Since its emergence in late 2019, SARS-CoV-2 continues to pose a risk to healthcare personnel (HCP) and patients in healthcare settings. Although all clinical interactions likely carry some risk of transmission, human actions like coughing and care activities like aerosol-generating procedures likely have a higher risk of transmission. The rapid emergence and global spread of SARS-CoV-2 continues to create significant challenges in healthcare facilities, particularly with shortages of personal protective equipment (PPE) used by HCP. Evidence-based recommendations for what PPE to use in conventional, contingency, and crisis standards of care continue to be needed. Where evidence is lacking, the development of specific research questions can help direct funders and investigators.
Develop evidence-based rapid guidelines intended to support HCP in their decisions about infection prevention when caring for patients with suspected or known COVID-19.
IDSA formed a multidisciplinary guideline panel including frontline clinicians, infectious disease specialists, experts in infection control, and guideline methodologists with representation from the disciplines of public health, medical microbiology, pediatrics, critical care medicine and gastroenterology. The process followed a rapid recommendation checklist. The panel prioritized questions and outcomes. Then a systematic review of the peer-reviewed and grey literature was conducted. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to assess the certainty of evidence and make recommendations.
The IDSA guideline panel agreed on eight recommendations, including two updated recommendations and one new recommendation added since the first version of the guideline. Narrative summaries of other interventions undergoing evaluations are also included.
Using a combination of direct and indirect evidence, the panel was able to provide recommendations for eight specific questions on the use of PPE for HCP providing care for patients with suspected or known COVID-19. Where evidence was lacking, attempts were made to provide potential avenues for investigation. There remain significant gaps in the understanding of the transmission dynamics of SARS-CoV-2 and PPE recommendations may need to be modified in response to new evidence. These recommendations should serve as a minimum for PPE use in healthcare facilities and do not preclude decisions based on local risk assessments or requirements of local health jurisdictions or other regulatory bodies.
自2019年末出现以来,严重急性呼吸综合征冠状病毒2(SARS-CoV-2)持续对医疗机构中的医护人员(HCP)和患者构成风险。尽管所有临床互动都可能存在一定的传播风险,但诸如咳嗽等人类行为以及诸如产生气溶胶的操作等护理活动可能具有更高的传播风险。SARS-CoV-2的迅速出现和全球传播继续给医疗机构带来重大挑战,尤其是医护人员使用的个人防护装备(PPE)短缺。仍然需要针对常规、应急和危机护理标准中使用何种个人防护装备的循证建议。在缺乏证据的情况下,制定具体的研究问题有助于指导资助者和研究者。
制定循证快速指南,旨在支持医护人员在护理疑似或确诊新型冠状病毒肺炎(COVID-19)患者时做出感染预防决策。
美国感染病学会(IDSA)组建了一个多学科指南小组,成员包括一线临床医生、传染病专家、感染控制专家以及来自公共卫生、医学微生物学、儿科学、重症医学和胃肠病学等学科的指南方法学家。该过程遵循快速推荐清单。小组对问题和结果进行了优先排序。然后对同行评审文献和灰色文献进行了系统评价。采用推荐分级评估、制定与评价(GRADE)方法评估证据的确定性并提出建议。
IDSA指南小组就八项建议达成一致,包括自指南第一版以来的两项更新建议和一项新建议。还包括正在接受评估的其他干预措施的叙述性总结。
通过结合直接和间接证据,小组能够就医护人员在护理疑似或确诊COVID-19患者时使用个人防护装备的八个具体问题提供建议。在缺乏证据的情况下,尝试提供潜在的调查途径。在严重急性呼吸综合征冠状病毒2传播动态的理解方面仍然存在重大差距,个人防护装备建议可能需要根据新证据进行修改。这些建议应作为医疗机构中个人防护装备使用的最低标准,并不排除基于当地风险评估或当地卫生辖区或其他监管机构要求所做的决策。
