Comparative Diagnostic Accuracy Study of Bedside Tests Used to Detect Arterial Disease in Diabetes:
In Brief
An observational study evaluating Transcutaneous pressure of oxygen (TcPO2), Toe Brachial Pressure Index (TBPI), and 3 other interventions for Diabetic Foot and 6 related conditions. Completed, enrolled 305 participants across 2 sites.
Detailed Summary
This study will focus on determining; * How accurate the test is in detecting poor circulation * How it's accuracy compares to other commonly used tests, and * Whether test results are linked to the chance of ulcer healing or amputation. Across 2 hospitals, 305 diabetic patients will be scanned using the focused ultrasound test as well as other commonly used tests to detect poor circulation. Their results will be compared to a full version of the ultrasound test to identify the most accurate.
Study Details
Timeline
Interventions
Measurements will be taken from the dorsum of the foot using an automated machine equipped with Clark electrodes.
TBPI will be measured using the photoplethysmography (PPG) method, employing an infrared sensor placed on the hallux and index finger.
Podiatry ankle duplex scan (PAD-scan) involves using an ultrasound machine to visualise the anterior and posterior tibial arteries at the ankle.
Continuous Doppler device which gives visual display of arterial spectral waveform at the ankle.
A sphygmomanometer-cuff placed at the ankle and a handheld continuous wave Doppler device will be used to measure the systolic pressure of the DPA and PTA.
