PSI is a global health organization dedicated to improving the health of people in the developing world by focusing on serious challenges like a lack of family planning, HIV and AIDS, barriers to maternal health, and the greatest threats to children under five, including malaria, diarrhea, pneumonia and malnutrition.

A hallmark of PSI is a commitment to the principle that health services and products are most effective when they are accompanied by robust communications and distribution efforts that help ensure wide acceptance and proper use.

In each of its platforms, PSI works in partnership with local governments, ministries of health and local organizations – creating health solutions that are built to last.

History
PSI was founded in 1970 to improve reproductive health using commercial marketing strategies. For its first 15 years, PSI worked mostly in family planning (hence the name Population Services International). In 1985, it started promoting oral rehydration therapy. PSI’s first HIV prevention project — which promoted abstinence, fidelity and condoms — began in 1988. PSI added malaria and safe water to its portfolio in the 1990s and tuberculosis in 2004.

Health Impact
PSI has an uncompromising focus on measurable health impact and measures its effect on disease and death much like a for-profit measures its profits. In 2011 alone, PSI helped prevent approximately 57.5 million malaria episodes and 481,000 malaria deaths; 4.7 million unintended pregnancies; 4.7 million cases of diarrhea; and 207,000 new HIV infections.
