The Ankle-Brachial Pressure Index (ABPI) is the easiest non-invasive method for the assessment of peripheral arterial diseases (PAD) but remains uncommon in general practice, because of the need for training and specific devices. The purpose of this survey was to assess the reliability of the automated oscillometric measurement of the ABPI, compared with the gold-standard Doppler ultrasound measurement.
A study was conducted on patients aged 65 years and over without diagnosed PAD hospitalized in the Teaching Hospital of Angers (France) from July 2008 to March 2009. In compressive ankle arteries and atrial fibrillation were exclusion criteria. ABPI measurements were performed by the same examiner with oscillometric and Doppler devices. Reproducibility was assessed by the intra-class correlation coefficient of agreement (ICC) and the Bland-Altman method.
Out of the 287 eligible hospitalized patients, 221 patients were included in the study and 56 (25%) had an ABPI below 0.90. The inter-method reliability is poor (ICC = 0.35+/-0.08) and the mean difference between the methods was 0.08+/-0.26 according to the Bland-Altman method.
Automatic oscillometric devices cannot be recommended as a reliable alternative to access the ABPI.
踝臂指数（ABPI）是评估外周动脉疾病（PAD）最简单的非侵入性方法，但由于需要培训和特定设备，在一般医疗实践中并不常见。本调查的目的是评估与金标准多普勒超声测量相比，自动示波法测量ABPI的可靠性。
对2008年7月至2009年3月在法国昂热教学医院住院的65岁及以上未诊断为PAD的患者进行了一项研究。排除标准为压迫性踝动脉和心房颤动。ABPI测量由同一名检查者使用示波装置和多普勒装置进行。通过组内相关系数（ICC）和布兰德-奥特曼方法评估再现性。
在287名符合条件的住院患者中，221名患者纳入研究，56名（25%）患者的ABPI低于0.90。方法间的可靠性较差（ICC = 0.
