Assessing the Diagnostic Accuracy of AUTOmated Ankle-Brachial Pressure Index Devices Across the Spectrum of Peripheral Arterial Disease (AUTO-PAD)- A Pilot Study
The aim of this pilot study is to investigate the diagnostic accuracy of two automated ABPI devices across the spectrum of PAD (asymptomatic PAD, suspected symptomatic PAD \[IC; including mild moderate and severe IC based on the Rutherford classification (21) and CLTI\] and post-bypass surveillance). A second aim is to assess their useability and tolerability through semi-structured interviews with patients and clinicians. This means the research will be split into two workstreams.
⁃ Group 1: Asymptomatic
• Adults aged 18 and over
• At risk of PAD with ≥1 cardiovascular risk factor
• No previous diagnosis of PAD
• English speaking and able to understand test protocols
⁃ Group 2a: Suspected PAD (intermittent claudication)
• Adults aged 18 and over
• Referred and booked into the nurse-led claudication clinic due to signs/symptoms in keeping with suspected intermittent claudication
• English speaking and able to understand test protocols
⁃ Group 2b: Suspected PAD (CLTI)
• Adults aged 18 and over
• Referred and booked into the vascular HOT clinic due to signs/symptoms in keeping with suspected CLTI
• English speaking and able to understand test protocols
⁃ Group 3: Post-bypass surveillance
• Adults aged 18 and over
• History of lower limb bypass surgery, enrolled in and attending the local surveillance programme
• English speaking and able to understand test protocols
