Abstract

Claims-based analysis of cohorts of TRICARE Prime beneficiaries.To compare rates of utilization of 5 LBP treatments (physical therapy, manual therapy, behavioral therapies, opioid and benzodiazepine prescription) across catchment areas and assess their association with resolution of LBP.Guidelines support focusing on nonpharmacologic management for LBP and reducing opioid use. Little is known about patterns of care for LBP across the Military Health System.Incident LBP diagnoses were identified data using International Classification of Diseases Ninth Revision before October 2015 and Tenth Revision after October 2015; beneficiaries with "red flag" diagnoses and those stationed overseas, eligible for Medicare, or having other health insurance were excluded. After exclusions, there were 159,027 patients remained in the final analytic cohort across 73 catchment areas. Treatment was defined by catchment level rates of treatment to avoid confounding by indication at the individual level; the primary outcome was resolution of LBP defined as absence of administrative claims for LBP during the 6-12 month period following the index diagnosis.Adjusted rates of opioid prescribing across catchment areas ranged from 15% to 28%, physical therapy from 17% to 39%, and manual therapy from 5% to 26%. Multivariate logistic regression models showed a negative and marginally significant association between opioid prescriptions and LBP resolution (odds ratio 0.97, 95% C.I. 0.93 to 1.00; P=0.051) but no significant association with physical therapy, manual therapy, benzodiazepine prescription, or behavioral therapies. When the analysis was restricted to the subset of only active-duty beneficiaries, there was a stronger negative association between opioid prescription and LBP resolution (odds ratio 0.93, 95% C.I. 0.89 to 0.97).We found substantial variability across catchment areas within TRICARE for the treatment of LBP. Higher rates of opioid prescription were associated with worse outcomes.
