Outcome from critical care in the "oldest old" @entity130 XXXX .

@entity1 @entity697 @entity130 @entity954
This study evaluated the "oldest old" Intensive Care Unit (ICU) @entity130 @entity1 , defined as @entity1 of age 75 and over, to determine the relationships between age, injury magnitude, physiologic severity of illness, and outcome in this group, compared with younger @entity130 @entity1 . Of 1,039 consecutive @entity954 ( @entity954 ) @entity1 with complete data, 45 were in the Oldest group, 54 were in the Elderly group (ages 65 to 74), and 940 were in the Younger group (age < 65). Age, sex, and type of @entity130 (penetrating versus blunt) did not predict outcome. The Injury Severity Score (ISS) was significantly higher in the Oldest group than in the other groups (p = 0.0005), but the @entity130 Score was the same for all groups. The proportion of Oldest group @entity1 with ISS > or = 20 was significantly higher than for Elderly and Younger group @entity1 (p = 0.0002 and p < 0.00005, respectively). The @entity697 ( @entity697 ) on the first @entity954 day was the best outcome predictor for all age groups, along with maximum @entity697 during the @entity954 stay (p < 0.00005 for both). When @entity1 were stratified by ISS, there was a statistically significant difference in day 1 @entity697 among age groups for most ISS categories, with higher @entity697 associated with advancing age. The oldest old fare worse with @entity130 because their injury is more severe (higher ISS) and because their physiologic response to a given level of injury is exaggerated (higher @entity697 ). However, once the oldest old are stratified by @entity697 , their outcome parallels that of their younger @entity130 cohorts.(ABSTRACT TRUNCATED AT 250 WORDS)
