Introduction: In children and adolescents, brain and central nervous system (CNS) tumors are the leading types of cancers. Past studies have found differing rates of intracranial cancers among races and identified additional cancer risk factors. This study aimed to see if these differences can be substantiated with further investigation of the latest version (2019) of the Kids’ Inpatient Database (KID). Methods: A total of 7,818 pediatric patients 21 years old in KID with ICD-10 codes consisting of malignant neoplasms of the brain, brainstem, and cerebral meninges (C700, C709–C719) were queried. Modifiable risk factors evaluated include: hospital region, insurance type, hospital city size, the average income of patient zip code, and location/teaching status of a hospital. Non-modifiable risk factors were race and sex at birth. Dependent variables were tested in Excel and GraphPad Prism 9 using a χ2 test with Yates’ continuity correction and Tukey’s one-way and two-way ANOVAs. Results: Mortality rates of females (2.88%) compared to males (1.99%) were significant (p 0.05). Mortality was (4.17%) in black patients compared to (1.68%) for white (p 0.0001), Hispanic mortality (2.95%) compared to white (p 0.01), and mortality of Asian/Pacific Islander (3.86%) compared to white (p 0.01). Black patients had significantly higher mortality than white, Hispanic, Asian/Pacific Islander, Native American, and other races overall (p 0.01). There was no significant difference in the mortality rates between children’s hospitals and large hospitals for any race. After accounting for patient race, mortality was still not significantly different for patients with Medicaid insurance compared to non-Medicaid insurance types. Of the children treated at children’s hospitals, the most transferred in from outside hospitals were Native American (20.00%) followed by Asian/Pacific Islander (15.09%) then Hispanic patients (13.67%). A significant difference between races was also seen regarding length of stay (p 0.001) and number of charges (p 0.001). Conclusion: These findings confirm prior studies suggesting gender and race are significant factors in mortality rates for children with intracranial neoplasms. However, the findings do not identify the root causes of these discrepancies but may serve as an impetus for clinicians, healthcare administrators, and governmental leaders to improve national resource allocation to better care for pediatric patients with intracranial neoplasms.
