Handwashing I: Introduction and Types of Equipment01:18

Handwashing I: Introduction and Types of Equipment

4.3K
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....

Handwashing II: Pre-procedure and Initial Procedure Steps

1.0K
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...

Hand hygiene01:23

Hand hygiene

3.7K
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.

Standard Precaution

2.1K
Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.
Hand hygiene is the most crucial means to prevent the transmission of disease. Employers are legally required to provide their workers with personal protective equipment (PPE) to minimize exposure or contact with...

PPE Use in Healthcare Settings II: Doffing01:10

PPE Use in Healthcare Settings II: Doffing

1.0K
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.

Area of Science:

  • Microbiology
  • Laboratory Safety
  • Infection Control

Background:

  • Good Microbiological Practices & Procedures (GMPP) are critical for risk control in laboratories, with hand washing being a key component.
  • Current WHO guidelines recommend using disposable paper towels to turn off taps, posing challenges in resource-limited settings.
  • Ambiguous instructions for tap closure in low-resource environments can compromise effective hand hygiene.

Purpose of the Study:

  • To introduce and validate a modified hand washing method suitable for resource-limited laboratory settings.
  • To assess the applicability, implementability, and impact on compliance of the modified hand washing technique.
  • To provide an effective GMPP for infection control in environments lacking disposable paper towels.

Main Methods:

  • A modified hand washing procedure was developed, involving prolonged soap contact (40-60 seconds) with hands and faucets.
  • The efficacy of the modified method was validated using Glo Germ.
  • A survey was conducted among 12 laboratory staff members to evaluate the new technique's effectiveness and user experience.

Main Results:

  • 100% of participants found the modified method more applicable and implementable than the standard WHO technique.
  • 83% of respondents reported increased hand washing compliance after adopting the modified method.
  • The modified method demonstrated effectiveness in reducing contamination when validated with Glo Germ.

Conclusions:

  • The modified hand washing method offers a practical solution for resource-limited laboratories, addressing the challenge of paper towel unavailability.
  • This technique serves as an effective GMPP, promoting better hand hygiene compliance and enhancing overall infection control.
  • The study highlights the adaptability of essential laboratory practices to diverse resource settings.
