Methods With reference to results and experience of the domestic and foreign research and by virtualizing re-establish-ment of the existing medical information resources,a regional medical information sharing platform was established based on cloud computing, SOA,and Web services, and then the heterogeneous information systems in different medical institutions were integrated.Results A novel cloud platform solution was proposed for clinical information exchange between medical institutions based on Web services that exchanged data and ensured the data security and privacy using XML encryption and compression.The prototype developed in a cloud environment was put into use in dozens of military hospitals to enable the sharing of clinical information.Conclusion This cloud computing platform has the advantages of dynamic scalability, distributed and ubiquitous access.It is highly feasible and practical for regional medical informatization.

The rapid development of medical informatization has ignited the explosive growth trend of medical service data, which is challenging data managers on the aspects of data amount, complex and multi-dimensional data relation and high interactive response demand. Traditional technology such as Data Warehouse (DW) and Business Intelligence (BI) could not meet the real-time demand of processing and analyzing the increasing scale of medical service big data. To solve this problem, in this paper we present a novel cloud platform for fast statistics and analysis based on big data processing technology. In this platform, medical service information is transformed to a new data structure in a column-oriented Data Base Manage System (DBMS), Spark cluster is used to satisfy the real-time computing requirements. Finally, we have developed a prototype to show results and details of statistics and analysis in the webpage.
