Large-scale clinical data management and analysis system based on cloud computing

Abstract

With the exponential increase of Electronic Health Record systems in China, large-scale clinical data management and analysis have become big challenges. This paper depicts a novel system named Clinical Data Managing and Analyzing System, which uses hybrid XML database, and HBase/Hadoop infrastructure to handle big amount of heart disease clinical data analysis online. Using standardized format of Clinical Document Architecture, the system now has integrated more than 50,000 valvular heart disease clinical documents and provided efficient distributed data mining tools as well as data managing tools for doctor users from multi heart clinical centers in six different 3A hospitals of China. © Springer Science+Business Media Dordrecht 2014.
