PRactice of VENTilation in COVID-19 Patients (PRoVENT-COVID)

The purpose of this national, multicenter service review is to determine and compare ventilation management in COVID-19 patients in the Netherlands, and to determine whether certain ventilation settings have an independent association with duration of ventilation. In every adult invasively ventilated COVID-19 patient from a participating ICU, granular ventilator settings and parameters will be collected from start of invasive ventilation for up to 72 hours. Follow up is until ICU and hospital discharge, and until day 90. The primary outcome includes main ventilator settings (including tidal volume, airway pressures, oxygen fraction and respiratory rate). Secondary endpoints are ventilator-free days and alive at day 28 (VFD-28); duration of mechanical ventilation; use of prone positioning and recruitment maneuvers; duration of ICU and hospital stay; incidence of kidney injury; and ICU, hospital, 28-day and 90-day mortality.
