Insights

Identifying patients at high risk for methicillin-resistant Staphylococcus aureus (MRSA) nasal carriage is crucial. Nursing home residents and patients transferred from other hospitals are significantly more likely to carry MRSA upon admission.

Area of Science:

  • Infectious Diseases
  • Clinical Microbiology
  • Epidemiology

Background:

  • Nasal carriage of methicillin-resistant Staphylococcus aureus (MRSA) is a significant concern in healthcare settings.
  • Identifying high-risk patient populations upon hospital admission is essential for infection control.

Purpose of the Study:

  • To identify specific patient demographics and conditions associated with an increased risk of MRSA nasal carriage at the time of hospital admission.

Main Methods:

  • A prospective study involving nasal swabs from 136 admitted patients between March and July 2000.
  • Patients were categorized by age (>=70), ambulatory status, nursing home residency, prior hospital admission, and pre-surgical status.
  • Multivariate analysis was employed to determine risk factors for MRSA nasal carriage.

Main Results:

  • MRSA was detected in 8.8% (12/136) of the enrolled patients.
  • Living in a nursing home (OR=32.82) and transfer from another hospital (OR=14.55) were identified as significant risk factors.
  • Advanced age (>=80 or >=90 years) also emerged as an independent high-risk factor (OR=3.08).

Conclusions:

  • Nursing home residency, transfer from another hospital, and advanced age are key indicators of high risk for MRSA nasal carriage in admitted patients.
  • These findings can inform targeted screening and decolonization strategies to reduce MRSA transmission in hospitals.

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 the One...
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 acquisition...
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...
Microbiota of the Respiratory Tract01:29

Microbiota of the Respiratory Tract

The human respiratory tract, comprising the upper and lower segments, serves as a critical interface with the external environment. The upper respiratory tract (URT)—including the nostrils, sinuses, pharynx, and oropharynx—is heavily colonized by microbes, while the lower respiratory tract (LRT), composed of the larynx, trachea, bronchi, and lungs, was long thought to be sterile. However, recent molecular studies have revealed that the lungs are not devoid of microbes but act more like...

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...

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...
