@entity1 @entity1576 @entity55
OBJECTIVE: @entity55 ( @entity55 ) is a new @entity55 . We investigated differences of epidemiology, pathogens, and outcomes between @entity55 @entity1 in large hospitals and those in small hospitals. METHODS: This was a retrospective observational study of @entity1 hospitalized with @entity55 from December 2009 to March 2010. @entity55 was defined according to ATS/IDSA criteria. A large hospital was defined as >=  200 beds and a small hospital was <200 beds. RESULTS: Of 117 @entity1 , 61 @entity1 were admitted to large hospitals and 56 @entity1 were admitted to small hospitals. There was a significant difference of @entity55 diagnostic criteria between the two groups. The A-DROP severity class was worse in the large hospital group than the small hospital group (P<0.05). @entity1576 and disturbance of consciousness were more frequent in the large hospital group (P<0.05). The mortality rate was 8.2% in the large hospital group versus 1.8% in the small hospital group. @entity1 in the very severe A-DROP class had a high mortality rate of 33% in both groups. CONCLUSION: @entity1 with severe @entity55 were more likely to be admitted to large hospitals. @entity1 in the very severe A-DROP class should receive intensive antibiotic therapy, but not all @entity1 need broad-spectrum therapy.
