Insights

Preventing methicillin-resistant Staphylococcus aureus (MRSA) surgical site infections (SSIs) requires eradicating MRSA nasal carriers before surgery. Treating carriers significantly reduces the risk of postoperative MRSA SSIs, improving patient outcomes.

Area of Science:

  • Infectious Diseases
  • Hospital Epidemiology
  • Surgical Site Infections

Background:

  • Postoperative methicillin-resistant Staphylococcus aureus (MRSA) surgical site infections (SSIs) cause significant morbidity and costs.
  • Previous research highlighted MRSA screening's role in reducing SSI risk.
  • This study quantifies the impact of eradicating MRSA nasal carriage.

Purpose of the Study:

  • To determine the effectiveness of eradicating MRSA nasal carriage in preventing postoperative MRSA SSIs.
  • To analyze the outcomes of universal MRSA screening and carrier state treatment.

Main Methods:

  • Universal MRSA screening via nasal swab and rapid PCR testing for all hospital admissions since February 2007.
  • Treatment of identified MRSA nasal carriers with mupirocin ointment and chlorhexidine soap prior to surgery.
  • Follow-up of patients undergoing Surgical Care Improvement Project (SCIP) procedures for MRSA SSI development (n=8980).

Main Results:

  • Eleven MRSA SSIs (0.12%) occurred among 8980 SCIP procedures.
  • Six of the 11 patients (55%) had negative preoperative MRSA screens.
  • Of five patients with positive screens, only one received carrier state eradication treatment.

Conclusions:

  • Failure to treat MRSA nasal carriage before surgery is linked to MRSA SSI development.
  • Preoperative MRSA screening and targeted carrier eradication are crucial for preventing SSIs.
  • Effective MRSA carrier state management is essential in reducing postoperative infections.

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...
Asepsis01:28

Asepsis

The condition of being free from disease-causing living pathogens is asepsis. Aseptic techniques include a set of standard practices to achieve asepsis. An example is the regular environmental cleaning of all parts of the healthcare facility and hand hygiene at home before preparing or eating food. Medical and surgical asepsis in healthcare practice protects patients from harmful pathogens, minimizes the risk of contamination of susceptible sites, and reduces the risk of infection transmission.

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.
