Assessing Knowledge and Attitude of Healthcare Professionals on Biosimilars: A National Survey for Pharmacists and Physicians in Taiwan.

Despite the first approval of biosimilars' in 2010, biosimilar products usage has remained low in Taiwan. This cross-sectional survey study assessed healthcare professionals' (HCPs)-hospital pharmacists, oncologists, and rheumatologists-knowledge, and attitudes toward biosimilars. More precisely, their knowledge and attitude towards biosimilars' current usage and regulations in Taiwan were analyzed. The mean ± standard deviation knowledge score was 2.56 ± 0.86 out of 4 ( = 395), and a difference in knowledge score was determined according to the hospital types ( = 0.004). Rheumatologists possessed significantly higher confidence in their knowledge of biosimilars than other HCPs ( = 0.001). Pharmacists showed the highest acceptance-and rheumatologists the least-for switching patients from reference drugs to biosimilars ( = 0.02). Hospital type was associated with the respondent's confidence in their knowledge ( = 0.04) and the preference for distinguishable naming of biosimilars ( = 0.007). Their knowledge scores were associated with their confidence in the efficacy and safety of biosimilars ( = 0.02). The study found that the current level of biosimilar knowledge of HCPs in Taiwan is low. The higher the knowledge score, the greater the confidence in biosimilars and the familiarity with relevant regulations.
