During the current COVID-19 pandemic, health-care workers and uninfected patients in intensive care units (ICUs) are at risk of being infected with SARS-CoV-2 as a result of transmission from infected patients and health-care workers. In the absence of high-quality evidence on the transmission of SARS-CoV-2, clinical practice of infection control and prevention in ICUs varies widely. Using a Delphi process, international experts in intensive care, infectious diseases, and infection control developed consensus statements on infection control for SARS-CoV-2 in an ICU. Consensus was achieved for 31 (94%) of 33 statements, from which 25 clinical practice statements were issued. These statements include guidance on ICU design and engineering, health-care worker safety, visiting policy, personal protective equipment, patients and procedures, disinfection, and sterilisation. Consensus was not reached on optimal return to work criteria for health-care workers who were infected with SARS-CoV-2 or the acceptable disinfection strategy for heat-sensitive instruments used for airway management of patients with SARS-CoV-2 infection. Well designed studies are needed to assess the effects of these practice statements and address the remaining uncertainties.

在当前的 COVID-19 大流行期间，重症监护病房 (ICU) 中的医护人员和未受感染的患者由于受感染患者和医护人员的传播而面临感染 SARS-CoV-2 的风险。由于缺乏关于 SARS-CoV-2 传播的高质量证据，ICU 感染控制和预防的临床实践差异很大。使用德尔菲法，重症监护、传染病和感染控制方面的国际专家制定了关于 ICU 中 SARS-CoV-2 感染控制的共识声明。33 份声明中的 31 份 (94%) 达成了共识，其中发布了 25 份临床实践声明。这些声明包括有关 ICU 设计和工程、医护人员安全、探视政策、个人防护设备、患者和程序的指南，消毒、灭菌。对于感染 SARS-CoV-2 的医护人员的最佳重返工作标准或用于 SARS-CoV-2 感染患者气道管理的热敏器械的可接受消毒策略，尚未达成共识。需要精心设计的研究来评估这些实践声明的影响并解决剩余的不确定性。
