The sensitivity and specificity of the toe brachial index in detecting peripheral arterial disease
Peripheral arterial disease (PAD) is reported to affect up to 12% of the adult population and has significant health ramifications. PAD is associated with delayed wound healing and amputation. Podiatric vascular assessment plays an important part of identifying PAD. Traditionally, ankle brachial indices (ABI) have been used as a screening tool for non-invasive assessment of PAD however recent evidence has suggested that in certain populations there may be a decrease in the ABI’s sensitivity and specificity. The toe brachial index (TBI) has been suggested as potentially a more reliable indicator of the presence of PAD however, there is limited evidence currently on the validity of the TBI.
Participants were recruited from a Private Vascular Clinic, and a Community Health Centre Podiatry Service. ABI and TBI’s were performed on all participants. Colour duplex ultrasound (CDU) was used to determine the presence or absence of PAD. Diagnostic accuracy of ABI and TBI results
