RESUMO
PURPOSE: The management of incidentally discovered meningioma remains controversial. We sought to compare outcomes following surgical resection of incidental meningioma to a matched cohort of symptomatic meningiomas. METHODS: A retrospective single-center case-control study was conducted for patients undergoing resection of incidental meningioma from 2000 to 2019. A 1:1 case-control matching for incidental and symptomatic meningioma was performed using the following variables: age at initial visit, gender, tumor location/size, and presence of peritumoral edema. Primary outcomes included (1) WHO grading/histopathological subtype/MIB-1 index, (2) extent of resection (gross total resection or subtotal resection), and (3) recurrence. Outcomes were compared between groups using descriptive/bivariate analyses. RESULTS: A total of 91 incidental meningiomas were analyzed. Trauma was the most common reason (n = 19, 21%) to obtain imaging, and tumor size the leading reason to operate (n = 37, 41%). Median time-to-surgery from initial clinical encounter was 5-months (Q1:3, Q3:16.5). More incidental meningioma patients (n = 47, 52%) were privately insured compared to their matched symptomatic cohort (n = 30, 33%) (P = 0.006). Patients with incidental meningioma had significantly higher mean Karnofsky Performance Scale at time-of-surgery (93.2, SD:11.1 vs. 81.4, SD:12.7) (P < 0.001). There were no significant differences in primary/secondary outcomes between the groups. Incidental meningioma was not associated with recurrence on Cox proportional hazards analysis (HR: 0.795, 95%CI: 0.3-2.1, P = 0.637). CONCLUSION: Matched case-control analysis demonstrated no significant differences in clinical, histopathological, and functional outcomes following resection of incidental and symptomatic meningioma. While non-operative management with close follow-up and serial imaging is preferred for incidental meningiomas, those undergoing resection when indicated can anticipate similar safety and efficacy as symptomatic meningiomas.

INTRODUCTION: Cystic meningiomas are rare, accounting for 2-7% of all intracranial meningiomas. Little is known regarding whether these meningiomas behave differently compared to solid meningiomas. We sought to study this relatively uncommon imaging appearance of meningioma and to evaluate its clinical significance. METHODS: A single-institution retrospective cohort study of surgically-treated meningioma patients between 2000 and 2019 was conducted. Cystic meningioma was defined as a tumor with an intratumoral or peritumoral cyst present on preoperative imaging. Demographics, preoperative imaging, histopathology characteristics, operative data, and surgical outcomes were reviewed. Imaging variables, histopathology and outcomes were reported for cystic meningiomas and compared with non-cystic meningiomas. Univariate/multivariable analyses were conducted. RESULTS: Of 737 total meningiomas treated surgically, 38 (5.2%) were cystic. Gross total resection (GTR) was achieved in 84.2% of cystic meningioma patients. Eighty-two percent of cystic meningiomas were WHO grade I (n = 31), 15.7% were grade II and 2.6% were grade III. Most cystic meningiomas had low Ki-67/MIB-1 proliferation index (n = 24, 63.2%). A total of 18.4% (n = 7) patients with cystic meningioma had recurrence compared to 12.2% (n = 80) of patients with non-cystic meningioma (p = 0.228). No significant difference in median time to recurrence was observed between cystic and non-cystic meningiomas (25.4, Q1:13.9, Q3:46.9 months vs. 13.4, Q1:8.6, Q3:35.5 months, p = 0.080). CONCLUSIONS: A small portion of intracranial meningiomas have cystic characteristics on imaging. Cystic meningiomas are frequently WHO grade I, have low proliferation index, and had similar outcomes compared to non-cystic meningioma. Cysts in meningioma may not be a surrogate to determine aggressive meningioma behavior.

OBJECTIVE: Understanding the impact of the social determinants of health on the utilization of healthcare resources is an important step in eliminating inequalities. The goal of this study was to determine the role of social determinants of health in referral patterns, timing of consultation/intervention, and quality of life in children with Chiari malformation type I (CM-I). METHODS: A retrospective study was conducted of children aged 0 to 18 years who underwent surgical treatment for CM-I at a single pediatric facility from 2015 to 2019. The variables included demographic and socioeconomic characteristics, referral patterns, timing, and quality of life data based on the Chiari Health Index for Pediatrics (CHIP). RESULTS: The cohort consisted of 103 surgically treated CM-I patients. No differences were seen in race, sex, insurance, or household income when evaluating referral source (community, specialist, or emergency department) or when comparing patients with incidental versus symptomatic findings. In the evaluation of timing from initial evaluation to surgery, no statistical differences were seen between racial, sex, insurance status, or income groups. Children from households of lower median family income were significantly more likely to report pain at the time of consultation (pain group median [interquartile range] $46,660 [$41,004-$50,367] vs nonpain group $53,604 [$41,427-$59,828], p = 0.004). Those in the lower-income group also reported lower CHIP scores corresponding to increased symptomatology in the nonpain physical symptoms (p = 0.004) and psychosocial domains (p = 0.018). CONCLUSIONS: There was no evidence of a difference in referral patterns or a delay in time from clinic presentation to surgery based on the traditional social determinants of health categories. Children from households in the lower-income group were associated with increased severity of pain and nonpain symptoms.

OBJECTIVE: Excision of intracranial meningiomas often requires resection or coagulation of the dura mater. The choice of dural closure technique is individualized and based on surgeon preference. The objective of this study was to determine outcomes following various dural closure techniques for supratentorial meningiomas. METHODS: A retrospective, single-center cohort study was performed for patients who underwent excision of supratentorial meningiomas from 2000 to 2019. Outcomes including operative time, postoperative in-hospital complications, readmission, causes of readmission including surgical site infection, pseudomeningocele, need for shunt surgery, and imaging appearance of pseudomeningocele on long-term follow-up imaging were compared. Univariate and multivariable analyses were conducted. RESULTS: A total of 353 patients who had complete clinical and operative data available for review were included. Of these patients, 227 (64.3%) had nonsutured dural graft reconstruction and 126 (35.7%) had sutured dural repair, including primary closure, artificial dura, or pericranial graft. There was significant variability in using nonsutured dural reconstruction compared with sutured dural repair technique among surgeons (p < 0.001). Tumors with sagittal sinus involvement were more likely to undergo nonsutured closure (n = 79, 34.8%) than dural repair (n = 26, 20.6%) (p = 0.003). There were no other differences in preoperative imaging findings or WHO grade. Frequency of surgical site infection and pseudomeningocele, need for shunt surgery, and recurrence were similar between those undergoing nonsutured and those undergoing sutured dural repair. The mean operative time for the study cohort was 234.9 (SD 106.6) minutes. The nonsutured dural reconstruction group had a significantly shorter mean operative time (223.9 [SD 99.7] minutes) than the sutured dural repair group (254.5 [SD 115.8] minutes) (p = 0.015). In a multivariable linear regression analysis, after controlling for tumor size and sinus involvement, nonsutured dural graft reconstruction was associated with a 36.8-minute reduction (95% CI -60.3 to -13.2 minutes; p = 0.002) in operative time. CONCLUSIONS: Dural reconstruction using a nonsutured graft and sutured dural repair exhibit similar postoperative outcomes for patients undergoing resection for supratentorial meningiomas. Although sutured grafts may sometimes be necessary, nonsutured graft reconstruction for most supratentorial meningioma resections may suffice. The decreased operative time associated with nonsutured grafts may ultimately result in cost savings. These findings should be taken into consideration when selecting a dural reconstruction technique for supratentorial meningioma.

BACKGROUND: Recurrence after meningioma resection warrants serial surveillance imaging, but little evidence guides the optimal time interval between imaging studies/surveillance duration. OBJECTIVE: To describe recurrence-free survival (RFS) after meningioma resection, conditioned to short-term RFS. METHODS: A retrospective cohort study for adults presenting for meningioma resection from 2000 to 2018 was conducted. The primary outcome was postoperative follow-up RFS. Conditional RFS Kaplan-Meier analysis was performed at 1, 2, 3, 5, and 10 years, conditioned to 6-month and 12-month RFS. RFS probabilities conditioned to 6-month RFS were estimated in subgroups, stratified by World Health Organization grade, extent of resection, and need for postoperative radiation. RESULTS: In total, 723 patients were included. Median age at surgery was 57.4 years (IQR = 47.2-67.2). Median follow-up was 23.5 months (IQR = 12.3-47.8). Recurrence was observed in 90 patients (12%), with median time to recurrence of 14.4 months (IQR = 10.3-37.1). Conditioned to 6-month postoperative RFS, patients had 90.3% probability of remaining recurrence-free at 2 years and 69.4% at 10 years. Subgroup analysis conditioned to 6-month RFS demonstrated grade 1 meningiomas undergoing gross total resection (GTR) had 96.0% probability of RFS at 1 year and 82.8% at 5 years, whereas those undergoing non-GTR had 94.5% and 79.9% probability, respectively. RFS probability was 78.8% at 5 years for non-grade 1 meningiomas undergoing GTR, compared with 69.7% for non-grade 1 meningiomas undergoing non-GTR. Patients with non-grade 1 meningiomas undergoing upfront radiation had a 1-year RFS of 90.1% and 5-year RFS of 51.7%. CONCLUSION: Recurrence risk after meningioma resection after an initial recurrence-free period is reported, with high-risk subgroups identified. These results can inform objective shared decision-making for optimal follow-up.

INTRODUCTION: Meningiomas have varying degrees of aggressive behavior. Some systemic hematologic makers are associated with malignancy, but their value in predicting aggressive meningioma behavior is not fully understood. OBJECTIVE: To evaluate the association between preoperative markers such as neutrophil-lymphocyte ratio (NLR), neutrophil-monocyte ratio (NMR), monocyte-lymphocyte ratio (MLR), platelet-lymphocyte ratio (PLR), and prognostic nutritional index (PNI), and diagnostic and prognostic factors including WHO grade, proliferation index, presence of edema on preoperative MRI, and tumor recurrence. METHODS: A retrospective review of patients treated between 2000 and 2019 with a preoperative complete blood count (CBC) differential lab draw before intracranial meningioma resection was conducted. All preoperative steroid dosages were converted to dexamethasone equivalents. Primary outcomes included presence/absence of perilesional edema, WHO grade, Ki-67/MIB-index, and recurrence. Univariate and multivariable regression analyses were conducted. RESULTS: A total of 209 meningioma patients were included. Of these, 143 (68 %) were WHO grade I, 61 (29 %) grade II and 5 (2 %) were grade III. Recurrence was reported in 19 (9.1 %) tumors. No hematologic markers were associated with recurrence. In separate multivariable logistic analyses, no biomarkers were associated with perilesional edema or WHO grade. MLR was associated with higher MIB-index (p = 0.018, OR 6.57, 95 % CI 1.37-30.91). CONCLUSION: Most hematologic markers were not associated with meningioma invasiveness, grade, proliferative index, or aggressiveness. Preoperative MLR was associated with high proliferation index in patients undergoing surgery for intracranial meningioma. Higher MLR could be a surrogate for meningioma proliferation and has potential to be used as an adjunct for risk-stratifying meningiomas.

INTRODUCTION: Glioblastoma (GBM) is the most common and deadly adult brain tumor. Red blood cell distribution width (RDW) has been found in non-central nervous system neoplasms to be associated with survival. This study aims to assess the prognostic value of pre-operative RDW and trends in RDW over time during the disease course. METHODS: This single-institution retrospective cohort study identified patients ≥â¯18 years old with pathology-proved glioblastoma treated between April 2003-May 2017 from an institutional database. A Cox proportional hazards model was developed using known prognostic clinical variables to predict overall survival time; a second model incorporating continuously valued RDW was then created. The additional prognostic value of RDW was assessed with a joint model F-test. The variation of RDW-CV over time was evaluated with linear mixed model of RDW. A post-hoc exploratory analysis was performed to assess the trend in RDW lab value leading up to time of death. RESULTS: 346 adult GBM patients were identified; complete survival data was available for all patients. The addition of RDW to the multivariable Cox proportional hazards model did not increase prognostic value. There was an upward trend in RDW throughout the post-operative disease course. In a post-hoc analysis, there was an upward trend in RDW leading up to the time of death. CONCLUSION: Although RDW has been prognostic of survival for many inflammatory, prothrombotic, and neoplastic diseases, pre-operative RDW was not associated with overall survival in GBM patients. RDW trended upwards throughout the disease course, suggesting possible systemic inflammatory effects of either glioblastoma or treatment.

BACKGROUND: Loss to follow-up (LTF) and unplanned readmission are barriers to recovery after acute subdural hematoma evacuation. The variables associated with these postdischarge events are not fully understood. OBJECTIVE: To determine factors associated with LTF and unplanned readmission, emphasizing socioeconomic status (SES). METHODS: A retrospective analysis was conducted of surgical patients with acute subdural hematoma managed operatively from 2009 to 2019 at a level 1 regional trauma center. Area Deprivation Index (ADI), which is a neighborhood-level composite socioeconomic score, was used to measure SES. Higher ADI corresponds to lower SES. To decrease the number of covariates in the model, principal components (PCs) analysis was used. Multivariable logistic regression analyses of PCs were performed for LTF and unplanned readmission. RESULTS: A total of 172 patients were included in this study. Thirty-six patients (21%) were LTF, and 49 (28%) patients were readmitted; 11 (6%) patients were both LTF and readmitted ( P = .9). The median time to readmission was 10 days (Q1: 4.5, Q3: 35). In multivariable logistic regression analyses for LTF, increased ADI and distance to hospital through PC2 (odds ratio [OR] 1.49; P = .009) and uninsured/Medicaid status and increased length of stay through PC4 (OR 1.73; P = .015) significantly contributed to the risk of LTF. Unfavorable discharge functional status and nonhome disposition through PC3 were associated with decreased odds of unplanned readmission (OR = 0.69; P = .028). CONCLUSION: Patients at high risk for LTF and unplanned readmissions, as identified in this study, may benefit from targeted resources individualized to their needs to address barrier to follow-up and to ensure continuity of care.

BACKGROUND: Acute subdural hematoma is a neurosurgical emergency. Thrombocytopenia poses a management challenge for these patients. We aimed to determine the impact of thrombocytopenia on preoperative hemorrhage expansion and postoperative outcomes. METHODS: This retrospective study evaluated patients presenting at our institution with acute subdural hematoma between 2009 and 2019. Patients who underwent surgery, had thrombocytopenia (platelets <150,000/µL), and had multiple preoperative computed tomography scans were included. Case control 1:1 matching was performed to generate a matched cohort with no thrombocytopenia. Univariate analyses were conducted to determine changes in subdural thickness and midline shift, postoperative Glasgow Coma Scale score, mortality, length of stay, and readmission rates. RESULTS: We identified 19 patients with both thrombocytopenia and multiple preoperative computed tomography scans. Median platelet count was 112,000/µL (Q1 69,000, Q3 127,000). Comparing the thrombocytopenia cohort with the control group, there was a statistically significant difference in change in subdural thickness (median 5 mm [Q1 2, Q3 7.4] vs. 0 mm [Q1 0, Q3 1.5]; P = 0.001) and change in midline shift (median 3 mm [Q1 0, Q3 9.5] vs. median 0.5 mm [Q1 0, Q3 1.5]; P = 0.018). The thrombocytopenia cohort had higher in-hospital mortality (10 [52.6%] vs. 2 [10.5%]; P = 0.003). No significant differences were found in postoperative Glasgow Coma Scale score, length of stay, number of readmissions, and number of reoperations. CONCLUSIONS: Thrombocytopenia is significantly associated with expansion of hematoma preoperatively in patients with acute subdural hematoma. While the benefit of early platelet correction cannot be determined from this study, patients who present with thrombocytopenia will benefit from close monitoring, a low threshold to obtain repeat imaging, and anticipating early surgical evacuation after platelet optimization.

BACKGROUND: By stabilizing immature leaky vessel formation in neomembranes, statin drugs have been suggested as a nonsurgical treatment option for chronic subdural hematomas (cSDH). Statin therapy seems to reduce conservatively managed cSDH volume. However, the usefulness of these medications in supplementing surgical treatment is unknown. OBJECTIVE: To investigate the effect of concurrent statin therapy on outcomes after surgical treatment of cSDH. METHODS: A retrospective single-institution cohort study of surgically managed patients with convexity cSDH between 2009 and 2019 was conducted. Patients receiving this diagnosis who underwent surgical decompression were included, and those without follow-up scans were excluded. Demographic, clinical, and radiographic variables were collected. cSDH size was defined as maximum radial thickness in millimeters on axial computed tomography of the head. Multivariable linear regression was performed to identify factors (including statin use) that were associated with preoperative to follow-up cSDH size change. RESULTS: Overall, 111 patients, including 36 patients taking statins on admission, were evaluated. Median time to follow-up postoperative imaging was 30 days (interquartile range, 17-42 days). Patients on statins were older (median, 75 years, range, 68-78.25 years vs. 69 years, range, 59-7 years; P = 0.006) and reported more antiplatelet use (67% vs. 28%; P < 0.001). Median change in follow-up size was 13 mm in both statin and nonstatin groups. Adjusting for other clinical covariates, statin use was associated with greater reduction in cSDH size (CE = -6.72 mm, 95% confidence interval, -13.18 to -0.26 mm; P = 0.042). CONCLUSIONS: Statin use is associated with improved cSDH size postoperatively. Statin drugs might represent a low-cost and low-risk supplement to the surgical management for patients with cSDH.

BACKGROUND: Lost to follow-up (LTF) represents an understudied barrier to effective management of chronic subdural hematoma (cSDH). Understanding the factors associated with LTF after surgical treatment of cSDH could uncover pathways for quality improvement efforts and modify discharge planning. We sought to identify the demographic and clinical factors associated with patient LTF. METHODS: A single-institution, retrospective cohort study of patients treated surgically for convexity cSDH from 2009 to 2019 was conducted. The primary outcome was LTF, with neurosurgical readmission as the secondary outcome. Univariate analysis was conducted using the student-t test and χ2 test. Multivariate logistic regression was performed to identify the factors associated with LTF and neurosurgical readmission. RESULTS: A total of 139 patients were included, 29% of whom were LTF. The mean first postoperative follow-up duration was 60 days. On univariate analysis, uninsured/Medicaid coverage was associated with increased LTF compared with private insurance/Medicare coverage (62.5% vs. 41.4%; P = 0.039). A higher discharge modified Rankin scale score was also associated with LTF (3.7 vs. 3.5; P < 0.001). On multivariate analysis, uninsured/Medicaid patients had a significantly greater risk of LTF compared with private insurance/Medicare patients (odds ratio, 2.44; 95% confidence interval, 1.13-5.23; P = 0.022). LTF was independently associated with an increased risk of neurosurgical readmission (odds ratio, 1.94; 95% confidence interval, 1.17-3.24; P = 0.011). CONCLUSIONS: Uninsured and Medicaid patients had a greater likelihood of LTF compared with private insurance and Medicare patients. LTF was further associated with an increased risk of neurosurgical readmission. The results from the present study emphasize the need to address barriers to follow-up to reduce readmission after surgery for cSDH. These findings could inform improved discharge planning, such as predischarge repeat imaging studies and postdischarge contact.

OBJECTIVE: The authors' previously published work validated the Chiari Health Index for Pediatrics (CHIP), a new instrument for measuring health-related quality of life (HRQOL) for pediatric Chiari malformation type I (CM-I) patients. In this study, the authors further evaluated the CHIP to assess HRQOL changes over time and correlate changes in HRQOL to changes in symptomatology and radiological factors in CM-I patients who undergo surgical intervention. Strong HRQOL evaluation instruments are currently lacking for pediatric CM-I patients, creating the need for a standardized HRQOL instrument for this patient population. This study serves as the first analysis of the CHIP instrument's effectiveness in measuring short-term HRQOL changes in pediatric CM-I patients and can be a useful tool in future CM-I HRQOL studies. METHODS: The authors evaluated prospectively collected CHIP scores and clinical factors of surgical intervention in patients younger than 18 years. To be included, patients completed a baseline CHIP captured during the preoperative visit, and at least 1 follow-up CHIP administered postoperatively. CHIP has 2 domains (physical and psychosocial) comprising 4 components, the 3 physical components of pain frequency, pain severity, and nonpain symptoms, and a single psychosocial component. Each CHIP category is scored on a scale, with 0 indicating absent and 1 indicating present, with higher scores indicating better HRQOL. Wilcoxon paired tests, Spearman correlations, and linear regression models were used to evaluate and correlate HRQOL, symptomatology, and radiographic factors. RESULTS: Sixty-three patients made up the analysis cohort (92% Caucasian, 52% female, mean age 11.8 years, average follow-up time 15.4 months). Dural augmentation was performed in 92% of patients. Of the 63 patients, 48 reported preoperative symptoms and 42 had a preoperative syrinx. From baseline, overall CHIP scores significantly improved over time (from 0.71 to 0.78, p < 0.001). Significant improvement in CHIP scores was seen in patients presenting at baseline with neck/back pain (p = 0.015) and headaches (p < 0.001) and in patients with extremity numbness trending at p = 0.064. Patients with syringomyelia were found to have improvement in CHIP scores over time (0.75 to 0.82, p < 0.001), as well as significant improvement in all 4 components. Additionally, improved CHIP scores were found to be significantly associated with age in patients with cervical (p = 0.009) or thoracic (p = 0.011) syrinxes. CONCLUSIONS: The study data show that the CHIP is an effective instrument for measuring HRQOL over time. Additionally, the CHIP was found to be significantly correlated to changes in symptomatology, a finding indicating that this instrument is a clinically valuable tool for the management of CM-I.

OBJECTIVE: The number of unsolicited patient complaints (UPCs) about surgeons correlates with surgical complications and malpractice claims. Using a large, national patient complaint database, the authors sought to do the following: 1) compare the rates of UPCs for neurosurgeons to those for other physicians, 2) analyze the risk of UPCs with individual neurosurgeon characteristics, and 3) describe the types of UPCs made about neurosurgeons. METHODS: Patient and family complaint reports among 36,265 physicians, including 423 neurosurgeons, 8292 other surgeons, and 27,550 nonsurgeons who practiced at 33 medical centers (22 academic and 11 regional) from January 1, 2014, to December 31, 2017, were coded with a previously validated Patient Advocacy Reporting System (PARS) algorithm. RESULTS: Among 423 neurosurgeons, 93% were male, and most (71%) practiced in academic medical centers. Neurosurgical subspecialties included general practice (25%), spine (25%), tumor (16%), vascular (13%), functional (10%), and pediatrics (10%). Neurosurgeons had more average total UPCs per physician (8.68; 95% CI 7.68-9.67) than nonsurgeons (3.40; 95% CI 3.33-3.47) and other surgeons (5.01; 95% CI 4.85-5.17; p < 0.001). In addition, a significantly higher percentage of neurosurgeons received at least one UPC (71.6%; 95% CI 67.3%-75.9%) than did nonsurgeons (50.2%; 95% CI 49.6%-50.8%) and other surgeons (58.2%; 95% CI 57.1%-59.3%; p < 0.001). Factors most associated with increased average UPCs were younger age, measured as median medical school graduation year (1990.5 in the 0-UPC group vs 1993 in the 14+-UPC group, p = 0.009) and spine subspecialty (13.4 mean UPCs in spine vs 7.9 mean UPCs in other specialties, 95% CI 2.3-8.5, p < 0.001). No difference in complaints was seen in those who graduated from non-US versus US medical schools (p = 0.605). The most common complaint types were related to issues surrounding care and treatment, communication, and accessibility, each of which was significantly more common for neurosurgeons than other surgical specialties (p < 0.001). CONCLUSIONS: Neurosurgeons were more likely to generate UPCs than other surgical specialties, and almost 3 out of 4 neurosurgeons (71.6%) had at least one UPC during the study period. Prior studies have shown that feedback to physicians about behavior can result in fewer UPCs. These results suggest that neurosurgeons have opportunities to reduce complaints and potentially improve the overall quality of care delivered.

OBJECTIVE Many patients undergoing spinal fusion for neuromuscular scoliosis have preexisting neurosurgical implants, including ventricular shunts (VSs) for hydrocephalus and baclofen pumps (BPs) for spastic cerebral palsy. Recent studies have discussed a possible increase in implant complication rates following spinal fusion, but published data are inconclusive. The authors therefore, sought to investigate: 1) the rate of implant complications following fusion, 2) possible causes of these complications, and 3) factors that place patients at higher risk for implant-related complications. METHODS Cases involving pediatric patients with a preexisting VS or BP who underwent spinal fusion for scoliosis correction between 2005 and 2016 at a single tertiary children's hospital were retrospectively analyzed. Patient demographics, implant characteristics, spinal fusion details, neurosurgical follow-up, and implant complications in the 180 days following fusion were recorded and analyzed. RESULTS Overall, 75 patients who underwent scoliosis correction had preexisting implants: 39 had BPs, 31 VSs, and 5 both. The patients' mean age at fusion was 13.49 ± 2.78 years (range 3.62-18.81 years), and the mean time from the most recent previous implant surgery to fusion was 5.70 ± 4.65 years (range 0.10-17.3 years). The mean preoperative and postoperative Cobb angles were 62.4° ± 18.9° degrees (range 20.9°-109.0°) and 23.5° ± 13.3° degrees (range 2.00°-67.3°), respectively. No VS complications were identified. Two patients with BPs were found to have complications (unintentional cutting of their BP catheter during posterior spinal fusion) within 180 days postfusion. There were no recorded neurosurgical implant infections, failures, fractures, or dislodgements. Although 10 patients required at least 1 surgical procedure for irrigation and debridement of the spine wound following fusion, there were no abdominal or cranial implant wound infections requiring revision, and no implants required removal. CONCLUSIONS The results of this study suggest that spinal fusion for scoliosis correction does not increase the rates of complications involving previously placed neurosurgical implants. A large-scale, prospective, multicenter study is needed to fully explore and confirm this finding.

OBJECTIVE Readmission and return to operating room after surgery are increasingly being used as a proxy for quality of care. Nearly 60% of these readmissions are unplanned, which translates into billions of dollars in health care costs. The authors set out to analyze the incidence of readmission at their center, to define causes of unplanned readmission, and to determine the preoperative and surgical variables associated with readmissions following pediatric neurosurgery. METHODS A total of 536 children who underwent operations for neurosurgical diagnoses between 2012 and 2015 and who were later readmitted were included in the final analysis. Unplanned readmissions were defined to have occurred as a result of complications within 90 days after index surgery. Patient records were retrospectively reviewed to determine the primary diagnosis, surgery indication, and cause of readmission and return to operating room. The cost for index hospitalization, readmission episode, and total cost were derived based on the charges obtained from administrative data. Bivariate and multivariable analyses were conducted. RESULTS Of 536 patients readmitted in total, 17.9% (n = 96) were readmitted within 90 days. Of the overall readmissions, 11.9% (n = 64) were readmitted within 30 days, and 5.97% (n = 32) were readmitted between 31 and 90 days. The median duration between discharge and readmission was 20 days (first quartile [Q1]: 9 days, third quartile [Q3]: 36 days). The most common reason for readmission was shunt related (8.2%, n = 44), followed by wound infection (4.7%, n = 25). In the risk-adjusted multivariable logistic regression model for total 90-day readmission, patients with the following characteristics: younger age (p = 0.001, OR 0.886, 95% CI 0.824-0.952); "other" (nonwhite, nonblack) race (p = 0.024, OR 5.49, 95% CI 1.246-24.2); and those born preterm (p = 0.032, OR 2.1, 95% CI 1.1-4.12) had higher odds of being readmitted within 90 days after discharge. The total median cost for patients undergoing surgery in this study cohort was $11,520 (Q1: $7103, Q3: $19,264). For the patients who were readmitted, the median cost for a readmission episode was $8981 (Q1: $5051, Q3: $18,713). CONCLUSIONS Unplanned 90-day readmissions in pediatric neurosurgery are primarily due to CSF-related complications. Patients with the following characteristics: young age at presentation; "other" race; and children born preterm have a higher likelihood of being readmitted within 90 days after surgery. The median cost was > $8000, which suggests that the readmission episode can be as expensive as the index hospitalization. Clearly, readmission reduction has the potential for significant cost savings in pediatric neurosurgery. Future efforts, such as targeted education related to complication signs, should be considered in the attempt to reduce unplanned events. Given the single-center, retrospective study design, the results of this study are primarily applicable to this population and cannot necessarily be generalized to other institutions without further study.
