ABSTRACT

OBJECTIVE: To determine the degree of knowledge about biological therapy and biosimilars in patients with immune-mediated inflammatory diseases treated in Outpatient Pharmaceutical Care Units. METHODS: Observational, prospective and multicenter study during the period May 2020-March 2021. A survey (9 questions) was conducted before starting treatment in which the patients' level of knowledge about biological therapy and biosimilars was assessed. RESULTS: A total of 169 patients were included in the study. The average value for the different questions was 3.3 ± 0.6 out of 5, while the average final result was 29.4 points out of 45. Sixty-four percent of the patients had an acceptable level before starting the medication (>27 points). The multivariate analysis showed a statistically significant correlation (p<0.05) with a better score at the beginning of treatment in those patients whose prescribing service was Rheumatology. CONCLUSIONS: In general, the level of knowledge prior to biological therapy in patients is acceptable, being higher in dosage and administration technique related-factors and what is related to the dosage and administration technique and where to find information related to the medication; the worst rated were those on biosimilars-related. The factor of being followed by rheumatology, was associated with better knowledge.
