[Control of multiple-resistant bacteria]
1Unité d'hygiène et de lutte contre les infections nosocomiales Groupe hospitalier Bichat-Claude Bernard, Paris.
Abstract:
The number of multiply-resistant bacteria, especially methicillin-resistant Staphyloccoccus aureus, has reached an alarming level in France. This number reflects the inadequacy of efforts against nosocomial infections, and non-respect of hygiene rules by hospital staff. Two mechanisms lead to multiple resistance: the selection of multiply-resistant bacteria by antimicrobials; and, once resistance is acquired, bacterial dissemination by hand-mediated cross transmission. Controlling the spread of multiple resistance thus requires both judicious use of antimicrobials, and compliance with basic rules of hygiene, particularly handwashing. Although the hospital setting favors the emergence and spread of bacterial resistance, this is also increasing, albeit to a lesser extent, in the non-hospital environment. The same measures of careful antimicrobial use and good hygiene should be applied.
Insights
Multiply-resistant bacteria, like methicillin-resistant Staphylococcus aureus (MRSA), are increasing in France due to inadequate infection control and poor hygiene. Combating this requires careful antimicrobial use and strict adherence to handwashing protocols in hospitals and beyond.
Area of Science:
- Microbiology
- Infectious Diseases
- Public Health
Background:
- Alarming rise in multiply-resistant bacteria, particularly methicillin-resistant Staphylococcus aureus (MRSA), observed in France.
- Identified inadequacy in nosocomial infection control and non-adherence to hygiene rules by hospital staff as contributing factors.
Purpose of the Study:
- To investigate the mechanisms driving the spread of multiply-resistant bacteria.
- To emphasize the importance of antimicrobial stewardship and hygiene in controlling bacterial resistance.
Main Methods:
- Analysis of resistance mechanisms: antimicrobial selection and hand-mediated cross-transmission.
- Evaluation of current infection control practices in healthcare settings.
Main Results:
- Two primary mechanisms identified: selection of resistant strains by antimicrobials and dissemination via cross-transmission.
- Hospital environment identified as a key setting for resistance emergence and spread, with increasing rates also noted in non-hospital environments.
Conclusions:
- Controlling the spread of multiply-resistant bacteria necessitates judicious antimicrobial use and strict compliance with hygiene standards, especially handwashing.
- Recommended measures applicable to both hospital and non-hospital settings to mitigate the growing threat of antibiotic resistance.
