·You must know the diagnosis to deliver effective and high quality care to patients; likewise for health systems to be effective, it is necessary to understand what the global burden of disease is.
·In 1991, the World Bank and World Health Organization launched the Global Burden of Disease Study which as of 2010 evaluates 291 disease and injuries as well as 1160 sequelae of these causes.
·In order to compare the burden of one disease with that of another, you must consider death and life expectancy of persons affected by the disease as well as disability imposed by the condition.
·The combined composite summary metric is termed disability adjusted life years (DALYs).
·There have been three major worldwide studies to date (1990, 2005, 2010) attempting to quantify the burden of disease yet no study to date has ever attempted to quantify the burden of disease requiring emergent intervention.
Bottom Line:
DALYs are a useful tool for quantifying the burden of disease and provides essential input into health policy dialogues to identifies conditions and risk factors that may be relatively neglected and others for which progress is not what was expected. To date, there has been no rigorous scientific effort to quantify the burden of disease worldwide that requires emergent intervention to avoid death and disability.
