Abstract: With the development of computer technology, the electronic medical record system is becoming more and more perfect, which has a far-reaching influence on the construction of hospital information system. In the construction process of electronic medical record system, rapid and accurate collection of medical record information has been realized gradually, but the application of electronic medical record data is still in the initial stage. Based on electronic medical records, the status quo of the application data quality of data entry, structural elements, statistical technology is analyzed, and according to current situation of electronic medical records, medical record data application countermeasures, combining the information technology development, the future use of artificial intelligence, cloud computing, big data, such as technology, visions and electronic medical records electronic medical record system application data content and thinking.
