The influence of rural versus urban residence on utilization and receipt of care for chronic low back pain

Abstract

Purpose: (1) To describe demographic and health-related characteristics among rural/urban residents with chronic low back pain (LBP); (2) To determine if the utilization of diagnostics and treatments differs between rural and urban residents with chronic LBP; and (3) To determine the association between rural/urban residence and health care provider usage and if associations differ by race or gender.

Methods: A 2006 cross-sectional telephone survey of a representative sample of North Carolina residents. Subjects with chronic LBP were questioned regarding their health and health care use. Wald and chi-square tests were used to determine differences between demographic and health-related characteristics of rural/urban residents. Logistic regression was used to determine the association between rural/urban residence and health care provider use. Differences in race or gender were explored with stratified analysis with a P < .10.

Findings: 588 residents of North Carolina with self-reported chronic LBP sought care from a provider in the previous year. In bivariate analyses, when compared to urban residents, rural residents were younger, more likely to be uninsured, reported significantly higher levels of disability, and reported more depression/sadness. Rural residents were less likely to receive care from a rheumatologist (adjusted odds ratio [aOR] 0.47 [95% CI, 0.22-0.99]). Rural blacks were less likely to receive care from a physical therapist when compared to urban blacks (aOR 0.26 [95% CI, 0.07-0.87]).

Conclusion: Despite similarities of high provider use, imaging and therapeutics, when compared to urban residents, rural residents reported higher levels of functional limitation and depression.
