Abstract
En 中文
Intensive care units (ICUs) are designed to support critically ill patients through life-threatening organ dysfunction, relying on highly optimized processes and specialized resources. Yet they are increasingly exposed to systemic shocks of geopolitical, environmental, and technological origin. These act not only on infrastructure and workforce but, more insidiously, through the supply chains on which bedside care depends, rendering ICU autonomy largely illusory: the production of active pharmaceutical ingredients is highly concentrated geographically, while some critical products depend on a single manufacturing site worldwide; consequently, a disruption at a single node can propagate rapidly to the bedside. We trace this cascade, from shock to the depletion of just-in-time buffers and the distorting effect of phantom demand, to the rationing, substitution, and improvisation that increase workload, variability, and clinical risk. This fragility is not incidental but the product of decades of efficiency-driven reform that has systematically reduced organizational slack: the inventory, redundant capacity, and workforce flexibility that enable adaptation under stress. The relationship between efficiency and resilience should be understood as a structural tension rather than a fixed trade-off. Targeted organisational strategies can strengthen ICU resilience, including regionalized ICU networks governed by formal agreements, diversification and strategic stockpiling of high-risk medications, and pre-emptive protocols for drug and fluid conservation. Scalable digital infrastructure and in-situ simulation can further support these strategies. Resilience should therefore be understood as a design principle, not an emergent property of crisis response.
