Pitcher MH, et al. - Researchers evaluated the likelihood of disability in the overall chronic pain population, estimated the prevalence of High Impact Chronic Pain (HICP, which represents a newly proposed concept which incorporates both disability and pain duration to identify a more severely impacted portion of the chronic pain population), and characterized the disability, health status and health care use profile of this population in the United States by using the 2011 National Health Interview Survey (NHIS; n=15,670). Subjects with chronic pain vs those with stroke or kidney failure had greater risk of disability, among others. HICP influenced 4.8% of the U.S. adult population, or approximately 10.6 million individuals in 2011. Compared with persons with chronic pain without disability, the HICP population experienced more severe pain, mental health and cognitive impairments, and was also more likely to report worsening health, more difficulty with self-care and higher health care use. Overall, these data support the utility of High Impact Chronic Pain for differentiating those with debilitating chronic pain from those with less impactful chronic pain.
