Background:
The management of elective surgeries during the COVID-19 pandemic was controversial, and the impact on lumbar spinal stenosis (LSS) surgery outcomes remains unclear. This study aimed to retrospectively analyze older adults who underwent LSS surgery during the pandemic and compare cases from its early and late phases.
Methods:
Medical records of patients aged 65 and older who underwent LSS surgery between April 2020 and April 2023 were reviewed. The Zurich Claudication Questionnaire and Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) were administered preoperatively and at 6 months and 1 year postoperatively.
Results:
The period from April 2020 to September 2021 was classified as the early phase, while October 2021 to April 2023 was classified as the late phase. This study evaluated a total of 267 older patients with LSS, with 138 undergoing surgery during the early phase and 129 during the late phase. There was one case of COVID-19 infection during hospitalization in the early phase and none in the late phase. Significant differences were found between the early and late phases in the distribution of American Society of Anesthesiologists physical status (ASA) and frequency of degenerative lumbar scoliosis (DLS). When the association between the COVID-19 pandemic phase and effective case of surgery treatment on JOABPEQ was examined, the multivariable adjusted relative risks of effective case in social life domain for the late-stage group were 0.7 (95 % CI = 0.5-0.9) at both 6 months and 1 year postoperatively using the early-phase group as the reference. No significant differences were found in the other four domains at either 6 months or 1 year postoperatively.
Conclusions:
Poorer social life outcomes in the late-phase patients with LSS surgery may be attributed to worse preoperative ASA scores and changes in social life during different pandemic phases.
