## What is DALY averted?

DALYs averted counts the number of DALYs that are not lost, but averted, by a health intervention. By using DALYs averted, the organization could estimate the health impact of its products, services, and behavior change interventions across all of its health areas.

## How much does a Daly cost?

The average cost per DALY averted in countries with very high HDI was about 70 times higher than low HDI countries (\$69,499 vs \$998). In other words, on average, it costs about \$70,000 to avoid one DALY in very high HDI countries, while in low HDI countries, about 70 DALYs can be avoided with this cost.

How is DALYs averted calculated?

To calculate impact in DALYs averted, the reduction in mortality is multiplied by the number of years between average age at death for the targeted disease and ideal life expectancy.

What does icer stand for?

The Institute for Clinical and Economic Review (ICER) produces reports, known as “cost effectiveness analyses” or “value assessments” on how much it thinks new drugs should cost.

### Why do we use DALYs?

DALYs are most useful for measuring the burden of disease for the population. The whole population of young people aged 10-24 has millions of healthy life years ahead of them, and death or even severe incapacitation are rare.

### What is a DALY and how is it calculated?

Mathematically, a DALY is represented by the equation DALY = YLL + YLD. YLL is calculated as the number of deaths (n) x the standard life expectancy at age of death (L1). This measures the reduction in life expectancy.

Why is DALY important?

DALYs measure the health gap from a life lived in perfect health, and quantify this health gap as the number of potentially healthy life years lost due to morbidity, disability and mortality. A disease burden of 100 DALYs per 1000 people-year would thus imply a loss of 100 healthy life years per 1000 people per year.

What are the benefits of using DALY?

The main advantage is that DALYs provide a composite, internally consistent measure of population health which can be used to evaluate the relative burden of different diseases and injuries and compare population health by geographic region and over time.

#### What are QALYs and DALYs?

QALYs are years of healthy life lived; DALYs are years of healthy life lost. Both approaches multiply the number of years (x axis) by the quality of those years (y axis). QALYs use “utility weights” of health states; DALYs use “disability weights” to reflect the burden of the same states.

#### What is ICER threshold?

Services less than one times per capita GDP (High value: ICER < US\$50,000/QALY; Intermediate value: ICER US\$50,000–150,000/QALY; Low value: ICER >US\$150,000/QALY.

How do you explain DALYs?

One DALY represents the loss of the equivalent of one year of full health. DALYs for a disease or health condition are the sum of the years of life lost to due to premature mortality (YLLs) and the years lived with a disability (YLDs) due to prevalent cases of the disease or health condition in a population.
