OBJECTIVE: To determine the accuracy of audible arterial foot signals with an
audible handheld Doppler ultrasound for identification of significant peripheral
arterial disease as a simple, quick, and readily available bedside screening
tool.
METHODS: Two hundred consecutive patients referred to an interprofessional wound
care clinic underwent audible handheld Doppler ultrasound of both legs. As a
control and comparator, a formal bilateral lower leg vascular study including the
calculation of Ankle Brachial Pressure Index and toe pressure (TP) was performed
at the vascular lab. Diagnostic reliability of audible handheld Doppler
ultrasound was calculated versus Ankle Brachial Pressure Index as the gold
standard test.
RESULTS: A sensitivity of 42.8%, a specificity of 97.5%, negative predictive
value of 94.10%, positive predictive value of 65.22%, positive likelihood ratio
of 17.52, and negative likelihood ratio of 0.59. The univariable logistic
regression model had an area under the curve of 0.78. There was a statistically
significant difference at the 5% level between univariable and multivariable area
under the curves of the dorsalis pedis and posterior tibial models (p < 0.001).
CONCLUSION: Audible handheld Doppler ultrasound proved to be a reliable, simple,
rapid, and inexpensive bedside exclusion test of peripheral arterial disease in
diabetic and nondiabetic patients.
