Abstract:
Objective To explore the data consistency guarantee of different systems based on integrated platform,to find the preferred guarantee scheme for different systems,and to ensure the quality of data while ensuring the healthy operation of the business system.Methods The master patient index information register was decrypted by means of message intermediate table so as to ensure asynchronous data generated by the consistency of the data.Message retransmission and the self-detection function of master index information register were used to ensure the consistency of the main index information.Through a combination of methods with real-time message reception and difference data ETL extraction the consistency of data for hospital data repository was realized.In view of the consistency of business system data,the consistency of business data was implemented through the message check,transaction control,emergency protection and etc.Results The number of the master patient index reached 7.97 million,the registered patient increased by 1 300 man-time daily,and the data quantity rose by 1.2 million pieces daily in the data center.One-year trial proved the stability of all the business systems and the accuracy of the data.Conclusion Data consistency schemes are developed according to the business scenarios and data characteristics of the master patient index system,data center and business systems,which enhance the efficiency of the integrated platform while raising data reliability,and are worthy promoting practically.
