Remember the 4 Cs:

  1. Clinical indication (Principle of Benevolence and Non-maleficence)
  2. Choice of patient (Principle of respect for Autonomy)
  3. Contextual features (Principle of Loyalty and Fairness)
  4. Condition (quality) of life (Principle of Benevolence, Non-maleficence and respect for Autonomy)
  5. A 5th box can be added: Catholic perspective
four box model ethics
