Injured XXXX with very high blood @entity285 concentrations.

@entity1 @entity131 @entity772 @entity285 @entity204 @entity130
OBJECTIVE: Most data regarding high blood @entity285 concentrations (BAC) >= 400 mg/dL have been from @entity285 @entity204 . Few studies have described this group and reported their @entity285 consumption patterns or outcomes compared to other @entity130 @entity1 . We hypothesised @entity130 @entity1 with very high BACs arrived to the @entity130 centre with less severe @entity130 than their sober counterparts. METHOD: Historical cohort of 46,222 @entity1 admitted to a major @entity130 centre between January 1, 2002 and October 31, 2011. BAC was categorised into ordinal groups by 100 mg/dL intervals. @entity285 questionnaire data on frequency and quantity was captured in the BAC >= 400 mg/dL group. The primary analysis was for BAC >= 400 mg/dL. RESULTS: BAC was recorded in 44,502 (96.3%) @entity1 . Those with a BAC >= 400 mg/dL accounted for 1.1% (147) of BAC positive cases. These @entity1 had the lowest proportion of severe @entity130 and in-hospital death in comparison with the other @entity285 groups (p<0.001). In adjusted analysis, the risk for severe injury increased with the BAC groups between 1 and 199 mg/dL and was not different or decreased for groups above 200 mg/dL in reference to the BAC negative group (test for trend p=0.001). BAC >= 400 group encountered more @entity130 caused by @entity130 in comparison with the other @entity285 groups (p<0.001), and the group comprised mainly of falls. Admission Glasgow @entity772 Scale was a poor predictor for @entity131 in the high BAC group. Readmission occurred in 22.4% (33) of @entity1 the BAC >= 400 group. The majority of these @entity1 reported drinking @entity285 4 or more days per week (81, 67.5%) and five or more drinks per day (79, 65.8%), evident of risky @entity285 use. CONCLUSIONS: Most @entity130 admitted with BAC >= 400 mg/dL survived and their @entity130 were less severe than their less intoxicated and sober counterparts. They also had evidence for risky @entity285 use and nearly one-quarter returned to the @entity130 centre with another injury over the study period. Recognition of this highest BAC group presents an opportunity to provide focused care for their risky @entity285 use.
