Big Data = Complete Data The Electronic Medical Record is primarily transactional taking feeds from source systems via an interface engine. The Enterprise Data Warehouse is a collection of data from the EMR and various source systems in the enterprise. In both cases decisions are made concerning data acquisition. Hadoop is capable of ingesting and storing healthcare data in total.
Big Data = Infrastructure Low Cost of Entry & Scalable – Open Source – Commodity Hardware UCI Hadoop Ecosystem – 8 nodes – 4 terabytes Yahoo Hadoop Ecosystem – 60K nodes – 160 petabytes Cloud Ready
Big Data = Interoperability An Ecosystem that Supports – Hadoop (HDFS) – MongoDB (NoSQL) – Neo 4j (Graph Database) – Relational Data Base – MapReduce – JBoss Drools – Mahout
Limits of Current Ecosystem The Electronic Medical Record is not up to the task of handling complex operations such as anomaly detection, machine learning, building complex algorithms or pattern set recognition. Enterprise Data Warehouses (EDW) suffer from a latency factor of up to 24 hours. The EDW serves clinicians, operations, quality and research retrospectively as opposed to real time.
Saritor Data Information Knowledge Wisdom A healthcare information ecosystem built on “Big Data” technologies capable of serving the needs of clinicians, operations, quality and research in real time and in one environment. Able to ingest all healthcare generated data both internal and external. Platform for advanced analytics such as early detection of sepsis & hospital acquired conditions. Prediction of potential readmissions. Complex algorithm and machine learning platform.
