The multidimensional nature of chronic pain is not reflected by definitions based solely on pain duration, resulting in high prevalence estimates limiting effective policy development. The newly proposed concept of high-impact chronic pain (HICP) incorporates both disability and pain duration to identify a more severely impacted portion of the chronic pain population yet remains uncharacterized at the population level. As such, we used the 2011 National Health Interview Survey (N = 15,670) to 1) assess the likelihood of disability in the overall chronic pain population, 2) estimate the prevalence of HICP, and 3) characterize the disability, health status, and health care use profile of this population in the United States. ⋯ Understanding this heterogeneity will contribute to developing more effective legislation promoting safe and cost-effective approaches to the prevention and treatment of chronic pain. PERSPECTIVE: HICP is a powerful new classification that differentiates those with debilitating chronic pain from those with less impactful chronic pain. By addressing the multidimensionality of chronic pain, this classification will improve clinical practice, research, and the development of effective health policy.
