Effectiveness of an infection prevention strategy to limit exposure of high-risk patients to COVID-19 in a hospital-based subacute unit: a descriptive report

The coronavirus (COVID-19) epidemic has put unprecedented stress on hospitals as well as skilled nursing facilities, where reside some of the most vulnerable individuals at high risk of mortality and complications of this infection. This report highlights the strategy and success of hospital infection prevention efforts to protect the residents of an in-hospital subacute unit with 24 at-risk patients with chronic pulmonary disease in northern California. Specific efforts are detailed, with results of surveillance testing reported, including both viral PCR and serological IgG assays. Implications for other long-term subacute care facilities are discussed, as well as advantages and specific challenges for ‘distinct part’ versus ‘free-standing’ subacute care units.
