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

J Am Med Dir Assoc. 2020 Nov;21(11):1560-1562. doi: 10.1016/j.jamda.2020.09.001. Epub 2020 Sep 6.


An outbreak of SARS-CoV-2 in a skilled nursing facility (SNF) can be devastating for residents and staff. Difficulty identifying asymptomatic and presymptomatic cases and lack of vaccination or treatment options make management challenging. We created, implemented, and now present a guide to rapidly deploy point-prevalence testing and 3-tiered cohorting in an SNF to mitigate an outbreak. We outline key challenges to SNF cohorting.

Keywords: COVID-19; Cohorting; SARS-CoV-2; asymptomatic carriers; long-term care; point prevalence.
