Implication

May support toe oximetry as PAD screening adjunct in asymptomatic diabetes; hypothesis-generating and should not yet change practice.

Structured PICO

Does pulse oximetry accurately diagnose lower extremity arterial disease in asymptomatic patients with type 2 diabetes mellitus?

Population

57 consecutive outpatients with type 2 diabetes who had no symptoms of lower extremity arterial disease (LEAD), in a primary care setting. Exclusions: age younger than 40 years, known LEAD, or typical symptoms of LEAD.

Intervention

Pulse oximetry of the toes (abnormal if Sao2 >2% lower from finger or on 12-in elevation of foot), Ankle-Brachial Index (ABI) (abnormal if <0.9), and the combination of the two.

Comparator

Doppler waveform analysis of the lower extremity arteries (LEAD defined as monophasic waveforms).

Outcome

Diagnostic accuracy (sensitivity, specificity, and likelihood ratios) for lower extremity arterial disease.surrogate

Pulse oximetry of the toes is as accurate as the ankle-brachial index for screening lower extremity arterial disease in asymptomatic patients with type 2 diabetes, and combining the two tests increases sensitivity.
