However, they can be inaccurate and have limited utility in patients with incompressible arteries, lower limb wounds and\/or lack of digits. This study aims to evaluate BlueDop, a novel device that purports to assess peripheral perfusion without the need for a lower limb tourniquet or patients lying flat.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n Patients attending vascular and podiatry clinic at Aneurin Bevan University Health Board were recruited between May 2022 and May 2023. A BlueDop reading was recorded in addition to ankle and\/or toe brachial pressure index. Satisfaction and preference of each method was recorded using an electronic proforma.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n 176 patients were included. BlueDop ABPI was shown to be moderately correlated with cuff-ABPI (r\n s<\/jats:sub>\n = 0.42,\n p<\/jats:italic>\n = .001) and weakly correlated with TBPI (r\n s<\/jats:sub>\n = 0.22,\n p<\/jats:italic>\n = .04). BlueDop had moderate accuracy in diagnosing PAD (C statistic = 0.653) and was more accurate in diagnosing severe PAD (C statistic = 0.706). Diagnostic accuracy appeared to be improved when PAD was defined according to cuff-ABPI only. Patients were more satisfied with BlueDop (mean satisfaction score (MSS) = 4.33) compared to cuff-ABPI (MSS = 2.89, mean difference = 0.544,\n p<\/jats:italic>\n < .001) and TBPI (MSS = 3.82, mean difference = 0.579,\n p<\/jats:italic>\n < .001) while operator satisfaction was equal.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n There is moderate correlation between BlueDop and cuff-ABPI. Patients prefer BlueDop to cuff-ABPI or TBPI. BlueDop appears to be an acceptable method of non-invasive assessment of PAD, although users must appreciate there is a discrepancy between it and cuff-ABPI\/TBPI.<\/jats:p>\n <\/jats:sec>","DOI":"10.1177\/17085381251359309","type":"journal-article","created":{"date-parts":[[2025,7,30]],"date-time":"2025-07-30T20:23:40Z","timestamp":1753907020000},"page":"612-619","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Can BlueDop be used as an alternative for diagnosing peripheral arterial disease?
