Autopsy, airway suctioning and cardiopulmonary resuscitation are among the list of medical procedures that pose a risk of spreading COVID-19 from a patient to their health-care provider by creating aerosols, according to new research published in the journal BMJ Open Respiratory Research by an international team of experts including occupational health, preventive medicine and infectious disease specialists.
The team, led by University of Alberta medicine professor Sebastian Straube, carried out a systematic review of public health guidelines, research papers and policy documents from around the globe to determine which procedures are classified as aerosol-generating.
“What we sought to do was to understand which procedures generate aerosols and therefore require a higher grade of personal protective equipment,” said Straube, who also heads the preventive medicine division of the Faculty of Medicine & Dentistry.
“Where there is 80 per cent agreement from a number of different source documents, we are reasonably confident
We need to know about these psychological and social profiles so we can understand how protective actions against contagious diseases are adopted, and then define the correct preventive approaches. At the very start of the coronavirus crisis — before restrictive measures were taken — a team of health behaviour specialists from the University of Geneva (UNIGE) managed to collect a large amount of data about the adoption of protective measures.
Through a study published in the journal Applied Psychology: Health and Well-Being, the Geneva psychologists analysed how people in Britain followed the precautions recommended in their country. The study focuses on how the behaviour of others influences individual decision-making, known as the social dilemma. It notes that beliefs about COVID-19, such as thinking that the disease is dangerous or feelings of vulnerability, have little impact on whether or not an individual takes up protective measures.
