Brief Summary
The purpose of this study is to investigate a specific approach to patient care called a time-limited trial (TLT). This approach is sometimes used for people who develop critical illness and are cared for in an intensive care unit (ICU). A time-limited trial is a plan made together by medical teams, patients with critical illness (if they can take part), and their families or other important people helping to make their healthcare decisions. A time-limited trial starts with a discussion of the patient's goals and wishes. Then, a plan is made to use ICU treatments for a set period of time to give the patient the chance to recover. After this time, the patient's response to treatment will be reviewed to help guide what to do next. Medical teams consider this kind of plan when it is not clear if a patient can recover to a quality of life that is acceptable to them. With a time-limited trial, patients, families, and medical teams experience this uncertainty together. The main goal of this study is to find the best way to use TLTs for patients in the ICU who have trouble breathing and need mechanical ventilation to help them breathe. The hypothesis is that optimal time-limited trial delivery will reduce the time patients with acute respiratory failure spend in the ICU and will improve the intensive care unit experiences for their families and clinicians.

Outcome Measures
Primary Outcomes (4)
Intensive Care Unit (ICU) length of stay
Cumulative number of days that participant stays in the intensive care unit.
Through participant study completion, an average of 8 days
Surrogate end-of-life intensive care unit (ICU) experience
Surrogate end-of-life intensive care unit (ICU) experience will be measured using the Family Satisfaction in the Intensive Care Unit (FS-ICU) questionnaire. The FS-ICU is a 24 item questionnaire that evaluates family members' satisfaction with their intensive care unit experience. Each question is scored on a 5-point scale from 1 (worst) to 5 (best). The total scores are then converted to a scale from 0 to 100, where 0 is the least satisfied and 100 is the most satisfied.
Between 4 and 16 weeks after participant's hospital discharge
Intensive Care Unit (ICU) team acute moral distress
Intensive Care Unit (ICU) team acute moral distress will be measured using the Moral Distress Thermometer (MDT). The MDT first presents a definition of moral distress, then asks the respondent to rate their distress related to a specific context on a 10-point scale from 0 (none) to 10 (worst possible) moral distress.
Up to 14 days after participant's hospital discharge
Direct observation of intensive care unit (ICU) care
Direct observations will include observations of interactions that are pertinent to time-limited trials (e.g., daily interprofessional rounds, nursing shift-change handoffs) and family meetings, including both formal (e.g., in a private conference room) or informal (e.g., on medical rounds or at the bedside) discussions between members of the ICU team, surrogates, patients (if able), and other family members. Observations will be documented using field notes, and family meetings will be audio-recorded and transcribed verbatim. Qualitative analysis of field notes and written transcripts will be done to look for themes and trends that emerge from the data.
Through participant study completion, an average of 8 days
Secondary Outcomes (10)
In-hospital mortality

Patient and family centeredness of care
Between 4 and 16 weeks after participant's hospital discharge
Surrogate Heard and Understood Measure
Between 4 and 16 weeks after participant's hospital discharge
- +5 more secondary outcomes
