This document provides an overview of sources of big data in healthcare and their applications. It discusses traditional sources like medical claims, electronic health records, and medical imaging. It also examines emerging sources like internet of things sensor data, social media data, mobile network data, and satellite imagery. The document outlines how these diverse data sources can be used for applications like personalized healthcare, disease surveillance, disaster management, and climate change adaptation. It concludes that big data opens new opportunities to improve healthcare through right interventions for patients. However, issues around data representativeness and bias must be addressed.

The doctor of the future will give no medicine, but instead will interest his
patients in the care of human frame, in diet, and in the cause and prevention of
disease.
Thomas Edison (1847 – 1931)
Big data healthcare market is estimated to grow from $10bn in
2016 to reach $27.6bn by 2021 at a robust CAGR of 22.3%.

The IoT has already made
waves in the energy and
utilities, home monitoring, and
transportation industries, and
the number of connected
things in healthcare is
growing.
Data streams do not provide
confirmed infection status for
specific pathogens.
Provide individual-level
health data in near real time
Derive from use of Internet
search engines, social media,
or mobile phones.
Self-reporting of health
outcomes.
Provide information on health-
related behavior, including
contact and travel patterns,
vaccine status and sentiments.
Key ingredients for
understanding and modeling
disease transmission.
Hospital discharge records
Death certificates
Provide information on
disease status.
Can be monitored at the
individual level or
aggregated geographically
before reporting.

• Imagery
• Cell Phone Triangulation LT5534 power signal detectors
• Re-establish Communication Networks
• Iridium 9602 M2M
• CPS Interactions
• Site Embedded
• Mobile
• Semi-Autonomous Operations - Swarm
17. Climate Change Adaptation
Interaction between Climate, Water and Society (people and
infrastructure). Red arrows indicate key fluxes where models need to
be integrated and model interfaces developed.
Major interactions between model blocks (b) Interfaces providing
aggregation or discretization for temporal scales (c) Interfaces
providing conversion between dimensions and spatial scale
22. Conclusion
✓ Big Data has opened up new possibilities to analyze traditional data sources
in conjunction with other heterogenous data sources
✓ These new data resources are getting enriched every milliseconds and
available all around the world
✓ Those in the field of disease surveillance and modeling can learn a lot from
other data-and modeling fields, such as meteorology and marketing, and can
ultimately provide useful tools to improve situational awareness and outbreak
response for a variety of old and new diseases.
✓ An effort to design policy, regulation and Big Data governance schemes may
facilitate “Personalized care through right intervention to the right patient
at the right time”
