Hand hygiene01:23

Hand hygiene

5.4K
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.

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...

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....

Area of Science:

  • Medical Education Technology
  • Infection Prevention and Control
  • Virtual Reality Applications

Background:

  • Hand hygiene is crucial for preventing healthcare-associated infections (HAIs) but adherence is low among HCAs and informal caregivers (ICs).
  • Virtual reality (VR) offers standardized, immersive training with real-time feedback, showing promise for skill development in healthcare settings.
  • VR has not been systematically applied to World Health Organization (WHO)-aligned hand hygiene techniques, presenting an opportunity for improved training.

Purpose of the Study:

  • To assess the immediate training effectiveness of a brief VR hand hygiene program for HCAs and ICs in Colombia.
  • To evaluate the implementation feasibility and quantify pre-post changes in correct execution, timing, errors, and knowledge.
  • To determine if the VR program achieves ≥75% correct execution, a benchmark associated with HAI reduction.

Main Methods:

  • A quasi-experimental, one-group pretest-posttest study involving 215 participants (94 HCAs, 121 ICs).
  • Participants completed up to three 15-minute VR sessions focusing on WHO-aligned hand hygiene techniques with real-time feedback.
  • Data collected pre- and post-intervention included correct execution, error counts, timing adequacy, knowledge, and acceptability.

Main Results:

  • Correct hand hygiene performance dramatically increased from 26.6% to 97.9% for HCAs and 9.9% to 95.9% for ICs (P<.001).
  • Timing adequacy improved significantly, and common errors like insufficient fingertip coverage were nearly eliminated (P<.001).
  • Knowledge scores improved, and VR training was highly rated for skill acquisition.

Conclusions:

  • VR training significantly enhances hand hygiene technique and knowledge in HCAs and ICs.
  • High acceptance rates suggest VR can effectively improve infection prevention skills in undertrained populations.
  • VR is well-suited for scale-up in various healthcare and home-care settings, potentially reducing HAIs when integrated into multimodal strategies.
