Results In the past three years， both the number of public and private medical institutions specializing in plastic and aesthetic major has shown an upward trend. The number of doctors increased significantly in 2022， with over 90% of doctors in public institutions (about 70% in private institutions) receiving higher education. In recent years， the proportion of doctors from other specialties engaging in plastic and aesthetic activities has increased. The proportion of inpatients seeking aesthetic treatments has also increased. Among outpatient patients， the proportion of injection procedures is relatively low. About one-third of private medical institutions have not yet adopted an electronic medical record system. Conclusion Data feedback is the cornerstone of medical quality control in Chinese plastic and aesthetic major. Existing data indicates that the industry is developing steadily， but there is still room for improvement in some indicator data. However， due to the limited data from private medical institutions， it is still necessary to encourage them to improve their reporting enthusiasm in order to conduct a more comprehensive assessment in the future.
