A comprehensive, evidence-based clinical guideline for the screening, early recognition, resuscitation, hemodynamic management, antimicrobial therapy, and organ support in adult patients with sepsis and septic shock. This resource synthesizes recommendations from the major international critical care professional societies, surviving sepsis working groups, infectious disease expert panels, and regulatory quality measures into a single integrated reference for intensivists, emergency physicians, hospitalists, and advanced practice providers who manage critically ill patients with suspected or confirmed sepsis.1 2 3 4 5 6

Sepsis remains a leading cause of death worldwide, with an estimated 48.9 million cases and 11.0 million sepsis-related deaths annually — representing nearly 20% of all global deaths. Hospital mortality in septic shock ranges from 30% to 50% depending on illness severity, comorbidities, and timeliness of intervention. The cornerstones of sepsis management — early recognition, rapid antimicrobial administration, appropriate fluid resuscitation, timely vasopressor initiation, and source control — are supported by strong evidence and form the basis of the hour-1 resuscitation bundle endorsed by the international critical care consensus.

Frequently asked questions

What is sepsis?
Sepsis is life-threatening organ dysfunction caused by a dysregulated host response to infection (the Sepsis-3 definition). It is identified clinically by infection plus evidence of organ dysfunction, often screened with a rise in the SOFA score or with qSOFA at the bedside.
What is the difference between sepsis and septic shock?
Septic shock is a subset of sepsis with circulatory and metabolic abnormalities severe enough to substantially increase mortality. Clinically it is sepsis with persistent hypotension requiring vasopressors to keep the mean arterial pressure at or above 65 mmHg and a serum lactate above 2 mmol/L despite adequate fluid resuscitation.
What is the sepsis bundle?
The Surviving Sepsis Campaign Hour-1 bundle is the set of actions started as soon as sepsis is recognized: measure lactate, obtain blood cultures before antibiotics, give broad-spectrum antibiotics, begin rapid crystalloid (30 mL/kg) for hypotension or a lactate of 4 mmol/L or higher, and start vasopressors if hypotension persists during or after fluids to maintain a MAP of at least 65 mmHg.
