| Change | 2026 Recommendations | Strength of recommendation/certainty of evidence | 2021 Recommendations |
|---|---|---|---|
| New | For hospitals and health systems, we “suggest” using a “code sepsis” or “sepsis huddle” protocol over not using such a protocol. | Conditional/⊕⊕○○ | |
| ⁕Remarks: | |||
| “Code sepsis” or “sepsis huddle” protocols involve a multidisciplinary team huddle at bedside to discuss and expedite sepsis diagnosis and treatment following a positive sepsis screen. | |||
| New | In acutely ill adults en route to hospital by ambulance or flight, we “suggest” using a standard sepsis screening tool over not using a screening tool. | Conditional/⊕○○○ | - |
| Revisited | For adults with sepsis-induced hypoperfusion or septic shock, we “suggest” administering at least 30 mL/kg of IV crystalloid in the first 3 hours. | Conditional/⊕⊕○○ | For patients with sepsis induced hypoperfusion or septic shock we suggest that at least 30 mL/kg of IV crystalloid fluid should be given within the first 3 hours of resuscitation. |
| ⁕Remarks: | |||
| Consideration should be given to individual patient characteristics and context when selecting initial fluid volume. | |||
| Clinicians prescribing fluids should perform frequent, ongoing reassessment and closely monitor patients to avoid harms of under- or over-resuscitation. | |||
| Weight-based fluid volume should be calculated based on actual body weight, or by adjusted or ideal body weight in patients with body mass index > 30 kg/m2. | |||
| New | For adults with sepsis-induced hypotension, we “suggest” initial IV crystalloid fluid bolus resuscitation followed by vasopressor support if hypotension persists. | Conditional/⊕○○○ | - |
| ⁕Remarks: | |||
| In patients with unstable septic shock, immediate concurrent administration of vasopressors together with IV crystalloid fluid may be warranted on a case-by-case basis. Presence of unstable shock should be determined by physical examination. Suggestive clinical features of unstable shock include severely reduced blood pressure, mottled skin, ashen appearance, cyanosis/decreased oxygen saturation, tachycardia, and altered mentation. | |||
| Revisited | In adults with septic shock, we “suggest” starting vasopressors peripherally to restore MAP rather than delaying initiation until central venous access is secured. | Conditional/⊕○○○ | For adults with septic shock, we suggest starting vasopressors peripherally to restore MAP rather than delaying initiation until a central venous access is secured. |
| ⁕Remarks: | ⁕Remarks: | ||
| Data are insufficient to recommend a duration of use, dose, or access route (size of peripheral IV line or anatomic location). Midline catheters were not considered. | When using vasopressors peripherally, they should be administered only for a short period of time and in a vein in or proximal to the antecubital fossa. | ||
| New | For adults with septic shock 65 years old or older, we “suggest” an initial MAP range of 60–65 mm Hg over higher ranges. | Conditional/⊕⊕○○ | For adults with septic shock on vasopressors, we recommend an initial target MAP of 65 mm Hg over higher MAP targets. |
| Revisited | For adults with possible, probable, or definite septic shock, we “recommend” administering antimicrobial therapy immediately, ideally within 1 hour of recognition. | Strong/⊕○○○ | For adults with possible septic shock or a high likelihood for sepsis, we recommend administering antimicrobials immediately, ideally within 1 hour of recognition. |
| Revisited | For adults with probable or definite sepsis without shock, we “recommend” administering antimicrobial therapy immediately, ideally within 1 hour of recognition. | Strong/⊕○○○ | For adults with possible sepsis without shock, we recommend rapid assessment of the likelihood of infectious versus noninfectious causes of acute illness. |
| ⁕Remarks: | |||
| Rapid assessment includes history and clinical examination, tests for both infectious and noninfectious causes of acute illness and immediate treatment for acute conditions that can mimic sepsis. Whenever possible this should be completed within 3 hours of presentation so that a decision can be made as to the likelihood of an infectious cause of the patient’s presentation and timely antimicrobial therapy provided if the likelihood of sepsis is thought to be high. | |||
| Revisited | For adults with possible sepsis without shock, we “suggest” a time-limited course of rapid investigation and if concern for infection persists, the administration of antimicrobial therapy within 3 hours from the time when sepsis was first suspected. | Conditional/⊕○○○ | For adults with possible sepsis without shock, we suggest a time-limited course of rapid investigation and if concern for infection persists, the administration of antimicrobials within 3 hours from the time when sepsis was first recognized. |
| New | For adults with definite or probable sepsis and hypotension (i.e., septic shock) and who have an anticipated time to in-hospital medical evaluation of over 60 minutes, we “suggest” administering antimicrobial therapy in ambulance or flight. | Conditional/⊕○○○ | - |
| ⁕Remarks: | |||
| Prehospital antibiotic delivery should be implemented only after having a structured process in place to screen for sepsis in ambulance or flight, as discussed in recommendation 3. | |||
| New | For adults with sepsis or septic shock at high risk of infection with a specific MDR pathogen, we “suggest” using empirical antimicrobial therapy with coverage for this multidrug resistant pathogen. | Conditional/⊕○○○ | For adults with sepsis or septic shock at high risk of MRSA, we recommend using empiric antimicrobials with MRSA coverage over using antimicrobials without MRSA coverage. |
| ⁕Remarks: | For adults with sepsis or septic shock and high risk for MDR organisms, we suggest using two antimicrobials with gram-negative coverage for empiric treatment over one gram-negative agent. | ||
| Risk factors for MDR pathogens include colonization with the MDR pathogen of concern, previous infection with the MDR pathogen of concern, prolonged use of broad-spectrum antibiotics, and prolonged hospitalization in a unit with a high prevalence of the MDR pathogen of concern. | - | ||
| New | For adults with sepsis or septic shock at low risk of infection with a specific MDR pathogen, we “suggest against” using empirical antimicrobial therapy with coverage for this MDR pathogen. | Conditional/⊕○○○ | For adults with sepsis or septic shock at low risk of MRSA, we suggest against using empiric antimicrobials with MRSA coverage, as compared with using antimicrobials without MRSA coverage. |
| For adults with sepsis or septic shock and low risk for MDR organisms, we suggest against using two gram-negative agents for empiric treatment, compared with one gram-negative agent. | |||
| Revisited | For adults with sepsis or septic shock, we “suggest against” using empirical antifungal therapy. | Conditional/⊕⊕○○ | For adults with sepsis or septic shock at high risk of fungal infection, we suggest using empiric antifungal therapy over no antifungal therapy. |
| ⁕Remarks: | For adults with sepsis or septic shock at low risk of fungal infection, we suggest against empiric use of antifungal therapy. | ||
| Empiric antifungal therapy should be considered on a case-by-case basis in selected patients with sepsis or septic shock and risk factors for fungal infection, including immunosuppression, prolonged use of antibiotics, prolonged hospitalization, and intra-abdominal sources of infection. | |||
| New | For adults with sepsis or septic shock without risk factors for anaerobic infection, we “suggest” using an empiric antibiotic regimen without anaerobic coverage. | Conditional/⊕○○○ | - |
| ⁕Remarks: | |||
| When coverage of potential MDR pathogens is required, agents with anaerobic activity (e.g., piperacillin–tazobactam or carbapenems) are appropriate when alternative agents lacking anaerobic coverage are insufficient. | |||
| New | For adults with sepsis or septic shock with specific risk factors for anaerobic infection, we “suggest” using an empiric antibiotic regimen that includes anaerobic coverage. | Conditional/⊕○○○ | - |
| ⁕Remarks: | |||
| Risk factors for anaerobic infection include intra-abdominal or deep-seated gynecological/obstetric source of infection, necrotizing soft-tissue infection, head and neck infection, and central nervous system abscesses or empyema. | |||
| New | In mechanically ventilated adults with sepsis or septic shock in units with a low prevalence of antimicrobial resistance, we “suggest” using selective decontamination of the digestive tract. | Conditional/⊕⊕○○ | |
| Revisited | For adults with septic shock, we “suggest” using either invasive or noninvasive blood pressure monitoring. | Conditional/⊕○○○ | For adults with septic shock, we suggest using invasive monitoring of arterial blood pressure over noninvasive monitoring, as soon as practical and if resources are available. |
| ⁕Remarks: | |||
| Invasive blood pressure monitoring is advised in patients with shock who: require intermediate-to-high dose vasopressors, escalating doses of vasopressor, or multiple vasopressors; are receiving frequent arterial blood sampling; or have noninvasive blood pressure measurements which are inconsistent on repeated assessments. | |||
| Revisited | For adults with sepsis or septic shock, we “suggest” using capillary refill time to guide resuscitation as an adjunct to other measures of perfusion. | Conditional/⊕⊕○○ | For adults with septic shock, we suggest using capillary refill time to guide resuscitation as an adjunct to other measures of perfusion. |
| New | For adults with sepsis, we “suggest” measuring oxygenation by either pulse oximeter (SpO2) or arterial blood gas (SaO2) in conjunction with physical examination and clinical acumen. | Conditional/⊕○○○ | - |
| ⁕Remarks: | |||
| Arterial blood gas measurements are the gold standard for assessing oxygenation; include other important information such as pH, PacO2, lactate, and bicarbonate; and are preferable when available. SpO2/FiO2 by pulse oximeter may substitute for PaO2/FiO2 ratio but is less accurate in patients in shock, with darker skin tones, and/or with oxygen saturations <90% or >97%. | |||
| Revisited | For adults with sepsis and acute hypoxemic respiratory failure, we “suggest” titrating FiO2 to target either higher, more liberal oxygen levels or lower, conservative oxygen levels depending on patient factors and resource limitations. | Conditional/⊕⊕○○ | There is insufficient evidence to make a recommendation on the use of conservative oxygen targets in adults with sepsis-induced hypoxemic respiratory failure. |
| ⁕Remarks: | |||
| Although there was variability across trials informing this recommendation, most used a lower target of approximately 90%–93% SpO2 and a higher target of SpO2 ≥96%. | |||
| “In our practice”, panelists target SpO2 between 90% (IQR, 90%–92%) to 96% (IQR, 94%–98%) for patients with sepsis and acute hypoxemic respiratory failure. | |||
| Revisited | For adults with sepsis and acute hypoxemic respiratory failure, we “suggest” using HFNC as the initial therapy over noninvasive positive pressure ventilation. | Conditional/⊕⊕○○ | For adults with sepsis-induced hypoxemic respiratory failure, we suggest the use of high flow nasal oxygen over noninvasive ventilation. |
| New | For adults with sepsis and acute hypoxemic respiratory failure, we “suggest” using HFNC over high flow alternating with noninvasive positive pressure ventilation. | Conditional/⊕○○○ | - |
| Revisited | For adults with septic shock, we “suggest” using IV corticosteroids. | Conditional/⊕⊕○○ | For adults with septic shock and an ongoing requirement for vasopressor therapy we suggest using IV corticosteroids. |
| ⁕Remarks: | |||
| The typical corticosteroid used in adults with septic shock is IV hydrocortisone at a dose of 200 mg/day given as 50 mg intravenously every 6 hours or as a continuous infusion. It is suggested that this is commenced at a dose of norepinephrine or epinephrine ≥ 0.25 μg/kg/min at least 4 hours after initiation. | |||
| New | For adults with septic shock after the acute resuscitation phase, we “suggest” using active fluid removal. | Conditional/⊕○○○ | |
| ⁕Remarks: | |||
| Acute resuscitation refers to escalating doses of vasopressors, ongoing high doses of vasopressors, or needing ongoing volume expansion. Active fluid removal refers to diuretics and, if diuretics are insufficient, ultrafiltration or extracorporeal fluid removal. Factors to be considered when deciding to initiate active fluid removal include cardiorespiratory function, vasopressor dose, clinical course, peripheral edema, weight, and fluid balance. | |||
| New | Health systems should implement strategies to ensure clinicians have the knowledge and competency to support sepsis survivors and their families during the post-hospital recovery. | Good practice statement | - |
| New | Health systems should implement strategies to support sepsis survivors and their families during the post-hospital recovery. | Good practice statement | - |
| Revisited | For adult survivors of hospitalization for sepsis or septic shock who received invasive mechanical ventilation >48 hours, we “suggest” offering physical rehabilitation services after hospital discharge. | Conditional/⊕⊕○○ | For adult survivors of sepsis or septic shock receiving mechanical ventilation for > 48 hours or an intensive care unit stay of >72 hours, we suggest referral to a post-hospital rehabilitation program. |
| ⁕Remarks: | |||
| Physical rehabilitation services may vary in format, intensity, and duration, depending on locally available resources and patient needs. | |||
| Revisited | Adult survivors of hospitalization for sepsis or septic shock who demonstrate clinical symptoms of mental health disorders should be referred to appropriate healthcare professionals for evaluation and management. | Good practice statement | For adult survivors of sepsis or septic shock, we recommend assessment and follow-up for physical, cognitive, and emotional problems after hospital discharge. |
