The Global Burden of Diseases, Injuries, and Risk Factors (GBD) is an approach to global descriptive epidemiology. It is a systematic, scientific effort to quantify the comparative magnitude of health loss due to diseases, injuries, and risk factors by age, sex, and geographies for specific points in time.
The GBD is led by the Institute for Health Metrics and Evaluation (IHME) at the University of Washington, Comparison is at the heart of the GBD approach. For decision-makers, health-sector leaders, researchers, and informed citizens, the GBD approach provides an opportunity to see the big picture, to compare diseases, injuries, and risk factors, and to understand in a given place, time, and age-sex group, what are the most important contributors to health loss.
To ensure a health system is adequately aligned to a population’s true health challenges, policymakers must be able to compare the effects of different diseases that kill people prematurely and cause ill health and disability.
Going forward, the GBD will produce ongoing estimates of all-cause mortality, deaths by cause, years of life lost (YLLs), years lived with disability (YLDs), and disability adjusted life years (DALYs) for a comprehensive cause list--including, at minimum, the 291 causes of diseases and injuries and the 67 risk factors estimated in the GBD Study 2010
The core costs of the ongoing estimation are supported in part through funding from the Bill & Melinda Gates Foundation; the critical milestones for that support include annual updates to the GBD estimates.
This protocol is specific to the next GBD update, the GBD 2013. When the new estimates for GBD 2013 are produced, the entire time series back to 1990 will be re-estimated using all available data to ensure the most complete and highly comparable set of estimates possible ; previous results will be archived every time new results are released.
