Abstract
Clinical features are known to influence pain in patients, but demographic characteristics have been less studied. The aim of this cross-sectional study was to evaluate the relationship of distance to exercise facilities and other demographic factors to the pain and function score, RAPID3 (Routine Assessment of Patient Index Data) in a large rheumatology practice.
The study data were extracted from an academic medical center electronic health record for established adult rheumatology outpatients. Multivariate linear regression quantified the relationship between the RAPID3 and age, sex, race, insurance status, rheumatologic condition (inflammatory or not), and geocoded distance from residential address to the closest indoor exercise facility. The mean RAPID3 differed significantly between subgroups for categorical variables (P<0.001) in the 4,937 patients studied. In the adjusted multivariate regression model, an increase in 5 kilometers between patient residence and the nearest exercise facility, was associated with a rise in the RAPID3 by 0.13 (P=0.04). RAPID3 also rose if the patient was a current smoker (β=3.4, P<0.001). There was a significant decrease in RAPID3 for men (β=-1.1, P<0.001), those of white race (β=-1.2, P=0.008), advancing age (β=-0.05 unit/year, P<0.001), those with inflammatory rheumatologic conditions (β=-2.3, P<0.001), and commercial insurance (β=-2.6, P<0.001).
Patients who are current smokers, female, non-white, younger, have non-commercial insurance, primarily noninflammatory rheumatologic conditions, and who reside further from exercise facilities, do worse as measured by the RAPID3. These factors should be considered when optimizing therapies for the rheumatology patient population.
