Shifting the Data Paradigm
• Reactive reporting
• 3 – 6 month delay
• Regulatory-centric
• Manual data review/collection
• Repressive data silo’s
• Not sure what data to store
• Expensive storage w/limited options
 All data types (structured, semi
structured, & Unstructured)
 Near real-time and predictive
 Organization & Patient centric
 Store everything
 Inexpensive storage w/lots options

Monitor Patient Vitals in Real-Time with Sensor data
Problem
Managing The Volumes of System Sensor Data
• In a typical hospital setting, nurses do rounds and manually monitor patient vital signs.
They may visit each bed every few hours to measure and record vital signs but the
patient’s condition may decline between the time of scheduled visits.
• This means that caregivers often respond to problems reactively, in situations where
arriving earlier may have made a huge difference in the patient’s wellbeing.
Solution
Hadoop Empowers Healthcare by Converting High Volumes of Sensor Data into a
Manageable Set of Data
• New wireless sensors can capture and transmit patient vitals at much higher
frequencies, and these measurements can stream into a Hadoop cluster.
• Caregivers can use these signals for real-time alerts to respond more promptly to
unexpected changes.
• Over time, this data can go into algorithms that proactively predict the likelihood of an
emergency even before that could be detected with a bedside visit.
Benefits
Proactively Predict Events
rather than reactively
Real-time Alerts
Capture & Transmit Patient
Vitals at Much Higher
Frequencies
Improve Patient Satisfaction
Improve operational efficiency
Improved response times
Reduce adverse drug
response times

What is Data Virtualization?
Data Virtualization combines disparate data sources into a single “virtual” data
layer (aka information fabric abstraction) that provides unified access and
integrated data services to consuming applications in real-time (right-time).
