A Study of Communication Between Clinicians, Patients, and Families in the Intensive Care Unit (ICU) — TIME  

Mechanical Ventilation Clinical Trial

Official title: Optimizing Time-Limited Trials of Mechanical Ventilation in Acute Respiratory Failure (The TIME Study): A Mixed Methods Observational Study

Status Enrolling by invitation

Clinical Trial 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 him or her. 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.

Clinical Trial Description

This is a multi-site observational study that will investigate the time-limited trial approach to care for patients with critical illness, which is a trial of life support with milestones and a timeline to help evaluate whether the patient is improving. The primary objective of this study is to define the optimal care delivery processes of a time-limited trial for adult intensive care unit (ICU) patients who develop acute respiratory failure requiring mechanical ventilation. The two aims of this study are to: Aim 1: Map the current processes of time-limited trial care delivery for patients with acute respiratory failure. Aim 2: Elucidate the relationships between time-limited trials, their care delivery processes, and end-of-life outcomes for patients, surrogates, and ICU teams. For Aim 1, a focused ethnography of 50 time-limited trials will be done to characterize how trials are currently being done in the intensive care unit. This will include direct observation of ICU care provided to patients and real-time interviews with their surrogates and the ICU team members providing their care. Qualitative analyses will be used to characterize TLT activities and team member roles. These data will support the construction of a systems engineering process map, which is a visual tool that diagrams the sequence of process steps and serves as a time-limited trial process measure. For Aim 2, a prospective cohort of 5,810 patients with acute respiratory failure will be followed to evaluate relationships between time-limited trial exposure and ICU outcomes through a chart review and electronic health record (EHR) data abstraction. The extent to which trial care processes influence surrogate and ICU team member outcomes will be investigated by conducting surveys. Additionally, semi-structured interviews will be conducted with surrogates and ICU team members to investigate how time-limited trial processes work. The hypothesis is that optimal time-limited trial delivery will reduce intensive care unit length of stay for patients with acute respiratory failure and improve the intensive care unit experiences for their families and clinicians. ;
