Clinical Outcomes After Admission of Patients With COVID-19 to Skilled Nursing Facilities

IMPORTANCE: During the COVID-19 pandemic, stabilized COVID-19–positive patients were discharged to skilled nursing facilities (SNFs) to alleviate hospital crowding. These discharges generated controversy due to fears of seeding outbreaks, but there is little empirical evidence to inform policy. OBJECTIVE: To assess the association between the admission to SNFs of COVID-19–positive patients and subsequent COVID-19 cases and death rates among residents. DESIGN, SETTING, AND PARTICIPANTS: This cohort study analyzed survey data from the National Healthcare Safety Network of the Centers for Disease Control and Prevention. The cohort included SNFs in the US from June 2020 to March 2021. Exposed facilities (ie, with initial admission of COVID-19–positive patients) were matched to control facilities (ie, without initial admission of COVID-19–positive patients) in the same county and with similar preadmission case counts. Data were analyzed from June 2023 to February 2024. EXPOSURE: The week of the first observable admission of COVID-19–positive patients (defined as those previously diagnosed with COVID-19 and continued to require transmission-based precautions) during the study period. MAIN OUTCOMES AND MEASURES: Weekly counts of new cases of COVID-19, COVID-19–related deaths, and all-cause deaths per 100 residents in the week prior to the initial admission. A stacked difference-in-differences approach was used to compare outcomes for 10 weeks before and 15 weeks after the first admission. Additional analyses examined whether outcomes differed in facilities with staff or personal protective equipment (PPE) shortages. RESULTS: A matched group of 264 exposed facilities and 518 control facilities was identified. Over the 15-week follow-up period, exposed SNFs had a cumulative increase of 6.94 (95% CI, 2.91-10.98) additional COVID-19 cases per 100 residents compared with control SNFs, a 31.3% increase compared with the sample mean (SD) of 22.2 (26.4). Exposed facilities experienced 2.31 (95% CI, 1.39-3.24) additional cumulative COVID-19–related deaths per 100 residents compared with control facilities, representing a 72.4% increase compared with the sample mean (SD) of 3.19 (5.5). Exposed facilities experiencing potential staff shortage and PPE shortage had larger increases in COVID-19 cases per 100 residents (additional 10.97 [95% CI, 2.76-19.19] cases and additional 14.81 [95% CI, 2.38-27.25] cases, respectively) compared with those without such shortages.
