Abstract The
medical record management system is an important part of the hospital management system. The development of this system mainly includes the establishment of a back-end database and the development of front-end applications. For the former, it is required to establish a database with strong data consistency and integrity and good data security, while for the latter, it requires a complete and complete application function and a friendly and user-friendly operation interface. The system adopts modern office automation concepts, and is oriented to small and medium-sized hospitals, realizing paperless office, ensuring that medical units achieve efficient office and standardized management in the storage of medical records.
This paper mainly introduces the whole process of the design, development and realization of the pathology management system. The design process of the core module is explained in detail using functional structure diagram, database relation diagram and ER diagram. The overall medical record management system is based on the B/S (browser/server) model, the back-end database is SQL Server 2000, and the ASP embedded HTML language is used to design and implement. The cyclical process of medical records in custody is realized, and a series of medical record processes from patient registration to patient discharge are completed. Simplify the tedious manual operation, standardize the entire medical record processing process, and make the circulation of medical records more convenient and faster.

1 Introduction
1.1 Background of the subject In
recent years, with the continuous expansion of the scale of hospitals, it is no longer appropriate to use the original method of managing medical records only by people. At present, the information processing in hospitals in our country basically still stays in manual mode. The labor intensity is high and the work efficiency is low. A lot of time of medical staff and management personnel is consumed in transactional work; medical records, clinical examinations, pathological examinations and many other valuable data The retrieval of data is very laborious or even difficult to implement; in-depth statistical analysis of these data cannot be performed manually, and cannot be fully utilized for medical research.
With the increasing use of computers, the requirements for automation, informatization, and systemization of production management in all walks of life are also increasing; therefore, reducing labor intensity and improving labor efficiency will inevitably promote the use of electronic medical records in hospitals.
1.2 Current research status at home and abroad
Electronic medical records are a very complex project. Many countries in the world want to build health records, just to make medical records electronic. In the United States, due to the impact of the hurricane in New Orleans, there are roughly 500,000 to 600,000 medical files. These medical records are all on paper and kept in community clinics or regional hospitals. The medical files of these people are lost, including the local state. The government thought this was a huge accident. From this incident, we realized the urgency and importance of establishing electronic medical records, because the storage and utilization of electronic medical records would be safer. The federal government has also established a committee to establish electronic medical records, and put forward three basic principles. First, it is necessary to classify confidentiality. Some may be extremely confidential, and some may be shared by the public. This is the principle of security and privacy. Second, the fidelity of the update. There will be some changes in the static environment of the electronic medical record in the future, including clinical diagnosis and treatment. There should be records in this electronic medical record. At least you should know who made the diagnosis and what doctors made the changes under what circumstances. . Third, it must be quite convenient and easy for people to visit, and there must be no fortresses of some policies. As long as it is authorized, whether it is a professional physician or relevant parties, it should be able to obtain this medical record.
1.3 The significance of this research
Electronic medical records will improve the efficiency and quality of various work in the hospital, promote medical research and teaching; reduce the labor intensity of various business tasks, so that they can free up more energy and time to serve patients. Compared with paper medical records, the most significant advantage of electronic medical records is the sharing and repeated use of information and data. A patient does not need to bring a medical record to see a doctor, but only needs to provide his own name, medical record number or other information, and the doctor can obtain all the patient information through the computer. This system uses the B/S (Browser/Server) mode as the basic structure. All programs and data libraries are placed on the server. The browser only needs to install the operating system and browser. The system consists of two levels: user browser and Web server. The composition reflects the simplicity of its development and maintenance.
2 Analysis of the system development environment and technology
2.1 The main problems
that the system needs to solve The main target of the management system is the hospital, so in terms of system management, there should be different levels of management and medical staff and different permissions for different users. , The password administrator can add medical staff and modify the password of the added person, while the administrator can only modify his own password. In the medical record management page, the medical record administrator can view the medical record entry information of all medical staff, but cannot modify the entry information. Ordinary medical staff can log in to the system through the user name and password assigned by the administrator. They can see the management settings column but cannot operate due to the permission setting. The medical record information entered by the doctor can only be seen by oneself and can be modified. In the list, the medical record information entered by other doctors cannot be seen, which guarantees the patient's right to privacy.
After four months of work, I completed the basic functions of the medical record management system. After a trial, I basically met the needs of regular business. I realized online patient information management, patient information entry and other functions. The system performance is good, and it works normally. Strong portability, maintainability and safety. This system also has some unsatisfactory aspects, such as the security problem of the entered medical records that has not been well resolved, and some of the interfaces are relatively rough, which need to be improved in the future.
Through this graduation project, I fully realized the important connection between theory and practice. In the process of practice, I learned a lot of knowledge, have a better understanding of the application of the database, asp and html scripting language, the use of dreamweaver is also more proficient. At the same time, I have also discovered many deficiencies in myself, and I need to learn more, master and apply more knowledge in my future work.
