Study summary

Nearly 25% of Americans die in intensive care units (ICUs). Most deaths in ICUs are expected and involve the removal of ventilator support, or palliative withdrawal of mechanical ventilation (WMV). Prior work by the Principal Investigator (PI) found that patient suffering can be common; with 30-59% of patients going through this process experiencing distress. Thus, experts and national organizations have called for evidence to inform guidelines for WMV. This research study will 1) develop and refine a Comfort Measures Only Time out (CMOT) intervention consisting of a structured time out with check-list protocol for the ICU team (nurse, physician, respiratory therapist) to improve the process of WMV. and 2) Pilot test the CMOT intervention in 4 ICUs (2 medical/2 surgical) among 40 WMV patients.

Read the detailed description

This study will field test an ICU team-based timeout and checklist intervention, the Comfort Measures Only Time Out (CMOT), in 6 cases with 2 ICU teams (3 cases/team) and then further refine based on ICU team and expert feedback to create a final version of the CMOT. Then pilot testing of the final CMOT intervention will occur in 4 ICUs (2 medical/2 surgical) among 40 WMV patients (20/ICU sub-type). There are two groups of human subjects for this study: 1) Patients (n=46)- eligibility criteria are: 1. age ≥ 18, 2. decision made for WMV by extubation (but not yet extubated). and 2) ICU clinicians (n= approximately 138) (ICU nurses, physicians/APPs, and respiratory therapists)- eligibility will include: 1. Age > 18, and 2. provision of direct care to the patient for at least 1-hour pre-extubation. Verbal consent will be obtained from ICU clinicians by the RA. During the preparation period, the research team will conduct seminars to inform the ICU team about the study recruitment and data collection procedures. Each morning during the 12-month recruitment period, a research assistant (RA) will ask the ICU team to identify potentially eligible patients.

Study Procedures:

Pilot-testing of the CMOT will be in 4 ICUs (2 medical/2 surgical) among 40 WMV patients (20 patients/ICU type). Feasibility will be assessed by: recruitment, protocol adherence, acceptability to providers (e.g. helpfulness, endorse future use), and outcome measurement: rates of distressful episodes/person time alive (primary outcome). Outcomes will be compared with OBSERVE-WMV historical controls to help inform the design of a larger trial.

ICU sites: The CMOT intervention will be delivered at the ICU team level in 2 medical ICUs (16 beds), and 2 surgical ICUs at BIDMC (22 beds). Each ICU will have a designated CMOT champion.

ICU provider training:

The RA will collaborate with the CMOT Champion to compile a list of 'targeted' providers for training including ICU nurses, physicians, residents/fellows, mid-level providers, and respiratory therapists expected to provide care in the ICU over the next 13 months. The list will be refreshed every 2 months to reach new staff. The goal will be to have all targeted providers complete either the in-person or online training seminar (see below) within one month from the initial start-up for "prevalent" providers, or from start time in the ICU for new providers. The RA will track provider participation based on seminar sign-in logs or online training completion (see below). Weekly reminders will be emailed to non-compliant providers. It is estimated there will be \~50-60 targeted providers per ICU (20-25 nurses, 10-15 physicians, 10-15 fellows/resident physicians/mid-level providers, and 5 respiratory therapists). Provider involvement will be voluntary with verbal informed consent obtained during orientation.

Study arms

  • Experimental
    Check-list Arm

    This feasibility study will test an ICU team-based time and and check-list intervention, the Comfort Measures Only Time Out (CMOT). The CMOT is designed to improve ICU team communication and better address patient comfort at the end of life. Participants in the CMOT are intensive care unit clinicians who are caring for a patient who is about to undergo palliative withdrawal of mechanical ventilation at the end of life. Feasibility will be assessed by: recruitment rates, protocol adherence, and acceptability to clinicians. Patient level outcomes such as distressful episodes/person-time alive will also be collected as a component of routine care in this exploratory analysis. The maximum time any participant (ICU clinician or patient) will be participating in the study is about four hours.

What researchers measure

Primary outcomes

  1. Study recruitment rate

    Recruitment rate will be determined by the number of eligible participants enrolled divided by the total number of eligible participants.

    Time frame: At time of study completion (approximately 1-year)

  2. Protocol adherence

    Protocol adherence will be measured by the rate of completed CMOT check-lists among enrolled participants. This measure will be calculated as: the number of ICU clinician participants completing CMOT checklist divided by the number enrolled ICU clinician study participants.

    Time frame: At time of study completion (approximately 1-year)

Secondary outcomes

  1. Recommendation for future use

    Intensive care unit clinicians will complete a brief survey of their experience with the CMOT. The outcome measure will record whether the clinician would "recommend the CMOT be used in the future?" Response options will be recorded in the following categories: Yes, No, Don't Know, Prefer not to answer.

    Time frame: Surveys will be completed at three hours of withdrawal of mechanical ventilation, or within 72-hours. The measure will be reported at time of study completion (approximately 1-year)

Other outcomes

  1. Distressful episodes

    The frequency of distressful episodes from the will be measured by trained intensive care unit nurses using the respiratory distress observation scale (RDOS) \[Range 0-16, higher scores indicate greater distress\] and clinical pain observation tool (CPOT) \[Range 0-8, higher scores indicate greater pain\]. A composite outcome measure of either RDOS more than 2 or CPOT \> 0 will be used to define a distressful episode.

    Time frame: Measurement will occur at the time of withdrawal of mechanical ventilation (WMV) and until death or three hours after WMV. The measure will be reported at time of study completion (approximately 1-year).

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Oct 2023 to primary completion in Aug 2025, 22 months.

Of 105 non-industry interventional studies with no phase under Death, half reached primary completion within 24 months of starting (the median), counting those still running; a quarter within 14 and three quarters within 48. This study's 22 months is close to that.

Counting every sponsor, half of 109 studies reached it within 24 months; a quarter within 14 and three quarters within 48.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 18, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
