Health care spending represents a growing proportion of gross domestic product (GDP) in Organization for Economic Co-operation and Development countries, as its share of GDP has increased on average by almost 2 percent per year over the past 40 years. years. Health care spending in the United States increased by an average of 6.2% per year between 1991 and 2011. Health care spending represented 17.9% of GDP in the United States in 2011. Many elements affect the increase in health costs. The proportion of older adults in the U.S. population is increasing, and an aging population can increase health care costs. Because, compared to younger people, older people use health services more because they are more likely to suffer from non-communicable diseases. Noncommunicable diseases are not caused by infection and cannot spread between people, such as heart disease, asthma, diabetes and cancer. Health care costs for non-communicable diseases are high and these diseases persist for a long time, which shows that health spending will increase due to the aging of the population. Another element of improving health is the increase in prices of medical treatments, consultations and medicines. healthcare costs. Rising prices of health services and medicines were the main reason for the increase in health care spending between 2009 and 2010. Low productivity is another element of the increase in health care costs. Given that there is little or no growth in productivity gains in the health care sector, health care costs would increase over time; and due to the inertia of demand, health expenditure would also increase (Baumol, 1988). Since it is difficult to measure the value of health care services, it is very difficult to assess productivity gains in health care.

Health promotion gives people information about healthy lifestyles and diseases at low cost, but it produces substantial results. This information helps people change their behaviors, seek help and diagnosis, and lead healthy lives. Health education and communication based on psychological and behavioral research must be supported to promote health and well-being. Self-care can prevent unnecessary visits to the doctor or hospital, which cost billions of dollars a year. Self-care teaches people how to become an informed consumer of health services. People learn when to see a doctor or hospital for health problems that merit it and when to use self-care for those that can be treated at home. People should be educated to make better decisions for their health.
