Introduction: Children with developmental disabilities frequently require long-term, multidisciplinary, and family-centered healthcare services. However, caregivers often encounter structural, logistical, communication, and professional barriers when accessing healthcare services for their children. Understanding both barriers and facilitators from caregiver and healthcare provider perspectives is essential for improving inclusive healthcare.Objective: This study aimed to explore barriers and facilitators to inclusive healthcare for children with developmental disabilities from the perspectives of caregivers and healthcare providers.Methods: A qualitative descriptive study was conducted using individual semi-structured interviews with 36 participants, consisting of 20 caregivers and 16 healthcare providers. Participants were recruited purposively from hospitals, rehabilitation centers, and community health facilities. Interviews were conducted individually, audio-recorded, transcribed verbatim, and analyzed using inductive thematic analysis. Recruitment continued until thematic saturation was achieved, defined as the point at which no new codes, categories, or themes emerged across consecutive interviews.Results: Six themes were identified: structural constraints within healthcare systems, accessibility and logistical barriers, communication dynamics between caregivers and healthcare providers, professional competency and training gaps, caregiver resilience and advocacy, and collaborative community-based support systems. Key barriers included limited specialized services, long waiting times, transportation difficulties, complex referral pathways, and insufficient provider training. Facilitators included caregiver advocacy, interdisciplinary collaboration, peer support networks, and community-based support systems.Conclusion: Inclusive healthcare for children with developmental disabilities requires system-level improvements in healthcare infrastructure, referral coordination, provider training, family-centered communication, and community-based support. Strengthening these areas may improve equitable healthcare access, particularly in resource-constrained settings
