Surgeons help create new process for disinfecting and reusing N95 masks
CHICAGO (April 28, 2020): Amid shortages of personal protective equipment due to the Coronavirus Disease 2019 (COVID-19) pandemic, a St. Louis health care system has implemented a process to disinfect disposable N95 respirator masks that allows health care workers to reuse their own mask for up to 20 cycles. The novel disinfection process, developed in collaboration with Washington University School of Medicine, uses vaporized hydrogen peroxide and is described in an “article in press” on the Journal of the American College of Surgeons website in advance of print.
Test results from a pilot program at Barnes-Jewish Hospital and two other hospitals that are also part of BJC HealthCare, showed that the disinfection process kills germs from N95 masks while ensuring that the only person who touches the mask is the original mask wearer, study authors reported.
“Our primary outcome is safety for the health care worker,” said project leader and study coauthor Andrew Pierce, MHSA, director of supply plus at Barnes-Jewish. “We want to make it safer for team members who are at risk while taking care of patients with a known or possible COVID-19 diagnosis.”
Their program uses a disinfecting procedure first tested by Duke University researchers in 2016.1 However, the Barnes-Jewish process has a unique modification–an identification system that enables the hospital to return the sanitized mask to the same individual each time, said senior author Shaina Eckhouse, MD, FACS, assistant professor of surgery at Washington University School of Medicine, St. Louis. Dr. Eckhouse is part of the multidisciplinary team of university and hospital staff who developed the disinfection…
