Methodology
Methodology references, index notes, and technical documentation for the Global Health Impact project.
Drug Index
To evaluate the impact of the major drugs for malaria, tuberculosis and HIV/AIDS, we consider 1) the need for the drugs, 2) the drugs' effectiveness, and 3) access to the drug.

Disease Index
The Disease Index sums the global impact of the drugs for each disease. It displays the relative proportion of DALYs averted by disease. It is also possible to see the breakdown of some information about need, access to, and efficacy of key drugs for each disease.

Country Index
The Country Index sums all drugs' impacts within the country. So, for instance, if two drugs are used in some country and the first averts 1 million DALYs and the second averts 2 million, the country score would be 3 million DALYs averted.

Company Index
The Company Index sums the impact of all of a company's drugs. So, for instance, if one company makes two drugs that avert 3 and 6 million DALYs respectively, the Company Score would be 9 million DALYs averted.

Ethically Adjusted Life Year Calculations
GLOBAL HEALTH IMPACT
Measuring Health
Our models use the Disability Adjusted Life Year (DALY) to calculate health needs and impact. Some worry, however, that the DALY discriminates against the disabled. This paper adapts a fixed-plus-variable framework proposed in welfare economics to the case of health measurement to proposes a novel measure called the Ethically Adjusted Life Year (EALY).
