Trial summary

Expeditious, safe extubation is vitally important in the care of Intensive Care Unit (ICU) patients, as prolonged mechanical ventilation harms patients and failed extubation (i.e. re-intubation within 48 hrs) is associated with increased morbidity, mortality and costs. Read more about this study

About this study

Expeditious, safe extubation is vitally important in the care of Intensive Care Unit (ICU) patients, as prolonged mechanical ventilation harms patients and failed extubation (i.e. re-intubation within 48 hrs) is associated with increased morbidity, mortality and costs. The urgent need to improve extubation failure is further highlighted by current observations suggesting that COVID-19 patients are at increased risk of both early and late extubation failure. The investigators previously found that decreased respiratory rate variability (indicative of reduced adaptability and/or increased stress) during Spontaneous Breathing Trials (SBTs) predicted extubation failure and outperformed the best available predictive indices. Combining this predictive analytic with standardized extubation readiness checklists and risk mitigation strategies, the investigators created the Extubation Advisor (EA). The investigators recently completed a single-center phase I mixed methods observational study (n=117) wherein there was demonstrated technical feasibility (i.e. ability to generate 92% EA of reports) and clinician acceptance of the EA tool. In the current open-label, multi-center interventional phase I study, the investigators will assess the feasibility and initial perceptions of EA implementation in the intensive care unit by (1) evaluating the feasibility of patient enrolment, data collection, and EA report generation, and (2) performing a mixed-methods analysis of critical care physician and respiratory therapist perceptions of EA. Findings from this study will inform a future randomized controlled trial assessing EA outcomes compared to standard of care, with the intent of aiding bedside decision-making, enhancing care delivery, and improving outcomes in critically ill patients with and without COVID-19.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Extubation AdvisorDevice

    Participants undergoing a Spontaneous Breathing Trial (SBT) to assess readiness for extubation will be connected to a portable monitor displaying ECG, capnography, and other waveforms. This monitor will also be connected to a laptop containing the Extubation Advisor (EA) software. During the SBT, relevant patient information will be entered into the EA application and the EA application will record waveform data. When the SBT is complete, the EA application will analyze the waveform and patient data to generate a score summarizing the risk of extubation failure. A report will be generated and provided to the respiratory therapist and attending physician to help determine whether to proceed with extubation or not. Patients will be followed for 72 hours after extubation, when the clinical outcome case report form will be completed.

What is being measured

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

  1. Evaluate Feasibility of Enrolling and Consenting Greater Than 50% of Eligible Patients

    Feasibility of patient enrolment and consent will be evaluated by determining if greater than 50% of eligible patients are enrolled and consented

    Measured: Upon study completion, 4 months after study initiation

  2. Evaluate Feasibility of Capturing Greater Than 75% of Wave Form Data

    Feasibility of wave form data capture will be evaluated by determining if greater than 75% of the time, wave form data is captured

    Measured: Upon study completion, 4 months after study initiation

  3. Evaluate Feasibility of Generating and Delivering Greater Than 80% of Extubation Advisor Reports to the Attending Physician

    Feasibility of Extubation Advisor report generation will be evaluated by determining if greater than 80% of the time, an extubation report is successfully generated and delivered to the attending physician

    Measured: Upon study completion, 4 months after study initiation

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Extubation Advisor in people with Airway Extubation, run by Ottawa Hospital Research Institute at 1 site in Canada.

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 11 inclusion and 5 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 15 May 2025. 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 Canada. 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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 15 May 2025). 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?

Evaluate Feasibility of Enrolling and Consenting Greater Than 50% of Eligible Patients (time frame: Upon study completion, 4 months after study initiation). The study lists 3 primary outcomes in all. 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 NCT04708509, 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 15 May 2025; AzTrials last refreshed its copy on 30 Oct 2026.
