About this study

Official title: Early Lung Ultrasound Score Predicts Duration of Ventilation and ICU Mortality in COVID-19 Invasively Ventilated Patients

To assess the prognostic performance of an early global LUS score with respect to the mortality in ICU and duration of ventilation.

Read the detailed description

This is an international multicenter cohort study on data collected between March and April 2020. The first available lung ultrasound examination that used a 12-regions approach was used to calculate the global LUS score.

Patients are included if they fulfilled the following criteria: 1) admitted to one of the participating ICU; 2) for invasive ventilation; 3) for respiratory failure due to confirmed COVID-19; and 4) having had a LUS examination performed within the first week of start of invasive ventilation.

The primary and secondary outcomes were liberation from invasive ventilation and mortality.

Demographic, clinical and outcome variables will be presented as percentages for categorical variables and as medians with interquartile ranges (IQR) for continuous variables.

Receiver operating characteristics (ROC) analysis will be used to derive the prognostic discriminatory performance of global LUS score in determining succesful extubation and mortality at day 28. The Youden index will be used to derive the optimal cut-off. The association of global LUS with unfavourable outcomes are analyzed with Cox proportional hazard analysis (for successful extubation and alive at day 28), logistic regression models (mortality at day 28). Hazard ratio or odds ratio with 95% confidence intervals were calculated for each outcome.

What is being measured

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

  1. Liberation from invasive ventilation

    Patient who survived but remained invasively ventilated up to day 28 were marked without event. Patients who survived but were extubated were marked with an event at the day of successful extubation.

    Measured: 28 days

Secondary outcomes (1)
  1. Mortality

    Patient who survived up to day 28 were marked without event. Patients who survived but were extubated were marked with an event at the day of successful extubation.

    Measured: 28 days

Questions about this trial

What is this clinical trial studying?

An observational study of Covid19 and Ultrasound, run by Academisch Medisch Centrum - Universiteit van Amsterdam (AMC-UvA) at 1 site in Netherlands.

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 4 inclusion and 2 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 31 Jul 2024. 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 Netherlands. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Liberation from invasive ventilation (time frame: 28 days). 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 NCT04487769, 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 31 Jul 2024.
