Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • Adult, Older adult

Study population: Patients with confirmation of covid-19 and with length of stay in the intensive care unit greater than 48 hours will be selected for the intubated and non-intubated groups. For the intubated group, patients who underwent endotracheal intubation after 48 hours of admission to the intensive care unit will be selected. For the non-intubated group, those patients who were not intubated during their stay in the intensive care unit will be selected.

Who may be able to join

  • The inclusion criteria will be individuals with confirmed diagnosis of COVID-19 by RT-PCR (reverse- transcriptase polymerase chain reaction), with minimum length of stay of 24 hours in the ICU and, patients who sign the free and clarified consent.

Who cannot join

  • The exclusion criteria for participation in the study will be as follows: (1) patients under the age of 18; (2) patients with a negative laboratory test for COVID-19; (3) patients in need of emergency intubation; (4) patients who underwent previous endotracheal intubation at the same hospitalization.

About this study

This observational and retrospective study will follow the recommendations of the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE). The aim is to verify and analyze the clinical and laboratory variables with prediction capability for indication of invasive ventilatory support in patients with COVID-19. The present study will be carried out in specific care units for patients with suspected or confirmed COVID-19. Individuals with suspected or clinical diagnosis of COVID-19, with a minimum hospital stay of 24 hours and submitted to oxygen therapy or non-invasive ventilation will be selected. Clinical and laboratory variables will be collected from the moment of admission and every 12 hours until the third day of hospitalization. The primary outcome will be rate of endotracheal intubation, while secondary outocomes will be lenght of stay in intensive care unit, and hospital, as well as mortality rate.

What is being measured

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

  1. Identify clinical and laboratory variables that may be associated with the need of endotracheal intubation in the first 72 hours of admission to the intensive care unit.

    Vital signs will be collected through the cardiac monitor and clinical evaluation from the moment of admission until the third day of hospitalization, every twelve hours and full blood count and biochemistry data will be collected from patients at admission until the third day of hospitalization in the intensive care unit

    Measured: 3 days

Secondary outcomes (5)
  1. time to endotracheal intubation

    It will be collected from the date of intensive care unit admission until the date of endotracheal intubation

    Measured: 28 days

  2. length of stay in the ICU

    It will be collected from the date of intensive care unit admission until the outcome of discharge from the intensive care unit or death.

    Measured: 6 months

  3. length of hospital

    It will be collected from the date of intensive care unit admission until the outcome of hospital discharge or death.

    Measured: 12 months

  4. mechanical ventilation days

    It will be collected from the date of intubation in the intensive care unit until the date of extubation or up to 48 hours off mechanical ventilation in cases of tracheostomized patients and/or until the outcome of death

    Measured: 6 months

  5. hospital mortality

    Mortality will be collected during the period of hospitalization

    Measured: 12 months

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 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 30 Jan 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Brazil. 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?

Identify clinical and laboratory variables that may be associated with the need of endotracheal intubation in the first 72 hours of admission to the intensive care unit. (time frame: 3 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 NCT05663528, 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 30 Jan 2024.
