Measures of Health-Related Quality of Life Outcomes in Pediatric Neurosurgery: Literature Review

Background Improving value in healthcare means optimizing outcomes and minimizing costs. The emerging pay-for-performance era requires understanding of the effect of healthcare services on health-related quality of life (HRQoL). Pediatric and surgical subspecialties have yet to fully integrate HRQoL measures into practice. The present study reviewed and characterized the HRQoL outcome measures across various pediatric neurosurgical diagnoses. Methods A literature review was performed by searching PubMed and Google Scholar with search terms such as “health-related quality of life” and “pediatric neurosurgery” and then including the specific pathologies for which a HRQoL instrument was found (e.g., “health-related quality of life” plus “epilepsy”). Each measurement was evaluated by content and purpose, relative strengths and weaknesses, and validity. Results We reviewed 68 reports. Epilepsy, brain tumor, cerebral palsy, spina bifida, hydrocephalus, and scoliosis were diagnoses found in reported studies that had used disease-specific HRQoL instruments. Information using general HRQoL instruments was also reported. Internal, test–retest, and/or interrater reliability varied across the instruments, as did face, content, concurrent, and/or construct validity. Few instruments were tested enough for robust reliability and validity. Significant variability was found in the usage of these instruments in clinical studies within pediatric neurosurgery. Conclusions The HRQoL instruments used in pediatric neurosurgery are currently without standardized guidelines and thus exhibit high variability in use. Clinicians should support the development and application of these methods to optimize these instruments, promote standardization of research, improve performance measures to reflect clinically modifiable and meaningful outcomes, and, ultimately, lead the national discussion in healthcare quality and patient-centered care

Intracranial arachnoid cysts: Pediatric neurosurgery update

Background: With the greater worldwide availability of neuroimaging, more intracranial arachnoid cysts (IACs) are being found in all age groups. A subset of these lesions become symptomatic and requires neurosurgical management. The clinical presentations of IACs vary from asymptomatic to extremely symptomatic. Here, we reviewed the clinical presentation and treatment considerations for pediatric IACs. Case Description: Here, we presented three cases of IAC, focusing on different clinical and treatment considerations. Conclusion: IACs can be challenging to manage. There is no Class I Evidence to guide how these should be treated. We suggest clinical decision-making framework as to how to treat IACs based on our understanding of the natural history, risks/benefits of treatments, and outcomes in the future, require better patient selection for the surgical management of IACs will be warranted

Firearm-Related Pediatric Head Trauma: A Scoping Review.

BACKGROUND: Firearm-related injury is a significant cause of morbidity and mortality in pediatric populations. Despite a disproportionate role in the most morbid outcomes in both traumatic brain injury and firearm-related injury populations, firearm-related traumatic brain injury (frTBI) is an understudied epidemiological entity. There is need to increase understanding and promote interventions that reduce this burden of disease. OBJECTIVE: To assess the evidence characterizing pediatric frTBI to highlight trends and gaps regarding burden of disease and interventions to reduce frTBI. METHODS: We conducted a scoping review under Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Scoping Review (PRISMA-ScR) guidelines on peer-reviewed studies across 5 databases (Medline OVID, EMBASE, Web of Science Legal Collection, PsychINFO, and Academic Search Complete). English studies examining pediatric frTBI epidemiology, prevention, and/or social or legal policy advocacy were included. Articles were excluded if they more generally discussed pediatric firearm-related injury without specific analysis of frTBI. RESULTS: Six studies satisfied inclusion criteria after screening and full-text assessment. Limited studies specifically addressed the burden of disease caused by frTBI. There was an increased risk for both injury and death from frTBI in men, preteenage and teenage youths, minorities, and individuals in firearm-owning households. Further study is required to ascertain if suggested methods of targeted patient screening, firearm-injury prevention counseling, and advocacy of safety-oriented policy tangibly affect rates or outcomes of pediatric frTBI. CONCLUSION: By understanding published epidemiological data and areas of intervention shown to reduce frTBIs, neurosurgeons can become further engaged in public health and prevention rather than strictly treatment after injury

Network-Targeted Approach and Postoperative Resting-State Functional Magnetic Resonance Imaging Are Associated with Seizure Outcome

Objective Postoperative resting‐state functional magnetic resonance imaging (MRI) in children with intractable epilepsy has not been quantified in relation to seizure outcome. Therefore, its value as a biomarker for epileptogenic pathology is not well understood. Methods In a sample of children with intractable epilepsy who underwent prospective resting‐state seizure onset zone (SOZ)‐targeted epilepsy surgery, postoperative resting‐state functional MRI (rs‐fMRI) was performed 6 to 12 months later. Graded normalization of the postoperative resting‐state SOZ was compared to seizure outcomes, patient, surgery, and anatomical MRI characteristics. Results A total of 64 cases were evaluated. Network‐targeted surgery, followed by postoperative rs‐fMRI normalization was significantly (p < 0.001) correlated with seizure reduction, with a Spearman rank correlation coefficient of 0.83. Of 39 cases with postoperative rs‐fMRI SOZ normalization, 38 (97%) became completely seizure free. In contrast, of the 25 cases without complete rs‐fMRI SOZ normalization, only 3 (5%) became seizure free. The accuracy of rs‐fMRI as a biomarker predicting seizure freedom is 94%, with 96% sensitivity and 93% specificity. Interpretation Among seizure localization techniques in pediatric epilepsy, network‐targeted surgery, followed by postoperative rs‐fMRI normalization, has high correlation with seizure freedom. This study shows that rs‐fMRI SOZ can be used as a biomarker of the epileptogenic zone, and postoperative rs‐fMRI normalization is a biomarker for SOZ quiescence

Trigeminal schwannoma presenting with malocclusion: A case report and review of the literature

Background: Trigeminal schwannomas are rare tumors of the trigeminal nerve. Depending on the location, from which they arise along the trigeminal nerve, these tumors can present with a variety of symptoms that include, but are not limited to, changes in facial sensation, weakness of the masticatory muscles, and facial pain. Case Description: We present a case of a 16-year-old boy with an atypical presentation of a large trigeminal schwannoma: painless malocclusion and unilateral masticatory weakness. This case is the first documented instance; to the best of our knowledge, in which a trigeminal schwannoma has led to underbite malocclusion; it is the 19th documented case of unilateral trigeminal motor neuropathy of any etiology. We discuss this case as a unique presentation of this pathology, and the relevant anatomy implicated in clinical examination aid in further understanding trigeminal nerve pathology. Conclusion: We believe our patient’s underbite malocclusion occurred secondary to his trigeminal schwannoma, resulting in associated atrophy and weakness of the muscles innervated by the mandibular branch of the trigeminal nerve. Furthermore, understanding the trigeminal nerve anatomy is crucial in localizing lesions of the trigeminal nerve

The effectiveness of medical and surgical treatment for children with refractory epilepsy

BACKGROUND: Pediatric refractory epilepsy affects quality of life, clinical disability, and healthcare costs for patients and families. OBJECTIVE: To show the impact of surgical treatment for pediatric epilepsy on healthcare utilization compared to medically treated pediatric epilepsy over 5 yr. METHODS: The Pediatric Health Information System database was used to conduct a cohort study using 5 published algorithms. Refractory epilepsy patients treated with antiepileptic medications (AEDs) only or AEDs plus epilepsy surgery between 1/1/2008 and 12/31/2014 were included. Healthcare utilization following the index date at 2 and 5 yr including inpatient, emergency department (ED), and all epilepsy-related visits were evaluated. The propensity scores (PS) method was used to match surgically and medically treated patients. PS. SAS® 9.4 and Stata 14.0 were used for data management and statistical analysis. RESULTS: A total of 2106 (17.1%) and 10186 (82.9%) were surgically and medically treated. A total of 4050 matched cases, 2025 per each treated group, were included. Compared to medically treated patients, utilization was reduced in the surgical group: at 2 and 5 yr postindex date, there was a reduction of 36% to 37% of inpatient visits and 47% to 50% of ED visits. The total number (inpatient, ED, ambulatory visits) of epilepsy-associated visits were reduced by 39% to 43% in the surgical group compared to the medically treated group. In those who had surgery, the average reduction in AEDs was 16% at 2 and 5 yr after treatment. CONCLUSION: Patients with refractory epilepsy treated with surgery had significant reductions in healthcare utilization compared with patients treated only with medications. treated patients, surgically treated patients tend to have increased overall survival and better quality of life

Insurance transitions and healthcare utilization for children with refractory epilepsy

Objectives: The objective of the study is to investigate the association between insurance transitions and healthcare utilization among children with refractory epilepsy. Methods: We applied published algorithms to identify the study cohort of children with a diagnosis of refractory epilepsy who were treated between 10/1/2013 and 9/30/2014 at 36 children\u27s hospitals in the United States. Insurance transition was defined as having any change in the type of primary payer from the first date of diagnosis to the date of the last visit at the same hospital. Univariate and multilevel multivariable analytical methods were used in the study. Results: Among 3488 children hospitalized with refractory epilepsy, rates of insurance transitions at 1, 2, and 5 years of refractory epilepsy diagnosis were 8.1%, 14%, and 29.9%, respectively. Patients whose primary payer at diagnosis was Private or Others were more likely to experience insurance transitions than patients whose primary payer was Medicaid. Younger children were associated with a higher risk of insurance transitions than older children. The high intensity of insurance transitions was associated with a higher number of emergency department and inpatient visits. Conclusions: Insurance transitions interrupted the continuity of medical care for children with refractory epilepsy and were associated with more frequent hospitalizations and emergency department visits, which then translated to higher healthcare costs. Medicaid provided stable insurance coverage and is critically important for these patients and should be the main focus for policies aiming to minimize insurance transitions and optimize healthcare delivery

Multimodal Deep Learning-Based Prognostication in Glioma Patients: A Systematic Review

Malignant brain tumors pose a substantial burden on morbidity and mortality. As clinical data collection improves, along with the capacity to analyze it, novel predictive clinical tools may improve prognosis prediction. Deep learning (DL) holds promise for integrating clinical data of various modalities. A systematic review of the DL-based prognostication of gliomas was performed using the Embase (Elsevier), PubMed MEDLINE (National library of Medicine), and Scopus (Elsevier) databases, in accordance with PRISMA guidelines. All included studies focused on the prognostication of gliomas, and predicted overall survival (13 studies, 81%), overall survival as well as genotype (2 studies, 12.5%), and response to immunotherapy (1 study, 6.2%). Multimodal analyses were varied, with 6 studies (37.5%) combining MRI with clinical data; 6 studies (37.5%) integrating MRI with histologic, clinical, and biomarker data; 3 studies (18.8%) combining MRI with genomic data; and 1 study (6.2%) combining histologic imaging with clinical data. Studies that compared multimodal models to unimodal-only models demonstrated improved predictive performance. The risk of bias was mixed, most commonly due to inconsistent methodological reporting. Overall, the use of multimodal data in DL assessments of gliomas leads to a more accurate overall survival prediction. However, due to data limitations and a lack of transparency in model and code reporting, the full extent of multimodal DL as a resource for brain tumor patients has not yet been realized
