Patient satisfaction survey: substitution of reference etanercept with a biosimilar product.

Objectives: To assess patient satisfaction after pharmacy-mediated replacement of the originator etanercept prefilled syringe with its biosimilar prefilled pen.

Methods: Prospective observational study from March to May 2018, to assess satisfaction with the new drug dispensed. Patients were asked to answer a paper questionnaire with three questions: pain at injection site, ease of administration, and overall patient satisfaction with the change, rated on a scale from 1 (not satisfied) to 5 (extremely satisfied).
