A hood shield reduces postdoffing contamination during simulated COVID-19 airway management: an exploratory,...

Area of Science:

• Occupational Health
• Infectious Disease Control
• Medical Simulation

Background:

• Healthcare workers face a threefold increased risk of SARS-CoV-2 infection during aerosol-generating procedures.
• The optimal personal protective equipment (PPE) configuration for minimizing contamination remains unclear.
• Effective PPE is crucial for protecting frontline staff during pandemics.

Purpose of the Study:

• To evaluate the protective efficacy of a novel, locally designed hood-based PPE against surrogate contamination.
• To compare the contamination rates between the novel hood PPE and standard PPE during simulated aerosol-generating procedures.
• To identify PPE configurations that offer superior protection and lower contamination for healthcare workers.

Main Methods:

• An exploratory, simulation-based randomized study involving 40 airway management practitioners.
• Evaluation of a novel hood PPE (n=20) versus standard PPE (n=20) using an ultraviolet marker for contamination.
• Standardized urgent intubation and simulated coughing scenarios were used to assess PPE performance.

Main Results:

• The hood PPE group showed significantly lower residual contamination (40%) compared to the standard PPE group (90%).
• A statistically significant reduction in contamination was observed with the novel hood PPE (P = 0.002).
• Fewer participants using the hood PPE had contamination on clothing or exposed skin after doffing.

Conclusions:

• Enhanced PPE featuring a locally designed prototype hood significantly reduces upper torso contamination.
• The hood PPE demonstrated superior protection against droplet exposure in simulated aerosol-generating scenarios.
• This novel PPE design offers a promising strategy for improving healthcare worker safety.
