The potential role of oscillometric devices for ankle-brachial index measurements in clinical practice

Abstract

Oscillometric devices in contrast to the traditional Doppler based method for ankle-brachial index measurements have promising advantages like no need for special training, faster performance, and operator independence. Comparative assessment of the oscillometric and Doppler-based ankle-brachial index measurement. Ankle-brachial index measurements were performed by continuous wave Doppler and an automatic oscillometric device (BOSO ABI-system 100) in consecutive subjects. The comparative assessment was performed by Bland-Altman and ROC analysis. The two kinds of measurements (734 measurements) showed a good agreement in the ankle-brachial index spectrum close to the cut-off value of 0.9. The agreement diminished below or above this value. The optimal oscillometric ankle-brachial index diagnostic cut-off value was 0.96. The oscillometric device is not interchangeable for Doppler devices in the whole ankle-brachial index spectrum. Nevertheless, owing to its discriminative power, the oscillometric measurement potentially has an efficient role in the screening of asymptomatic patients. Orv Hetil. 2018; 159(5): 176-182.
