There is a lack of knowledge among patients concerning their treatment with bDMARDs. To increase knowledge and safety skills, patient education is essential.

The aim of this study is to assess the impact of a pharmacist's educational interview on on knowledge and safety skills to bDMARDs in patients with inflammatory arthritis.

This is an observational, controlled, open-label and monocentric study. 60 patients are planned to be included.

Knowledge are assessed three time by self-administered questionnaire:

at baseline before the pharmacist's educational interview at three months apart at six months apart

One primary end-point is defined:

the changes from baseline to M3 and M6 in the patients' knowledge score about subcutaneous bDMARD management (self-administered questionnaire, Biosecure)

As secondary end-points, the changes from baseline to M3 and M6 in patients' adherence, patients' satisfaction regarding the pharmacists' intervention and the effect of the interview on rate of patients treated by biosimilar are evaluated.
