In the 2008 "Journal of the American Medical Association" article "The Perfect Storm of Overutilization" Emanuel said, "Overall, US health care expenditures are 2.4 times the average of those of all developed countries ($2759 per person), yet health outcomes for US patients, whether measured by life expectancy, disease-specific mortality rates, or other variables, are unimpressive." He said that expensive drugs and treatments that provide only marginal benefits are the largest problems. Fee-for-service payments, physician directed pharmaceutical marketing, and medical malpractice laws and the resultant defensive medicine encourage overutilization. Direct-to-consumer marketing by pharmaceutical companies also drives up costs.
