SNFs: Use the CMS Focused COVID-19 Infection Control Survey Tool to self-assess your IPCP plans.
AHCA/NCAL also have issued guidance: https://www.ahcancal.org/facility_operations/disaster_planning/Pages/Coronavirus.aspx
Be sure, however, to follow CDC and CMS directly, and check in with their website and guidance often. Yesterday, April 2, new guidance was issued, as well as the sobering results of recent CMS surveys that SNFs are not up to par in simple and routine infection control, including handwashing and PPE usage. It also advised to totally separate confirmed or potential COVID cases from other residents by building or unit.
Guidance from the CDC on hand hygiene and PPE usage can be found at the following links:
