About

This study is aimed to establish the epidemiological chacacteristics and clinical outcomes of mechanically ventilated patients with acute hypoxemic respiratory failure admitted in a network of hospitals from Wales (U.K.).

Full description

The present study is aimed to establish the epidemiological characteristics and clinical outcomes of adult mechanically ventilated patients with acute hypoxemic respiratory failure [defined as a PaO2/FiO2 ≤300 mmHg on positive end-expiratory pressure (PEEP) of 5 cmH2O or more and FiO2 of 0.3 or more] admitted in a network of hospitals from Wales (U.K.). Although there are few previous published observational studies examining the incidence and mortality of patients with acute respiratory failure and ARDS, there are no studies specifically assessing the epidemiological characteristics, patterns of ventilation and clinical outcomes in patients with acute hypoxemic respiratory failure in the current era of lung protective ventilation. This study will be done simultaneously with the PANDORA (NCT03145974) in Spain.

The study is aimed to improve the knowledge on the epidemiology and outcome of ventilated patients, to identify the percentage of patients developing ARDS under the current definition, to validate a bedside scoring system for stratification of lung severity, and to examine the prognosis of hypoxemic respiratory failure, and risk factors associated with fatal outcome.

Enrollment: 1,100 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Age ≥18-year old.
• Endotracheal intubation and mechanical ventilation, independent of whether the need for ventilatory support is shorter or longer than 24 hours. Only patients receiving invasive mechanical ventilation can be included, although patients could have been on non-invasive ventilation before intubation.
• PaO2/FiO2 ≤300 mmHg on invasive mechanical ventilation with a PEEP of 5 cmH2O or more, and with a FiO2 of 0.3 or more.

Exclusion criteria

• No patients shhould be excluded (if they meet all the inclusion criteria), regardless of the underlying disease, estimated life expectancy, or duration of invasive mechanical ventilation.
