BACKGROUND: @entity881 (OF/MOF) was found to be the major complication after blunt @entity1230 during the last 25 years and was correlated with a high mortality rate. Recently, several publications reported a decreased ARDS-related mortality, but there is little information about mortality rates from posttraumatic MOF. The purpose of this study was to describe the development of MOF-related @entity204 after blunt @entity1230 during the last 25 years. METHODS: Blunt @entity1230 @entity1 with an Injury Severity Score (ISS) > 15 points were included in this evaluation. According to the year of @entity130 , the population was divided into five groups: years 1975-1980 (n = 317), years 1981-1985 (n = 308), years 1986-1990 (n = 246), years 1991-1997 (n = 368), and years 1998-1999 (n = 122). Main outcome measurements were @entity204 , cause of @entity204 , and length of ICU stay. @entity1 dying within the first 24 hours after @entity130 were excluded. All data indicated in the Results section are presented as mean +/- SEM. Continuous variables were compared by ANOVA. Ordinal variables were analyzed by chi2 contingency table analysis and, if significant, subsequently by Fisher's exact test (two-tailed test, p < 0.05). RESULTS: Mean ISS remained unchanged between 1975-1980 (ISS 29 +/- 1) and 1998-1999 (ISS 31 +/- 1) (p = 0.56). During the observation period, the mean age increased from 33 +/- 1 years (1975-1980) to 40 +/- 2 years (1998-1999) (p = 0.03). The overall incidence of OF/MOF slightly increased from 25.6% (1975-1980) to 33.6% (1998-1999) (p = 0.1). Length of ICU stay was not different between 1975-1980 (LOS: 14 +/- 1 d) and 1998-1999 (LOS: 19 +/- 2 d) (p = 1.0). The overall mortality decreased significantly, from 28.7% (1975-1980) to 13.9% (1998-1999) (p < 0.001). While the mortality due to severe @entity542 remained unchanged (1975-1980, 8.2%; 1998-1999, 9.0%) (p = 0.85), mortality due to OF/MOF decreased significantly (p < 0.001), from 18.0% (1975-1980) to 4.1% (1998-1999). The age of @entity1 dying from OF/MOF increased significantly (p = 0.04) during the observation period, from 44 +/- 3 years (1975-1980) to 63 +/- 6 years (1998-1999). CONCLUSION: Although MOF incidence remains unchanged, there is a significant fall in MOF-related mortality in @entity1 with severe @entity130 , and @entity204 from single organ failure is virtually absent. Severe @entity1545 is now the leading cause of @entity204 in @entity1 with severe @entity1230 admitted to the ICU.
