Dose and Duration of Opioid Use in Propensity Score-Matched, Privately Insured Opioid Users With and Without Spinal Cord Injury.

The study used prescription claims, so it shows opioid prescriptions, not whether patients actually took the medication, diverted it, or obtained opioids from other sources. It included only privately insured adults aged 18 to 64 years, so patterns may differ for uninsured people, people with Medicaid or Medicare, or other age groups. The claims data did not include pain severity, quality of life, neurologic completeness, time since injury, surgery, ethnicity, or socioeconomic status, so important clinical differences may not have been captured. The data did not include level-specific diagnostic codes for 50.89% of persons in the spinal cord injury cohort, which limited the subgroup analysis to 174 participants. Propensity score matching balanced only observed variables, so it cannot rule out unmeasured differences between the spinal cord injury and control groups. No participant met the high-dose short-acting opioid criterion, so the study could not compare high-dose short-acting use between groups.

The supplied article text does not include a conflicts-of-interest or funding declaration. The publication types list NIH extramural and non-U.S. government research support.

Do not read these differences as proof that spinal cord injury causes higher opioid use or that opioids are effective. The study compared prescription patterns, not actual medication use or pain outcomes, and it cannot rule out unmeasured differences between the groups.
