About this study

Official title: Can Venous Lactate Predict the Progression to Overt Septic Shock and Mortality in Non-elderly Sepsis Patients Without Hemodynamic Shock in Emergency Department?

To investigate the role of initial venous lactate in predicting the severity progression to overt septic shock and 30-day mortality in non-elderly patients without hemodynamic shock who suspected to have acute infections.

Read the detailed description

Blood lactate is one of the markers that can predict the organ failures and mortality in emergency department (ED) patients with sepsis. Regarding its predictive role in the clinical deterioration in normotensive sepsis patients, a recent prospective observational study of the patients with moderately-high serum lactate (2.0-3.9 mmol/L) showed that one-forth of the patients eventually developed progressive organ dysfunctions or required vasopressor or mechanical ventilator. Unfortunately, low serum lactate (< 2.5 mmol/L) was still found up to 50% of overt septic shock patients, even in vasopressor-dependent cases. For the prognostic role on mortality, numbers of articles showed that blood lactate can also predict death in sepsis patients, especially in those who are elderly and critically-ill. However, no previous study was done in younger patients since lactate kinetics in the body may differ among the age groups. The primary aim of our study is to investigate the role of initial venous lactate levels in predicting the chance of severity progression to overt septic shock especially in non-elderly patients who suspected to have acute infections and without hemodynamic shock in ED. The secondary outcomes are to evaluate its prognostic role on hospital length of stay and 30-day mortality of this target population.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Proportion of the Patients Who Require Vasopressor/Mechanical Ventilator

    Proportion of the patients in each cohort who require vasopressor/mechanical ventilator to maintain their vital signs in the next 72 hours after venous lactate measurement.

    Measured: 72 hours after venous lactate measurement

Secondary outcomes (2)
  1. All-cause Mortality Rates

    Electronic database retrieval of in- and outpatient clinical records together with telephone follow-ups to the patients or their contact personnel are employed to every case in the next 30 days after the day of presentation to the emergency department to identify the deceased cases. All-cause mortality rates of each cohort will be compared by the survival analysis.

    Measured: 30 days after the day of presentation to the emergency department

  2. Hospital Length of Stay

    Numbers of days spent in the hospital since the emergency department arrival to hospital discharge

    Measured: Patients will be followed for the duration of hospital stay, an expected average of 7 days

Questions about this trial

What is this clinical trial studying?

An observational study of Sepsis and Disease Progression, run by Chulalongkorn University at 1 site in Thailand.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 2 Dec 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Thailand. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 7 May 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proportion of the Patients Who Require Vasopressor/Mechanical Ventilator (time frame: 72 hours after venous lactate measurement). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01947127, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Dec 2016.
