Health literacy is the ability to access, understand, evaluate and apply information in order to communicate with health professionals and understand health instructions but also, promote, maintain and improve health throughout life. Health literacy (HL) is known as a health determinant.

An association has been shown between low HL and poorer health outcomes such as increased number of unscheduled hospitalisation or emergency visits, low medication adherence and poor health status.

These have been particularly demonstrated with cardiovascular diseases, which combine risk factors (emergency hospitalization, reduction in the length of hospital stays, and complex secondary preventive drug treatments). Despite large scientific international literature about HL and health outcomes, no information is available in France on the prevalence of low HL level among patients managed for neuro-cardio-vascular diseases.

It has been shown in other countries that healthcare professionals overestimate the HL level of their patients and do not adapt information to the HL level. Therefore, patients with low HL do not understand and/or are not able to use properly the information they receive.

Having a better knowledge of HL level and characteristics in these patients is necessary to develop tools for helping healthcare professionals to identify patients with low HL level and to realize the role of HL as a determinant of health. It will also provide more precise information on the difficulties or needs of patients with different levels of health literacy.
