ensure they would be applicable in both high-and low-resource settings. Secondly, while remaining intensive care unit (ICU)-focused, the 2021 Guidelines acknowledged the long-term impact of sepsis, including physical, psychological, and mental problems experienced by sepsis survivors and their families. A new section of the Guidelines was developed to address long-term outcomes and goals of care in sepsis, with an expanded patient and public involvement in the panel to provide input on the Guidelines and ensure they were consistent with patient and family needs, values, and preferences for care.In this paper, we outline the noteworthy aspects of each section of the 2021 Guidelines that represent a change from previous practice, address an important clinical question not previously discussed, or remain an area of persistent clinical challenge. Of note, we do not address issues related to the COVID-19 pandemic, Introduction Despite advances in rapid recognition and resuscitation, sepsis remains a major cause of morbidity and mortality worldwide, underscoring the need for continued research, education, and knowledge translation activities. 1,2 Since its inception in 2002, the Surviving Sepsis Campaign (SSC) has played a central role in improving the care of patients with sepsis. As a collaboration between the Society of Critical Care Medicine and the European Society of Intensive Care Medicine, with endorsement from many other national and international societies, the SSC Guidelines represent the currently accepted standard for sepsis care in adults. 3 The 2021 Guidelines build upon and advance the earlier versions in important ways. Firstly, they address sepsis as a global health threat. To this end, the leadership explicitly sought to increase diversity in the representative panelists as well as the recommendations themselves to
