With reference to the content structure of CCR and information contents in the personal health record (PHR) systems in Apple App Store and in combination with relevant codes on health information, the paper defines the information classes and data items, and constructs an information model for PHR systems in the method of double-level modeling. Based on the corresponding relationship between the information model and data items, it generates standardized data of PHR systems, including 24 Level-1 information classes, 26 Level-2 information classes and 231 data items. It aims to provide a consistent data standard for different PHR systems in the process of information collection, recording and sharing, and provide a foundation for cross-platform transmission and sharing of data in PHR systems.
