Healthcare Associated Infections II: Preventive Measures01:22

Healthcare Associated Infections II: Preventive Measures

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...
Hand hygiene01:23

Hand hygiene

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Transmission-based Precautions II: Airborne and Protective Environment01:25

Transmission-based Precautions II: Airborne and Protective Environment

Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...
Standard Precaution01:26

Standard Precaution

Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.
Hand hygiene is the most crucial means to prevent the transmission of disease. Employers are legally required to provide their workers with personal protective equipment (PPE) to minimize exposure or contact with...

Transmission-based Precautions I: Contact, Enteric, and Droplets

Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...
Cleaning, Sterilization, and Disinfection01:30

Cleaning, Sterilization, and Disinfection

Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease.
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...

Area of Science:

  • Infection Control
  • Hospital Hygiene
  • Environmental Services

Background:

  • Environmental contamination in intensive care units (ICUs) is a significant route for multidrug-resistant organism (MDRO) transmission.
  • Thorough terminal cleaning of patient rooms is crucial for breaking the chain of infection.

Purpose of the Study:

  • To evaluate the effectiveness of a structured intervention program in improving terminal room cleaning thoroughness in hospital ICUs.
  • To assess the potential of enhanced cleaning to reduce environmental transmission of MDROs.

Main Methods:

  • A prospective, multicenter, pre- and postinterventional study was conducted in 27 acute care hospitals.
  • A fluorescent targeting method objectively assessed terminal room cleaning before and after interventions.
  • Interventions included structured education, procedural changes, and administrative support, with systematic covert monitoring.

Main Results:

  • Baseline cleaning thoroughness of 3532 environmental surfaces in 260 ICU rooms was only 49.5%.
  • Following the intervention, cleaning thoroughness significantly improved to 82%.
  • Improvements were consistent across hospitals of varying sizes and types.

Conclusions:

  • A structured approach, including objective assessment and performance feedback, can substantially improve ICU room cleaning quality.
  • Enhanced environmental hygiene in ICUs presents a key opportunity to improve patient safety and reduce MDRO transmission.
