Pediatric Neurosurgical Capacity for the Care of Children With CNS Tumors Worldwide: A Cross-Sectional Assessment

Abstract

PURPOSEEfforts to address inequities in the treatment of pediatric CNS tumors and the burden of childhood cancer globally have prompted the designation of low-grade glioma as one of six index cancers for the World Health Organization Global Initiative for Childhood Cancer. Understanding the importance of neurosurgical interventions and evaluating pediatric neurosurgical capacity may identify critical interventions to improve outcomes for children with low-grade glioma and other CNS tumors.METHODSAn online, cross-sectional survey assessing pediatric neurosurgical practice and capacity was distributed to members of the International Society of Pediatric Neurosurgery. The survey included 36 items covering domains including patient volume, available infrastructure, scope of practice, case distribution, and multidisciplinary care.RESULTSResponses from 196 individuals from 61 countries, spanning all WHO regions, were included. Ninety-six (49.0%) were from high-income countries, 57 (29.1%) were from upper-middle–income countries, 42 (21.4%) were from lower-middle–income countries (LMICs), and 1 was (0.5%) from a low-income country. Most respondents had a catchment population of ≥ 1 million and indicated the availability of basic neurosurgical resources such as a dedicated neurosurgical operating theater and surgical microscope. The presence of a neurosurgical intensive care unit, inpatient rehabilitation services, and infection monitoring showed similar availability across country groups. Quantitative scoring of 13 infrastructure and service items established that fewer resources were available in low-income countries/LMICs and upper-middle–income countries compared with high-income countries. The volume of pediatric CNS tumor cases and case distribution did not vary according to World Bank country groups.CONCLUSIONThis study provides a comprehensive evaluation of pediatric neurosurgical capacity across the globe, establishing variability of resources on the basis of the country income level. Our findings suggest that pediatric neurosurgeons in LMICs may benefit from key neurosurgical instrumentation and increased support for multidisciplinary brain tumor programs and childhood cancer research efforts.
