Shock, Septic
Why
  1. The study's listed conditions name Shock, Septic, a narrower term within Sepsis.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study population

Adult patients diagnosed with sepsis or septic shock, in accordance with the sepsis-3 criteria, admitted or intended to be admitted to the ICU.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Adult patients (≥22 years of age)
  • Diagnosis of sepsis or septic shock based on: the Third International Consensus Definitions (Sepsis-3 criteria) defined as at least one of the following criteria as determined by a treating physician or study physician investigator.

    • Sepsis: suspected or documented infection (i.e., use or intent to use antibiotics as an indicator) and organ dysfunction defined by a Sequential Organ Failure Assessment (SOFA) score ≥2
    • Septic shock: sepsis requiring vasopressors and serum lactate levels >2 mmol/L (18 mg/dL)
  • Admitted or intended to be admitted to the ICU
  • At least 3 mL plasma drawn and available for collection (or is anticipated to be able to be drawn and available) within 24 hours of (i.e., up to 24 hours after) the earliest diagnosis of sepsis or septic shock.

Exclusion criteria

Exclusion Criteria:

  • Prisoners or imprisonment at time of enrollment
  • Prior enrollment into this study
  • as approved by IRB is unable to be obtained.
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
