Abstract/OtherAbstract:
Relatively little is known on how the Doppler method compares with oscillometric measurement using a conventional automatic blood pressure device to determine the ankle-brachial index, when determinations are performed by physicians with little experience. To assess the diagnostic efficacy of both methods in this professional group, we calculated their sensitivity, specificity, and positive and negative predictive value in 158 legs of 85 patients with symptoms of intermittent claudication. Angiography was used as the gold standard. Of the legs examined, 131 showed significant arterial obstruction. The oscillometric method showed 97% sensitivity, 89% specificity, 98% positive predictive value, and 86% negative predictive value. The Doppler method showed 95% sensitivity, 56% specificity, 91% positive predictive value, and 68% negative predictive value. This study suggests that the automatic blood pressure equipment has greater diagnostic accuracy when the test is performed by physicians not specifically trained to use the Doppler probe.
