Multidrug-resistant organisms in a community living facility: tracking patient interactions and time spent in common...

Area of Science:

• Infection Control
• Public Health
• Healthcare Epidemiology

Background:

• Contact precautions are standard in community living facilities (CLF) to limit multidrug-resistant organism (MDRO) transmission.
• Current policies may not fully address environmental and social transmission routes in CLF settings.
• Shared spaces and devices pose risks for MDRO spread among residents.

Purpose of the Study:

• To investigate the extent of interactions between multidrug-resistant organism (MDRO)-positive patients and others in communal areas.
• To identify potential gaps in current contact precaution strategies within community living facilities.
• To provide data for refining infection control policies in CLF.

Main Methods:

• Utilized a real-time surveillance system to monitor patient movements and interactions.
• Focused on community living facility residents identified as positive for multidrug-resistant organisms.
• Quantified the time spent by MDRO-positive individuals in communal areas with others.

Main Results:

• MDRO-positive patients engage in significant interactions within communal areas.
• Real-time data reveals specific high-risk periods and locations for potential MDRO transmission.
• Current contact precaution measures may be insufficient to prevent transmission in shared environments.

Conclusions:

• Contact precautions in CLF require enhancement to cover shared spaces and resident interactions.
• Real-time surveillance offers valuable insights for optimizing infection control strategies.
• Tailored MDRO policies are essential for improving resident safety in community living facilities.
