Study Notes
Nosocomial Infection Control through Hand Hygiene Protocols
Nosocomial infections are infections acquired in healthcare settings by patients, usually as a result of medical procedures, devices or medications. These infections are associated with increased morbidity and mortality rates among hospitalized patients, leading to higher costs and longer stays. Therefore, maintaining strict standards for nosocomial infection control is critical for patient safety. This article explores various aspects of hand hygiene protocols that are essential in reducing the spread of nosocomial infections.
Hand hygiene is the most important measure to prevent the transmission of pathogens in hospitals and other healthcare facilities. Healthcare workers are expected to clean their hands before every procedure involving patient contact, after any exposure to body fluids, after using gloves, after removing gloves, after touching contaminated surfaces and objects, and before leaving the area where they have been working. Failure to follow these guidelines can lead to serious consequences such as hospital-acquired sepsis and pneumonia.
A study published in The Lancet emphasizes the importance of proper hand washing in preventing nosocomial infections. The study analyzed a total of 8,990 children who were admitted to 113 hospitals across Europe. It was found that there was a significant association between poor hand hygiene practices and colonization or infection by methicillin-resistant Staphylococcus Aureus (MRSA), Clostridium difficile, and vancomycin-resistant enterococci (VRE).
To promote the adoption of effective hand hygiene protocols, several organizations have developed guidelines based on evidence-based principles. These guidelines provide standardized recommendations for hand hygiene in different scenarios, ensuring adequate protection against nosocomial infections. Some of these organizations include:
- World Health Organization (WHO)
- Centers for Disease Control and Prevention (CDC)
- European Centre for Disease Prevention and Control (ECDC)
WHO Guidelines
The WHO has published guidelines recommending the use of alcohol-based hand sanitizers when soap and water are unavailable. According to the WHO guidelines, the first step in hand hygiene involves wetting hands with water and applying enough friction-inducing agent to cover all parts of the hands. Next, the hands should be rubbed together to create a lather covering all areas, including the back of the hands, between fingers and under nails. After rubbing for a minimum of 20 seconds, hands should be rinsed thoroughly with running water and dried using disposable paper towels.
CDC Guidelines
The CDC's hand hygiene guidelines recommend using either hand hygiene products containing alcohol (at least 60% ethanol or at least 70% isopropyl alcohol) if hands are visibly dirty or not visibly clean after handwashing with soap and water. Alcohol-based hand rubs do not require water and are more conveniently available in settings like intensive care units (ICUs) where continuous access to sinks may not always be feasible. However, alcohol-based hand sanitizers are less effective in removal of some types of bacteria and viruses.
ECDC Guidelines
The ECDC has also issued guidelines on hand hygiene, which are similar to those recommended by the WHO. They suggest an initial hand hygiene procedure involving wetting the hands, applying a sufficient amount of friction-promoting substance, rubbing hands together, and rinsing and drying them afterwards. If soap and water are not available, alcohol-based handrubs with a concentration of at least 60% alcohol can be used as an alternative.
In conclusion, nosocomial infection control measures should prioritize hand hygiene protocols to reduce the risk of transmitting pathogens within healthcare facilities. Adherence to established guidelines from organizations such as the WHO, CDC, and ECDC is crucial in implementing effective hand hygiene practices among healthcare professionals. By following these guidelines consistently, we can help maintain a safer environment for both patients and healthcare providers.
