Background: We tested a screening algorithm of lower extremity arterial disease (LEAD)
for general practitioners (GPs) with a 1-year follow-up examination. Besides, patients
were referred for vascular specialists to verify the presence of LEAD with specific
tools. Method: 327 patients were followed-up. We recorded the differences in the anamnesis.
Ankle brachial index was re-measured. Patients repeated walking-test. We compared
our results to the specialist control. Results: Specialists confirmed LEAD in 73.7%.
63.1% reported IC symptoms. Our screening algorithm had a sensitivity of 92%, and
a specificity of 96%, positive and negative predictive values were 91% and 96%. Most
LEAD-positive patients received LEAD-specific medications (94.2%) and antiplatelet
therapy (91.7%). Improvement in walking test were shown in 96 cases (29.3%). Conclusion:
Our screening algorithm combined with specialist control has proven to be an easy-to-apply,
and efficient methodology for GPs with excellent sensitivity and specificity in identifying
individuals at risk of LEAD.
