Device: Low-intensity NPPV
Registration Number
NCT02985918

Primary Outcome Measures
NameTimeMethod
The need for endotracheal intubation during hospitalizationFrom randomization to discharge from hospital

Defined as the proportion of patients who needed for endotracheal intubation during hospitalization after randomization

Secondary Outcome Measures
NameTimeMethod
Live discharge from the hospitalFrom randomization to discharge from hospital

Defined as the proportion of patients with the exception of those who died and withdrawn treatment therapy during hospitalization after randomization.

Actual intubation during hospitalizationFrom randomization to discharge from hospital

Defined as the proportion of patients actually receiving intubation and invasive ventilation during hospitalization after randomization

The composite of actual intubation or avoiding intubation by crossover to high-intensity NPPVFrom randomization to discharge from hospital

Defined as the incidence of patients receiving actual intubation in the high-intensity NPPV group vs the composite incidence of actual intubation or avoiding intubation by crossover to high-intensity NPPV in case of intubation criteria in the low-intensity NPPV group) during hospitalization after randomization

Mortality at day 28Within 28 days since randomization
Intensive care unit admissionFrom randomization to discharge from hospital

Defined as the proportion of patients who transferred to ICU during hospitalization after randomization

Hospital readmission at day 90Within 90 days since randomization

Defined as the number of hospitalization days within 90 days since randomization

Length of hospital stay after randomizationFrom randomization to discharge from hospital

Defined as the number of hospitalization days since randomization

Invasive ventilator-free days at day 28Within 28 days since randomization

Defined as 28 minus the number of days with invasive ventilator (range, 0-28 days) since randomization

Need for endotracheal intubation at day 28Within 28 days since randomization

Defined as the proportion of patients who needed endotracheal intubation within 28 days since randomization

NPPV weaning successFrom randomization to discharge from hospital

Defined as the proportion of patients with persistent disconnection of NPPV without the presence of respiratory distress within the following 72 hours during hospitalization after randomization

Mortality in hospitalFrom randomization to discharge from hospital
Mortality at day 90Within 90 days since randomization
Length of hospital stayFrom hospital admission to discharge

Defined as the number of days for the index hospitalization

ICU-free days at day 28Within 28 days since randomization

Defined as 28 minus the number of days in the ICU (range, 0-28 days) since randomization

Actual intubation at day 28Within 28 days since randomization

Defined as the proportion of patients receiving intubation and invasive ventilation within 28 days after randomization
