New Zealand Study Reveals Importance of Patient Attitudes Toward Biosimilars

April 25, 2020

Patients who research medical information online are likely to be more concerned about switching from originator products to biosimilars, according to the study.

A New Zealand study of patients with rheumatic conditions suggests that providers need to be mindful of patient attitudes toward biosimilars to prevent biased therapy choices and poor outcomes.

Patients who do online searching for medical information about biosimilars are liable to have exacerbated concerns about switching to biosimilars, according to the study, which examined patient attitudes toward these agents. The findings also indicated that women are more likely to have concerns about switching from originator drugs to biosimilars.

Among the findings:

  • There was a positive correlation between adverse events experiences from the originator and adverse events anticipated from the biosimilar (P < .001.
  • There was a positive association between perceptions of originator safety and the expectation that biosimilars are unsafe (P <.001).
  • There was a significant negative association between the perceived effectiveness of the current originator and a preference for a biosimilar medicine (P <.001).
