Objectives: Low back pain (LBP) is common among patients with an opioid use disorder (OUD). The extent to which patients with an OUD initiate physical therapy for LBP is unknown. The aim of this study was to examine the association between a history of an OUD and initiation of physical therapy for LBP within 60 days of a primary care provider (PCP) visit for this condition.
Methods: Claims from a single state-wide all payer claims database from June 30, 2013 and August 31, 2015 were used to establish a retrospective cohort of patients who consulted a PCP for a new episode of LBP. The outcome measure was patients who had at least 1 physical therapy claim within 60-days after the PCP visit. After propensity score matching on covariates, logistic regression was used to compare the outcome of patients with a history of an OUD to patients without an OUD.
Results: Propensity score matching resulted in 1360 matched pairs of participants. The mean age was 47.2 years (15.9) and 55.9% were female. Compared to patients without an OUD, patients with an OUD were less likely to initiate physical therapy for LBP (adjusted odds ratio = 0.65, 95% confidence intervals:0.49-0.85).
Conclusions: After a visit to a PCP for a new episode of care for LBP, patients with a history of an OUD are less likely to initiate physical therapy.
