ObjectiveThe objective of this study was to verify that spine surgery for late-stage elderly (LSE) (age 65-74 years) is as safe as that for early-stage elderly (ESE) (age 65-74 years).MethodsThis retrospective multicenter study included elderly patients aged ≥65 years who underwent spine surgery between 2018 and 2021. The medical information for individual patients was obtained from medical records. Activities of daily living (ADL) were estimated using a 5-grade scale based on the Eastern Cooperative Oncology Group performance status. Good outcome was defined as ADL grade 0 or 1 at discharge; poor outcome was defined as ADL grade 2 to 4 at discharge. The postoperative complications were listed with reference to the Common Terminology Criteria for Adverse Events v5.0.ResultsThere were 311 patients in the ESE group and 395 patients in the LSE group. Reoperation during hospitalization was significantly higher in the LSE group (4.6%) than in the ESE group (1.6%). The total number of days of hospitalization was significantly longer in the LSE group than in the ESE group. However, there was no significant difference in the postoperative complications or ADL at discharge between the 2 groups. In the statistical analysis, preoperative American Society of Anesthesiologists physical status class 3-6, underlying heart or renal disease, and cervical or thoracic spine level of surgical procedures were significantly associated with poor ADL outcomes at discharge.ConclusionsSpine surgery even for LSE can be safely done, if perioperative risk factors are appropriately managed.Copyright © 2023 Elsevier Inc.
