What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Computer-assisted weaning programDevice
Also called Drager Evita Smartcare System
Closed-loop, knowledge-based, computer-assisted wean program initiated at the start of ventilator weaning.
Standard of Care weaningBehavioural
Evidence-based standard of care weaning process.
| Study group | Role | What they receive |
|---|---|---|
| Computer-assisted weaning | Experimental | Group assigned to the computer-assisted weaning program Receives: Device: Computer-assisted weaning program |
| Standard of care weaning | Active comparator | Group assigned to receive current, evidence-based, standard of care for discontinuation of mechanical ventilation. Receives: Behavioral: Standard of Care weaning |
What is being measured
The primary outcome is the main question the study is designed to answer.
Duration of Weaning
Duration of weaning was assessed as the time from the initiation of weaning (randomization) to the time of successful extubation (defined as 48 hours free of mechanical ventilation). Patients were followed for the duration of hospitalization and the time of weaning onset and successful liberation from the ventilator was noted.
Measured: Continuous (median weaning duration was 2 days)
Secondary outcomes (7)
Duration of ICU Stay
Duration of ICU stay after weaning initiation
Measured: from start of weaning to discharge from ICU, on average 1-2 weeks
Duration of Mechanical Ventilation
Duration of mechanical ventilation from weaning initiation
Measured: from start of weaning to liberation from ventilator, on average 1-2 days
Duration of Hospitalization
Measured: from start of weaning to discharge from hospital, on average 1-2 weeks
Inpatient Mortality
proportion of patients in each arm who died in the hospital
Measured: 28 days
Sedation Requirements
measure was not recorded
Measured: during weaning, on average 1-2 days
Number of Spontaneous Breathing Trials Prior to Extubation
Measured: from start of weaning to liberation from ventilator, on average 1-2 days
Complications (Death During Wean, Ventilator-associated Pneumonia During Wean, Self Extubation, Re-intubation)
This outcome is a composite outcome of the total number of participants with any one of the above-listed weaning-associated complications.
Measured: Duration of weaning (median 2 days)

Questions about this trial
What is this clinical trial studying?
A study testing Computer-assisted weaning program in people with Respiratory Insufficiency, run by Boston Medical Center at 1 site in United States.
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 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: stopped early, as of the sponsor's last update on 11 Dec 2017. 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 United States. 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 17 Aug 2011). 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?
Duration of Weaning (time frame: Continuous (median weaning duration was 2 days)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 11 Dec 2017; AzTrials last refreshed its copy on 6 Nov 2026.
