The challenges of low and middle-income countries in healthcare management after COVID-19

More than two years after WHO declared the novel coronavirus (COVID-19) outbreak a pandemic, a year after deploying the first COVID vaccine, and as we approach nearly 6.5 million infection-related deaths1, we wonder, as Brazilian front-line physicians, what are the lessons we should have learned. Accordingly, healthcare was the first of all systems affected by COVID-19, particularly in developing nations. Despite the additional costs of unemployment, supply chain disturbances, finance expenses to support businesses, and millions of children deprived of education, we still witness the abundance of daily clinical practices of low-value care, failed public health policies, and scientific researches of controversial relevance and not centered in the patient.
