Resource allocation in public health ethics grapples with distributing limited resources among competing needs. It involves balancing efficiency, equity, and ethical principles to maximize health benefits while addressing disparities and promoting social justice. Key concepts include scarcity, opportunity costs, and evidence-based decision-making. Ethical frameworks like utilitarianism and egalitarianism guide choices, while stakeholders from patients to policymakers bring diverse perspectives to the table. Case studies illustrate real-world challenges in allocating resources.
