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...
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 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...
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 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...
Infection01:20

Infection

When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Summary

Multidrug-resistant organism (MDRO) history is a common reason for enhanced barrier precautions (EBP) in nursing homes. However, MDRO history poorly identifies current colonization, suggesting it may not be an effective EBP indication.

Area of Science:

  • Infection Control
  • Epidemiology
  • Healthcare-Associated Infections

Background:

  • Nursing home residents frequently harbor multidrug-resistant organisms (MDROs).
  • Enhanced barrier precautions (EBP) are recommended for residents with specific MDROs, devices, or wounds.
  • Facilities can extend EBP to other residents as needed.

Purpose of the Study:

  • To evaluate the effectiveness of current Enhanced Barrier Precautions (EBP) indications for identifying multidrug-resistant organism (MDRO) colonization in nursing home residents.
  • To assess the prevalence of MDRO colonization based on clinical characteristics and surveillance cultures.

Main Methods:

  • Prospective admission surveillance cultures were collected from anterior nares and inguinal skin in 4 Maryland nursing homes.
  • Clinical characteristics, including MDRO history, medical devices, and chronic wounds, were recorded for 580 short-stay residents.
  • MDRO colonization prevalence was estimated using culture results.

Main Results:

  • 21% of residents were found to be colonized with MDROs.
  • MDRO history was present in 21% of residents, medical devices in 13%, and chronic wounds in 9%.
  • Only 25% of residents with an MDRO history were culture-positive for MDROs, and vice versa, indicating poor predictive value.

Conclusions:

  • MDRO history is the most frequent reason for EBP in short-stay nursing home residents.
  • Novel or targeted MDROs were uncommon.
  • MDRO history is an unreliable indicator for implementing EBP as it poorly identifies current MDRO colonization.
