HIS与社会医疗保险系统接口的设计与实现

The design and implementation of interface software between HIS and MIS of social medical insurance

HIS与社会医疗保险系统接口的功能是支持2个系统间的数据交换,实现HIS的医保管理功能。系统采用实时交易模式,上端接口为动态连接库形式。下端接口的设计工作分3部分:在HIS数据库中建立医保项目和HIS项目的对照;在HIS数据库中为医保特定的信息设计数据结构;开发医保管理业务模块并改造与医保有关的HIS业务模块。程序设计的关键在于对动态连接库中函数的适当调用,正确构造发送参数字符串和分解返回参数字符串。

The interface software between HIS and MIS of social medical insurance makes it possible to interchange data between the two systems and apply HIS to medical insurance management. Usually, the social medical insurance center offers a standard method of interface, which is called the upper interface. The interface between the upper interface and HIS, called the lower interface, requires specific design based on specific HIS. This article discusses a case in which a HIS client computer can transmit data to the server at the insurance center and receive real-time processing results. The upper interface consists of two dynamic link libraries (DLL). Three tasks have to be accomplished to program the lower interface, which are to create a table in HIS database and arrange every item in HIS price list with its corresponding item in the insurance list, to create tables or fields in HIS database to store proper data for medical insurance business, and to design a special HIS application module and alter several existing modules for medical insurance business. There are some key points in programming such as invoking a function in the DLL properly, gathering data to form a character storing variables for the function and parsing the returned character string to extract result data.
