Lessons From COVID-19 for the Next War: Crisis Standards of Care in the Role 3 Intensive Care Unit

The rationing of medical resources became a common practice during the SARS-CoV-2 (COVID-19) pandemic. To cope with overwhelming patient numbers, hospitals were forced to adopt "crisis standards of care" (CSC) guidelines, which allow physicians to navigate the task of rationing health care resources in both an effective and ethically sound manner. The Military Health System currently has clinical guidelines for mass casualty incident (MCI) triage but lacks deployed Role 3 intensive care unit (ICU) CSC guidelines. In future peer and near-peer conflicts, this gap may prove detrimental when thousands of casualties following a single battle create a continuous and prolonged mass casualty event. The challenges of providing critical care in a battlefield hospital during a large conflict are unique and numerous, but lessons from COVID-19 ICUs such as transitioning to a utilitarian ethic, clear definitions, decision points, and decision authorities, as well as the establishment of clinical practice guidelines formulated from evidence-based protocols, can better prepare the U.S. expeditionary medical force for future conflicts. A battlefield CSC will allow military critical care physicians and nurses to manage overwhelmed ICUs and make better triage decisions, allowing them to provide a higher quality of care to the collective. In this commentary, we explore the need for Wartime CSC in the battlefield Role 3 ICU and the tools and methods used by civilian and military institutions to create and enact CSCs throughout the COVID-19 pandemic.
