COVID-19: What we’ve done well and what we could or should have done better—the 4 Ps

As a result, systems and staff were placed under immense pressure as everyone tried to optimize patient management. As the pandemic continues, we must apply what we have learned about our response, both good and bad, to improve organization and thus patient care in the future.
