Abstract

Insights

Nosocomial Methicillin-resistant Staphylococcus aureus (MRSA) infections in intensive care units (ICUs) significantly decreased from 2001 to 2010. Focusing on healthcare-associated infections (HCAI) control is more effective than MRSA-specific measures.

Area of Science:

  • Infectious Diseases
  • Critical Care Medicine
  • Epidemiology

Background:

  • Analysis of German intensive care unit (ICU) data from the national nosocomial infection surveillance system (KISS) over ten years.
  • Observed a rise in Methicillin-resistant Staphylococcus aureus (MRSA) rates from 2001-2005, followed by a slight decrease from 2006-2010.

Purpose of the Study:

  • To investigate the trend in incidence density of nosocomial MRSA infections.
  • To determine the crucial patient outcome indicator for MRSA infections.

Main Methods:

  • Inclusion of data from 103 ICUs with continuous participation.
  • Statistical analysis of incidence density of MRSA infections and healthcare-associated infections (HCAI).

Main Results:

  • A significant decrease in the pooled incidence density of nosocomial MRSA infections from 0.37 to 0.15 per 1000 patient days (2001-2010).
  • This reduction was proportional to a significant decrease in all healthcare-associated infections (HCAI) during the same period.

Conclusions:

  • Emphasizes the importance of general HCAI control measures over MRSA-specific prevention.
  • Suggests that MRSA rates (proportions) are not the most useful indicator for assessing the infection control situation.

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...

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies. Common...

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...
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.

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.
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...
