Utilization and Clinical Outcomes of Outpatient Physical Therapy for Medicare Beneficiaries With Musculoskeletal Conditions.

Background. Medicare beneficiaries frequently receive physical therapy for musculoskeletal conditions. Little information is available about this care.Objective. The purposes of this study were: (1) to describe characteristics, clinical outcomes, and utilization for Medicare beneficiaries receiving physical therapy in outpatient clinics within one integrated health care system; (2) to compare characteristics, outcomes, and utilization based on the body region affected; and (3) to examine factors predictive of outcomes and utilization.Design. This was a prospective, longitudinal study. Methods. Medicare beneficiaries aged 65 years or older (n1,840 episodes of care) participated in the study. Descriptive statistics were calculated for patient characteristics and outcomes. Comparisons were made based on body region. Regression models evaluated factors associated with change in pain, improved outcome,and utilization. Results. The patients' mean age was 74.2 years (SD6.3), and 65.3% were female. The most common body regions were the lumbar spine, shoulder, and knee, collectively accounting for 71.3% of the episodes of care. Patients attended a mean of 6.8 visits (SD4.7), and 63.9% experienced an improved outcome. Episodes of care for lumbar spine conditions had less reduction in pain, whereas shoulder conditions and foot/ankle conditions showed the greatest improvement. Care for hip conditions was least likely to result in an improved outcome. Knee conditions were most likely to have an improved outcome. Care for shoulder and knee conditions had the highest number of visits. Factors associated with greater reduction in pain and improved outcomes included greater initial pain or disability and attending more visits. Factors associated with greater utilization included a postsurgical condition and higher initial pain rating. Limitations. The study was performed in one geographic region within a single health care delivery system. Conclusion. The results provide information on outcomes of physical therapy or Medicare beneficiaries in one health care system. Further research is needed to examine optimal utilization and care for these patients. [ABSTRACT FROM AUTHOR]
