Beyond Health Infrastructure: Capacity, Supply Chain Dependencies, and Early Warning Signals of Health System Collapse

Abstract

Health system infrastructure is commonly assessed through healthcare facilities, equipment, and physical resources; however, the continuity of essential services also depends on operational capacity, supply chains, and critical systems beyond the health sector. This study aimed to identify infrastructure-, capacity-, and supply-related vulnerabilities and develop an early warning framework for detecting deterioration before health system functional failure or collapse.

This is a qualitative exploratory study was conducted using semi-structured interviews with 15 experts in health policy and management, health systems research, infrastructure, logistics, and supply chain management. Thematic analysis was used to identify dimensions, dependencies, failure pathways, and measurable warning signals. Findings were subsequently mapped to the Stability–Efficiency–Adaptability (SEA) model.

Analysis generated a five-level framework extending from national critical infrastructure and strategic systems to health-system networks, regional and distribution systems, healthcare facilities, and point-of-care availability. Infrastructure, capacity, and supply chains emerged as distinct but functionally interdependent domains. Capacity deterioration followed a progression from nominal to available, functional, accessible, and effective capacity. Supply chain vulnerability extended from raw materials and active pharmaceutical ingredients through manufacturing, procurement, importation, transportation, storage, distribution, and point-of-care availability, encompassing both medical and critical non-medical inputs. Expert-derived indicators were classified across five risk levels from Safe to Near Collapse. SEA analysis highlighted the importance of stability, resource-use efficiency, and adaptive buffers, including redundancy, reserves, alternative suppliers, routes, and surge capacity.

Early warning assessment should move beyond physical healthcare infrastructure toward monitoring functional capacity, upstream dependencies, supply continuity, redundancy, and adaptive reserve. Detecting deterioration across these interconnected domains may provide an earlier opportunity for intervention before system saturation progresses to functional failure and collapse.
