Objective: The paper analyzes the current situation of the circulation of medical insurance data elements and proposes suggestions to promote circulation. Methods: The paper analyzes experience of the United States, the United Kingdom, Germany, and Singapore and domestic developments, and focuses on the balance of data security and value release. Results: Internationally, medical insurance data elements keep data openness, standardization, and security technology as the core. At home, a national unified medical insurance information platform has been established, but it faces challenges such as cross-section sharing and security protection. Conclusion: It is suggested to build a trusted data element space for medical insurance, and promote local pilots, cross-section collaboration, and socialized services to achieve secure and efficient data circulation.
