Just 20 conditions make up more than half of all spending on health care in the United States, according to a new comprehensive financial analysis that examines spending by diseases and injuries.
The most expensive condition, diabetes, totaled $101 billion in diagnoses and treatments, growing 36 times faster than the cost of ischemic heart disease, the number-one cause of death, over the past 18 years. While these two conditions typically affect individuals 65 and older, low back and neck pain, the third-most expensive condition, primarily strikes adults of working age.
These three top spending categories, along with hypertension and injuries from falls, comprise 18% of all personal health spending, and totaled $437 billion in 2013.
This study, published today in JAMA, distinguishes spending on public health programs from personal health spending, including both individual out-of-pocket costs and spending by private and government insurance programs. It covers 155 conditions.
"While it is well known that the US spends more than any other nation on health care, very little is known about what diseases drive that spending." said Dr. Joseph Dieleman, lead author of the paper and Assistant Professor at the Institute for Health Metrics and Evaluation (IHME) at the University of Washington. "IHME is trying to fill the information gap so that decision-makers in the public and private sectors can understand the spending landscape, and plan and allocate health resources more effectively."
In addition to the $2.1 trillion spent on the 155 conditions examined in the study, Dr. Dieleman estimates that approximately $300 billion in costs, such as those of over-the-counter medications and privately funded home health care, remain unaccounted for, indicating total personal health care costs in the US reached $2.4 trillion in 2013.
Other expensive conditions among the top 20 include musculoskeletal disorders, such as tendinitis, carpal tunnel syndrome, and rheumatoid arthritis; well-care associated with dental visits; and pregnancy and postpartum care.
