Hospitalizations among skilled nursing facility (SNF) residents in Detroit increased in mid-March 2020 due to the coronavirus disease 2019 (COVID-19) pandemic. Outbreak response teams were deployed from local healthcare systems, the Centers for Disease Control and Prevention (CDC), and the Detroit Health Department (DHD) to understand the infection prevention and control (IPC) gaps in SNFs that may have accelerated the outbreak.
We conducted 2 point-prevalence surveys (PPS-1 and PPS-2) at 13 Detroit SNFs from April 8 to May 8, 2020. The DHD and partners conducted facility-wide severe acute respiratory coronavirus virus 2 (SARS-CoV-2) testing of all residents and staff and collected information regarding resident cohorting, staff cohorting, and personnel protective equipment (PPE) utilized during that time.
Resident cohorting had been implemented in 7 of 13 (58.3%) SNFs prior to point-prevalence survey 1 (PPS-1), and other facilities initiated cohorting after obtaining PPS-1 results. Cohorting protocols of healthcare practitioners and environmental service staff were not established in 4 (31%) of 13 facilities, and in 3 facilities (23.1%) the ancillary staff were not assigned to cohorts. Also, 2 SNFs (15%) had an observation unit prior to PPS-1, 2 (15%) had an observation unit after PPS-1, 4 (31%) could not establish an observation unit due to inadequate space, and 5 (38.4%) created an observation unit after PPS-2.
On-site consultations identified gaps in IPC knowledge and cohorting that may have contributed to ongoing transmission of SARS-CoV-2 among SNF residents despite aggressive testing measures. Infection preventionists (IPs) are critical in guiding ongoing IPC practices in SNFs to reduce spread of COVID-19 through response and prevention.
由于 2019 年冠状病毒病(COVID-19)大流行,底特律熟练护理机构(SNF)居民的住院人数在 2020 年 3 月中旬增加。当地医疗系统、疾病控制与预防中心(CDC)和底特律卫生部(DHD)部署了疫情应对小组,以了解可能加速疫情爆发的 SNF 感染预防和控制(IPC)差距。
我们于 2020 年 4 月 8 日至 5 月 8 日在底特律的 13 个 SNF 进行了 2 次时点患病率调查(PPS-1 和 PPS-2)。DHD 和合作伙伴对所有居民和工作人员进行了全面的严重急性呼吸系统冠状病毒 2(SARS-CoV-2)检测,并收集了在此期间居民分组、工作人员分组和人员防护设备(PPE)使用的信息。
在进行第一次时点患病率调查(PPS-1)之前,有 7 个 SNF(58.3%)实施了居民分组,其他设施在获得 PPS-1 结果后开始分组。在 13 个设施中,有 4 个设施(31%)未制定医护人员和环境服务人员的分组方案,有 3 个设施(23.1%)未将辅助人员分配到分组中。此外,在 PPS-1 之前,有 2 个 SNF(15%)设有观察单元,在 PPS-1 之后,有 2 个 SNF(15%)设有观察单元,有 4 个 SNF(31%)由于空间不足无法设立观察单元,在 PPS-2 之后,有 5 个 SNF(38.4%)设立了观察单元。
现场咨询发现,IPC 知识和分组方面存在差距,这可能导致尽管采取了积极的检测措施,但 SNF 居民中的 SARS-CoV-2 仍在持续传播。感染预防专家(IPs)在指导 SNF 持续的 IPC 实践方面至关重要,以减少 COVID-19 通过应对和预防措施的传播。
