Research On Information Integration Platform For Electronic Health Records Based On The Third Party

Huge progress was made in promoting medical and health informatization in our country in recent years, most hospitals have established the Hospital Information system or Electronic Health Records system.. As Internet grows and information technologies matures,the construction of informatization will be steadily deepened.An overall integrating the resources of medical and health,eliminating Information Isolated Island, the share of regional information resources is an inevitable trend.This paper summarized approaches of information integration of Regional Electronic Patient Records in foreign countries on the basis of a thorough knowledge of the present conditions of study on Regional Electronic Patient Records both at home and abroad, Integrating with current situation of the expression format of healthcare information different, the hospital system from different system developers was a school unto himself.therefore , the information exchange and information sharing among different hospitals is difficult. We proposed the approach of data centre which government as the third party to integrate hospital information in the region,and to build digital medical platform which Conforming to one standard and share medical data among objects.This thesis made a deep study of the HL7 clinical document architecture (CDA) specifications in key areas,also, Integrating with the existing medical information standards in our country and demand for localization,we have made localisation customization to CDA R2.0 specifications,and the information models are applied to the standardize the format of EPR documents.Firstly, we built unified data structure in the data centre of the third party to integrate different structure data from various hospitals in the region,and achieved information transmission from hospital to the third party by using Web Services technology based on XML specifications. In this way,we integrated various hospital's information system or Electronic Patient Records system while keeping hospital system autonomy.Secondly,CDA standard documents are created by using DOM technique and stored in the XML Electronic Patient Records database for document retrieval.finally,we built the website of centre of Electronic Patient Records and Electronic Patient Records bi-directional referral system, provided interface of information exchange and sharin, facilitates the sharing of information centered on the third party in the region. The EPR information exchange and sharing among hospitals is feasible by building the regional Electronic Patient Records center.
