Mortality in ARDS: ACURASYS study. The hazard ratio for death at 90 days in the cisatracurium group, as compared with the placebo group, was 0.68 https://www.nejm.org/doi/full/10.1056/nejmoa1005372

Has Mortality from Acute Respiratory Distress Syndrome Decreased over Time? A Systematic Review

It is commonly stated and assumed that mortality from acute respiratory distress syndrome (ARDS) is decreasing.

We found that mortality from ARDS has not decreased substantially since the publication of a consensus definition in 1994. Based on our findings, a baseline mortality risk from ARDS of 40 to 45% for observational studies and 35 to 40% for randomized control trials should be expected. These results highlight the need for future effective therapeutic interventions for this highly lethal syndrome.

From Up To Date:

Numerous studies suggest that survival has improved over time [2,9,10,11]. As an example, an observational study of 2451 patients who had enrolled in ARDSNet randomized trials found a fall in mortality from 35 to 26 percent between 1996 and 2005 [10]. To the extent that mortality may be decreasing with time, several issues should be considered:

● It is not known if mortality has decreased among patients who received their care outside of a specialized center or a clinical trial.

● The improved mortality may be attributable to patients who have ARDS related to risk factors other than sepsis, such as trauma [9].

● To the extent that mortality has decreased, the reasons are uncertain. Likely causes include better supportive care and improved ventilatory strategies, such as low tidal volume ventilation [10,12,13]
