What Explains Poor Health-related Quality of Life Associated With Opioid Use Among Adults With Chronic Noncancer Pain Conditions? A Blinder-Oaxaca Decomposition

The objective of this study was to estimate the extent to which differences in person-level characteristics between opioid users and nonusers contribute to poor health-related quality of life (HRQoL) of long-term opioid users with chronic noncancer pain condition (CNCP). Materials and Methods: We conducted a retrospective cohort study of adults (n=5917) using longitudinal data from multiple years of Medical Expenditure Panel Survey. Adults with CNCP were classified into short-term, long-term, and opioid nonusers. We measured HRQoL with physical component summary (PCS) and mental component summary (MCS) scores from the Short-Form 12 Questionnaire. A regression decomposition analysis of results from linear regression was performed. Results: Among adults with CNCP, 17.8% and 17.2% reported long-term and short-term opioid use, respectively. Long-term opioid users had lower PCS scores (β=−4.48; P
