Study | Study design | Overview | Population | Summary |
---|---|---|---|---|
Tran et al, 2012, Canada13 | Systematic review | Transmission of SARS-CoV to healthcare workers | 5 case-control studies, 5 cohort studies | Chest compressions are not considered to increase the rate of transmission of acute respiratory infections |
Liu et al, 2009, China22 | Case-control study | Possible risk factors of SARS transmission | 477; 51 infected | Chest compressions were associated with a 33% risk of contracting SARS, compared with 11% that did not contract SARS |
Raboud et al, 2010, Canada23 | Retrospective cohort study | SARS transmission in cohort with close contact to airway of SARS patient and failure of infection control practices | 697; 26 infected | Out of 26 infected HCWs, one was involved in chest compressions. Eight of the control group performed chest compressions and did not contract SARS |
Loeb et al, 2004, Canada24 | Retrospective cohort study | Risk of SARS infection in critical care nurses | 32 nurses; 8 infected | Three nurses were involved in chest compressions and none contracted SARS |
Christian et al, 2004, Canada26 | Cross-sectional study | Possible cluster of SARS-CoV infections in HCWs during CPR | 9; 3 symptomatic, 1 confirmed infection | Risk of transmission through chest compressions difficult to establish due to multiple confounding factors, refusal of serological testing and small sample size |
Nam et al, 2015, Korea25 | Case study | MERS infection of 1 HCWs contracted while performing CPR | 1 | Identified three possible routes of infection transmission during CPR in this case, including the generation of aerosols |
Ott et al, 2020, Germany27,28 | Simulation (Two studies) | Aerosol spread during chest compressions in dummy and cadaver models | – | Limited applicability as not yet peer-reviewed. Suggested that aerosols may be generated in the direction of the provider during chest compressions |
HCWs = healthcare workers.
