Factors Affecting the Discharge Destination of Patients With Spinal Bone Metastases

To investigate the factors affecting the discharge destination of patients with spinal bone metastases.

We reviewed the medical records of patients admitted to our institute with a diagnosis of skeletalrelated events secondary to malignant disease. Exclusion criteria comprised decreased cognitive function and hypercalcemia, brain metastasis, peritoneal dissemination, and pleural dissemination. The factors examined included the discharge destination, age, sex, the Barthel Index (BI) at admission and discharge, pain at admission and discharge, number of co-resident household members, length of hospital stay, treatment strategy, spinal instability neoplastic score, vertebral body collapse, spinal level of bone metastases, and motor paralysis. For the discharge destination, patients at discharge were grouped into two categories. The home group included patients discharged to their own homes, and the non-home group included patients discharged to other hospitals.

Of 140 patients, the home group comprised 120 patients and the non-home group comprised 20 patients. Activities of daily living (ADL) and pain at rest and during motion improved significantly in the home group, whereas only pain at rest and during motion improved significantly in the non-home group. The results indicated that discharge BI and motor paralysis were the best predictors of the discharge destination; a BI cut-off value of 72.5 predicted discharge to home.

This study showed that the ADL level on discharge and motor paralysis affected the discharge destination of patients with spinal bone metastases. These results are likely to be helpful in predicting the discharge destination of patients with spinal bone metastases.
