[Antimicrobial Stewardship and Hygiene: Prevention of Multidrug Resistant Pathogens]
Abstract:
The increasing prevalence of multidrug-resistant organisms (MDRO) poses a major threat to healthcare systems. Critically ill patients are at heightened risk to acquire MDRO infections resulting in longer hospital stays and higher mortality rates. This article provides an overview of preventive measures, divided into Infection Prevention and Control (IPC) and Antimicrobial Stewardship (AMS) approaches. IPC measures focus on the prevention of MDRO spread by applying basic and extended hygiene strategies. While basic hygiene such as hand and surface disinfection are effective in stopping any pathogen transmission, extended hygiene strategies including screening approaches, patient isolation and contact precautions are essential to identify MDRO patients and separate them from other susceptible patients. On the one hand, AMS aims at reducing the development of resistances under selective pressure by rational use of antimicrobials. On the other hand, interdisciplinary AMS-teams provide recommendations to optimize targeted MDRO therapy, including the rational use of "new" antibiotics. By pursuing different starting points, both IPC- and AMS-strategies are necessary in the prevention of MDRO development and transmission.
Insights
Preventing multidrug-resistant organism (MDRO) infections in critically ill patients requires both Infection Prevention and Control (IPC) and Antimicrobial Stewardship (AMS) strategies. These approaches reduce MDRO spread and the development of antimicrobial resistance.
Area of Science:
- Healthcare-associated infections
- Infectious disease epidemiology
- Public health
Background:
- Multidrug-resistant organisms (MDRO) present a significant and growing threat to healthcare systems globally.
- Critically ill patients are particularly vulnerable to MDRO infections, leading to prolonged hospitalizations and increased mortality.
- Effective strategies are crucial to mitigate the impact of MDROs on patient outcomes and healthcare costs.
Purpose of the Study:
- To provide a comprehensive overview of preventive measures against multidrug-resistant organisms (MDRO).
- To delineate the distinct yet complementary roles of Infection Prevention and Control (IPC) and Antimicrobial Stewardship (AMS) in combating MDROs.
- To highlight the necessity of integrating both IPC and AMS for comprehensive MDRO prevention.
Main Methods:
- Review of current Infection Prevention and Control (IPC) strategies, including basic and extended hygiene measures.
- Examination of Antimicrobial Stewardship (AMS) approaches focused on rational antimicrobial use and resistance development.
- Analysis of the combined efficacy of IPC and AMS in preventing MDRO development and transmission.
Main Results:
- Basic hygiene (e.g., hand disinfection) and extended hygiene (e.g., screening, isolation) are vital for preventing MDRO spread.
- Antimicrobial Stewardship (AMS) reduces resistance by optimizing antimicrobial use and guiding therapy for MDRO infections.
- Both IPC and AMS strategies are independently effective but essential when implemented together.
Conclusions:
- A dual approach combining Infection Prevention and Control (IPC) and Antimicrobial Stewardship (AMS) is necessary for effective prevention of multidrug-resistant organisms (MDRO).
- IPC measures control transmission, while AMS strategies curb resistance development and optimize treatment.
- Integrated strategies are paramount to combat the increasing threat of MDROs in healthcare settings.
