Question: Has the CDC provided special guidance for surgical arenas in light of the COVID-19 pandemic?

Answer passage (source: CDC):
page_title: Healthcare Infection Prevention and Control FAQs for COVID-19
section_headers: During the COVID-19 pandemic, are there special considerations for surgical and other procedural care settings, including performance of aerosol-generating procedures (AGPs)?
section_content: As part of routine practices, healthcare personnel (HCP) should be applying
Standard Precautions. HCP
should always deliberately assess potential risks of exposure to infectious
material before engaging in activities and procedures in healthcare delivery.
Based on their risk assessment, safe work practices, including engineering
controls that reduce the release of infectious material, administrative
controls, and use of personal protective equipment (PPE) should be implemented
at the point of care according to CDC guidelines and standards of practice for
the activity performed.
To reduce SARS-CoV-2 exposure during the COVID-19 pandemic, CDC recommends
that facilities:

consider nonoperative approaches when feasible;
minimize the use of procedures or techniques that might produce infectious aerosols when feasible;
minimize the number of people in the operating or procedure room to reduce exposures;
use the extent of community transmission and an assessment of the likelihood for patient harm if care is delayed to make decisions about cancelling or postponing elective surgeries and procedures; and
implement universal source control measures, which includes having patients wear a cloth face covering (as tolerated) and having HCP wear a facemask at all times while they are in the healthcare facility.

If surgery or procedures cannot be postponed, HCP caring for patients with
suspected or confirmed COVID-19 should adhere to all recommended infection
prevention and control practices for
COVID-19.
This includes:

Using all recommended PPE: an N95 or higher-level respirator (or facemask if respirators are not available), eye protection, gloves, and a gown. 
Respirators with exhalation valves should not be used during surgical procedures as unfiltered exhaled breath would compromise the sterile field.
If shortages exist, N95 or higher-level respirators should be prioritized for procedures involving higher risk techniques (e.g., that generate potentially infectious aerosols) or that involve anatomic regions where viral loads might be higher (e.g., nose and throat, oropharynx, respiratory tract).


As part of routine practice, HCP should also be using additional engineering controls for source control, when applicable (e.g., smoke evacuation devices).

Because COVID-19 can be transmitted asymptomatically, some infected
individuals will not be identified based on clinical signs and symptoms. HCP
providing surgical or procedural care to patients not suspected of having
COVID-19 should use a tiered approach based on the level of community
transmission to inform the need for universal eye protection and respirator
use (see FAQ addressing recommended PPE when caring for asymptomatic patients
who are not suspected to have COVID-19). HCP should continue to use eye
protection or an N95 or higher-level respirator whenever recommended for
patient care as a part of Standard or Transmission-Based Precautions.

Reviewer feedback on this answer:
Although answer is acceptable, it could have went into more detail on the exact topic of surgical arenas.
This is a good answer. It refers to PPE that HCPs should be using. It talks about some of the procedures and protocols to follow which should answer the question head on

page_title: Clinical Questions about COVID-19: Questions and Answers
section_headers: Testing, Diagnosis, and Notification
Should chest CT be used for diagnosis of COVID-19?
section_content: Clinicians considering use of chest CT scans for diagnosis or management of
COVID-19 patients should consider whether such imaging will change clinical
management. The American College of Radiology (ACR) recommends that CT should
not be used to screen for COVID-19, or as a first-line test to diagnose
COVID-19, and that CT should be used sparingly and reserved for hospitalized,
symptomatic patients with specific clinical indications for CT. Appropriate
infection control procedures should be followed before scanning subsequent
patients. For more information see, ACR Recommendations for the use of Chest
Radiography and Computed Tomography (CT) for Suspected COVID-19

Reviewer feedback on this answer:
The answer is not on topic about surgical arenas.
This seems like a pretty good answer. It's very specific answering about CT scans so they could probably widen the scope of the answer to make it better for the way the question was asked.

page_title: Healthcare Infection Prevention and Control FAQs for COVID-19
section_headers: Do CDC’s interim infection prevention and control recommendations for COVID-19 apply to psychiatric hospitals or other behavioral health facilities?
section_content: Yes. To keep patients and healthcare personnel (HCP) healthy and safe, CDC’s
infection prevention and control guidance applies to all settings where
healthcare is delivered. However, as with any guidance, facilities can tailor
certain recommendations to their setting. For example, inpatient psychiatric
care includes communal experiences and group activities that may need to
continue. If so, these activities might need to be adapted to align with
social distancing recommendations. Other recommended infection control measures
(for example, ensuring access to alcohol-based hand sanitizer, cohorting
patients with COVID-19 and assigning dedicated staff, or implementing
universal source control measures) might not be safe or appropriate to
implement in all locations or for all patients due to security and behavioral
concerns.
Challenges and potential solutions specific to behavioral health settings
might include:

Cohorting 
Challenge: To prevent transmission, it is generally recommended that patients with COVID-19 be transferred to a separate area of the facility where they can be cared for by dedicated HCP. Because of security concerns or specialized care needs, it might not be possible to cohort certain patients together or change HCP assigned to their care.
Potential Solutions: When cohorting is not possible, implement measures to maintain social distancing (at least 6 feet) between patients with COVID-19 and others on the unit. Ideally, this would include a separate bathroom for COVID-19 patients. Ensure HCP wear all recommended personal protective equipment (PPE) when caring for patients with suspected or confirmed COVID-19.


Group Therapy Sessions 
Challenge : Group counseling, therapy, and discussion sessions are a critical component of psychiatric treatment and care plans, but the traditional set-up for these activities is not compatible with social distancing recommendations.
Potential Solutions : When possible, use virtual methods, or decrease group size so social distancing can be maintained. In the event that COVID-19 is transmitted in the facility, sessions should stop or move to a video discussion forum until additional infection prevention measures are in place to stop the spread.


Cloth Face Coverings 
Challenge: For some patients, the use of cloth face coverings or facemasks might pose an additional danger or may cause distress. Some patients may be unable or unwilling to use them as intended. Elastic and cloth straps can be used for strangling oneself or others, and metal nasal bridges can be used for self-harm or as a weapon.
Potential Solutions: Consider allowing patients at low risk for misuse to wear cloth face coverings or facemasks, with a preference for those with short ear-loops rather than longer ties. Consider use of cloth face coverings or facemasks during supervised group activities. Ensure that HCP interacting with patients who cannot wear a cloth face covering or facemask are wearing eye protection and a facemask (or a respirator if the patient is suspected to have COVID-19 and respirators are available).


Alcohol-based Hand Sanitizer 
Challenge : While alcohol-based hand sanitizer (ABHS) containing 60-95% alcohol is an important tool to increase adherence to hand hygiene recommendations, ABHS must be used carefully in psychiatric facilities to ensure it is not ingested by patients.
Potential Solutions : Consider not placing ABHS in patients’ rooms in psychiatric facilities, nor in locations where the patients have unsupervised access. Encourage frequent hand washing with soap and water for patients and HCP. Consider providing personal, pocket-sized ABHS dispensers for HCP.


Dining 
Challenge : As part of social distancing, communal dining is generally not recommended. However, eating needs to remain supervised due to the potential for self-harm with eating utensils and because commonly used psychiatric medications may cause side effects (e.g., tardive dyskinesia, dysphagia, hypo- and hypersalivation) that increase choking risk for patients.
Potential Solutions : One option is to position staff in patients’ rooms to monitor their dining. Another option is to allow communal dining in shifts so that staff can monitor patients while ensuring they remain at least 6 feet apart. A third option is to have patients sit in appropriately spaced chairs in the hallway outside their rooms so they can be monitored while they eat.


Smoking 
Challenge: A higher proportion of psychiatric patients smoke cigarettes compared to the general population. Patients might congregate in outdoor smoking spaces without practicing appropriate social distancing.
Potential Solutions: Limit the number of patients allowed to access smoking spacesat the same time, and position staff to observe and ensure patients are practicing appropriate physical distancing.
