Abstract

Purpose: The present study examines how supply chain integration enhances efficiency, accessibility, and quality distribution in long-term elderly care. As global aging intensifies operational pressures on care institutions, understanding supply chain functions beyond clinical factors has become essential for sustaining reliable elderly services. Research design, data and methodology: A systematic literature review was conducted based on PRISMA guidelines. Studies from healthcare supply chain management, elder care operations, and social welfare systems published over the past 15 years were screened. Inclusion criteria focused on supply chain integration practices, digital innovations, operational performance, and applicability to long-term care. Due to heterogeneous evidence, findings were synthesized narratively rather than through meta-analysis. Results: Integrated supply chains reduce redundancy, prevent stockouts, and optimize forecasting for chronic-demand items such as medications, hygiene products, and mobility aids. Accessibility improves through coordinated procurement, shared inventories, and digital tracking systems that support timely distribution across both facility-based and home-based care settings. Quality distribution strengthens through standardized procurement, improved traceability, and heightened supply reliability, contributing more consistent care. Conclusions: Supply chain integration provides a strong operational foundation for long-term elderly care by improving efficiency, equity, and service quality. Digital tools, coordinated governance, and resilient procurement systems are central to enhancing welfare outcomes for older adults.
