Insights

Hospitals can safely reduce isolation for patients previously colonized with methicillin-resistant Staphylococcus aureus (MRSA). Screening patients without recent positive MRSA cultures identified 21% who were no longer colonized and could be removed from contact precautions.

Area of Science:

  • Infectious Diseases
  • Hospital Epidemiology
  • Infection Control

Background:

  • Methicillin-resistant Staphylococcus aureus (MRSA) colonization poses a significant challenge in healthcare settings.
  • Repeated isolation of patients with known MRSA colonization upon hospital readmission can be resource-intensive and impact patient experience.

Purpose of the Study:

  • To evaluate the feasibility and impact of screening patients with a history of MRSA colonization but no recent positive cultures.
  • To reduce unnecessary isolation measures for patients who have cleared MRSA.

Main Methods:

  • A screening protocol was implemented for patients with a history of MRSA colonization.
  • Patients without a positive MRSA culture in the preceding 6 months were tested.
  • Patients found to be non-colonized were removed from contact precautions.

Main Results:

  • Out of 98 screened patients, 21% (21 patients) were no longer colonized with MRSA.
  • These patients were successfully removed from contact precautions, optimizing resource allocation.

Conclusions:

  • Periodic screening can effectively identify patients with resolved MRSA colonization.
  • This approach allows for the de-escalation of isolation precautions, improving hospital workflow and patient care.

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...

Clinical Significance of Antibiotic Resistance

Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within the One...

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 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.

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...
