Two decades of data reveal overall increase in pain, opioid use among U.S. adults

Feb. 14, 2019

A recent study provides new insights concerning pain trends and opioid use for pain management. Data from the Medical Expenditure Panel Survey (MEPS) was used to examine the impact of pain-related interference, a measure of pain’s impact on normal work activities, on people’s health status and healthcare use. MEPS is a nationally representative survey of the U.S. civilian, noninstitutionalized population.

Researchers showed that the number of U.S. adults age 18 and older suffering from at least one painful health condition increased substantially from 120.2 million (32.9 percent) in 1997/1998 to 178 million (41 percent) in 2013/2014. Furthermore, the use of strong opioids, like fentanyl, morphine, and oxycodone, for pain management among adults with severe pain-related interference more than doubled from 4.1 million (11.5 percent) in 2001/2002 to 10.5 million (24.3 percent) in 2013/2014.

These are the findings of a comprehensive analysis of 18-year trends showing changes in the overall rates of noncancer pain prevalence and management. The full study, conducted by the National Center for Complementary and Integrative Health (NCCIH), part of the National Institutes of Health; Social & Scientific Systems, Inc., Silver Spring, MD; and Yale University School of Medicine, New Haven, CT; was published in the Journal of Pain.

The number of U.S. adults suffering from at least one painful condition has increased. The study showed that by 2013/2014, about one-third of individuals (68 million) with a painful health condition reported moderate or severe pain-related interference with normal work activities. The analysis of MEPS data looked specifically at noncancer painful health conditions. The researchers also found that people with severe pain-related interference were more likely to use strong opioids, to have had four or more opioid prescriptions, and to have visited a doctor’s office six or more times for their pain compared to those with minimal pain-related interference.

As with other studies, this analysis showed an increase in the overall use of opioids between 1997 and 2014, with a peak use observed between 2005 and 2012.

The study also shows small changes in the prevalence of ambulatory office visits, emergency room visits, or hospitalization for pain. Ambulatory office visits for pain plateaued between 2001/2002 and 2007/2008, then decreased through 2013/2014. In addition, the researchers found a decrease in the number of pain-related emergency room visits and overnight hospital stays among those reporting at least one painful condition.
