Principles of infection prevention and control in a health care setting
This element explores the fundamental principles of infection prevention and control within health care settings, focusing on the purpose of reducing healthcare-associated infections, the influence of legislation and national guidelines on local policies, the distinct roles and responsibilities of staff, and the systematic use of risk assessments to identify and mitigate infection hazards. It also covers the essential procedures such as hand hygiene, use of personal protective equipment, and safe waste management that form the basis of effective infection control practice.
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 or aspiring to work in health and social care. It covers the essential knowledge required to prevent and control the spread of infections in settings such as hospitals, care homes, and community care environments. The course emphasises the importance of infection prevention as a key component of patient safety and public health, addressing both legal and ethical responsibilities of care workers.
This qualification is structured around key principles including the chain of infection, standard infection control precautions (SICPs), and the role of risk assessment in reducing infection risks. Students learn about the causes of infections, how they spread, and the practical measures—such as hand hygiene, use of personal protective equipment (PPE), and safe disposal of waste—that break the chain of infection. The content aligns with national guidelines from the Department of Health and the Health and Safety Executive, ensuring learners are equipped with current best practices.
Understanding infection prevention is critical in health and social care because healthcare-associated infections (HCAIs) pose significant risks to vulnerable individuals. By mastering these principles, students contribute to safer care environments, reduce the burden on the NHS, and enhance their own employability. This certificate also provides a stepping stone to further qualifications in health and social care, such as the Level 3 Diploma in Healthcare Support.
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 breaking any link prevents infection.
- →Standard infection control precautions (SICPs): hand hygiene, use of PPE, safe management of blood and bodily fluids, safe disposal of waste (including sharps), and environmental cleaning.
- →Risk assessment: identifying hazards (e.g., contaminated equipment, poor hand hygiene), evaluating risks, and implementing control measures to minimise infection spread.
- →Roles and responsibilities: the duty of care workers to follow policies, report incidents, and protect themselves and others under the Health and Safety at Work Act 1974.
Learning Objectives
What you need to know and understand
- Understand the purpose of infection control, Know how regulations inform policy and practice relating to infection control, Understand the roles and responsibilities relating to infection control, Understand the role of risk assessments in relation to infection control, Understand the principles of infection control procedures
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for clearly explaining the chain of infection and how breaking any link at any stage can prevent the spread of microorganisms.
- Look for accurate referencing of key regulations (e.g., Health and Social Care Act 2008, COSHH, RIDDOR) and explicit linkage between regulatory requirements and local policy implementation.
- Require a distinction between individual responsibilities (e.g., adherence to hand hygiene protocols) and organisational responsibilities (e.g., providing training and resources) when discussing roles.
- Check that the learner describes the systematic process of risk assessment: identifying infection hazards, evaluating risk levels, implementing proportionate control measures, and monitoring effectiveness.
- Insist on detailed explanations of standard infection control precautions, including correct sequence of donning and doffing PPE, and the rationale for each step.
Assessment Guidance
Guidance for achieving higher grades
- 💡When citing regulations, always provide a practical example of how the regulation translates into daily infection control practice, such as COSHH requiring safe disposal of sharps.
- 💡Use current terminology such as 'standard infection control precautions' (SICPs) rather than outdated terms like 'universal precautions' to demonstrate up-to-date knowledge.
- 💡In scenario-based questions, explicitly state how the chosen control measure reduces the specific risk identified, rather than providing a generic list of control measures.
- 💡Clearly articulate the boundaries of your own role and when to escalate infection control concerns to a supervisor or infection control lead to show understanding of accountability.
- 💡When answering questions about the chain of infection, always use the full terminology (e.g., 'portal of exit' not just 'exit') and give a specific example for each link, such as 'the respiratory tract as a portal of exit for influenza virus.' This demonstrates precise knowledge.
- 💡For questions on standard precautions, structure your answer around the key categories: hand hygiene, PPE, waste management, and environmental cleaning. Mentioning the '5 Moments for Hand Hygiene' and the colour-coding system for waste (e.g., orange for infectious waste) can earn you extra marks.
- 💡In risk assessment questions, use the 'hazard, risk, control measure' framework. For instance, 'hazard: contaminated sharps; risk: needlestick injury and bloodborne infection; control: use of sharps bins and safe disposal procedures.' This shows you can apply theory to practice.
Common Mistakes
Common errors to avoid in your coursework
- Confusing colonisation with infection, leading to underestimation of the need for standard precautions in asymptomatic carriers.
- Incorrectly sequencing the donning and doffing of PPE, particularly removing gloves before the gown and neglecting hand hygiene between steps.
- Overlooking the role of contaminated environmental surfaces and equipment in the transmission of pathogens, focusing solely on direct person-to-person contact.
- Treating risk assessments as a one-off paperwork exercise rather than a dynamic process that should be reviewed regularly and updated in response to changes in the care environment or client condition.
- Misconception: Hand washing is only necessary after visible dirt or after using the toilet. Correction: Hand hygiene must be performed before and after every patient contact, after removing gloves, and after touching contaminated surfaces, even if hands look clean. The '5 Moments for Hand Hygiene' (WHO) should be followed.
- Misconception: Wearing gloves means you don't need to wash your hands. Correction: Gloves are not a substitute for hand hygiene. Hands must be washed before putting on gloves and immediately after removing them, as gloves can have microscopic holes or become contaminated during removal.
- Misconception: All infections are spread through the air. Correction: Many infections spread via contact (direct or indirect), droplet, or bloodborne routes. For example, MRSA is often spread by direct contact with contaminated hands or surfaces, not through the air.
