Three-Tiered COVID-19 Cohorting Strategy and Implications for Memory-Care.

Area of Science:

• Infectious Disease Epidemiology
• Public Health Management
• Geriatric Care

Background:

• Skilled nursing facilities (SNFs) are highly vulnerable to devastating SARS-CoV-2 outbreaks.
• Challenges include identifying asymptomatic/presymptomatic cases and limited early treatment/vaccination options.
• Effective outbreak mitigation strategies are crucial for resident and staff safety.

Purpose of the Study:

• To present a guide for rapid deployment of point-prevalence testing in SNFs.
• To outline a 3-tiered cohorting strategy to mitigate SARS-CoV-2 outbreaks.
• To identify and discuss key challenges associated with SNF cohorting.

Main Methods:

• Development and implementation of a rapid point-prevalence testing protocol.
• Establishment of a 3-tiered cohorting system based on testing results and exposure status.
• Analysis of practical challenges encountered during implementation.

Main Results:

• A structured approach for swift outbreak detection through point-prevalence testing.
• A cohorting framework designed to limit viral transmission within the SNF.
• Identification of critical factors influencing successful cohorting implementation.

Conclusions:

• Rapid testing and strategic cohorting are vital for controlling SARS-CoV-2 outbreaks in SNFs.
• Proactive planning and addressing implementation challenges are key to successful mitigation.
• This guide provides a practical framework for SNFs facing infectious disease emergencies.
