Infection prevention professionals in healthcare are voicing concerns over the fresh set of guidelines being updated by the Centers for Disease Control and Prevention’s (CDC) advisory committee. This apprehension stems from a fear that these changes may decrease protection against Coronavirus and other airborne pathogens within the hospital environment.
The committee, tasked with revising its 2007 standards for infection control, sparked a wave of dismay within the healthcare community when an iteration of new proposals was publicly released in June. A contentious point was the committee’s assertion that N95 respirators and surgical masks hold equal efficacy in specific circumstances. They concluded that healthcare staff only require surgical masks during treatment of patients suffering from ‘common, endemic’ viruses such as those causing seasonal flu. The vote on these changes, initially scheduled for August 22, was delayed until November. After the draft guidelines become final, the CDC will then work towards transforming them into enforceable rules that hospitals across the nation generally adhere to.
Post-meeting, there was a surge in public anxiety regarding the direction the CDC is taking with these guidelines, especially considering the rise in Covid-19 cases nationwide and an increased rate of hospitalizations and deaths from the virus. Gwendolyn Hill, a Cedars-Sinai Medical Center research intern, emphasized the importance of N95 masks, ventilation, and air-purifying technology in minimizing Covid-19 transmission within hospitals. She advocated for an environment where patients do not risk leaving hospitals in a worsened health condition.
The CDC responded to the criticism through Alexander Kallen, chief of the Prevention and Response Branch in the CDC’s Division of Healthcare Quality Promotion. He expressed gratitude for the feedback and reiterated that the draft guidelines are not yet final. They are committed to creating guidelines that protect patients, visitors, and healthcare workers.
Critics point out that the new guidelines contradict previous studies and reports. The CDC’s own 2022 report revealed N95 masks reduced the risk of testing positive for the virus by 83%, compared to 66% for surgical masks. A 2017 clinical trial also demonstrated N95 masks’ superiority over surgical masks in safeguarding healthcare workers from influenza infections.
Additionally, an assessment by the Royal Society found that N95 respirators were more efficient against Covid-19 compared to surgical masks.
Dr. Kaitlin Sundling, a physician and pathologist at the University of Wisconsin-Madison, argued that the efficacy of N95 respirators against airborne pathogens is well-established, making the suggestion for more studies unnecessary. Ultimately, the path the CDC chooses to follow with these updated guidelines will have significant impact on infection prevention in healthcare environments.
