Mental and physical health correlates of pain treatment utilization among veterans with chronic pain: a cross-sectional study

The annual cost of treatment and lost productivity due to chronic pain is estimated to be $635 billion within the USA. Self-management treatments for chronic pain result in lower health care costs and lower utilization of provider-management treatments, such as hospitalization and medication use. The current study sought to identify and characterize patient factors and health conditions associated with chronic pain treatment utilization to inform ways to improve engagement in self-management pain treatment (e.g., applying heat or ice, exercising, or practicing relaxation). This study predicted (1) greater pain intensity and pain interference would be associated with greater utilization of self-management treatments and (2) this association would be moderated by patient factors (gender and age) and health comorbidities (anxiety, trauma, depression, and sleep disturbance).Baseline data from a three-arm clinical trial were collected for 127 Veterans seeking treatment for chronic pain. Veterans were recruited via clinician referral and medical record review at the Veterans Affairs Puget Sound Health Care System, Washington, USA.Self-management treatments were more utilized than provider-management treatments. Pain intensity and pain interference were not uniquely associated with provider-management or self-management treatment utilization after controlling for demographics and mental health status. Sleep disturbance moderated the relationship between pain interference and provider-management treatment utilization. Depression moderated the relationship between pain intensity and provider-management treatment utilization.While study conclusions may not generalize to all Veteran populations, findings suggest that Veterans with chronic pain were more likely to seek provider-management treatments when experiencing high-pain interference and high-sleep disturbance. In addition, Veterans were more likely to seek provider-management treatments when experiencing low-pain intensity and high-depression symptoms
