Samenvatting

OBJECTIVES: Peripheral artery disease (PAD) is a global disease. Understanding variability in patient profiles and PAD-specific health status outcomes across health system countries can provide insights into improving PAD care. We compared these features between 2 high-income countries, the United States (US) and the Netherlands.

MATERIALS AND METHODS: Patients were identified from the Patient-centered Outcomes Related to Treatment Practices in Peripheral Arterial Disease: Investigating Trajectories (PORTRAIT) study - a prospective, international registry of patients presenting to vascular specialty clinics for new onset, or exacerbation of PAD symptoms. PAD-specific health status was measured with the Peripheral Artery Questionnaire (PAQ). General linear mixed models for repeated measures were used to study baseline, 3-, 6-, and 12-month PAD-specific health status outcomes (PAQ summary score) between US and the Netherlands.

RESULTS: Out of a total of 1,114 patients, 748 patients (67.1%) were from the US and 366 (32.9%) from the Netherlands. US patients with PAD were older, with more financial barriers, higher cardiovascular risk factor burden, and lower referral rates for exercise treatment (p < 0.001). They had significantly worse PAD-specific adjusted health status scores at presentation, 3-, 6- and 12 months of follow-up (all p < 0.0001). Magnitude of change in 1-year health status scores was smaller in the US cohort as compared with the Netherlands.

CONCLUSION: Compared with the Dutch cohort, US patients had worse adjusted PAD-specific health status scores at all time point, improving less over time, despite treatment. Leveraging inter-country differences in care and outcomes could provide important insights into optimizing PAD outcomes.
