A Framework for Rationing Ventilators and Critical Care Beds During the COVID-19 Pandemic

As the coronavirus disease 2019 (COVID-19) pandemic intensifies, shortages of ventilators have occurred in Italy and are likely imminent in parts of the US. In ordinary clinical circumstances, all patients in need of mechanical ventilation because of potentially-reversible conditions receive it, unless they or their surrogates decline. However, there are mounting concerns in many countries that this will not be possible and that patients who otherwise would likely survive if they received ventilator support will die because no ventilator is available. In this type of public health emergency, the ethical obligation of physicians to prioritize the well-being of individual patients may be overridden by public health policies that prioritize doing the greatest good for the greatest number of patients.¹ These circumstances raise a critical question: when demand for ventilators and other intensive treatments far outstrips the supply, what criteria should guide these rationing decisions?
