Healthcare data
• Transformative changes:– Accrual of large historic datasets– Interoperability of systems– Data warehouses
• Opportunities– Provide epidemiological data– Assess value in health spending– Provide new insights for increasing value
Challenges
• Traditional analytic techniques not scalable to big data
• Trans border data flows into the United States and the USA PATRIOT Act
• Need bricks and mortar big data solutions• Lack of infrastructure• Lack of expertise
What is big data in pathology?
• Genome sequences: bioinformatics– Shah NH. Translational bioinformatics embraces big data.

Example – Calgary Laboratory data
• Since 2010: 125,000,000 lab tests• Each with 100+ pieces of metadata
– 1.25 x 1010 data elements• Linkage to demographic, pharmacy,outcomes
data– 1.25 x 1012 data elements
