Abstract

Insights

Contact precautions (CPs) may reduce methicillin-resistant Staphylococcus aureus (MRSA) transmission in some settings, but evidence for routine use is limited. CPs can also lead to negative patient experiences and reduced healthcare provider interaction.

Area of Science:

  • Infectious Disease Epidemiology
  • Healthcare Infection Control
  • Patient Safety

Background:

  • Contact precautions (CPs) are standard for preventing methicillin-resistant Staphylococcus aureus (MRSA) spread in healthcare.
  • Concerns exist regarding CP effectiveness and their negative impact on patient care and experiences.
  • This study aimed to assess the efficacy and adverse outcomes of CPs for MRSA prevention.

Purpose of the Study:

  • To evaluate the effectiveness of contact precautions in preventing MRSA transmission.
  • To identify and analyze adverse outcomes associated with contact precautions.
  • To inform recommendations on the appropriate use of CPs for MRSA.

Main Methods:

  • Systematic literature search of PubMed, Embase, and Cochrane Library.
  • Inclusion of studies from US acute care settings with control groups or standardized data.
  • Synthesis and examination of findings for limitations to guide recommendations.

Main Results:

  • CPs demonstrated effectiveness in reducing MRSA transmission during outbreaks and with high compliance.
  • No significant decrease in overall MRSA infection rates was observed.
  • Adverse outcomes included reduced healthcare provider-patient time, low compliance, decreased patient comfort, and increased patient complaints.

Conclusions:

  • Limited data support routine use of CPs for MRSA control in endemic settings.
  • Hospital education should focus on improving patient perception of care and understanding of CPs.
  • Enhancing healthcare provider adherence to hand hygiene and standard precautions is crucial.

Clinical Significance of Antibiotic Resistance01:25

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...

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...

Staphylococcal Skin Infections01:29

Staphylococcal Skin Infections

Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...

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...

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.

Mechanism of Antibiotic Resistance in MRSA01:25

Mechanism of Antibiotic Resistance in MRSA

Antibiotic resistance in bacteria arises when microorganisms evolve the ability to withstand drugs designed to kill them or inhibit their growth, rendering once-effective treatments useless. This phenomenon, driven by genetic change and selection under antibiotic exposure, poses a profound threat to modern medicine. Mechanisms include drug-inactivating enzymes (e.g., β-lactamases), efflux pumps that eject antibiotics, mutations altering antibiotic targets, decreased drug uptake, and...
