What is this? The COVID-19 pandemic has highlighted occupational risks for healthcare workers, including those associated with aerosol generating procedures (AGPs), such as endotracheal intubation, airway suction, chest physiotherapy, and nebulizer treatment. Existing research on these risks might provide useful information for policy makers concerned about the transmission of the SARS-Cov-2 virus.

In this systematic review, the authors searched for research into the associations between AGPs and acute respiratory infection in healthcare workers. They searched for studies published between 1990 and October 2010. They included 5 case-control studies and 5 cohort studies.

What was found: Some AGPs have been linked with high risk of acute respiratory disease (such as SARS) among frontline healthcare workers.

Among the AGPs studied, tracheal intubation was linked with the highest risk of transmission to healthcare workers.

Other AGPs identified with potential occupational risk included cardiopulmonary resuscitation and non-invasive ventilation.
