Abstract

BACKGROUND: In a single-center study published more than a decade ago involving patients presenting to the emergency department with severe sepsis and septic shock, mortality was markedly lower among those who were treated according to a 6-hour protocol of early goal-directed therapy (EGDT), in which intravenous fluids, vasopressors, inotropes, and blood transfusions were adjusted to reach central hemodynamic targets, than among those receiving usual care. We conducted a trial to determine whether these findings were generalizable and whether all aspects of the protocol were necessary. METHODS: In 31 emergency departments in the United States, we randomly assigned patients with septic shock to one of three groups for 6 hours of resuscitation: protocol-based EGDT; protocol-based standard therapy that did not require the placement of a central venous catheter, administration of inotropes, or blood transfusions; or usual care. The primary end point was 60-day in-hospital mortality. We tested sequentially whether protocol-based care (EGDT and standard-therapy groups combined) was superior to usual care and whether protocol-based EGDT was superior to protocol-based standard therapy. Secondary outcomes included longer-term mortality and the need for organ support. RESULTS: We enrolled 1341 patients, of whom 439 were randomly assigned to protocol-based EGDT, 446 to protocol-based standard therapy, and 456 to usual care. Resuscitation strategies differed significantly with respect to the monitoring of central venous pressure and oxygen and the use of intravenous fluids, vasopressors, inotropes, and blood transfusions. By 60 days, there were 92 deaths in the protocol-based EGDT group (21.0%), 81 in the protocol-based standard-therapy group (18.2%), and 86 in the usual-care group (18.9%) (relative risk with protocol-based therapy vs. usual care, 1.04; 95% confidence interval [CI], 0.82 to 1.31; P=0.83; relative risk with protocol-based EGDT vs. protocol-based standard therapy, 1.15; 95% CI, 0.88 to 1.51; P=0.31). There were no significant differences in 90-day mortality, 1-year mortality, or the need for organ support. CONCLUSIONS: In a multicenter trial conducted in the tertiary care setting, protocol-based resuscitation of patients in whom septic shock was diagnosed in the emergency department did not improve outcomes.

  • Early detection and appropriate treatment of sepsis are associated with a significant mortality benefit in hospitalized patients.

    “Early detection and appropriate treatment of sepsis have been associated with a significant mortality benefit in hospitalized patients.1,2,3”

    From External validation of a widely implemented proprietary sepsis prediction model in hospitalized patients (2021) · cites this paper as [2]

    The paper’s introductory passage reports a prior emergency-department study in which a 6-hour treatment protocol significantly reduced mortality among patients with severe sepsis or septic shock. But the ProCESS Discussion says its own trial found no mortality advantage for protocol-based resuscitation over bedside care, and that it did not assess settings where septic shock was not recognized promptly. The source therefore supports a narrower treatment finding, not the broader claim about early detection and treatment in hospitalized patients. (LLM, conf=0.86)

  • In the PROCESS, ARISE and PROMISE trials, the average volume of fluid received pre-randomization was in the range of 30 mL/kg, suggesting that this fluid volume has been adopted in routine clinical practice.

    “In the PROCESS (64), ARISE (65) and PROMISE (66) trials, the average volume of fluid received pre-randomization was also in the range of 30 mL/kg, suggesting that this fluid volume has been adopted in routine clinical practice (67).”
  • The observed reductions compare favorably with other sepsis intervention studies.

    “The observed reductions in ICU length of stay (1.8 days), mechanical ventilation duration (2.3 days), and 28-day mortality (5.7%) are clinically meaningful and compare favorably with other sepsis intervention studies22,23.”

  • The model has a 38% greater mortality reduction than Yealy et al.

    “Supplementary Table 8 benchmarks our model against prior studies, demonstrating a 2.1-fold longer lead time than Seymour et al16and a 38% greater mortality reduction than Yealy et al.23.”

    From Machine learning predicts sepsis deterioration trajectories. (2026) · cites this paper as Yealy et al.23

    The Results > Outcomes passage reports no significant mortality reduction with protocol-based care compared with usual care (19.5% versus 18.9%). The paper does not assess the citing authors’ model or provide a 38% comparison, so its findings cannot verify the claimed benchmark. (LLM, conf=0.76)

    Experimental — accuracy not yet measured
  • The four largest sepsis resuscitation trials administered moderate to large fluid volumes during the first 72 hours.

    “The four largest clinical trials in sepsis resuscitation used moderate to large amounts of fluids in the first 72 h.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
