Endoscopic and Nonendoscopic Approaches to Single-Level Lumbar Spine Decompression: Propensity Score-Matched Comparative Analysis and Frailty-Driven Predictive Model
Objective The endoscopic spine surgery (ESS) approach is associated with high levels of patient satisfaction, shorter recovery time, and reduced complications. The present study reports multicenter, international data, comparing ESS and non-ESS approaches for single-level lumbar decompression, and proposes a frailty-driven predictive model for nonhome discharge (NHD) disposition. Methods Cases of ESS and non-ESS lumbar spine decompression were queried from the American College of Surgeons National Surgical Quality Improvement Program database (2017β2020). Propensity score matching was performed on baseline characteristics frailty score (measured by risk analysis index [RAI] and modified frailty index-5 [mFI-5]). The primary outcome of interest was NHD disposition. A predictive model was built using logistic regression with RAI as the primary driver. Results Single-level nonfusion spine lumbar decompression surgery was performed in 38,686 patients. Frailty, as measured by RAI, was a reliable predictor of NHD with excellent discriminatory accuracy in receiver operating characteristic (ROC) curve analysis: C-statistic: 0.80 (95% confidence interval [CI], 0.65β0.94) in ESS cohort, C-statistic: 0.75 (95% CI, 0.73β0.76) overall cohort. After propensity score matching, there was a reduction in total operative time (89 minutes vs. 103 minutes, p = 0.049) and hospital length of stay (LOS) (0.82 days vs. 1.37 days, p < 0.001) in patients treated endoscopically. In ROC curve analysis, the frailty-driven predictive model performed with excellent diagnostic accuracy for the primary outcome of NHD (C-statistic: 0.87; 95% CI, 0.85β0.88). Conclusion After frailty-based propensity matching, ESS is associated with reduced operative time, shorter hospital LOS, and decreased NHD. The RAI frailty-driven model predicts NHD with excellent diagnostic accuracy and may be applied to preoperative decision-making with a user-friendly calculator: nsgyfrailtyoutcomeslab.shinyapps.io/lumbar_decompression_dischargedispo
Trends in United States pediatric neurosurgical practice during the COVID-19 pandemic
There is minimal information on COVID-19 pandemic\u27s national impact on pediatric neurosurgical operative volumes. In this study, using a national database, TriNetX, we compared the overall and seasonal trends of pediatric neurosurgical procedure volumes in the United States during the pandemic to pre-pandemic periods. In the United States, the incidence of COVID-19 began to rise in September 2020 and reached its maximum peak between December 2020 and January 2021. During this time, there was an inverse relationship between pediatric neurosurgical operative volumes and the incidence of COVID-19 cases. From March 2020 to May 2021, there was a significant decrease in the number of pediatric shunt (β11.7% mean change, p = 0.006), epilepsy (β16.6%, p \u3c 0.001), and neurosurgical trauma (β13.8%, p \u3c 0.001) surgeries compared to pre-pandemic years. The seasonal analysis also yielded a broad decrease in most subcategories in spring 2020 with significant decreases in pediatric spine, epilepsy, and trauma cases. To the best of our knowledge, this is the first study to report a national decline in pediatric shunt, epilepsy, and neurosurgical trauma operative volumes during the pandemic. This could be due to fear-related changes in health-seeking behavior as well as underdiagnosis during the COVID-19 pandemic
Frailty as a Superior Predictor of Dysphagia and Surgically Placed Feeding Tube Requirement After Anterior Cervical Discectomy and Fusion Relative to Age
Frailty is a measure of physiological reserve that has been demonstrated to be a discriminative predictor of worse outcomes across multiple surgical subspecialties. Anterior cervical discectomy and fusion (ACDF) is one of the most common neurosurgical procedures in the United States and has a high incidence of postoperative dysphagia. To determine the association between frailty and dysphagia after ACDF and compare the predictive value of frailty and age. 155,300 patients with cervical stenosis (CS) who received ACDF were selected from the 2016-2019 National Inpatient Sample (NIS) utilizing International Classification of Disease, tenth edition (ICD-10) codes. The 11-point modified frailty index (mFI-11) was used to stratify patients based on frailty: mFI-11β=β0 was robust, mFI-11β=β1 was prefrail, mFI-11β=β2 was frail, and mFI-11β=β3β+βwas characterized as severely frail. Demographics, complications, and outcomes were compared between frailty groups. A total of 155,300 patients undergoing ACDF for CS were identified, 33,475 (21.6%) of whom were frail. Dysphagia occurred in 11,065 (7.1%) of all patients, and its incidence was significantly higher for frail patients (OR 1.569, pβ\u3cβ0.001). Frailty was a risk factor for postoperative complications (OR 1.681, pβ\u3cβ0.001). Increasing frailty and undergoing multilevel ACDF were significant independent predictors of negative postoperative outcomes, including dysphagia, surgically placed feeding tube (SPFT), prolonged LOS, non-home discharge, inpatient death, and increased total charges (pβ\u3cβ0.001 for all). Increasing mFI-11 score has better prognostic value than patient age in predicting postoperative dysphagia and SPFT after ACDF
