Acute respiratory distress syndrome: the Berlin Definition. Pub. Med. Abstract. The acute respiratory distress syndrome (ARDS) was defined in 1. American- European Consensus Conference (AECC); since then, issues regarding the reliability and validity of this definition have emerged. Using a consensus process, a panel of experts convened in 2. European Society of Intensive Care Medicine endorsed by the American Thoracic Society and the Society of Critical Care Medicine) developed the Berlin Definition, focusing on feasibility, reliability, validity, and objective evaluation of its performance.
A draft definition proposed 3 mutually exclusive categories of ARDS based on degree of hypoxemia: mild (2. Hg & lt; Pa. O2/FIO2 ≤ 3. Hg), moderate (1. Hg & lt; Pa. O2/FIO2 ≤ 2. Hg), and severe (Pa. O2/FIO2 ≤ 1. 00 mm Hg) and 4 ancillary variables for severe ARDS: radiographic severity, respiratory system compliance (≤4. L/cm H2. O), positive end- expiratory pressure (≥1.

ARDS from 4 multicenter clinical data sets and 2. ARDS from 3 single- center data sets containing physiologic information. The 4 ancillary variables did not contribute to the predictive validity of severe ARDS for mortality and were removed from the definition. Using the Berlin Definition, stages of mild, moderate, and severe ARDS were associated with increased mortality (2. CI, 2. 4%- 3. 0%; 3.

IQR, 5- 1. 7, respectively; P & lt; . Compared with the AECC definition, the final Berlin Definition had better predictive validity for mortality, with an area under the receiver operating curve of 0. CI, 0. 5. 61- 0. 5. CI, 0. 5. 20- 0. 5. P & lt; . 0. 01). This updated and revised Berlin Definition for ARDS addresses a number of the limitations of the AECC definition.
The approach of combining consensus discussions with empirical evaluation may serve as a model to create more accurate, evidence- based, critical illness syndrome definitions and to better inform clinical care, research, and health services planning.
