Principles of the importance of personal hygiene and health in the prevention and control of infection in health care settings
This element focuses on the critical role of personal hygiene, particularly hand hygiene and appropriate use of PPE, in breaking the chain of infection in health care settings. It underpins the practical skills needed to safeguard patients, staff, and visitors from healthcare-associated infections, emphasising evidence-based protocols and personal responsibility.
Assessment criteria
Topic Overview
The TQUK Level 2 Certificate in the Principles of the Prevention and Control of Infection in Health Care settings (RQF) is a foundational qualification for anyone working in health and social care. It covers the essential knowledge and skills required to prevent and control the spread of infections in healthcare environments, including hospitals, care homes, and community settings. The course is designed to ensure that learners understand the chain of infection, standard infection control precautions, and the importance of hand hygiene, personal protective equipment (PPE), and safe waste disposal.
This qualification is critical because healthcare-associated infections (HCAIs) are a major cause of morbidity and mortality, and they place a significant burden on the NHS. By understanding how infections spread and how to break the chain, healthcare workers can protect themselves, their colleagues, and vulnerable patients. The course aligns with national guidelines from the Department of Health and the Health and Safety Executive, and it is a mandatory requirement for many roles in health and social care.
Within the wider subject of Health & Social Care, this certificate provides the underpinning knowledge for safe practice. It complements other qualifications in areas such as safeguarding, health and safety, and person-centred care. Mastery of infection prevention and control is not just a regulatory requirement but a fundamental aspect of delivering high-quality, compassionate care.
Key Concepts
Core ideas you must understand for this topic
- →The chain of infection: understanding the six links (infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, susceptible host) and how to break each link.
- →Standard infection control precautions (SICPs): including hand hygiene, use of PPE, safe management of blood and body fluids, and safe disposal of waste.
- →Hand hygiene: the correct technique for hand washing (using the WHO 'My 5 Moments for Hand Hygiene') and when to use alcohol-based hand rubs versus soap and water.
- →Personal protective equipment (PPE): correct selection, use, and disposal of gloves, aprons, masks, and eye protection to prevent cross-contamination.
- →Safe management of sharps: procedures to prevent needlestick injuries, including safe disposal in sharps bins and reporting of incidents.
Learning Objectives
What you need to know and understand
- Understand the importance of personal hygiene in the prevention and control of infection in a workplace setting, Understand the importance of effective hand washing, Understand the principles of using Personal Protective Equipment (PPE)
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for explaining how micro-organisms are transmitted via hands and the consequences of poor hand hygiene in a healthcare environment.
- Award credit for demonstrating the correct sequence and technique for hand washing as per the World Health Organization (WHO) '5 Moments for Hand Hygiene'.
- Award credit for accurately describing when and how to select and apply different types of PPE (gloves, aprons, masks) based on risk assessment and infection control policies.
Assessment Guidance
Guidance for achieving higher grades
- 💡In written assessments, always link your answers to the chain of infection and how personal hygiene breaks the chain at specific points.
- 💡For practical assessments, narrate your actions as you perform hand washing or don/doff PPE to demonstrate understanding of rationale, not just manual skill.
- 💡Use the exact terminology from infection control guidelines (e.g., 'aseptic technique', 'standard precautions') to show professional competence.
- 💡When answering questions about the chain of infection, always explain how each link can be broken. For example, hand hygiene breaks the mode of transmission, and vaccination reduces the number of susceptible hosts. This shows a deeper understanding.
- 💡For questions on PPE, remember the order of donning and doffing. Donning: apron, mask, eye protection, gloves. Doffing: gloves, apron, eye protection, mask. This sequence minimises self-contamination.
- 💡Use specific terminology from the course, such as 'aseptic technique', 'cohort nursing', and 'isolation precautions'. Examiners reward the use of correct technical language.
Common Mistakes
Common errors to avoid in your coursework
- Believing that hand washing is only necessary when hands are visibly soiled, overlooking the importance of hand hygiene after removing gloves or before aseptic tasks.
- Confusing the steps in the hand washing procedure or missing key areas such as thumbs, fingertips, and wrists.
- Assuming that wearing gloves replaces the need for hand hygiene, leading to contamination when gloves are removed.
- Misconception: Alcohol-based hand rubs are always better than soap and water. Correction: Alcohol-based rubs are effective against most pathogens but are not effective against spores (e.g., Clostridium difficile) or some viruses (e.g., norovirus). Soap and water must be used when hands are visibly soiled or after caring for patients with these infections.
- Misconception: Wearing gloves means you don't need to wash your hands. Correction: Gloves can have microscopic holes and can become contaminated during removal. Hand hygiene must be performed before putting on gloves and immediately after removing them.
- Misconception: Infection prevention is only important in hospitals. Correction: Infections can spread in any healthcare setting, including care homes, clinics, and community care. The same principles apply to all environments where care is provided.
