Purpose
To determine the association between compliance with the Surviving Sepsis Campaign (SSC) performance bundles and mortality.
Design
Compliance with the SSC performance bundles, which are based ...on the 2004 SSC guidelines, was measured in 29,470 subjects entered into the SSC database from January 1, 2005 through June 30, 2012. Compliance was defined as evidence that all bundle elements were achieved.
Setting
Two hundred eighteen community, academic, and tertiary care hospitals in the United States, South America, and Europe.
Patients
Patients from the emergency department, medical and surgical wards, and ICU who met diagnosis criteria for severe sepsis and septic shock.
Methods
A multifaceted, collaborative change intervention aimed at facilitating adoption of the SSC resuscitation and management bundles was introduced. Compliance with the SSC bundles and associated mortality rate was the primary outcome variable.
Results
Overall lower mortality was observed in high (29.0 %) versus low (38.6 %) resuscitation bundle compliance sites (
p
< 0.001) and between high (33.4 %) and low (32.3 %) management bundle compliance sites (
p
= 0.039). Hospital mortality rates dropped 0.7 % per site for every 3 months (quarter) of participation (
p
< 0.001). Hospital and intensive care unit length of stay decreased 4 % (95 % CI 1–7 %;
p
= 0.012) for every 10 % increase in site compliance with the resuscitation bundle.
Conclusions
This analysis demonstrates that increased compliance with sepsis performance bundles was associated with a 25 % relative risk reduction in mortality rate. Every 10 % increase in compliance and additional quarter of participation in the SSC initiative was associated with a significant decrease in the odds ratio for hospital mortality. These results demonstrate that performance metrics can drive change in clinical behavior, improve quality of care, and may decrease mortality in patients with severe sepsis and septic shock.
OBJECTIVE:The Surviving Sepsis Campaign guidelines recommend obtaining a serum lactate measurement within 6 hours of presentation for all patients with suspected severe sepsis or septic shock. A ...lactate greater than 4 mmol/L qualifies for administration of early quantitative resuscitation therapy. We evaluated lactate elevation (with special attention to values > 4 mmol/L) and presence or absence of hypotension as a marker of clinical outcome.
DESIGN AND SETTING:The Surviving Sepsis Campaign developed a database to assess the overall effect of the sepsis bundles as a performance improvement tool for clinical practice and patient outcome. This analysis focuses on one element of the Surviving Sepsis Campaign’s resuscitation bundle, measuring serum lactate in adult severe sepsis or septic shock patients and its interaction with hypotension. This analysis was conducted on data submitted from January 2005 through March 2010.
SUBJECTS:Data from 28,150 subjects at 218 sites were analyzed.
INTERVENTIONS:None.
MEASUREMENTS AND MAIN RESULTS:Unadjusted analysis of the 28,150 observations from the Surviving Sepsis Campaign database demonstrated a significant mortality increase with the presence of hypotension in conjunction with serum lactate elevation greater than 2 mmol/L. On multivariable analysis, only lactate values greater than 4 mmol/L, in conjunction with hypotension, significantly increased mortality when compared with the referent group of lactate values less than 2 mmol/L and not hypotensive. Mortality was 44.5% in patients with combined lactate greater than 4 mmol/L and hypotension when compared with 29% mortality in patients not meeting either criteria.
CONCLUSIONS:Serum lactate was commonly measured within 6 hours of presentation in the management of severe sepsis or septic shock in this subset analysis of the Surviving Sepsis Campaign database in accordance with the Surviving Sepsis Campaign guidelines. Our results demonstrate that elevated lactate levels are highly associated with in-hospital mortality. However, only patients who presented with lactate values greater than 4 mmol/L, with and without hypotension, are significantly associated with in-hospital mortality and is associated with a significantly higher risk than intermediate levels (2–3 and 3–4 mmol/L). This supports the use of the cutoff of greater than 4 mmol/L as a qualifier for future clinical trials in severe sepsis or septic shock in patient populations who use quantitative resuscitation and the Surviving Sepsis Campaign bundles as standard of care.
OBJECTIVE:The Surviving Sepsis Campaign (SSC or “the Campaign”) developed guidelines for management of severe sepsis and septic shock. A performance improvement initiative targeted changing clinical ...behavior (process improvement) via bundles based on key SSC guideline recommendations.
DESIGN AND SETTING:A multifaceted intervention to facilitate compliance with selected guideline recommendations in the intensive care unit, emergency department, and wards of individual hospitals and regional hospital networks was implemented voluntarily in the United States, Europe, and South America. Elements of the guidelines were “bundled” into two sets of targets to be completed within 6 hrs and within 24 hrs. An analysis was conducted on data submitted from January 2005 through March 2008.
SUBJECTS:A total of 15,022 subjects.
MEASUREMENTS AND MAIN RESULTS:Data from 15,022 subjects at 165 sites were analyzed to determine the compliance with bundle targets and association with hospital mortality. Compliance with the entire resuscitation bundle increased linearly from 10.9% in the first site quarter to 31.3% by the end of 2 yrs (p < .0001). Compliance with the entire management bundle started at 18.4% in the first quarter and increased to 36.1% by the end of 2 yrs (p = .008). Compliance with all bundle elements increased significantly, except for inspiratory plateau pressure, which was high at baseline. Unadjusted hospital mortality decreased from 37% to 30.8% over 2 yrs (p = .001). The adjusted odds ratio for mortality improved the longer a site was in the Campaign, resulting in an adjusted absolute drop of 0.8% per quarter and 5.4% over 2 yrs (95% confidence interval, 2.5–8.4).
CONCLUSIONS:The Campaign was associated with sustained, continuous quality improvement in sepsis care. Although not necessarily cause and effect, a reduction in reported hospital mortality rates was associated with participation. The implications of this study may serve as an impetus for similar improvement efforts.
OBJECTIVE:To provide an update to “Surviving Sepsis Campaign Guidelines for Management of Sepsis and Septic Shock2012.”
DESIGN:A consensus committee of 55 international experts representing 25 ...international organizations was convened. Nominal groups were assembled at key international meetings (for those committee members attending the conference). A formal conflict-of-interest (COI) policy was developed at the onset of the process and enforced throughout. A stand-alone meeting was held for all panel members in December 2015. Teleconferences and electronic-based discussion among subgroups and among the entire committee served as an integral part of the development.
METHODS:The panel consisted of five sectionshemodynamics, infection, adjunctive therapies, metabolic, and ventilation. Population, intervention, comparison, and outcomes (PICO) questions were reviewed and updated as needed, and evidence profiles were generated. Each subgroup generated a list of questions, searched for best available evidence, and then followed the principles of the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system to assess the quality of evidence from high to very low, and to formulate recommendations as strong or weak, or best practice statement when applicable.
RESULTS:The Surviving Sepsis Guideline panel provided 93 statements on early management and resuscitation of patients with sepsis or septic shock. Overall, 32 were strong recommendations, 39 were weak recommendations, and 18 were best-practice statements. No recommendation was provided for four questions.
CONCLUSIONS:Substantial agreement exists among a large cohort of international experts regarding many strong recommendations for the best care of patients with sepsis. Although a significant number of aspects of care have relatively weak support, evidence-based recommendations regarding the acute management of sepsis and septic shock are the foundation of improved outcomes for these critically ill patients with high mortality.

Nominal groups were assembled at key international meetings (for those committee members attending the conference). A formal conflict of interest policy was developed at the onset of the process and enforced throughout. The entire guidelines process was conducted independent of any industry funding. A stand-alone meeting was held for all subgroup heads, co- and vice-chairs, and selected individuals. Teleconferences and electronic-based discussion among subgroups and among the entire committee served as an integral part of the development.
Methods
The authors were advised to follow the principles of the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system to guide assessment of quality of evidence from high (A) to very low (D) and to determine the strength of recommendations as strong (1) or weak (2). The potential drawbacks of making strong recommendations in the presence of low-quality evidence were emphasized. Recommendations were classified into three groups: (1) those directly targeting severe sepsis; (2) those targeting general care of the critically ill patient and considered high priority in severe sepsis; and (3) pediatric considerations.
Results
Key recommendations and suggestions, listed by category, include: early quantitative resuscitation of the septic patient during the first 6 h after recognition (1C); blood cultures before antibiotic therapy (1C); imaging studies performed promptly to confirm a potential source of infection (UG); administration of broad-spectrum antimicrobials therapy within 1 h of the recognition of septic shock (1B) and severe sepsis without septic shock (1C) as the goal of therapy; reassessment of antimicrobial therapy daily for de-escalation, when appropriate (1B); infection source control with attention to the balance of risks and benefits of the chosen method within 12 h of diagnosis (1C); initial fluid resuscitation with crystalloid (1B) and consideration of the addition of albumin in patients who continue to require substantial amounts of crystalloid to maintain adequate mean arterial pressure (2C) and the avoidance of hetastarch formulations (1B); initial fluid challenge in patients with sepsis-induced tissue hypoperfusion and suspicion of hypovolemia to achieve a minimum of 30 mL/kg of crystalloids (more rapid administration and greater amounts of fluid may be needed in some patients (1C); fluid challenge technique continued as long as hemodynamic improvement is based on either dynamic or static variables (UG); norepinephrine as the first-choice vasopressor to maintain mean arterial pressure ≥65 mmHg (1B); epinephrine when an additional agent is needed to maintain adequate blood pressure (2B); vasopressin (0.03 U/min) can be added to norepinephrine to either raise mean arterial pressure to target or to decrease norepinephrine dose but should not be used as the initial vasopressor (UG); dopamine is not recommended except in highly selected circumstances (2C); dobutamine infusion administered or added to vasopressor in the presence of (a) myocardial dysfunction as suggested by elevated cardiac filling pressures and low cardiac output, or (b) ongoing signs of hypoperfusion despite achieving adequate intravascular volume and adequate mean arterial pressure (1C); avoiding use of intravenous hydrocortisone in adult septic shock patients if adequate fluid resuscitation and vasopressor therapy are able to restore hemodynamic stability (2C); hemoglobin target of 7–9 g/dL in the absence of tissue hypoperfusion, ischemic coronary artery disease, or acute hemorrhage (1B); low tidal volume (1A) and limitation of inspiratory plateau pressure (1B) for acute respiratory distress syndrome (ARDS); application of at least a minimal amount of positive end-expiratory pressure (PEEP) in ARDS (1B); higher rather than lower level of PEEP for patients with sepsis-induced moderate or severe ARDS (2C); recruitment maneuvers in sepsis patients with severe refractory hypoxemia due to ARDS (2C); prone positioning in sepsis-induced ARDS patients with a Pa
