Principles of infection prevention and control

Respiratory Protective Equipment Administrative Measures Administrative controls are the first and most important level of the hierarchy. These are management measures that are intended to reduce the risk or exposure to persons with infectious TB. These control measures consist of the following activities:

Principles of infection prevention and control

Basic Principles Introduction Infection prevention and control is the application of microbiology in clinical practice. Infection can be caused by bacteria, fungi, viruses or prions and can affect almost all body systems.

Understanding how infections occur and how different micro-organisms spread is crucial to preventing infection. Healthcare-associated infections HCAIs can occur in any healthcare setting. While the specific risks may differ, the basic principles of infection prevention and control apply regardless of the setting.

Although infections can spread easily, controlling the risk is relatively straightforward and simple measures can be effective. It is important that all members of staff have a clear understanding of their role in preventing the spread of infection.

Courses should be mandatory and all staff, including nursing and medical staff, should attend. The chain of infection The process of infection can be represented as a chain, along which microorganisms are passed from a source to a vulnerable person. Breaking a link at any point in the chain will control the risk of infection by preventing the onward transmission of microorganisms.

Opportunities to break the chain of infection Transmission may be interrupted when: The infectious agent is eliminated, inactivated or cannot survive in the reservoir E. Hand Hygiene, appropriate use of PPE, safe packaging and disposal of waste Transmission does not occur due to good infection prevention and control practices E.

Hand Hygiene, isolation of infected patients, air flow control where appropriate The portal of entry is protected E. Aseptic non-touch technique, safe catheter care, wound care Reducing the susceptibility of patients receiving healthcare E. Treatment of underlying disease, recognising high risk patients The difference between Colonisation and Infection Colonisation Colonisation is when microorganisms, including those that are pathogenic, are present at a body site E.

For example, the skin is normally colonised by coagulase negative Staphylococci and can also be colonised by pathogenic Staphylococcus aureus.

Infection Infection is the process where an infectious agent microorganism invades and multiplies in the body tissues of the host resulting in the person developing clinical signs and symptoms of infection E.

Increased temperature, rigors, rash.The focus of the Principles of Infection Prevention and Control course is to introduce behavioural change and the integration of skills and knowledge into clinical practice.

Entry Criteria The course is designed for all personnel working within a clinical environment. Standard Principles provide guidance on infection control precautions that should be applied by all healthcare workers to the care of patients in community and primary care settings.

These recommendations are broad principles of best practice and are not detailed procedural protocols.

Most of the legal regulations relating to infection prevention and control come under the Health and Safety at Work Act. The Management of Health and Safety at Work Regulations introduced the need for monitoring health and safety and risk assessment.

Apr 26,  · The TB infection control program should be based on a three-level hierarchy of control measures and include: Applying epidemiology-based prevention principles, including the use of setting-related TB infection-control data; Primary environmental controls consist of controlling the source of infection by using local .

This optional unit assesses the care worker's knowledge of national and local infection control policies; of employer and employee infection control responsibilities and of how procedures and risk assessment can help minimise the risk of an outbreak of infection.
