Understanding Infection Prevention and Control in Health and Care Settings
This element provides the foundational knowledge required to prevent the spread of infections within health and care environments. Learners explore common pathogens, transmission routes, and the practical application of evidence-based control measures such as hand hygiene, PPE, decontamination, and waste management. Understanding these principles is essential for safeguarding service users, staff, and visitors while meeting legal and regulatory requirements.

Topic Overview
The Highfield Level 2 Award in Understanding Infection Prevention and Control in Health and Care Settings (RQF) provides essential knowledge for anyone working in health and social care. It covers the causes of infections, how they spread, and the measures needed to prevent and control them. This qualification is crucial for reducing healthcare-associated infections (HCAIs) and ensuring the safety of both patients and staff.
The course is divided into key areas: understanding the chain of infection, standard infection control precautions (SICPs), the use of personal protective equipment (PPE), hand hygiene, waste management, and the roles and responsibilities of individuals in infection control. It aligns with national guidelines such as those from the Health and Safety Executive (HSE) and the National Institute for Health and Care Excellence (NICE).
Mastering this topic is vital because infections can lead to serious illness, prolonged hospital stays, and increased healthcare costs. By understanding infection prevention and control, students contribute to a safer care environment, reduce the risk of outbreaks, and uphold professional standards. This knowledge is applicable across all health and care settings, including hospitals, care homes, and community 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 breaking any link prevents infection.
- →Standard infection control precautions (SICPs): including hand hygiene, use of PPE, safe management of blood and body fluids, safe disposal of waste, and respiratory hygiene.
- →Hand hygiene: the correct technique (using the WHO 6-step method), when to perform hand hygiene (e.g., before and after patient contact, after removing gloves), and the importance of using alcohol-based hand rubs or soap and water.
- →Personal protective equipment (PPE): correct selection, use, and disposal of gloves, aprons, masks, and eye protection, and understanding when each is required.
- →Waste management: segregation of clinical waste (e.g., infectious, sharps) into appropriate colour-coded bags and bins, and safe disposal procedures.
Learning Objectives
What you need to know and understand
- Identify six common healthcare-associated infections and their causative agents
- Describe the six links in the chain of infection and state an intervention to break each link
- Demonstrate the World Health Organization’s ‘5 Moments for Hand Hygiene’ in a simulated setting
- Explain the correct sequence and duration for effective hand washing using soap and water
- Select appropriate personal protective equipment for a given care scenario based on risk assessment
- Distinguish between cleaning, disinfection, and sterilisation in the decontamination process
- Outline the colour-coding system for waste segregation in health and care settings
- Summarise the legal and organisational responsibilities of care workers in preventing and controlling infection
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for accurately listing the chain of infection links: infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, susceptible host
- Award credit for describing at least two situations where alcohol-based hand rub is not sufficient (e.g., visibly soiled hands, exposure to spore-forming organisms)
- Award credit for correctly stating the sequence of donning and doffing PPE without causing contamination
- Award credit for explaining the difference between terminal clean and scheduled clean, with an example of each
- Award credit for identifying the correct waste stream for clinical waste, offensive waste, and sharps, including appropriate container selection
Assessment Guidance
Guidance for achieving higher grades
- 💡For multiple-choice assessments, read scenario-based questions carefully: look for cues about the type of infection risk or procedure to determine the appropriate PPE or waste stream
- 💡In written assignments, always link control measures back to specific links in the chain of infection to demonstrate understanding of the rationale
- 💡Practise sequencing for practical demonstrations: incorrect order of donning or doffing PPE is a common reason for lost marks in observed assessments
- 💡When discussing decontamination, clearly state the level required (cleaning, disinfection, or sterilisation) and justify your choice based on risk and item classification
- 💡When answering questions about the chain of infection, always name all six links and give a specific example for each (e.g., infectious agent: bacteria like MRSA). Examiners look for precise terminology.
- 💡For hand hygiene questions, mention the WHO '5 Moments for Hand Hygiene' and the correct duration (20-30 seconds with alcohol rub, 40-60 seconds with soap and water). This shows depth of knowledge.
- 💡In questions about waste management, specify the colour coding: orange for infectious waste, yellow for clinical waste requiring incineration, and purple for cytotoxic waste. Avoid vague terms like 'special waste'.
Common Mistakes
Common errors to avoid in your coursework
- Confusing the portal of exit and portal of entry when describing the chain of infection
- Assuming that wearing gloves eliminates the need for hand hygiene before and after patient contact
- Using alcohol-based hand rub on visibly soiled hands instead of washing with soap and water
- Believing that all PPE is reusable or that single-use items can be decontaminated
- Mixing clinical waste with general waste due to misunderstanding of orange and yellow bag usage
- Mistake: Believing that hand washing with soap and water is always better than alcohol-based hand rub. Correction: Alcohol-based hand rub is more effective against most germs and is preferred when hands are not visibly soiled. Soap and water should be used when hands are visibly dirty or after caring for patients with diarrhoea (e.g., C. difficile).
- Mistake: Thinking that wearing gloves replaces the need for hand hygiene. Correction: Gloves can have microscopic holes and can become contaminated during removal. Hand hygiene must be performed before putting on gloves and after removing them.
- Mistake: Assuming that all PPE must be worn for every patient interaction. Correction: PPE should be based on a risk assessment. For example, a simple consultation may only require gloves, while an aerosol-generating procedure requires a mask and eye protection.
