The Edinburgh Claudication Questionnaire has poor diagnostic accuracy in people with intermittent claudication.

ABSTRACT:

Background

The screening and diagnosis of intermittent claudication is a challenging process and often relies on the expertise of specialist vascular clinicians. We sought to investigate the diagnostic performance of the Edinburgh Claudication Questionnaire (ECQ) as a screening tool for referrals of suspected intermittent claudication from primary to secondary care.

Method

Results

The ECQ had a sensitivity of 46.8% (95% CI:
