There is substantial access to care barriers for persons with chronic pain. Little is known about persons who do not receive treatment for chronic severe back pain as most studies rely on clinical samples. We sought to explore demographic, socioeconomic, and clinical characteristics of U.S. adults with chronic severe back pain who had not received pain care in the preceding 3 months. In this cross-sectional study, we used data from the 2019 National Health Interview Survey and identified persons who did/did not receive treatment (including self-management strategies) in the last 3 months for their chronic severe back pain. We used bivariate and multivariable analyses to explore factors associated with not receiving pain treatment. Almost 21% of persons with chronic severe back pain did not receive treatment in the past 3 months. The following were independently associated with not having treatment in the preceding 3 months: male sex (OR: 1.40, 95% CI: 1.11–1.76), living near or below the poverty level (OR: 1.92, 95% CI: 1.33–2.77), having less than a high school education (OR: 2.37, 95% CI: 1.52–3.68), not having insurance coverage (OR: 1.77, 95% CI: 1.21–2.59), living in the South (OR: 2.05, 95% CI: 1.40–3.00), and having heart disease (OR: 1.47, 95% CI: 1.11–1.93). Being a single parent, having depression, and multiple comorbid painful health conditions were associated with having treatment. Our conclusions are that one-fifth of persons with chronic severe back pain did not receive treatment for at least 3 months and socioeconomic factors were highly associated with not receiving treatment.

In a nationally representative sample of persons with chronic severe back pain, one-fifth did not receive treatment for at least 3 months. Socioeconomic factors were highly associated with not receiving treatment. There is a need to implement solutions to reduce barriers to care.
