- Background. Although physical therapy is a proven and recommended intervention for managing rheumatoid arthritis (RA), few studies have explored correlates of physical therapy service use among people with RA.
Objective. The purposes of this study were: (1) to describe physical therapy use among people with RA and (2) to identify biopsychosocial factors associated with physical therapy use. It was expected that use of physical therapy services would be lower than previously reported, considering recent medical advancements, and that including contextual factors may lead to identification of new factors associated with physical therapy use.
Design. This was a cohort study.
Methods. Of 1,032 patients prospectively recruited from a large hospital registry, 772 completed baseline and laboratory assessments, received a physical examination, and completed a 1-year follow-up survey regarding physical therapy service use. Measures included: demographics (ie, age, sex, marital status, race, employment, disability status, insurance, income, comorbidities, and education), disease duration, RA medications, self-efficacy (assessed with the Arthritis Self-Efficacy Scale), social support (assessed with the Berkman-Syme Social Network Index), function (assessed with the Multi-Dimensional Health Assessment Questionnaire), and disease activity (assessed with the Rheumatoid Arthritis Disease Activity Index). Self-reported use of physical therapy (yes/no) was assessed at the 1-year follow-up. A staged regression approach, based on a theoretical model, was used to select and enter variables into the regression to develop a parsimonious set of predictors.
Results. The patients were well educated and had modestly high incomes, and most had health insurance. Approximately 15.3% of the patients used physical therapy services during the designated follow-up period. Using multivariable modeling, the most significant predictors of physical therapy service use were moderate to high disease activity (odds ratio [OR]=1.4, 95% confidence interval [CI]=1.1-1.8), less than a college education (OR=0.5, 95% CI=0.2- 0.8), greater social networks (OR=2.1, 95% CI=1.3-3.5), and being on disability (OR=2.4, 95% CI=1.3- 4.6).
Limitations. The limitations of this study were use of a convenience sample and the potential for misclassification of physical therapy service use.
Conclusions. Patients with less than college education were less likely to receive physical therapy services, and those with more active disease, those who were on disability, and those who had greater social networks were more likely to receive physical therapy services.
