Educating patients about biosimilars seems important to increase the prescription rate of biosimilars. This study aimed to evaluate the impact of a clinical pharmacist consultation on the switch to and retention rate of a biosimilar for patients with inflammatory rheumatic diseases. This retrospective study compared 2 groups of adult patients receiving (intervention) or not (control) a consultation with a pharmacist right before the rheumatologist consultation. The primary outcome was the frequency of patients who switched to a biosimilar at the end of the rheumatologist visit. We analysed 141 patients (50% women, 50±15years old, on original adalimumab (62%) or etanercept (38%)) who had never used biosimilars: 85 in the intervention group and 56 in the control group. The switch rate to a biosimilar significantly differed between the groups: 69.4% versus 41.1% in the intervention group versus the control group respectively (P This study highlights the positive impact of a pharmacist consultation before the physician's one on switching to a biosimilar, but more studies are needed to assess the impact of this pharmacist consultation on preventing the nocebo effect and therefore on improving the retention rate of biosimilars.
