Patients who consult a physical therapist for low back pain (LBP) may receive initial and subsequent management from different therapists. The impact that physical therapy provider continuity has on health care utilization in patients with LBP is under studied.
The objective of this study was to examine the impact of physical therapy provider continuity on health care utilization and costs in patients with LBP referred from primary care.
The study design included a retrospective analysis of claims data.
Data from an all-payer claims database was examined. Logistic regression was used to evaluate the association between physical therapy provider continuity and health care utilization during the 1-year period following a visit with a primary care provider for LBP.
Patients who experienced greater physical therapy provider continuity had a decreased likelihood of receiving lumbar surgery. They also paid less (mean = $1737 [95% confidence interval, $1602–$1871]) than those who experienced less physical therapy provider continuity (mean = $2577 [95% confidence interval, $2008–$3145]).
The degree of causality between any predictor and outcome variables cannot be determined due to the observational nature of the study.
High physical therapy provider continuity appears to be associated with a decreased likelihood of lumbar surgery and lower LBP-related health care costs.
