population health - data & visualizations for decision making
DESCRIPTION
Measurement is key for population health management. Global Burden of Disease provides data on burden by disease, injury and risk factor in countries around the world.TRANSCRIPT

Institute for Health Metrics and Evaluation (IHME)
• Independent research center at the University of Washington
• Core funding by Bill & Melinda Gates Foundation and State of Washington
• 190 faculty, researchers and staff
• Providing rigorous, scientific measurement– What are the world’s major health problems?
– How well is society addressing these problems?
– How should we best dedicate resources to improving health?
Goal:
improve health
by providing the best
information
on population health

Managing population health
Goals
• Improve health outcomes
• Control cost
• Compare risk-adjusted outcomes / quality
• Identify and manage high-risk / high-cost patients
Identify affordable
inter-ventions
Target interventions at sub-populations/
individuals
Measure health
outcomes & risk factors

Measuring outcomes: Global Burden of Disease
• A systematic scientific effort
to quantify the comparative magnitude of
health loss due to diseases, injuries & risk factors
• Applied to different populations– Administrative: global, regional, country, sub-national
(e.g. LA county, Shilin county, Paris)
– Other populations (e.g. General Motors employees)
• GBD 2010 published in the Lancet in 2012(complete revision)

GBD 2013 to be published this fall
• 323 diseases and injuries, 1,500+ sequelae, 69 risk factors
• 188 countries, 1990 to 2013
• Results publicly available
• Collaborative model:1050 experts,106 countries

Communicating Data for Impact
• Target specific audiences
• Pick relevant format– Publication in major medical journals
– Policy reports
– Infographics
– Data visualizations
• Tailor granularity of data

Powerful data for population health management• Synthesis of all available data
• Innovative, peer reviewed methods
• Consistent methods make results comparable
• Uncertainty bounds for all metrics
• Coverage of all causes preventsdouble-counting,e.g. mortality, anemia
• Fully imputed dataset
14www.healthdata.org
Looking ahead
• Taking GBD sub-national– Successful collaborations with UK, China,
Mexico
– US burden at county level
• Expenditure by disease
• Forecasts
