Infection Prevention Considerations for a Multi-Mission Convention Center Field Hospital in Baltimore, Maryland, During the COVID-19 Pandemic.

The state of Maryland identified its first case of coronavirus disease 2019 (COVID-19) on March 5, 2020. The Baltimore Convention Center (BCCFH) quickly became a selected location to set up a 250-bed inpatient field hospital and alternate care site. In contrast to other field hospitals throughout the United States, the BCCFH remained open throughout the pandemic and took on additional COVID-19 missions, including community severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) diagnostic testing, monoclonal antibody infusions for COVID-19 outpatients, and community COVID-19 vaccinations.To prevent the spread of pathogens during operations, infection prevention and control guidelines were essential to ensure the safety of staff and patients. Through multi-agency collaboration, use of infection prevention best practices, and answering what we describe as PPE-ESP, an operational framework was established to reduce infection risks for those providing or receiving care at the BCCFH during the COVID-19 pandemic.
