Creating an Intensive Care Unit From a Postanesthesia Care Unit for the COVID-19 Surge at the Veterans Affairs Ann Arbor Healthcare System

Author and Disclosure Information

Objectives: To prepare for the predicted surge of patients with COVID-19 in Southeast Michigan, the US Department of Veterans Affairs Ann Arbor Healthcare System engineered, built, and staffed a 12-bed intensive care unit (ICU) from the existing postanesthesia care unit (PACU).

Observations: Considerations including floor planning, reversal of airflow, strict airborne precautions, sealing off a dedicated nursing station, and developing an infection control plan in an open care unit. A staffing model was created that included anesthesiologist intensivists, advanced practice providers, residents, certified registered nurse anesthetists, and perioperative nurses working alongside ICU trained nurses. Challenges arose in infection control, communication, mechanical ventilation using anesthesia machines, providing renal replacement therapy, and maintaining patient privacy in an open unit.

Conclusions: This article describes the setup, challenges, and solutions that allowed the creation of the PACU-ICU to help serve veterans and civilians during a time of unprecedented strain on the health care system due to COVID-19.

The rise in prevalence of the community spread of coronavirus disease 2019 (COVID-19) in the US in early March 2020 led to hospital systems across the country preparing for an increase in critically ill patients.1 The US Department of Veterans Affairs (VA) Ann Arbor Healthcare System (VAAAHS) anticipated an increased census of veterans who would need hospital admission for severe COVID-19 as well as the potential need to receive patients from community hospitals in Southeast Michigan, the location of one of the worst outbreaks in the US at that time.2

Through the facility’s incident command center, a hospital operations group identified the postanesthesia care unit (PACU) as a space to convert to an intensive care unit (ICU) for patients with COVID-19 needing mechanical ventilation. Other hospitals throughout the world have created similar makeshift ICUs to help care for the surge of patients with COVID-19, recognizing the high level of monitoring and resources available in the perioperative setting.3-5 These ICUs have been successfully created in operating rooms,3 recovery rooms,5 and procedural settings.4

Between March 27, 2020 and April 25, 2020, a great multidisciplinary effort enabled the VAAAHS PACU-ICU to care for critically ill veterans with COVID-19 from Southeast Michigan as well as civilian transfers from overwhelmed neighboring community hospitals. This article will discuss planning considerations, including facility preparation, equipment, and staffing models. The unique challenges faced in managing an open-plan surge-capacity ICU also will be discussed as well as the solutions that were enacted.
