The ROK's national AMS pilot illustrates how government-led policy, financing, and accountability mechanisms can motivate large-scale stewardship implementation. The initiative provides a replicable model for embedding stewardship into health systems while aligning public health priorities with clinical practice. Lessons from the Korean experience are relevant for countries seeking to strengthen national AMR strategies, particularly in resource-limited settings. By institutionalizing stewardship at the policy level, the program offers critical insights for sustaining progress against AMR and advancing global health security.
