Develop a comprehensive ethical framework to analyze the following dilemma: A hospital has limited ventilator resources during a pandemic and must decide which patients receive treatment. The hospital administration has requested a policy that balances medical utility with ethical considerations. Your framework should incorporate at least three different ethical theories (e.g., utilitarianism, deontology, virtue ethics) and address: 1) Prioritization criteria 2) Resource allocation principles 3) Mechanisms for transparency and accountability 4) Processes for appealing decisions 5) Considerations for healthcare worker wellbeing. Provide recommendations for implementation with justification for each element.
