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.
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.
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.
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.
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.
This cohort study suggests that admission of COVID-19-positive patients into SNFs early in the pandemic was associated with preventable COVID-19 cases and mortality among residents, particularly in facilities with potential staff and PPE shortages. The findings speak to the importance of equipping SNFs to adhere to infection-control best practices as they continue to face COVID-19 strains and other respiratory diseases.
在新冠疫情期间,病情稳定的新冠病毒检测呈阳性患者被转至专业护理机构(SNFs)以缓解医院拥挤状况。由于担心引发疫情,这些转院引发了争议,但几乎没有实证证据可为政策提供参考。
评估新冠病毒检测呈阳性患者入住专业护理机构与该机构随后出现的新冠病例及居民死亡率之间的关联。
设计、背景和参与者:这项队列研究分析了美国疾病控制与预防中心国家医疗安全网络的调查数据。该队列包括2020年6月至2021年3月期间美国的专业护理机构。将有新冠病毒检测呈阳性患者首次入住的机构(即暴露机构)与同一县内且入院前病例数相似、但无新冠病毒检测呈阳性患者首次入住的对照机构进行匹配。数据于2023年6月至2024年2月进行分析。
研究期间首次观察到新冠病毒检测呈阳性患者入住(定义为先前被诊断为新冠病毒感染且仍需采取基于传播的预防措施的患者)的那一周。
首次入住前一周每100名居民中新冠新病例数、新冠相关死亡数及全因死亡数的每周计数。采用叠加差分法比较首次入住前10周和入住后15周的结局。额外分析考察了在工作人员或个人防护装备(PPE)短缺的机构中结局是否有所不同。
确定了一组匹配的264家暴露机构和518家对照机构。在15周的随访期内,与对照专业护理机构相比,暴露的专业护理机构每100名居民中新冠病例累计增加6.94例(95%置信区间为2.91 - 10.98),比样本均值(标准差)22.2(26.4)增加了31.3%。与对照机构相比,暴露机构每100名居民中新冠相关累计死亡数增加2.31例(95%置信区间为1.39 - 3.24),比样本均值(标准差)3.19(5.5)增加了72.4%。与没有此类短缺的机构相比,经历潜在工作人员短缺和个人防护装备短缺的暴露机构每100名居民中新冠病例增加幅度更大(分别额外增加10.97例[95%置信区间为2.76 - 19.19]和14.81例[95%置信区间为2.38 - 27.25])。
这项队列研究表明,在疫情早期将新冠病毒检测呈阳性患者收治到专业护理机构与居民中可预防的新冠病例及死亡率相关,特别是在存在潜在工作人员和个人防护装备短缺的机构中。这些发现表明,在专业护理机构继续面对新冠病毒毒株和其他呼吸道疾病时,配备资源以坚持感染控制最佳实践非常重要。
