Abstract
Background and PurposeBecause musculoskeletal conditions contribute to functional decline and activity limitation, physical therapy intervention may be an appropriate health care resource. The purpose of this research was to identify determinants of outpatient physical therapy use by people with musculoskeletal conditions.SubjectsThe subjects were adult noninstitutionalized civilians who participated in the Medical Expenditure Panel Survey from 1996 to 2000 and who had at least one musculoskeletal condition (N=18,546).MethodsLogistic regression was used to identify predisposing, need, and enabling variables associated with receiving outpatient physical therapy services.ResultsFactors that were positively associated with receiving physical therapy services were having more than one musculoskeletal condition, having some limitation in function, having 7 or more ICD-9 (International Classification of Diseases, 9th Revision) codes, having a college or advanced degree, and residing in an urban area. Factors that were negatively associated with receiving physical therapy services were being older than 65 years of age, having no high school degree, Hispanic ethnicity, African-American race, having public insurance or no insurance, and living in any US census region besides the Northeast.Discussion and ConclusionThe results of this study indicate that health- and non–health-related factors influence outpatient physical therapy use.
