Impact of Behavioral Factors on Treatment Adherence in a Sample of Rheumatoid Arthritis Patients

Rheumatoid arthritis (RA) care has been revolutionized in the last decade with the advent of biotherapies. The success of this therapeutic strategy is based on several factors, including the medication adherence. Whatever the method used, adherence evaluation is not sufficient, around 66% of the treated patients. Nevertheless, studies analysing the predictive factors of medication adherence in RA are rare.

RA patients are also educated about the infectious risk related to RA and treatments, and the importance of vaccination. These recommendations are not always respected by the patients, without knowing the exact factors leading to this decision. Furthermore, a lot of patients take personal initiatives without the agreement and the help of their practitioner, like diets or special feeding behaviors. Lastly, plenty of patients affected bv chronic diseases claim and use electronic health tools without any real evidence of the efficacy of such device.

The aim of this study is thus to evaluate RA treatment adherence considering demographic data, vaccination coverage, feeding behavior and the use of e-health tools.
