A study released this week in the Journal of the American Medical Association reports that total spending on medical research in the United States doubled to nearly $95 billion over the last decade, though whether the money is well spent requires further scrutiny, the study authors said. They called on the medical industry, government and foundations to do better at investing in research on diseases with fewer effective treatments, such as Alzheimer's, and at translating basic research into new treatments and cures. In their funding analysis, the authors found that the U.S. spends 6 cents of every health care dollar on medical research, but only one-tenth of a cent of every dollar on long-term evaluation of which drugs and treatments work best at the lowest cost.
