Effect of Early Rehabilitation Treatment on Activities of Daily Living in Patients Receiving Conservative Treatment for Vertebral Compression Fracture.

OBJECTIVES

: Vertebral compression fractures are common among older people. Currently, knowledge of the effects of early rehabilitation treatment on the recovery of activities of daily living (ADL) in older patients who receive conservative treatment for these fractures is limited. Using the instrumental variable (IV) method, we examined the effects on ADL at discharge of a delay in initiating rehabilitation treatment.

METHODS

In this retrospective cohort study, data from the Japanese Diagnosis Procedure Combination database were analyzed. The subjects were patients with vertebral compression fracture who had undergone rehabilitation treatment during their hospitalization between 2014 and 2019 in one of the 29 acute-care hospitals in Yamagata Prefecture. We analyzed data from 1706 patients (mean age, 82.1 years). The independent variable was the number of days between hospital admission and the start of rehabilitation treatment, and the outcome was the Barthel index (BI) score at discharge. An IV method was applied, with adjustments for covariates, including demographics and functional status at admission.

RESULTS

Most patients started rehabilitation treatment within 3 days of hospital admission. Our IV method showed that the interval between hospital admission and the start of rehabilitation treatment was significantly associated with the BI score at discharge. The coefficient was -2.71 (95% confidence interval [CI]: -5.06 to -0.35).

CONCLUSIONS

A delay in initiating rehabilitation treatment had a negative effect on ADL at discharge. This result emphasizes the importance of including early rehabilitation treatment in acute care, as recommended by several existing guidelines for the treatment of orthopedic diseases.
