Influence of socioeconomic status on clinical outcomes of diffuse midline glioma and diffuse intrinsic pontine glioma.

OBJECTIVE: Given the lack of a definitive treatment and the poor prognosis of patients with diffuse midline glioma (DMG) and diffuse intrinsic pontine glioma (DIPG), socioeconomic status (SES) may affect treatment access and therefore survival. Therefore, this study aimed to examine the relationship between SES and treatment modalities, progression-free survival (PFS), and overall survival (OS) in children with DMG/DIPG. METHODS: A retrospective, single-institution review was conducted of medical records of patients ≤ 18 years of age who had DMG or DIPG that was diagnosed between 2000 and 2022. Patient demographics, surgical interventions, chemotherapy, radiation therapy, clinical trial enrollment, and medical care-related travel were extracted. SES variables (education and mean income) for associated patient census tracts were collected and stratified. Statistical analysis using unpaired t-tests, chi-square analysis, and log-rank tests was conducted. RESULTS: Of the 96 patients who met the inclusion criteria, the majority were female (59%) and non-Hispanic White (57%). The median PFS, median OS, and time from diagnosis to treatment did not differ between races/ethnicities or sex. Ninety-one of 96 patients had census tract data available. Patients from higher-income census tracts (> 50% of families with annual household income greater than $50,000) had a longer median OS (480 vs 235 days, p < 0.001) and traveled significantly longer distances for medical care (1550 vs 1114 miles, p = 0.048) than families from lower-income census tracts. Patients from the highest education quartile traveled significantly farther for treatment than the lowest education quartile (mean 2964 vs 478 miles, p = 0.047). Patients who received both oral and intravenous chemotherapy were more likely to be from higher-income census tracts than those who received intravenous or no chemotherapy. Duration of PFS, rates of clinical trial enrollment, biopsy rates, H3K27 mutation status, ventriculoperitoneal shunt placement rates, and radiotherapy rates were not associated with SES variables. CONCLUSIONS: Patients from families from higher-income census tracts experienced longer OS and traveled farther for treatment. Patients from families from higher-education-level census tracts traveled more often for treatment. The authors' findings suggest that SES influences DMG and DIPG OS. More studies should be done to understand the role of SES in the outcomes of children with DMG/DIPG.

Language-discordant care in pediatric neurosurgery: parent and provider perspectives on challenges and multilevel solutions to reduce disparities.

OBJECTIVE: In the United States, Spanish is the second most spoken language, with nearly 42 million individuals speaking Spanish at home. Spanish speakers have been noted to have higher rates of unfavorable neurosurgical outcomes; however, to the authors' knowledge, no study has explored the experiences of patients, caregivers, and providers receiving or delivering neurosurgical care in language-discordant settings. In this study, the authors sought to identify challenges faced by pediatric neurosurgery providers and Spanish-speaking parents communicating with a language barrier and propose solutions to address those challenges. METHODS: Spanish-speaking parents and pediatric neurosurgery providers were invited to participate in semistructured interviews. Purposeful sampling was used to recruit Spanish-speaking parents whose child had recently undergone neurological surgery at the authors' institution and to identify pediatric neurosurgery clinical team members to interview, including physicians, advanced practice providers, and interpreters. Codes were inductively developed and applied to transcripts by two researchers. Thematic analysis was conducted to identify challenges faced by parents and providers. RESULTS: Twenty individuals were interviewed, including parents (n = 8), advanced practice providers (n = 5), physicians (n = 3), interpreters (n = 2), a social worker (n = 1), and a nurse (n = 1). Three challenges were identified. 1) Compared with English-speaking parents, providers noted that Spanish-speaking parents were less likely to ask questions or raise new concerns. Concurrently, Spanish-speaking parents expressed a desire to better understand their child's future medical needs, care, and development. 2) There is a dearth of high-quality resources available in the Spanish language to supplement patient and parent neurosurgical education. 3) Both parents and providers invariably prefer in-person interpreters; however, their availability is limited. CONCLUSIONS: Three challenges were identified by Spanish-speaking parents of pediatric neurosurgery patients and providers when receiving or delivering care through a language barrier. The authors discuss multilevel solutions that, if deployed, could directly address these shared challenges. Furthermore, optimizing communication may help mitigate the disparities experienced by non-English-speaking Hispanic/Latino individuals when receiving neurosurgical care.

Screening and surgery for foramen magnum stenosis in children with achondroplasia: a large, national database analysis.

OBJECTIVE The goal of this study was to determine the rates of screening and surgery for foramen magnum stenosis in children with achondroplasia in a large, privately insured healthcare network. METHODS Rates of screening and surgery for foramen magnum stenosis in children with achondroplasia were determined using de-identified insurance claims data from a large, privately insured healthcare network of over 58 million beneficiaries across the United States between 2001 and 2014. Cases of achondroplasia and screening and surgery claims were identified using a combination of International Classification of Diseases diagnosis codes and Current Procedural Terminology codes. American Academy of Pediatrics (AAP) practice guidelines were used to determine screening trends. RESULTS The search yielded 3577 children age 19 years or younger with achondroplasia. Of them, 236 met criteria for inclusion in the screening analysis. Among the screening cohort, 41.9% received some form of screening for foramen magnum stenosis, whereas 13.9% of patients were fully and appropriately screened according to the 2005 guidelines from the AAP. The screening rate significantly increased after the issuance of the AAP guidelines. Among all children in the cohort, 25 underwent cervicomedullary decompression for foramen magnum stenosis. The incidence rate of undergoing cervicomedullary decompression was highest in infancy (28 per 1000 patient-years) and decreased with age (5 per 1000 patient-years for all other ages combined). CONCLUSIONS Children with achondroplasia continue to be underscreened for foramen magnum stenosis, although screening rates have improved since the release of the 2005 AAP surveillance guidelines. The incidence of surgery was highest in infants and decreased with age.
