The presentation covers the use of Scalable Predictive Analysis in Critically Ill Patients using a Visual Open Data Analysis Platform (RapidMiner). With the accumulation of large amounts of health related data, predictive analytics could stimulate the transformation of reactive medicine towards Predictive, Preventive and Personalized (PPPM) Medicine, ultimately affecting both cost and quality of care. However, high-dimensionality and high- complexity of the data involved, prevents data-driven methods from easy translation into clinically relevant models. Additionally, the application of cutting edge predictive methods and data manipulation require substantial programming skills, limiting its direct exploitation by medical domain experts. This leaves a gap between potential and actual data usage. The presentation addresses the problem by focusing on an open, visual environment, suited to be applied by the medical community (RapidMiner). As a showcase, a framework was developed for the meaningful use of data from critical care patients by integrating the MIMIC-II / III database in a data mining environment (RapidMiner) supporting scalable predictive analytics using visual tools (RapidMiner’s Radoop extension). Guided by the CRoss-Industry Standard Process for Data Mining (CRISP-DM), the ETL process (Extract, Transform, Load) was initiated by retrieving data from the MIMIC-II tables of interest. Using visual tools for ETL on Hadoop and predictive modeling in RapidMiner, robust processes for automatic building, parameter optimization and evaluation of various predictive models, under different feature selection schemes can be developed. Because these processes can be easily adopted in other projects, this environment is attractive for scalable predictive analytics in health research.
