Health indicators are normally numbers and statistics. They are very useful to monitor the health care system and help decision makers to make decisions about health policies based on good evidence. Health indicators also provide a basis for comparison and can be used to show a population’s health changes over time or be used to compare populations to see which ones are healthier (HHS, 2012).
However, cautions should be taken while using health indicators to compare countries. For example, in terms of health expenditure, U.S. spent twice as much on health care than any other industrialized nations per capita, however, the other health indicators such as life expectancy and infant mortality showed modest health care performance for U.S. (Harrington & Estes, 2008, p. 385). Why? Because using some of the most popular health indicators, such as life expectancy and infant mortality, to evaluate the effectiveness of a health care system is debatable and those measurements are sometimes claimed to be flawed or unreliable.
According to Wenger’s study (2009), there is no relationship between life expectancy of a population and the number of physicians or hospitals available to them. Many people die in auto accidents, homicide, disasters, or other sudden death, which have limited interaction with health care system (Wenger, 2009). There is also no relationship between life expectancy and health care expenditures in the industrialized countries. In U.S., only 10 percent of premature deaths in the U.S. are related to the health care system. The
