Importance: Skilled nursing facilities (SNFs) experienced high mortality during the COVID-19 pandemic, leading them to adopt preventive measures to counteract viral spread. A critical appraisal of these measures is essential to support SNFs in managing future infectious disease outbreaks.
Objective: To perform a scoping review of data and evidence on the use and effectiveness of preventive measures implemented from 2020 to 2024 to prevent COVID-19 infection in SNFs in the US.
Evidence review: Two analyses were performed. First, an analysis of the federal COVID-19 SNF Database was conducted to describe time trends in COVID-19 incidence, deaths, testing, vaccination, and treatment among SNF residents and staff, as well as shortages in staff and personal protective equipment (PPE). Then, a comprehensive literature search was conducted from May 2023 to April 2024 to identify high-quality evidence on the use and effectiveness of modifiable preventive measures used among SNF residents. Both nonpharmacologic (facility characteristics, PPE, cohorting, and isolation, visitation, staffing, testing) and pharmacologic (vaccination, treatment) measures were reviewed.
Findings: Nationwide data indicated early shortages of PPE, infrequent testing, and persistent staff shortages in SNFs. Other nonpharmacologic measures, such as visitor restrictions or ventilation modifications, were widely adopted but there were no available national data to quantify their effectiveness. These nonpharmacologic measures lacked high-quality studies to verify effectiveness. In contrast, the effectiveness of vaccination and antiviral treatment was shown in multiple studies. Evidence also showed associations between COVID-19 outcomes in residents and crowding, staff size, hours per residents and networks, and surveillance testing of residents and staff. Despite high initial uptake, up-to-date vaccination status was suboptimal in residents and staff from 2022 to 2024. Only a minority of infected residents received antiviral treatment.
Conclusions and relevance: This scoping review found that although many preventive measures were implemented in SNFs in the US throughout the COVID-19 pandemic, few were based on clear evidence of their effectiveness. Pharmacologic measures, such as vaccination and antiviral treatment, had more robust evidence supporting their efficacy than nonpharmacologic interventions. Using the scarce resources and staff of SNFs on measures of questionable effectiveness could distract from known effective ones such as vaccination and antiviral treatment. When possible, implementation efforts should be commensurate with the demonstrated effectiveness of available preventive measures.
