，培训师和受训者测量的ABI分别为1.37±0.12和1.16±0.11（P < 0.00001）。在重度PAD患者中，在教育过程开始时，受训者倾向于高估ABI（P = 0.0002），但在培训后期情况不再如此，两组检查者的ABI值没有差异（P = 0.09）。总之，对医学生进行ABI测量培训有助于准确评估PAD，值得进一步实践。
