About this study

The goal of this clinical trial is to learn whether the choice of ventilator mode for patients on breathing machines in the intensive care unit affects their survival and recovery. To do this, researchers will assign the entire participating intensive care unit to one of the three available ventilator modes, alternating which mode is assigned in random sequence every 2 months. The main question it aims to answer is: Does the choice between volume control, pressure control, and adaptive pressure control affect the number of days that patients are alive and free of the breathing machine?

Read the detailed description

The MODEM trial is a cluster-randomized, cluster-crossover clinical trial comparing the effectiveness of three ventilator modes (volume control vs pressure control vs adaptive pressure control) for mechanical ventilation of critically ill adults at multiple centers. A total of 4,785 critically ill adults receiving invasive mechanical ventilation in intensive care units will be enrolled and included in the primary analysis. Each study unit will be assigned to a ventilator mode and will switch between modes every 2 months in an order determined by randomization. Enrolled patients will be assigned to receive volume control, pressure control, or adaptive pressure control according to the mode assigned to the unit at the time they were enrolled. The primary outcome will be ventilator-free days in the first 28 days, and the secondary outcome will be all-cause, 28-day in-hospital mortality.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Ventilator-free days in the first 28 days

    The number of calendar days between enrollment and 28 days after enrollment, on which the patient is alive and free of invasive mechanical ventilation. Receipt of invasive mechanical ventilation will be considered to end when patients undergo the final tracheal extubation or disconnection of the ventilator from a tracheostomy tube between enrollment and day 28.

    Measured: From enrollment to 28 days after enrollment

Secondary outcomes (1)
  1. All-cause, 28-day, in-hospital mortality

    All-cause, 28-day, in-hospital mortality, defined as death from any cause occurring between enrollment and 28 days after enrollment with outcome ascertainment ending at hospital discharge.

    Measured: From enrollment to 28 days after enrollment

Model description
In the MODEM trial, the entire study ICU will be assigned to a single ventilator mode (cluster-randomized) and the ICU will switch between volume control, pressure control, and adaptive pressure control modes every two months in a randomly generated sequence (cluster-crossover). Enrolled patients will be assigned to only one group at the time of their enrollment.
