Access to health care may vary across countries, communities and individuals, and is greatly influenced by social and economic conditions as well as existing health policies. Countries and jurisdictions have different policies and plans regarding personal and population healthcare goals in their communities. Health care systems are organizations established to meet the health needs of the population. According to the World Health Organization (WHO), a well-functioning health care system requires strong financing, a well-trained and adequately paid workforce, reliable information on which to base decisions and policies, and maintenance of health facilities to provide quality medicines and devices.

Healthcare can contribute to a large part of a country’s economy. In 2011, healthcare consumed an average of 9.3 percent of GDP or $3,322 per capita in the 34 OECD countries. Highest spenders: United States (17.7%, or $8.50), Netherlands (11.9%, 5,099), France (11.6%, 4,118), Germany (11.3%, 4,495), Canada (11.2%, 5,669), and Switzerland (11% , 5,634), but life expectancy in the total population was highest in Switzerland (82.8 years), Japan and Italy (82.7), Spain and Iceland (82.4), France (82.2) and Australia (82.0), while the OECD average exceeded 80. All OECD countries have achieved universal (or near universal) health coverage, with the exception of the United States and Mexico.
An example of a healthcare achievement is the global elimination of smallpox in 1980, declared by the World Health Organization as the first disease in human history to be completely eradicated through healthcare interventions.
