Inadequate Health Literacy in Patients with Arterial Vascular Disease

Objective The aim was to identify the prevalence of inadequate health literacy in patients with arterial vascular disease. This was a cross sectional study. Methods Patients with arterial vascular disease visiting the outpatient clinic between January 5, 2015 and December 28, 2016, were randomly included and screened for inadequate health literacy with the Newest Vital Sign–Dutch (NVS-D), a validated health literacy assessment measure. A score of t -test or the Mann–Whitney U test and chi-square test. Logistic regression with backward elimination was applied to identify independent predictors. Results A total of 202 patients were included. The mean NVS-D score was 1.91 (SD ± 1.948, median 1). The prevalence of inadequate health literacy was 76.7%. A significantly higher prevalence of inadequate health literacy was found in patients ≥65 years ( p p p  = .056), nor between participants with peripheral arterial occlusive disease and abdominal aortic aneurysm ( p  = .116). Age (OR 1.060; 95% CI 1.017–1.104; p  = .005) and education level (OR 0.164; 95% CI 0.078–0.346; p Conclusion This study shows a prevalence of inadequate health literacy of 76.7% in patients with arterial vascular disease, with a significantly higher prevalence in patients ≥ 65 years and patients with a lower education level. The high prevalence of inadequate health literacy should be considered when information is provided, and suggests the need to further investigate the best methods to convey medical information to this group of vulnerable patients.
