PPE Use in Healthcare Settings I: Donning

PPE Use in Healthcare Settings I: Donning

Donning PPE must be completed before contact with the patient. This process protects from infectious agents. The sequence and action included in each donning are critical, and the steps must be systematic to avoid exposure to pathogens. The institutional policy also needs to be followed while donning PPE. The pre-donning preparations are gathering equipment, inspecting the PPE equipment for tears, holes, or damage, removing jewelry, removing any garments below the elbows, and tying the hair...

Personal Protective Equipment

Personal Protective Equipment

Personal protective equipment (PPE) is unique clothing or equipment worn by an employee to minimize or prevent exposure to infectious agents. PPE creates a barrier between the employee and the infectious materials. PPE must be readily available in the patient care area. PPE includes gloves, gowns and aprons, masks and respirators, goggles, face shields, shoes, and headcovers:

Hearing

Hearing

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

PPE Use in Healthcare Settings II: Doffing

PPE Use in Healthcare Settings II: Doffing

The sequence of removing or doffing PPE starts with the gloves, as they are the most contaminated. Next is removal of the face shield or goggles, as they would interfere with removing other PPE. Then remove the gown, followed by the mask or respirator. Perform hand hygiene between steps if hands become contaminated and immediately after removing all PPE. Generally, the outside front and sleeves of the isolation gown, the goggles or the mask, the respirator, and the face shield are contaminated.

Summary

Manufacturing workers in New Zealand often fail to use hearing protection devices (HPDs) correctly, leading to noise-induced hearing loss (NIHL). Understanding personal and environmental factors is key to improving HPD use and preventing hearing damage.

Area of Science:

Occupational Health
Audiology
Industrial Hygiene

Background:

Occupational noise exposure is a primary cause of disabling hearing loss globally.
Noise-induced hearing loss (NIHL) incurs significant human and economic costs, particularly in New Zealand's manufacturing sector.
Inconsistent and improper use of hearing protection devices (HPDs) limits their effectiveness in preventing NIHL.

Purpose of the Study:

To investigate the factors influencing HPD usage among manufacturing workers in New Zealand.
To explore the knowledge, attitudes, beliefs, and behaviors of workers regarding noise and HPDs.

Main Methods:

A qualitative study employing semi-structured interviews with a purposive sample of 25 manufacturing workers.
Conventional content analysis was used to identify key themes related to HPD use.

Main Results:

Five major themes emerged: perception of noise, hearing preservation, reluctance to use HPDs, workplace interaction, and value of hearing.
Both personal and environmental factors were identified as influencing HPD use, acting as either facilitators or barriers.
Themes highlighted specific barriers and enablers to consistent and proper HPD use.

Conclusions:

Personal and environmental factors significantly impact HPD use in the manufacturing sector.
Further research utilizing ecological models is recommended to develop targeted interventions promoting HPD use.
Addressing identified factors is crucial for reducing NIHL and its associated consequences.
