Outcome Measures

Primary Outcomes (3)

  • Informed consent rate

    A successful informed consent rate will be defined as ≥70% of substitute decision makers or patients approached choosing to participate in this trial

    Informed consent rate will be measured over a 1 year period of the pilot study

  • Recruitment rate

    A successful recruitment rate will be achieving at least 15 patients over the 1 year period.

    Recruitment rate will be measured over the one year of the pilot study.

  • Protocol adherence rate

    An adherence rate of at least 80% will be considered successful.

    Protocol adherence will be measured for each study patient, and compiled over the duration of the pilot study (i.e. 1 year).

Secondary Outcomes (6)

  • 28-day mortality

    Up to Day 28

  • In-hospital mortality

    Up to 365 days

  • ICU length of stay

    Up to 365 days

  • Hospital length of stay

    Up to 365 days

  • Length/duration of mechanical ventilation

    Up to 365 days

  • +1 more secondary outcomes
