BACKGROUND: Little is known about the characteristics and prognosis of patients with peripheral arterial disease (PAD) and related real-life health costs in France. METHODS: A cohort of patients diagnosed with PAD between 2007 and 2011 was extracted from the French Echantillon Généraliste des Bénéficiaires (EGB) claims database. The patients were followed up from the date of PAD diagnosis. Their characteristics, incidence of death and other events, treatments, and costs were analyzed by comparison with age- and gender-matched PAD-free controls. RESULTS: There were 5889 patients with PAD identified. Mean age was 70.8 years, and 68.1% of patients were male. Diabetes was present in 28.9% of patients (13.2% of controls), hypercholesterolemia in 52.9% (28.7%), and hypertension in 46.6% (12.3%); 4.9% of patients had a history of unstable angina or myocardial infarction (0.5%), and 6.0% had a history of stroke or transient ischemic attack (1.4%). At inclusion, 69.3% of patients were receiving antiplatelet drugs (17.3%), 52.3% statins (21.9%), 26.7% angiotensin-converting enzyme inhibitors (13.7%), and 24.2% angiotensin receptor blockers (16.6%). Cumulative mortality rates were 13.2% at 1 year and 19.4% at 2 years (3.2% and 6.5% in controls). Cumulative incidence rates of death and major cardiovascular events (myocardial infarction and ischemic stroke) were 15.7% (95% confidence interval [CI], 14.8%-16.6%) at 1 year and 22.9% (95% CI, 21.9%-24.0%) at 2 years vs 3.9% (95% CI, 3.4%-4.4%) and 7.8% (95% CI, 7.1%-8.5%) in controls. All differences were statistically significant (P < .05). Total annual management costs were €14,949 in the PAD group and €3812 in the control group. CONCLUSIONS: Mortality is elevated and cardiovascular events are frequent among French PAD patients. PAD drug treatment guidelines are not fully implemented in France.
