To the Editor:
Considering the global spread of COVID-19 infection and the increased number of confirmed
COVID-19 cases across the United States, the American Association for Bronchology
and Interventional Pulmonology (AABIP) is issuing this statement on the safe and effective
use of bronchoscopy in patients with suspected or confirmed COVID-19 infection. The
main purpose of this statement is to ensure the safety of our patients, health care
team and community at large.
We are releasing these urgent recommendations to guide clinicians around the world
with the understanding that new information may subsequently modify or impact these
current recommendations. We will strive to update this statement as needed in a timely
fashion. This document is based on the latest Centers for Disease Control (CDC) recommendations
March 9, 2020 and expert consensus of the AABIP COVID-19 Task Force.
General Recommendations for collection of respiratory specimen collection for suspected
COVID-19:1–4
Collection of upper respiratory samples via nasopharyngeal and oropharyngeal swabs
is the primary and preferred method for diagnosis.
Respiratory specimen collection is recommended in suspected COVID-19 regardless of
time of onset of symptoms.
Induced sputum collection is NOT recommended.
Because it is an aerosol generating procedure that poses substantial risk to patients
and staff, bronchoscopy should have an extremely limited role in the diagnosis of
COVID-19 and only be considered in intubated patients if upper respiratory samples
are negative and other diagnosis is considered that would significantly change clinical
management.
Alternative respiratory specimen collection in the intubated patient can include tracheal
aspirates and nonbronchoscopic alveolar lavage.
If bronchoscopy is being performed for COVID-19 sample collection, a minimum of 2-3 mL
of specimen into a sterile, leak proof container for specimen collection is recommended.4
Only essential personnel should be present when performing any specimen collection.
Alert laboratory personnel regarding COVID-19 specimen processing and testing.
Additional Considerations for Respiratory Evaluation:
Constellation of fever, respiratory symptoms, and radiographic evidence of ground
glass opacities and pneumonitis should raise clinical suspicion of COVID-19.5,6 Patients
demonstrating such symptoms or findings should be queried about personal history of
recent travel to any country with a CDC level 2 or higher travel warning (currently
China, Italy, Iran, South Korea, and Japan), contact with a confirmed COVID-19 person
or contact with others with such travel history.
Clinicians should consider the local prevalence of COVID-19 cases when evaluating
the clinical risk for COVID-19 infection, understanding that a travel or exposure
history will become increasingly ineffective in identifying patients at risk for infection.
Guidelines for respiratory and contact isolation should be followed in all known or
suspected cases of COVID-19 infections.
Evaluate for influenza and respiratory syncytial virus as well as other respiratory
pathogens and additional diagnoses as clinically indicated.
For all suspected COVID-19 cases notify internal institutional infection control personnel
and state or local public health department.
General Personnel Preparation if Bronchoscopy is needed in patients with suspected
or confirmed COVID-19 infection:
Place patient in Airborne Infection Isolation Room negative pressure room isolation.
All personnel should wear a powered, Air-Purifying Respirator or N95 mask and eye
protection.
All personnel should wear standard Personal Protective Equipment which includes gown,
gloves, respiratory protection, and eye protection.
Follow CDC instructions for proper donning and doffing of all protective equipment
and disposable devices (www.cdc.gov/hai/prevent/ppe.html).
Disposable bronchoscopes should be used first line when available.
Follow standard disinfection protocol of durable reusable video monitors.
Follow standard high-level disinfection for reusable bronchoscopes.
Limit to essential medical personnel during the procedure and specimen collection.
General Precautions for performing non-urgent bronchoscopy among patients WITHOUT
suspected COVID-19 infection:
All patients presenting for previously scheduled bronchoscopy should be asked about
their recent travel history before entering the bronchoscopy suite. Bronchoscopy should
be postponed if the patient has a history of recent travel to any country with a CDC
level 2 or higher travel warning (currently China, Italy, Iran, South Korea, and Japan).
All patients should be asked about any fever or ongoing infectious or respiratory
symptoms before bronchoscopy. Procedures should be postponed if possible until such
symptoms have resolved or testing (if available) is negative. If procedures cannot
be postponed as determined by the clinical indication, the procedure should be performed
using the precautions as outlined above for bronchoscopy in suspected COVID-19 infection.
In communities with high prevalence of COVID-19 infections, even for routine bronchoscopies
in asymptomatic patients, proper isolation precautions should be adhered to while
also limiting the number of personnel to essential personnel present in either the
bronchoscopy suite or operating room suite with negative pressure room settings or
designated isolation room (Airborne Infection Isolation Room).
Indications for Bronchoscopy in patients with suspected or confirmed COVID-19 infections:
Bronchoscopy is relatively CONTRAINDICATED in patients with suspected and confirmed
COVID-19 infections. The only role for bronchoscopy would be when less invasive testing
to confirm COVID-19 are inconclusive, suspicion for an alternative diagnosis that
would impact clinical management is suspected, or an urgent life-saving intervention
as cited below.
Bronchoscopy for any elective reason should be postponed until after full recovery
and the patient is declared free of infection. Elective indications include a lung
mass, bronchial mass, mediastinal or hilar lymphadenopathy, lung infiltrates, and
mild to moderate airway stenosis.
If immediate testing is not available, bronchoscopy should be deferred if possible.
Bronchoscopy (flexible and rigid) for urgent/emergent reasons should be considered
only if a lifesaving bronchoscopic intervention is deemed necessary. Indications include
massive hemoptysis, benign or malignant severe airway stenosis or suspicion of an
alternative or secondary infectious etiology or malignant condition with resultant
significant endobronchial obstruction.
