Medication dosing errors in pediatric care remain a persistent threat despite widespread adoption of electronic health record systems and clinical decision support tools. Current AI-enabled pipelines excel at pattern recognition but lack formal mechanisms to embed dynamic contextual constraints—patient-specific physiological state, temporal pharmacokinetics, institutional protocols, and workflow interruptions—directly into the decision lifecycle. This conceptual manuscript introduces the pediatric contextual constraint error-prevention framework (PCCEPF). This theoretical architectural model treats error prevention as an orchestrated, closed-loop constraint-design process rather than a post-hoc alert layer. Drawing exclusively on peer-reviewed literature in clinical AI architectures, EHR intelligence ecosystems, healthcare analytics infrastructures, and governance systems, the PCCEPF proposes a four-layer infrastructure with a unique bidirectional drift-aware feedback topology. The model formalizes risk propagation, decision confidence, and governance load through interpretive equations that remain agnostic to any empirical dataset or training regime. By shifting from reactive alerting to proactive contextual constraint orchestration, the framework addresses critical gaps in pediatric safety: age-dependent dosing variability, rapid physiological drift, and interoperability-induced context loss. Theoretically, PCCEPF offers a blueprint for next-generation AI governance that integrates seamlessly with existing decision support pipelines while enforcing continuous monitoring and adaptive constraint refinement. This architectural approach promises to reduce preventable dosing harm in neonatal and pediatric intensive care without requiring new data collection or model retraining. The manuscript delineates the full lifecycle, layer specifications, feedback topology, and formal interpretive models, providing a ready-to-adapt infrastructure for health-system deployment.
