Physicians’ perceptions of generic drugs in China

Background: In recent years, there has been a significant worldwide increase in the use of generic drugs. China has committed to a consistency evaluation of generic drugs, with the aim to improve the rate of substitution. However, there is little research on physicians' perceptions of generic drugs in China. Objective: The study aimed to explore the perceptions of physicians in China toward generic drugs. Methods: Perceptions of Chinese physicians towards generic drugs were evaluated by a cross-sectional study from June to July 2020. The online survey tool Sojump was adopted to distribute the questionnaires using convenience sampling. A total of 598 questionnaires were analyzed. Results: Perceptions of Chinese physicians towards generic drugs are generally positive. However, not all physicians appear to have sufficient knowledge about generic drugs and some of them expressed negative perceptions of generic drugs, such as perceiving generic drugs as less effective and more likely to cause side effects compared to brand-name drugs. There were significant differences in physicians' opinions about generic drugs according to age group, years in practice, educational background, clinical specialty and residential area. Conclusion: It is imperative to provide physicians with more extensive education about the consistency evaluation of generic drugs to meet the policy goal of reducing overall national medical healthcare costs.
