The influence of facility type on intracranial meningioma treatment and outcomes: predicting overall survival using the National Cancer Database.

OBJECTIVE: There is a growing body of evidence demonstrating improved outcomes for patients with CNS neoplasms treated at academic centers (ACs) versus nonacademic centers (non-ACs), which represents a potential healthcare disparity within neurosurgery. In this paper, the authors sought to investigate the relationship between facility type and surgical outcomes in meningioma patients. METHODS: The National Cancer Database was queried for adult patients diagnosed with intracranial meningioma between 2004 and 2019. Patients were stratified by facility type, and the Mann-Whitney U-test and Fisher exact test were used for bivariate comparisons of continuous and categorical variables, respectively. Multivariate logistic regression was used to assess whether demographic variables were associated with treatment at ACs. Furthermore, multivariate Cox proportional hazards models were used to determine whether facility type was associated with overall survival (OS) outcomes. RESULTS: Data on 139,304 patients (74% male, 84% White) were retrieved. Patients were stratified by facility type, with 50,349 patients (36%) treated at ACs and 88,955 patients (64%) treated at non-ACs. Patients treated at ACs were more likely to have private insurance (41% vs 34%, p < 0.001) and less likely to have Medicare (46% vs 57%, p < 0.001). Patients treated at ACs were more likely to have larger tumors (36.91 mm vs 33.57 mm, p < 0.001) and more likely to undergo surgery (47% vs 34%, p < 0.001). Interestingly, patients treated at ACs had decreased comorbidities (Charlson Comorbidity Index rating 0: 74% vs 69%) and similar income levels (income ≥ $46,000: 44% vs 43%). With respect to survival outcomes, patients treated at ACs demonstrated a higher median OS at 10 years than patients treated at non-ACs (65.2% vs 54.1%). The association of improved OS in patients treated at ACs continued to be true when adjusting for all other clinical and demographic variables (HR 0.900, 95% CI 0.882-0.918; p < 0.001). CONCLUSIONS: The results of this study indicate that facility type is associated with disparate survival outcomes in the treatment of intracranial meningiomas. Namely, patients treated at non-ACs appear to have a survival disadvantage even when controlling for additional comorbidities.

A cost analysis of medical students applying to neurological surgery residency: An analysis of the Texas STAR database.

INTRODUCTION: Medical Students applying to neurosurgery residency programs incur substantial costs associated with interviews, away rotations, and application fees. However, few studies have compared expenses prior to and during the COVID-19 pandemic. This study evaluates the financial impact of COVID-19 on the neurosurgery residency application and identifies strategies that may alleviate the financial burden of prospective neurosurgery residents. METHODS: The TEXAS STAR database was surveyed for applicants of neurosurgical residency programs during the COVID-19 pandemic (2021) and post-pandemic (2022). 66 applicants for the 2021 application cycle and 50 applicants for the 2022 application cycle completed the survey. We compared application fees, away rotations cost, interview cost, and total expenses as reported by the neurosurgery applicants of the 2021 and 2022 application cycle. A Shapiro-Wilk test was used to test for data normality, and a Mann-Whitney U-Test was used to compare costs during the 2021 and 2022 neurosurgery application cycle. RESULTS: There was a statistically significant reduction in total expenses in 2021 vs 2022 ($3,934 vs $9,860). Interview and away rotation expenses decreased in 2021 vs 2022 (interview expenses $786 vs $4511, away rotation $1,083 vs $3,000, p < 0.001). Application fee expenses were not different between 2021 and 2022. The greatest reduction in application cost ($11,908) was seen in the South for 2021. CONCLUSIONS: The COVID-19 pandemic significantly reduced total fees associated with the neurosurgical residency application. Virtual platforms in place of in-person interviews could lessen the financial burden on applicants and alleviate socioeconomic barriers in the neurosurgical application process after COVID-19.

Retrospective single-surgeon study of prone versus lateral robotic pedicle screw placement: a CT-based assessment of accuracy.

OBJECTIVE: Lateral lumbar interbody fusion including anterior-to-psoas oblique lumbar interbody fusion has conventionally relied on pedicle screw placement (PSP) for construct stabilization. Single-position surgery with lumbar interbody fusion in the lateral decubitus position with concomitant PSP has been associated with increased operative efficiency. What remains unclear is the accuracy of PSP with robotic guidance when compared with the more familiar prone patient positioning. The present study aimed to compare robot-assisted screw placement accuracy between patients with instrumentation placed in the prone and lateral positions. METHODS: The authors identified all consecutive patients treated with interbody fusion and PSP in the prone or lateral position by a single surgeon between January 2019 and October 2022. All pedicle screws placed were analyzed using CT scans to determine appropriate positioning according to the Gertzbein-Robbins classification grading system (grade C or worse was considered as a radiographically significant breach). Multivariate logistic regression models were constructed to identify risk factors for the occurrence of a radiographically significant breach. RESULTS: Eighty-nine consecutive patients (690 screws) were included, of whom 46 (477 screws) were treated in the prone position and 43 (213 screws) in the lateral decubitus position. There were fewer breaches in the prone (n = 13, 2.7%) than the lateral decubitus (n = 15, 7.0%) group (p = 0.012). Nine (1.9%) radiographically significant breaches occurred in the prone group compared with 10 (4.7%) in the lateral decubitus group (p = 0.019), for a prone versus lateral decubitus PSP accuracy rate of 98.1% versus 95.3%. There were no significant differences in BMI between prone versus lateral decubitus cohorts (30.1 vs 29.6) or patients with screw breach versus those without (31.2 vs 29.5). In multivariate models, the prone position was the only significant protective factor for screw accuracy; no other significant risk factors for screw breach were identified. CONCLUSIONS: The present data suggest that pedicle screws placed with robotic assistance have higher placement accuracy in the prone position. Further studies will be needed to validate the accuracy of PSP in the lateral position as single-position surgery becomes more commonplace in the treatment of spinal disorders.

Cost Savings Associated with Vacuum-Assisted Closure in Trauma Patients Undergoing Posterior Spinal Fusion.

OBJECTIVE: To investigate the implications of vacuum-assisted closure (VAC) versus standard wound dressings on postoperative posterior spinal fusion (PSF) wounds with respect to potential cost savings associated with reduced incidence of surgical site infections. METHODS: This was a retrospective review of trauma patients who underwent open PSF under the care of a single surgeon at a Level I trauma center. Patients were postoperatively monitored for 90 days. Statistical analysis was performed with χ2 testing with the calculation of number needed to treat values. RESULTS: Inclusion criteria were met by 208 patients who underwent open PSF. The χ2 test revealed a significant increase in incidence of surgical site infections (20% vs. 8%; P = 0.021) in the non-VAC group (n = 112) compared with the VAC group (n = 96). Cost-benefit analysis revealed that use of VAC in patients undergoing open PSF could enable a mean cost savings of $163,492 per 100 patients. CONCLUSIONS: Use of VAC in patients undergoing open PSF was associated with a 2-fold decrease in incidence of surgical site infections and an infection-related cost savings of $163,492 per 100 patients. Further investigation is needed to ascertain additional benefits of VAC usage in patients undergoing open PSF.
