The value of medical spending in the United States, 1960-2000.

BACKGROUND The increased use of medical therapies has led to increased medical costs. To provide insight into the value of this increased spending, we compared gains in life expectancy with the increased costs of care from 1960 through 2000. METHODS We estimated life expectancy in 1960, 1970, 1980, 1990, and 2000 for four age groups. To control for the influence of nonmedical factors on survival, we assumed in our base-case analysis that 50 percent of the gains were due to medical care. We compared the adjusted increases in life expectancy with the lifetime cost of medical care in the same years. RESULTS From 1960 through 2000, the life expectancy for newborns increased by 6.97 years, lifetime medical spending adjusted for inflation increased by approximately 69,000 dollars, and the cost per year of life gained was 19,900 dollars. The cost increased from 7,400 dollars per year of life gained in the 1970s to 36,300 dollars in the 1990s. The average cost per year of life gained in 1960-2000 was approximately 31,600 dollars at 15 years of age, 53,700 dollars at 45 years of age, and 84,700 dollars at 65 years of age. At 65 years of age, costs rose more rapidly than did life expectancy: the cost per year of life gained was 121,000 dollars between 1980 and 1990 and 145,000 dollars between 1990 and 2000. CONCLUSIONS On average, the increases in medical spending since 1960 have provided reasonable value. However, the spending increases in medical care for the elderly since 1980 are associated with a high cost per year of life gained. The national focus on the rise in medical spending should be balanced by attention to the health benefits of this increased spending.
