FRIDAY, Sept. 14 (HealthDay News) -- Americans spend as much as $635 billion each year on the direct and indirect costs associated with chronic pain, according to a new study.
That's more than the annual costs associated with cancer, heart disease and diabetes, said study authors Darrell Gaskin and Patrick Richard, health economists at Johns Hopkins University. They based their estimate on health care costs and lost worker productivity associated with chronic pain.
The researches analyzed the 2008 Medical Expenditure Panel Survey to measure the incremental health care costs for people affected by chronic pain -- including pain that interferes with work, joint pain, arthritis and disabilities -- and compared them to costs for people without chronic pain. The study involved more than 20,200 U.S. adults.
The costs of certain conditions were calculated for a variety of payers of health care services, the researchers noted.
The study, published in the Journal of Pain, found average health care costs for adults were $4,475. People suffering from moderate pain paid $4,516 more in health care costs than those without pain, the researchers said. Patients with severe pain spent $3,210 more than people with only moderate pain. Costs were also $4,048 higher for those with joint pain, $5,838 higher for people with arthritis and $9,680 more for those with functional disabilities.
When prevalence of pain conditions was assessed, moderate pain accounted for 10 percent, severe pain accounted for 11 percent and disability represented 12 percent. Estimates for joint pain and arthritis were higher. They accounted for 33 percent and 25 percent of prevalence estimates, respectively.
The researchers noted that adults affected by chronic pain missed more workdays than people without pain. This affected their annual hours worked and hourly wages. The study concluded the total cost associated with pain in the United States was at least $560 billion and possibly as high as $635 billion, according to a release from the American Pain Society.
Broken down, the total incremental costs of health care resulting from chronic pain ranged from $261 billion to $300 billion. And the costs associated with lost productivity ranged from $299 billion to $334 billion. Although the per-person cost of pain is less than the cost of other diseases, the researchers said the total cost of chronic pain is higher. They said the costs associated with chronic pain would be even greater if they took into account nursing home residents, military personnel, prisoners, children and caregivers.
