Is US Health Really the Best in the World?

Abstract

INFORMATION CONCERNING THE DEFICIENCIES OF US MEDIcal care has been accumulating. The fact that more than 40 million people have no health insurance is well known. The high cost of the health care system is considered to be a deficit, but seems to be tolerated under the assumption that better health results from more expensive care, despite evidence from a few studies indicating that as many as 20% to 30% of patients receive contraindicated care. In addition, with the release of the Institute of Medicine (IOM) report “To Err Is Human,” millions of Americans learned, for the first time, that an estimated 44000 to 98000 among them die each year as a result of medical errors. The fact is that the US population does not have anywhere near the best health in the world. Of 13 countries in a recent comparison, the United States ranks an average of 12th (second from the bottom) for 16 available health indicators. Countries in order of their average ranking on the health indicators (with the first being the best) are Japan, Sweden, Canada, France, Australia, Spain, Finland, the Netherlands, the United Kingdom, Denmark, Belgium, the United States, and Germany. Rankings of the United States on the separate indicators are: • 13th (last) for low-birth-weight percentages • 13th for neonatal mortality and infant mortality overall • 11th for postneonatal mortality • 13th for years of potential life lost (excluding external causes) • 11th for life expectancy at 1 year for females, 12th for males • 10th for life expectancy at 15 years for females, 12th for males • 10thforlifeexpectancyat40yearsforfemales,9thformales • 7th for life expectancy at 65 years for females, 7th for males • 3rd for life expectancy at 80 years for females, 3rd for males • 10th for age-adjusted mortality The poor performance of the United States was recently confirmed by the World Health Organization, which used different indicators. Using data on disability-adjusted life expectancy, child survival to age 5 years, experiences with the health care system, disparities across social groups in experiences with the health care system, and equality of family out-of-pocket expenditures for health care (regardless of need for services), this report ranked the United States as 15th among 25 industrialized countries. Thus, the figures regarding the poor position of the United States in health worldwide are robust and not dependent on the particular measures used. Common explanations for this poor performance fail to implicate the health system. The perception is that the American public “behaves badly” by smoking, drinking, and perpetrating violence. The data show otherwise, at least relatively. The proportion of females who smoke ranges from 14% in Japan to 41% in Denmark; in the United States, it is 24% (fifth best). For males, the range is from 26% in Sweden to 61% in Japan; it is 28% in the United States (third best). The data for alcoholic beverage consumption are similar: the United States ranks fifth best. Thus, although tobacco use and alcohol use in excess are clearly harmful to health, they do not account for the relatively poor position of the United States on these health indicators. The data on years of potential life lost exclude external causes associated with deaths due to motor vehicle collisions and violence, and it is still the worst among the 13 countries. Dietary differences have been demonstrated to be related to differences in mortality across countries, but the United States has relatively low consumption of animal fats (fifth lowest in men aged 55-64 years in 20 industrialized countries) and the third lowest mean cholesterol concentrations among men aged 50 to 70 years among 13 industrialized countries. The real explanation for relatively poor health in the United States is undoubtedly complex and multifactorial. From a health system viewpoint, it is possible that the historic failure to build a strong primary care infrastructure could play some role. A wealth of evidence documents the benefits of characteristics associated with primary care performance. Of the 7 countries in the top of the average health ranking, 5 have strong primary care infrastructures. Although better access to care, including universal health insurance, is widely considered to be the solution, there is evidence that the major benefit of access accrues only when it facilitates receipt of primary care. The health care system also may contribute to poor health through its adverse effects. For example, US estimates of the combined effect of errors and adverse effects that occur because of iatrogenic damage not associated with recognizable error include: • 12000 deaths/year from unnecessary surgery • 7000 deaths/year from medication errors in hospitals • 20000 deaths/year from other errors in hospitals
