Our objective was to test the hypothesis that internal medicine residents can be trained to screen for abdominal aortic aneurysm (AAA) using personal ultrasound imagers. We trained 5 randomly chosen internal medicine residents to image the abdominal aorta for patients with risk factors for AAAs using personal ultrasound imagers. Residents were trained in 3 or 4 one-on-one sessions with an instructor. To be eligible, patients had to be older than 65 years and have hypertension. After training, each of the 5 residents studied 3 patients independently. In 12 of the residents' 15 unsupervised studies, their abdominal aorta measurements were within 5 mm of the instructor's measurements with standard echocardiography (mean difference 3 mm, range 0-6 mm). Residents detected 3 previously unknown AAAs measuring 5.2, 4.2, and 3.9 cm in diameter. We conclude residents can be trained to image the abdominal aorta with personal ultrasound imagers and to identify AAAs in patients at risk.
可以培训内科住院医师使用个人超声成像仪筛查腹主动脉瘤（AAA）。我们随机挑选了5名内科住院医师，培训他们使用个人超声成像仪为有腹主动脉瘤风险因素的患者的腹主动脉成像。住院医师与一名教员进行3或4次一对一培训课程。符合条件的患者年龄必须超过65岁且患有高血压。培训后，5名住院医师每人独立研究3名患者。在住院医师的15次无监督研究中，有12次他们对腹主动脉的测量结果与教员使用标准超声心动图的测量结果相差在5毫米以内（平均差异3毫米，范围0至6毫米）。住院医师检测出3个此前未知的腹主动脉瘤，直径分别为5.2厘米、4.2厘米和3.9厘米。我们得出结论，住院医师可以接受培训，使用个人超声成像仪对腹主动脉进行成像，并识别有风险患者中的腹主动脉瘤。
