Assessment of the Literacy Level of Patients With Chronic Rheumatic Diseases and Association With the Level of Knowledge and Medication Adherence: For a Better Integration of Patients' Literacy Levels Into Their Therapeutic Management.

A medication non-adherence is reported in chronic rheumatic diseases, in a context of complex and long-term treatments (injectable/per os targeted therapies, biosimilar...). Understanding and integrating the patient into a shared medical decision are key factors for adherence. From this perspective, the level of literacy (an individual's ability to find, understand and use health information) must be explored in order to adapt the communication of information. These are currently insufficiently adapted to the individual understanding of patients. In practice, literacy assessment is very poorly integrated into routine care, while several tools are validated in French. In rheumatology, foreign studies have shown that literacy is positively related to knowledge level. The results remain contradictory regarding its association with medication adherence. Today, the literacy level of patients with rheumatic diseases and its impact on adherence has not been studied in France, although these evaluations would be useful to adapt interventions individually. The acceptance of patients to complete a literacy assessment questionnaire during their care should also be analysed as a condition of its deployment.
