Abstract

Insights

Topical mupirocin treatment effectively prevents Staphylococcus aureus surgical site infections in nasal carriers. This screen-and-treat strategy is cost-effective when mupirocin resistance remains low.

Area of Science:

  • Infectious Disease
  • Surgical Site Infections
  • Antimicrobial Resistance

Background:

  • Surgical site infections (SSIs) caused by Staphylococcus aureus are a significant concern.
  • Methicillin-resistant Staphylococcus aureus (MRSA) poses a particular challenge in healthcare settings.
  • Preventive strategies are crucial to reduce the burden of these infections.

Purpose of the Study:

  • To review and synthesize literature on preventing Staphylococcus aureus infections in surgical patients.
  • To evaluate the efficacy of different decolonization and prophylaxis methods.
  • To provide perspective on current prevention strategies.

Main Methods:

  • Literature review of studies published between August 2006 and January 2008.
  • Analysis of methods including isolation precautions, antibiotic prophylaxis, and topical decolonization.
  • Evaluation of outcomes related to Staphylococcus aureus and MRSA infections.

Main Results:

  • Topical decolonization with mupirocin reduced Staphylococcus aureus SSIs in nasal carriers.
  • Vancomycin prophylaxis was considered for high-risk MRSA patients.
  • Chlorhexidine gluconate reduced overall nosocomial infections but not specifically S. aureus infections.

Conclusions:

  • Mupirocin treatment of S. aureus carriers is effective in preventing nosocomial SSIs.
  • Screen-and-treat approaches are cost-saving if mupirocin resistance is low.
  • Further research is needed on chlorhexidine's effect on S. aureus carrier rates.

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...
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.
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.

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...
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...
