Study Notes

Hand Hygiene and Disinfection

The most effective product for hand hygiene is soap and water or an alcohol-based hand rub.
Antiseptic washing is primarily used to reduce the number of microorganisms on the skin.

Disinfection

Chemical agents commonly used for disinfection include quaternary ammonium compounds, phenolics, and iodophors.
The efficacy of the disinfection process is determined by factors such as concentration of the disinfectant, contact time, temperature, and type of microorganisms present.

Sterilization

The most common method used for sterilization of equipment is steam sterilization (autoclaving).
Sterilization is a process that completely eliminates all microorganisms, including spores.

Infection Control and Precautions

Universal precautions aim to avoid transmission of infectious agents from patients to healthcare workers and vice versa.
The level of disinfection needed for patient-care equipment is determined by the device's intended use, the patient's immune status, and the likelihood of transmission.
Antisepsis involves the use of antiseptic agents to reduce the number of microorganisms on the skin or surfaces.
Transmission-based precautions primarily focus on preventing the transmission of infectious agents from patients with known or suspected infections.
Antisepsis is defined as the use of antiseptic agents to reduce the number of microorganisms on the skin or surfaces.

Factors Affecting Disinfection and Sterilization

The time needed for a germicide to destroy microbes is affected by factors such as concentration of the disinfectant, contact time, temperature, and type of microorganisms present.
The efficacy and duration of a disinfectant are affected by factors such as pH, temperature, and presence of organic matter.
The primary focus of infection control through disinfection is to prevent the transmission of infectious agents.

Asepsis and Disinfection

Asepsis refers to the complete absence of microorganisms.
Medical instruments with multiple pieces must be disassembled before disinfection to ensure that all surfaces are properly disinfected.
A crucial consideration for determining the time needed for germicide action is the type of microorganisms present.
