简要总结
This study is an extension of the Spanish Initiative for Epidemiology, Stratification and Therapies of Acute respiratory failure (SIESTA) Network.
The present study is aimed to establish the epidemiological characteristics and clinical outcomes of 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 Spanish hospitals.
详细描述
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 Spanish hospitals. 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.
Since the study is prospective, with consecutive collection of clinically relevant data from patients and with the participation of several ICUs from different geographical regions of Spain, the findings would be highly generalizable. 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 developed by us for stratification of lung severity, and to examine the prognosis of hypoxemic respiratory failure, and risk factors associated with fatal outcome.

入选标准
- •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.
排除标准
- •No patients should be excluded (if they meet all the inclusion criteria), regardless of the underlying disease, estimated life expectancy, or duration of invasive mechanical ventilation.
结局指标
主要结局
Prevalence of hypoxemic acute respiratory failure
时间窗: 6 months
The investigators will calculate the prevalence in relation to: (i) total number of ICU admissions during the study period in all participating centers; (ii) total number of mechanically ventilated patients during the study period in all participating centers, and (iii) per ICU bed available in the participating centers over the study period.
次要结局
- death in the ICU(Intensive care unit stay [up to 60 days])
- death in the hospital(Hospital stay [Maximum 6 months])
