Designing Reliable Care Through Clinical Pathways: A Human Factors Framework.

Background/Objectives: Healthcare delivery systems are inherently complex, and efforts to improve quality and safety often fail to achieve sustained, system-wide impact because of misalignment between work system design, care processes, and clinical practice. This article presents a practical, theory-informed framework that integrates human factors and systems thinking to guide the design and implementation of clinical pathways for reliable care delivery and system-level transformation. Methods: A conceptual framework was developed through synthesis of literature from human factors engineering, sociotechnical systems theory, and healthcare quality improvement. The framework organizes healthcare delivery into three interconnected domains-the work system, care processes, and outcomes-while positioning clinical pathways as the operational mechanism linking system design to care execution. Pediatric immunization was used as an illustrative case example. Results: The framework illustrates how misalignment in system design may contribute to variability in care processes and outcomes. Clinical pathways integrated into routine workflows and supported by human factors strategies-including decision-support heuristics, workflow simulation, and structured debriefing-may promote more reliable care delivery. Sustained implementation across teams and clinical settings is expected to reduce missed opportunities, improve consistency of care, and support progression toward system-level transformation. Conclusions: Clinical pathways can serve as practical tools for translating system design principles into reliable healthcare delivery when implemented using human factors and systems-based approaches. This framework provides healthcare leaders and quality improvement teams with a structured approach for designing, implementing, and scaling pathways to support safer, more reliable, and more consistent care delivery.
