Hand Hygiene: Why & How Nurses Make It Matter

Hand hygiene, a cornerstone of infection prevention, is a critical aspect of nursing practice. It's not just about washing hands; it's about understanding the rationale behind it and implementing it effectively. This article delves into the rationale behind hand hygiene in nursing, its importance, techniques, and best practices.

Understanding the Rationale Behind Hand Hygiene

Hand hygiene is not merely a routine task but a scientific necessity. The rationale behind it lies in the fact that our hands are a significant vector for transmitting healthcare-associated infections (HAIs). They can carry and transfer microorganisms, including bacteria, viruses, and fungi, from one patient to another, from the environment to the patient, or vice versa.

Our hands come into contact with numerous surfaces and objects, picking up microorganisms along the way. Without proper hand hygiene, these microorganisms can be transferred to vulnerable patients, leading to infections that can be life-threatening, especially for those with compromised immune systems.

Importance of Hand Hygiene in Nursing

Hand hygiene is the most important measure to prevent HAIs. It's so effective that it can reduce the risk of HAIs by up to 45%. This makes it a cost-effective and evidence-based intervention that all nurses should prioritize.

Moreover, hand hygiene is a key component of patient safety and quality care. It's a simple yet powerful way to demonstrate respect, compassion, and professionalism towards patients. It's also a legal and ethical responsibility, as nurses are obligated to provide safe and effective care to their patients.

When to Perform Hand Hygiene

Hand hygiene should be performed at key moments, as outlined by the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC). These include:

• Before touching a patient
• Before performing an aseptic task (e.g., preparing an injection, handling sterile equipment)
• After touching a patient
• After touching a patient's clothing or bed linens
• After touching a patient's equipment (e.g., blood pressure cuff, stethoscope)
• After touching the patient's immediate environment (e.g., bedrails, over-bed tables)
• After using the toilet
• After blowing your nose, coughing, or sneezing

Hand Hygiene Techniques

The WHO recommends the use of alcohol-based hand sanitizers (ABHS) or soap and water for hand hygiene. The choice between the two depends on the clinical situation and the availability of ABHS.

ABHS are effective against most microorganisms and are faster and more convenient to use than soap and water. However, they are not effective against all types of microorganisms, such as Clostridium difficile spores and norovirus. In such cases, soap and water should be used.

Using Alcohol-Based Hand Sanitizers

When using ABHS, apply the product to the palm of one hand and rub your hands together, covering all surfaces of your hands and fingers. Continue rubbing until your hands are dry. This should take about 20-30 seconds.

Using Soap and Water

When using soap and water, wet your hands first, turn off the tap, apply soap, lather, scrub all surfaces of your hands and fingers for at least 20-30 seconds, rinse under running water, and dry using a clean towel or air dry.

Best Practices for Hand Hygiene

To maximize the effectiveness of hand hygiene, nurses should follow these best practices:

Best Practice	Rationale
Wear gloves when indicated and remove them when no longer needed	Gloves protect hands but can also become contaminated and transfer microorganisms if not used correctly
Use personal protective equipment (PPE), including gloves, gowns, and masks, when caring for patients with infectious diseases	PPE protects both the nurse and the patient from cross-transmission of microorganisms
Avoid touching your face, especially your eyes, nose, and mouth	These areas are portals of entry for microorganisms
Practice good cough etiquette	Coughing and sneezing can spread microorganisms
Educate patients and their families about the importance of hand hygiene	Patient education promotes adherence to hand hygiene practices and reduces the risk of HAIs

Hand hygiene is a complex yet critical aspect of nursing practice. It's not just about washing hands; it's about understanding the rationale behind it, knowing when and how to perform it, and adhering to best practices. By doing so, nurses can prevent HAIs, promote patient safety, and provide high-quality care.
