The rise of internet thinking, along with the growing acceptance of the " patient-centered" concept, has played a significant role in driving the development of electronic patient-reported outcomes (ePROs) in the field of clinical evaluation. While several large-scale and well-established ePROs evaluation systems have been widely adopted and implemented worldwide, China has lagged behind in ePROs research and electronic application. Therefore, the purpose of this paper is to comprehensively analyze and summarize the concepts, types, characteristics, state of development, and application of ePROs. Specifically, it focuses on analyzing the structure and content of ePROs evaluation network systems in the United States, France, and the United Kingdom. The ultimate objective is to provide insightful analysis and useful suggestions to aid in the development and evolution of ePROs in China.
