[The incidence and mortality of ARDS at Landspítali - The National University Hospital of Iceland 2004-2008].

Objective: A retrospective study of the incidence, causes, mortality and treatment of patients with ARDS at Landspítali The National University Hospital of Iceland during the five year period 2004-2008 and comparing the results with an earlier study for the period 1988-1997.

Materials And Methods: All ICU admissions during the period 2004-2008 were reviewed, selecting patients according to the American-European consensus criteria for ARDS. Data were collected on age, gender, causes, length of stay, ventilator treatment and survival.

Average age was 55 years, 55% were males, length of stay was 13 days and hospital stay 24 days. ICU mortality was 30% and 90 day mortality was 39%.

Conclusion: The incidence of ARDS seems to have increased some-what during the period 1988-1997. Mortality has decreased significantly probably due to improvements in intensive care treatment, especially ventilator treament with the use of lung protective ventilation, high frequency oscillation, prone position and ECMO.
