Purpose: To explore pediatric oncology referral practices, gather healthcare providers’ perspectives of barriers to access and provision of rehabilitation service across Canada, and inform a framework for action to optimize rehabilitation care and inform future research. Methods: A cross-sectional survey was conducted with Canadian healthcare professionals (HCPs) working in pediatric oncology. Results: A total of 54 responses were received, and 34 corresponded to HCPs who refer children with cancer to rehabilitation services. Results suggest that approximately 25% of children are referred to rehabilitation services, primarily when the child presents with, or is at risk of, significant functional disability due to surgery. A primary barrier to service provision identified across HCPs included a lack of funding and resources. Medical professionals further identified a lack of specialized pediatric oncology rehabilitation services, whereas rehabilitation professionals identified the lack of pediatric oncology specific space and equipment. Identified themes from open-ended survey questions include the need for (1) dedicated funding and resources, (2) improved access, and (3) the need for specialized pediatric oncology rehabilitation services. Conclusion: Several barriers exist in the Canadian healthcare context that impact the delivery of rehabilitation services for children with cancer. We propose a framework for action to advance clinical care and guide future research.
