COVID-19 and Hospital and Facility Administration

1. Does the ASA have any kind of algorithm or decision tree on how to handle patients coming through for elective, urgent and emergent surgery during COVID-19 spikes?

• ASA joined with the American Hospital Association (AHA), Association of periOperative Registered Nurses (AORN), and the American College of Surgeons (ACS) on guidance related to case prioritization for local facilities should handle elective, urgent and emergent surgery. That guidance can be found in our Roadmap for Maintaining Essential Surgery during COVID-19 Pandemic document. There are many contingencies that a hospital must consider, including, but not limited to, patient population, community COVID-19 spread, social distancing, equipment availability and type of elective procedure. Hospitals, anesthesiology departments and other healthcare workers should work together to create their own institutional algorithm or decision tree based on these factors.

2. Why are anesthesiologists being asked to perform more intubations in my facility when there are other physicians who are trained to do so?

• In each location where intubations take place, the most experienced professional for that location should perform the intubation. In the operating room, this should be the most experienced anesthesia professional available. In non-operating room locations, including the Emergency Room and ICU, this should be an emergency medicine, critical care medicine or anesthesia professional, depending on availability and staffing for the facility. Every facility should develop a protocol for which medical service responds to the need for non-OR intubations. This is not a training opportunity for students. Anesthesiologists would expect to be consulted when there are difficult intubations or to assist with a surge of patients. Anesthesiology departments should work with hospital administrators and other personnel who are trained in intubation (e.g. critical care and emergency departments) on clear guidance that protects healthcare worker and patient safety. Stakeholders should conduct debriefings to discuss how to improve the process.

3. Does ASA have any recommendations on using negative pressure rooms when intubating or delivering surgical care to COVID-19 patients?

• ASA recommendations state, “When possible, perform procedures in an airborne infection isolation room rather than in an operating room. An airborne isolation room has a negative-pressure relative to the surrounding area. In contrast, a typical operating room is designed to provide positive-pressure relative to the surrounding area and incoming air is often flow-directed, filtered, and temperature and humidity controlled. If a procedure cannot be postponed or done at the bedside, then schedule the patient when a minimum number of healthcare workers and other patients are present in the surgical suite.”
• We recognize that limited resources and available rooms in a specific hospital may decrease the opportunity for this to occur. In those instances, considerations should include possibility of a difficult airway (benefit/risk operating room vs ICU intubation), local resources and urgency of the situation.
• Preferably, surgical interventions should be conducted in a negative pressure room with a minimum of 12 air changes per hour (most operating rooms have 15-20 air exchanges per hour). Air is filtered with a HEPA filter and evacuated from these rooms to the external atmosphere. If a negative pressure operating room is unavailable, contact your bioengineering department for other means to optimize existing operating room ventilation (e.g., disable positive pressure flow, maximize the number of air exchanges per hour, use portable HEPA filtration system).
• We encourage anesthesiologists to also contact and collaborate with local infection control expertise on appropriate locations, planning and policy development.

4. Should we use negative pressure rooms for intubations and extubations in asymptomatic patients coming to an operating room?

• As with other considerations of asymptomatic patients, a risk assessment should take place to determine feasibility and assess safety considerations, including risk of transporting an intubated patient and the provision of bridging sedation. Next, an assessment of disease prevalence should be made. In locations with low prevalence (<1%), the risk of intubating and extubating an asymptomatic patient is most likely low. Currently there is no requirement or guidance that intubation and extubation of non-COVID19 patients should take place in a negative pressure environment. Nevertheless, planning is needed to minimize aerosolization of secretions in all patients (e.g., avoid coughing, temporary use of a transparent plastic cover during extubation), and wear appropriate PPE.

5. How long should surgical personnel wait to enter the room after a COVID-19 patient has been intubated?

• For physicians and other healthcare workers, the time to enter the room after an intubation will likely be based upon the type of PPE they are wearing and the air exchange rate of the room. A table from the CDC shows the rate that airborne contaminants are removed with various air changes per hour (ACH). Please make sure to review the table to identify the room sizes and air exchange rates in your specific facility. Such information will help to guide your policy addressing when sufficient time has elapsed to clear the air of viral particles. The CDC table indicates the time required to reach 99% and 99.9% reduction in aerosolized particles. The “safe” threshold for re-entering the room wearing a surgical mask after intubation or extubation is not known. It is a local judgement to decide what threshold is considered safe.
• For example, in the referenced CDC table, if your operating room has a typical 15 air changes per hour (ACH), one can see that 99% of the airborne pathogens will be removed from an operating room in 18 minutes and 99.9% in 28 minutes. In that scenario, unnecessary staff who leave the operating room before the time of intubation could reenter wearing a surgical mask in 18-28 minutes to participate in a non-aerosol generating surgical procedure depending upon the “safe” threshold decision. Staff wearing N95 masks and other PPE for aerosol generating procedures identified in the ASA recommendations linked above can remain in the room during the aerosol generating procedures, including intubation and extubation.

6. For a patient who has tested negative for COVID-19, should we adhere to the Air Exchange Rate calculation for healthcare workers entering the operating room who are not wearing an N95 or other PPE?

• Because false-negatives may occur with testing, droplet precautions (surgical mask and eye covering) should be used by operating room staff for operative cases. Before performing an aerosol -generating procedure, health care providers within the room should wear an N95 mask, eye protection, gloves and a gown. 
• For physicians and other healthcare workers, the time to enter the room after an intubation will likely be based upon the type of PPE they are wearing and the air exchange rate (ACH) of the room. A table from the CDC shows the rate that airborne contaminants are removed with various ACH. Please make sure to review the table to identify the room sizes and air exchange rates for your specific operating as well as procedural facility locations. Such information will help to guide your policy addressing when sufficient time has elapsed to clear the air of viral particles . The CDC table indicates the time required to reach 99% and 99.9% reduction in aerosolized particles. The “safe” threshold for re-entering the room wearing a surgical mask after intubation or extubation is not known. It is a local judgement to decide what threshold is considered safe.
• For example, in the referenced CDC table, if your operating room has a typical 15 air changes per hour (ACH), one can see that 99% of the airborne pathogens will be removed from an operating room in 18 minutes and 99.9% in 28 minutes. In that scenario, unnecessary staff who leave the operating room before the time of intubation could reenter wearing a surgical mask in 18-28 minutes to participate in a non-aerosol generating surgical procedure depending upon the “safe” threshold decision. Staff wearing N95 masks and other PPE for aerosol generating procedures identified in the ASA recommendations linked above can remain in the room during the aerosol generating procedures, including intubation and extubation. 

7. How should the operating room be decontaminated following surgery on a COVID-19 patient?

• We do not have specific guidance on how to decontaminate the operating room after a procedure with a COVID-19 patient. The current CDC guidance states that routine cleaning and disinfection procedures using an EPA-registered, hospital-grade disinfectant from List N, are appropriate for SARS-CoV-2 in healthcare settings. Upon patient leaving the room, entry should be delayed until sufficient time has elapsed for enough air changes to remove aerosolized infectious particles. The AORN Guideline for Environmental Cleaning outlines recommended cleaning procedures that should be monitored for quality and consistency. Linen and medical waste should follow the routine established practices as outlined by local, state and federal regulations.
• Please contact your local infection disease and environmental management personnel for information.

8. How do we move patients to PACU? For social-distancing purposes, do we keep an empty PACU space between recovering patients?

• Each facility must assess how it is able to maintain adequate space between patients. Extubated patients who are not suspected or known to have COVID-19 should be brought to the PACU with a face mask in place, and should be spaced at a distance of 6 feet apart. Patients that are coughing or sneezing repeatedly due to airway irritation may require an enclosed room (such as a negative pressure isolation room, if available) with limited personnel who practice full airborne precautions with eye protection (e.g., N95 masks, gowns, gloves, and eye shields).
