Characteristics Associated With Health Care Worker Knowledge and Confidence in Elastomeric Half-Mask Respirator Use

Area of Science:

• Occupational Health
• Infection Control
• Respiratory Protection

Background:

• Elastomeric half-mask respirators (EHMRs) are crucial personal protective equipment for healthcare workers (HCWs).
• Assessing HCWs' knowledge and confidence in EHMR usage is vital for ensuring proper protection against airborne pathogens.
• Factors influencing the effective use of EHMRs require thorough evaluation within healthcare settings.

Purpose of the Study:

• To evaluate the knowledge and confidence levels of healthcare workers (HCWs) regarding elastomeric half-mask respirator (EHMR) usage.
• To identify specific EHMR attributes that influence HCWs' adoption and proficiency.
• To assess the correlation between knowledge, confidence, and competency in EHMR donning and doffing.

Main Methods:

• A survey was administered to healthcare workers (HCWs) to gather data on their experience with elastomeric half-mask respirator (EHMR) donning and doffing.
• Respondents were classified into distinct competency categories based on their survey scores.
• Statistical analyses, including chi-squared tests and multiple logistic regression, were employed to analyze differences between competency categories.

Main Results:

• A significant majority of HCWs (72%) exhibited high levels of knowledge and confidence (mastery) in EHMR use.
• A notable percentage of HCWs (21%) displayed greater confidence than actual knowledge, a state termed 'misinformed'.
• Respiratory therapists showed higher odds of achieving mastery compared to other HCWs (P < 0.05), while those in medical/surgical and pediatric units had greater odds of doubt (P < 0.01).

Conclusions:

• While most HCWs possess adequate knowledge and confidence in EHMRs, a subset remains misinformed.
• Implementing strategies to verify respirator use competency is essential for enhancing HCW protection.
• Targeted training and assessment may be necessary for specific HCW groups to ensure consistent and effective EHMR utilization.
