Importance of Infection Prevention and Control

Importance of Infection Prevention and Control

• Infection prevention and control (IP&C) is crucial to prevent the spread of infections in healthcare settings
• IP&C helps to protect patients, healthcare workers, and visitors from acquiring and transmitting infections
• Effective IP&C practices reduce the risk of morbidity, mortality, and healthcare-associated costs

Modes of Transmission

• Direct contact: touching, shaking hands, or sharing personal items
• Indirect contact: touching contaminated surfaces or objects
• Airborne transmission: through respiratory droplets or aerosols
• Vector-borne transmission: through insects or animals

Chain of Infection

• Infectious agent: a pathogen that can cause infection
• Reservoir: the source of the infectious agent (e.g., person, animal, or environment)
• Portal of exit: the route by which the infectious agent leaves the reservoir
• Mode of transmission: the way the infectious agent is transmitted to a new host
• Portal of entry: the route by which the infectious agent enters the new host
• Susceptible host: the person or animal that can be infected by the infectious agent

Personal Protective Equipment (PPE)

• Types of PPE: gloves, gowns, masks, eye protection, and face shields
• Purpose of PPE: to prevent the transmission of infectious agents
• When to use PPE: based on the type of care, patient's condition, and potential for exposure

Hand Hygiene

• Importance of hand hygiene: the single most effective way to prevent the spread of infections
• When to perform hand hygiene: before and after patient contact, after using the bathroom, and after blowing your nose, coughing or sneezing
• Hand hygiene techniques: rubbing hands with soap and water or using an alcohol-based hand rub

Environmental Cleaning and Disinfection

• Importance of environmental cleaning and disinfection: to reduce the transmission of infections
• Types of surfaces: high-touch surfaces (e.g., bed rails, door handles) and low-touch surfaces (e.g., floors, walls)
• Cleaning and disinfection methods: using cleaning products and disinfectants, following manufacturer's instructions

Sterilization and Disinfection

• Sterilization: the process of destroying all microorganisms
• Disinfection: the process of reducing the number of microorganisms
• Methods of sterilization: autoclaving, dry heat, and ethylene oxide sterilization
• Methods of disinfection: chemical disinfection, ultraviolet (UV) light disinfection, and hydrogen peroxide disinfection

Surveillance and Outbreak Investigation

• Importance of surveillance: to monitor and track infections in healthcare settings
• Types of surveillance: active surveillance, passive surveillance, and sentinel surveillance
• Outbreak investigation: identifying the source, mode of transmission, and implementing control measures to prevent further transmission

• Hand hygiene techniques: rubbing hands with soap and water or using an alcohol-based hand rub

Environmental Cleaning and Disinfection

• Reduces the transmission of infections
• High-touch surfaces (e.g., bed rails, door handles) require frequent cleaning and disinfection
• Low-touch surfaces (e.g., floors, walls) require regular cleaning
• Cleaning and disinfection methods: using cleaning products and disinfectants, following manufacturer's instructions

Sterilization and Disinfection

• Sterilization: destroys all microorganisms
• Disinfection: reduces the number of microorganisms
• Autoclaving, dry heat, and ethylene oxide sterilization are methods of sterilization
• Chemical disinfection, ultraviolet (UV) light disinfection, and hydrogen peroxide disinfection are methods of disinfection

Surveillance and Outbreak Investigation

• Monitors and tracks infections in healthcare settings
• Active surveillance: actively seeks out cases of infection
• Passive surveillance: relies on reporting of infections
• Sentinel surveillance: focuses on specific populations or areas
• Outbreak investigation: identifies the source, mode of transmission, and implements control measures to prevent further transmission
