Disaster/Pandemic Ethics — Resource Allocation & Triage
Also known as Disaster ethics · Pandemic triage · Resource allocation · SOFA score triage · Maximise lives saved · Fair innings · Triage committee · Crisis standards of care · Conventional contingency crisis surge · START triage · Mass casualty triage · Ventilator allocation framework · Multiprinciple allocation · Reverse triage · Duty to care · Withdrawal to reallocate
Disaster/pandemic ethics — the shift from individual focus (standard ICU) to population focus (maximise good across all) when demand exceeds supply. Mass casualty triage (START — simple triage and rapid treatment; reverse triage for burns/electrical). Surge capacity tiers: conventional → contingency → crisis, with crisis standards of care. Resource allocation principles: maximise lives saved (utilitarian), maximise life-years (fair innings), instrumental value (healthcare workers), random lottery tie-breaker. Ethical frameworks compared (utilitarian, egalitarian, prioritarian). Ventilator allocation frameworks: SOFA-based single-principle vs multiprinciple (SOFA + comorbidity + age caps + exclusions). SOFA score as the objective prognosis tool, re-triaged dynamically. Crisis standards of care must be DECLARED. Triage committee SEPARATE from the treating team. Withdrawal to reallocate: defensible only under declared crisis standards, ex ante framing, never ad hoc. Duty to care versus duty to self, set by reciprocity.

Meet the patient
Your region has formally declared crisis standards of care in a severe COVID wave. There is one ventilator left and three candidates: a 28-year-old previously well woman with COVID ARDS, SOFA 7; a 58-year-old with ischaemic cardiomyopathy and COVID ARDS, SOFA 9, on noradrenaline; and a 72-year-old retired ICU nurse with COVID ARDS, SOFA 10, failing to improve at 60 hours.[1]
The question staring at you is the one disaster ethics exists to answer: what publicly defensible, consistently applied, reviewable process decides who receives a scarce resource when not all can? You do not make this decision at the bedside — you hand it to a triage committee applying a published protocol. The rest of this topic is the protocol.[1][14]
