The Impact of the Amount of Rehabilitation Provision on Functional Outcome in Vertebral Compression Fractures

Abstract

Introduction: Patients with vertebral compression fractures are likely to decrease physical function and activities of daily living (ADL) due to pain and inactivity. In this study, we examined the effect of the amount of rehabilitation provided on functional prognosis in patients with vertebral compression fracture.

Methods: We included 18,174 vertebral compression fracture patients aged 65 years or older in the JMDC multicenter data. Barthel index (BI) gains, BI efficiency, ADL independence at discharge (BI≧95), and discharge home were compared between patients who received an average of at least 1 unit of rehabilitation during hospitalization (high-provider group) and those who received less than 1 unit per day (low-provider group).

Results: There were 4,145 patients in the high-provider group and 14,029 in the low-provider group. The high-provider group had higher BI gain and BI efficiency, as well as a higher percentage of patients with independent ADLs at discharge (41.6%) and a higher percentage of patients discharged home (79.2%). In multiple regression analysis, the high-provider group had higher BI gain (regression coefficient: 2.423) and BI efficiency (regression coefficient: 0.043). Multiple logistic regression analysis showed that the high-provider group had a higher rate of discharge home (odds ratio: 1.26) and a higher rate of ADL independence at discharge (odds ratio: 1.17).

Conclusion: In patients with vertebral compression fractures, the amount of rehabilitation provision may have an impact on functional prognosis.
