COVID-19: PPE, Training Down Risk among Health Care Workers
COVID-19 infection rate among health care workers can be lowered by using personal protective equipment along with proper training in infection control, according to researchers at Oregon Health & Science University.
The review, funded by the World Health Organization, published in the Annals of Internal Medicine.
‘Providing the equipment, helping health care workers understand how they have to use it, training and education were associated with decreased risk of coronavirus infection among them.’
"Most people understand it's a high priority to protect our nurses and doctors," said senior author Roger Chou, M.D., director of the Pacific Northwest Evidence-based Practice Center at OHSU and a professor of medicine (general internal medicine and geriatrics) in the OHSU School of Medicine.
"In addition to the impact that COVID-19 would have on infected health care workers, they can pose a transmission risk. Plus, they can't work if they become infected, and maintaining health care capacity throughout the pandemic is important."
Adequate supplies of personal protective equipment such as masks, gowns and eye protection have been the subject of heightened attention throughout the pandemic. Chou said the evidence suggests that lowering the rate of infection among health care workers must also include adequate training and education to ensure workers use the equipment properly.
"Infection control training is important," Chou said. "It's not just about providing the equipment, but helping health care workers understand how they need to use it. Training and education were consistently associated with decreased risk of infection."

The researchers will continue to track new evidence and update the findings as a "living rapid review."
Chou noted that the SARS-Cov-2 virus appears to be much more transmissible than the strains involved in the previous outbreaks of SARS and MERS. With some health care workers staying in hotels to isolate themselves from family members, researchers looked for evidence about the risk of transmission in their own homes.
"Unfortunately, we have no data yet for risk factors on health care workers transmitting the infection to household contacts," Chou said. "That's a big area we need to understand in order to reduce risk of transmission from health care workers to family members and other close contacts."
