The U.S. health care system should learn many lessons from the Covid-19 pandemic. A key one is that it’s time to unleash the power of the country’s nursing workforce. Nurses have been essential in combating Covid-19, from their work caring for patients hospitalized with severe Covid-19 to treating people in their homes and administering vaccines. But even without a pandemic, it’s clear that when nurses are free to fully deploy their expertise and training, they not only improve health care quality and access but can also help dismantle systemic inequities tied to geography, racism, and poverty that affect people’s health.
