Abstract
Introduction: Distress is experienced by more than 30% of patients during palliative withdrawal of mechanical ventilation at the end of life in the intensive care unit. There is a lack of high-quality evidence for specific approaches to risk factor identification and management of distress during this process. Structured "time-outs" and checklist interventions improve surgical outcomes and have been widely adopted in procedural care, but they have not been tested for use at end-of-life in intensive care unit settings.
Methods: We describe the development and planned testing of a novel time-out checklist intervention, the Comfort Measures Only Time Out (CMOT) in a non-randomized single arm pilot study. Intervention development was guided by published literature and a structured inter-professional advisory panel. The intervention will be tested by clinical teams caring for 46 patients undergoing palliative withdrawal of mechanical ventilation. Nurses, physicians, advanced practice providers, and respiratory therapists will convene within an hour before withdrawal of mechanical ventilation to complete the checklist. Implementation outcomes, including feasibility, will be measured by a 12-question survey and by clinician protocol adherence. Effect size calculations will determine power for future randomized controlled trials testing efficacy of the CMOT in reducing patient distress.
Discussion: This protocol will pilot test the feasibility of the CMOT, a structured time-out and checklist intervention, for WMV in the ICU. The study will inform potential changes to the protocol and intervention for a future randomized control trial. The CMOT is grounded in a quality and safety framework already adopted in procedural and critical care settings. Given high rates of distress, the CMOT will fill an identified gap in evidence surrounding the process of WMV.

期刊介绍:
Pilot and Feasibility Studies encompasses all aspects of the design, conduct and reporting of pilot and feasibility studies in biomedicine. The journal publishes research articles that are intended to directly influence future clinical trials or large scale observational studies, as well as protocols, commentaries and methodology articles. The journal also ensures that the results of all well-conducted, peer-reviewed, pilot and feasibility studies are published, regardless of outcome or significance of findings. Pilot and feasibility studies are increasingly conducted prior to a full randomized controlled trial. However, these studies often lack clear objectives, many remain unpublished, and there is confusion over the meanings of the words “pilot” and “feasibility”. Pilot and Feasibility Studies provides a forum for discussion around this key aspect of the scientific process, and seeks to ensure that these studies are published, so as to complete the publication thread for clinical research.
