About this study
Official title: Pragmatic Investigation of Volume Targeted Ventilation-1 (PIVOT-1)
This proposal will test the feasibility of implementing an assist volume control ventilation protocol in patients receiving mechanical ventilation in the medical intensive care unit. The trial will consist of a before-and-after trial design of block assignment to either adaptive pressure control (baseline) or assist volume control .
This is a feasibility study looking at the management of patients in the ventilator.
Read the detailed description
Over the course of 6 weeks, a before-and-after trial design of adaptive pressure control and assist volume control will be conducted.
Pre-trial planning phase: study protocols will be reviewed with key stakeholders (respiratory therapy providers and medical teams)
Weeks 1-2: data will be collected on our current adaptive pressure control ventilator protocol.
Week 3: The investigators will implement an assist volume control protocol. . Patients already on mechanical ventilation will be converted to assist volume control; however, these patients will not be included in the primary analysis.In accordance with the Consolidated Framework For Implementation Research (CFIR) approach, after 1 week of assist volume control the investigators will engage in quantitative and qualitative feedback with care providers to identify facilitators and barriers of assist volume control implementation.
Week 4-6: If the investigators identify substantial barriers, the investigators will pause and alter the protocol. If not, the investigators will continue assist volume control for an additional 2 weeks.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
mode of mechanical ventilationProcedure or surgery
Adaptive Pressure Control mechanical ventilation is a dual controlled mode that is designed to auto-control flow and minimize inspiratory pressure while delivering a provider-determined tidal volume. Assist Volume Control mechanical ventilation is a mode in which the respiratory care provider determines patient tidal volume and flow.
| Study group | Role | What they receive |
|---|---|---|
| Adaptive Pressure Control | Active comparator | The Adaptive Pressure Control arm is the baseline mode/protocol for medical intensive care unit mechanical ventilation Receives: Procedure: mode of mechanical ventilation |
| Assist Volume Control | Active comparator | The assist volume control arm is the new protocol that will be implemented and tested for feasibility Receives: Procedure: mode of mechanical ventilation |
What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of patients receiving Assist Volume Control
The primary outcome for the PIVOT-1 pilot is feasibility of Assist Volume Control implementation. We define feasibility in this study as 80% of patients receiving Assist Volume Control within 1 hour of initiation of intensive care unit mechanical ventilation
Measured: 1 hour
Secondary outcomes (5)
assist volume control duration
A secondary feasibility outcome will be >70% of ventilated time on Assist Volume Control during the first 24 hours of mechanical ventilation.
Measured: 24 hours
Percentage of mode crossover
A secondary feasibility outcome will include <10% crossover to the alternative mode
Measured: 2 weeks
exhaled tidal volume
exhaled tidal volume will be compared between modes using data extracted from the critical care data capsule.
Measured: 2 weeks
Number of ventilator free days
vent free days will be compared between the modes using data from the critical care data analytics platform
Measured: 28 days
intensive care length of stay
intensive care unit length of stay will be compared between the modes using data from the critical care data analytics platform
Measured: 28 days

Questions about this trial
What is this clinical trial studying?
A study testing mode of mechanical ventilation in people with Respiratory Failure and Acute Respiratory Distress Syndrome (ARDS), run by Wake Forest University Health Sciences 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 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 7 Jul 2023. 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?
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?
Percentage of patients receiving Assist Volume Control (time frame: 1 hour). 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 NCT03909854, which also lists 17 linked publications.
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 7 Jul 2023.
