Summary
Providing washcloths significantly improves mass-casualty decontamination, reducing contaminant levels by approximately 20%. This simple addition optimizes current procedures for emergency responders and vulnerable populations like children.
Area of Science:
- Emergency Medicine
- Public Health
- Environmental Health
Background:
- Mass-casualty decontamination is crucial for protecting emergency responders and healthcare facilities.
- Mobile showering units are established in the UK for large-scale decontamination.
- Optimizing decontamination effectiveness is vital for public safety.
Purpose of the Study:
- To evaluate empirical strategies for enhancing mass-casualty decontamination procedures.
- To assess the impact of pictorial instructions, washcloths, and extended showering times.
- To identify simple, effective methods for improving decontamination efficacy.
Main Methods:
- A three-factor, between-participants study involving 90 volunteers.
- Factors included washcloth use, pre-decontamination instructions, and shower duration (3 vs. 6 minutes).
- Decontamination effectiveness was measured using whole-body fluorescence imaging after applying a red fluorophore.
Main Results:
- All tested showering protocols demonstrated effectiveness in contaminant removal.
- The use of a washcloth, without instructions, significantly improved decontamination effectiveness by approximately 20% (p < 0.05).
- Washcloths provided a measurable enhancement over the standard decontamination protocol.
Conclusions:
- Provision of a washcloth is a simple yet effective method to optimize mass-casualty decontamination.
- This strategy is particularly beneficial for improving decontamination in children.
- Controlled volunteer trials are valuable for refining existing public health procedures.

01:23Hand hygiene
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.

01:19Handwashing II: Pre-procedure and Initial Procedure Steps
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 paint...

01:30Cleaning, Sterilization, and Disinfection
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...

01:18Handwashing I: Introduction and Types of Equipment
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.

01:10PPE 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.
