TL/DR –
Health care spending in the US has slowed down due to the development of cheaper and more effective medical treatments. The downturn has been attributed to factors including price reductions in areas like medical imaging, a switch to generic drugs, and technological advancements that improve health and lower costs. However, despite these advances, the authors of a study into the trend argue that more changes are needed to reduce US medical spending further, in line with the 12% of GDP spent in other advanced economies.
Technological Advances Slow US Healthcare Spending Growth
The rate of healthcare spending growth in the United States appears to have significantly reduced, largely due to technological advancements making medical treatments more affordable and effective. This observation was mentioned in a paper set for discussion at the Brookings Papers on Economic Activity (BPEA) conference on March 27.
US healthcare expenditures exceeded $5 trillion, or 18% of the nation’s GDP, in 2024. While this represents a slight increase from 17.2% in 2010, it is substantially less than the expected 21.2% of GDP ($1 trillion less) predicted by government actuaries in 2010.
Unprecedented Slowdown in Medical Spending
The authors, David M. Cutler and Lev Klarnet from Harvard University, noted that the slowing growth of medical expenses is historically unprecedented. The period from 2010 to 2024 witnessed the slowest growth in medical spending compared to GDP since 1960.
The researchers attribute the slower growth to price declines in some areas, such as medical imaging, and the switch to generic drugs from their branded counterparts. In addition, the use of some expensive medical technologies, like advanced imaging and new drugs, has plateaued.
Impact of Technological Change on Healthcare Costs
They emphasize the role of technological change in managing healthcare costs. In the past, new technologies usually increased costs while having limited effectiveness. However, recent advancements have not only improved health outcomes but also reduced costs. Examples include the shift towards outpatient surgeries from inpatient ones and the widespread use of preventative drugs, like statins.
Cutler explained in an interview with the Brookings Institution that less invasive treatments also result in lower costs. He believes that the trend of slower healthcare spending growth will continue due to the changing nature of technological innovations.
The Future of US Healthcare Spending
Despite the positive trajectory, the authors warn that additional changes will be needed to align the US healthcare spending closer to the 12% of GDP seen in other developed economies. They argue that the higher medical spending in the US is not justified by health outcomes, and that even insured individuals find it increasingly difficult to access care. Cutler suggests that substantial savings could be achieved by reducing unnecessary care and leveraging AI, which could also improve the experience for doctors and patients.
