Hospital affiliated long term care facility COVID-19 containment strategy by using prevalence testing and infection control best practices.

• Long term care facility used serial point prevalence testing for SARS-CoV-2 on all residents and employees every 2 weeks to contain an outbreak. • Infection control best practices were put into place using multidisciplinary strike team approach that encompassed acute care physicians, leadership, engineering, and emergency medicine partners. • Cohort unit was established to isolate all exposed and new admissions to facility for 14 days in order to contain spread. In a hospital affiliated long term care facility, we found an opportunity to interrupt a potential outbreak of COVID-19 using a point prevalence testing containment strategy and applying infection prevention and control best practices. Three serial point prevalence studies were conducted on all residents and employees in 14-day intervals and percent positive was used as marker for effective infection control efforts. A multidisciplinary strike team from acute care was used to disseminate infection control education and support to long term care partners. These results highlight the need for swift identification and action in congregant high risk settings to prevent rapid spread and large scale outbreaks of COVID-19.
