PPE Use in Healthcare Settings II: Doffing

1.5K
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.

Handwashing II: Pre-procedure and Initial Procedure Steps

1.4K
The pre-procedure steps of handwashing include removing jewelry and rolling up sleeves. However, many organizations allow staff to wear wedding rings.
The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury.  The nails must be short and clean, without nail...

Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease.
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...

Handwashing I: Introduction and Types of Equipment

4.8K
Handwashing is hand hygiene with plain or antimicrobial soap and water to physically remove dirt, organic material, and microorganisms. However, it may not kill all microorganisms. The handwashing procedure requires a hand wash basin, liquid soap, paper towels, a domestic waste bin, and disposable nail cleaner as optional equipment.
Hand wash basins in clinical areas should have faucets that can be turned on and off without using the hands; that is, they should be non-touch or lever-operated....

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Area of Science:

  • Occupational Health
  • Ergonomics
  • Public Health

Background:

  • Cleaning workers report significant musculoskeletal symptoms.
  • High prevalence of symptoms in shoulders, elbows, and lower back observed.
  • Multiple cleaning tasks contribute to symptom development.

Purpose of the Study:

  • Examine musculoskeletal symptoms in cleaners of varying heights.
  • Evaluate the impact of worker height on occupational postures.
  • Assess ergonomic risks within school cleaning environments.

Main Methods:

  • Utilized the Nordic Musculoskeletal Questionnaire (NMQ) for symptom assessment.
  • Conducted task analysis to identify typical cleaning activities.
  • Employed the OVAKO Working Posture Assessment System (OWAS) for posture evaluation.
  • Applied multinomial logistic regression to analyze individual characteristics' effects on pain.

Main Results:

  • Musculoskeletal symptoms are highly prevalent among cleaners.
  • Height differences lead to varied work demands and postures.
  • Awkward postures are strongly linked to reported symptoms.
  • Men and lower national economic indicators showed higher odds of multiple risk factors.

Conclusions:

  • Recommends job adaptations and targeted occupational safety training.
  • Highlights the need for height-specific tools and posture guidance.
  • Suggests using findings for improved operational designs and task modifications.
  • Emphasizes ensuring correct tool use and safer working postures.
