The COVID-19 pandemic has resulted in discussion on how to allocate scarce medical resources such as ventilators. Some bioethicists have suggested that difficult determinations about withholding or withdrawing treatment should be made by triage officers or committees to alleviate the psychological strain on frontline clinicians. However, this raises concerns about shifting important personal medical decisions away from physicians and their patients. According to the principle of subsidiarity, frontline clinicians, together with their patients, should be making these decisions, with ethics committees or triage committees serving only in an advisory capacity. Several ethical principles can help health care professionals allocate scarce resources. These include basing exclusion criteria on clinical status rather than nonmedical characteristics; randomizing treatment for clinically similar patients; obtaining free and informed consent when considering the withdrawal of treatment, even in situations where treatment is possibly futile; and emphasizing quality palliative care for all patients.
