Aerosol-Generating Procedures and Risk of Transmission of Acute Respiratory Infections : A Systematic Review

Last updated: November 30, 2011
Project Number: RD0023
Product Line: Rapid Response
Research Type: Drug
Report Type: Systematic review
Result type: Report

Question

  1. What is the clinical evidence for the risk of transmission of acute respiratory infections to health care workers caring for patients undergoing aerosol-generating clinical procedures, compared with the risk of transmission to health care workers caring for patients not undergoing aerosol-generating procedures?

Key Message

Very low-quality evidence suggests that some procedures potentially capable of generating aerosols have been associated with increased risk of SARS transmission of SARS-CoV from infected patients to HCWs, with the most consistent association across several studies being with tracheal intubation.
