David K. Warren, MD, MPH, led the Washington University School of Medicine team that made major contributions to the operations of Barnes-Jewish Hospital during the pandemic. Warren serves as the chief hospital epidemiologist for Barnes-Jewish and, starting in March 2020, he joined the incident command for the hospital. For the ensuing 18 months, he worked daily to develop and implement policies on COVID-19 testing, guidelines for protecting health-care workers and dealing with infected or exposed health-care workers, patient placement, policies for patient care in specialized inpatient and outpatient units, and resource planning. In the early part of the epidemic, this often required daily changes in policy (especially in the context of scarce resources). Warren’s service was representative of many faculty members in the Division of Infectious Diseases, who coordinated responses and developed policies across the academic medical center, the university and BJC HealthCare.
