Study DesignA retrospective comparative study.ObjectiveThis study aimed to investigate factors associated with postoperative unfavorable ambulatory status following surgery for metastatic spinal tumors using a nationwide in-hospital database.Summary Of Background DataSurgical treatment for metastatic spinal tumors can improve the ambulatory status and quality of life. However, some patients fail to regain the ability to walk, thereby resulting in poor quality of life. No large-scale study has previously evaluated factors associated with postoperative poor ambulatory status in this clinical context.Materials And MethodsThe Diagnosis Procedure Combination database from 2018 to 2019 was used to extract data from patients who underwent surgical procedures for spinal metastasis. Postoperative unfavorable ambulatory status was defined as (1) nonambulatory at discharge or (2) a decreased mobility score of the Barthel Index between admission and discharge. Multivariable logistic regression was used to evaluate factors associated with postoperative unfavorable ambulatory status while adjusting for confounders.ResultsThis study analyzed 1786 eligible patients. Of whom, 1061 (59%) patients were ambulatory on admission and 1249 (70%) on discharge. Postoperative unfavorable ambulatory status was observed in 597 (33%) patients, with a significantly lower rate of discharge to home (41%/81%, P <0.001) and a longer postoperative hospital stay (46.2 days/31.4 days, P <0.001). Multivariable regression analysis revealed male sex [odds ratio (OR): 1.43, P =0.002], laminectomy without fusion (OR: 1.55, P =0.034), Charlson Comorbidity Index of ≥7 (OR: 1.37, P =0.014), and preoperative nonambulatory status (OR: 6.61, P <0.001) as factors associated with postoperative unfavorable ambulatory status.ConclusionsOur large-scale database analysis revealed that 33% of patients experienced unfavorable ambulatory status following spinal metastasis surgery. Laminectomy without fusion and preoperative nonambulatory status were among several factors influencing the prospect of unfavorable ambulatory status following surgery.Copyright © 2023 Wolters Kluwer Health, Inc.
