Tracking Our Impact

TRACKING OUR IMPACT

We have an uncompromising focus on measurable health impact and we measure our effect on disease and death much like a for-profit measures its profits.

Our fundamental measure of health impact is the disability-adjusted life year (DALY) averted. When we avert one DALY, it means that we have prevented the loss of one year of productive, healthy life.

 

SO WHAT’S A DALY?

Essentially, it’s a year of healthy life lost.  People can lose a healthy year of life because of death or being sick (disability). When we avert one DALY, it means that we prevented the loss of one year of productive, healthy life – a year of life that, without our intervention, would have been lost to illness or death.

Measuring the Health of a Population

DALYs

It’s important to understand that a DALY is used to measure the health of a population, country, region etc. not just one person. So, to calculate the DALYs of a population, you would add up:

Still sound too complicated?
No worries, let’s break it down further with an example. The real calculations are a bit more complicated with models, coefficients, estimations, etc, but the CONCEPT is important to understand. And that’s what we’re focusing on here.
