COLL-BEY, Sara; LOPEZ-CASANOVA, Pablo; VERDU-SORIANO, José  and  BERENGUER-PEREZ, Miriam. Reliability of automated methods in determining the ankle-brachial index. Systematic review. Gerokomos [online]. 2022, vol.33, n.2, pp.119-126.  Epub Oct 24, 2022. ISSN 1134-928X.

Peripheral artery disease is one of the main factors involved in the onset of ischemic etiology ulcers of the lower limb in patients older than 70 years old. The appearance of this disease leads to an increase in the morbidity and mortality and even affects the quality of life of the person who suffers from this disease. All this makes it necessary to apply diagnostic methods to make an early diagnosis. To this end, an initial clinical examination and a hemodynamic examination are carried out by calculating the ankle-brachial index (ABI). The method that is considered the gold standard is the Doppler technique. However, the time involved in its implementation and the need for prior training has hampered its practice in primary care. As a solution to this, automatic oscillometric devices that measure blood pressure have been proposed to replace the traditional method. In order to determine the reliability of automatic devices when it comes to determining the ankle-brachial index, a systematic review of scientific literature databases has been performed: MEDLINE, SciELO, Cochrane, Elsevier and CUIDEN until February 2020. A total of 58 items were received, 15 of which were included for the analysis. Several published results are due to the different methodologies employed, profiles of patients selected for the study and various models of oscillometry studied in each article. Therefore, the differences found in the articles make it difficult to make a fair comparison between them in order to determine which device would be the most reliable in determining the ankle-brachial index compared to the Doppler technique; recommending the continuous designfocused research in order to establish an effective alternative to the traditional method in clinical practice.
