Principles of good practice in the prevention and control of infection — iCan Qualifications Limited End-Point Assessment Health & Social Care Revision
This unit focuses on the essential principles that underpin effective infection control in health and social care workplaces, including standard precaution
Topic Synopsis
This unit focuses on the essential principles that underpin effective infection control in health and social care workplaces, including standard precautions, risk assessment, and the chain of infection. It emphasizes the critical role of personal hygiene, particularly hand washing techniques, and the correct use of personal protective equipment (PPE) to safeguard both service users and staff. Mastery of these principles is vital for maintaining a safe environment and meeting regulatory standards such as those set by the Care Quality Commission (CQC) and Health and Safety Executive (HSE).
Key Concepts & Core Principles
- The chain of infection: understanding the six links (infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, susceptible host) and how breaking any link prevents infection.
- Standard precautions: a set of infection control practices including hand hygiene, use of PPE, safe handling of sharps, and environmental cleaning, applied to all patients regardless of diagnosis.
- Hand hygiene: the single most effective way to prevent infection, including the correct technique (e.g., using soap and water or alcohol-based hand rub) and the '5 moments for hand hygiene'.
- Waste management: proper segregation, handling, and disposal of clinical waste (e.g., sharps, infectious waste) to prevent contamination and comply with legal requirements.
- Roles and responsibilities: care workers must follow employer policies, report hazards, and participate in training; employers must provide resources and a safe working environment.
Exam Tips & Revision Strategies
- When answering scenario-based questions, always reference the chain of infection and identify the most vulnerable points for breaking it, citing specific workplace examples.
- For practical assessments, rehearse the correct hand washing technique with a focus on each step: palm-to-palm, backs of hands, interdigital spaces, thumbs, fingertips, and wrists, and time yourself to ensure at least 20 seconds.
- Use the correct terminology: 'donning' for putting on PPE and 'doffing' for removal, and explain the rationale for the order (e.g., gown first, then mask, goggles, gloves) to avoid self-contamination.
- Link infection control practices to workplace policies and national guidelines, such as those from the HSE, NICE, or the WHO 'Five Moments for Hand Hygiene', to show applied knowledge.
Common Misconceptions & Mistakes to Avoid
- Confusing standard precautions with transmission-based precautions, leading to inappropriate use of PPE for routine tasks.
- Underestimating the importance of hand washing duration, often performing less than the recommended 20 seconds and missing areas like thumbs and fingertips.
- Believing that gloves alone provide complete protection without proper hand hygiene, leading to cross-contamination between tasks.
- Failing to recognise that personal hygiene elements like long nails, nail varnish, and wristwatches can compromise infection control even when hand washing is performed correctly.
Examiner Marking Points
- Award credit for demonstrating knowledge of the chain of infection and identifying how each link can be broken through infection control measures.
- Assessor to confirm that the learner can correctly describe the sequence and duration for effective hand washing according to WHO guidelines, including all key steps.
- Evidence of understanding when and how to use different types of PPE, including the correct order for donning and doffing, with rationale.
- Demonstrate application of personal hygiene practices, such as covering cuts, appropriate use of uniforms, and avoiding jewellery that can harbour pathogens, linking to workplace policies.
