OBJECTIVE: To ascertain the differences among hospitals in Japan in the management patterns and outcomes of @entity1 with @entity583 ( @entity583 ). DESIGN: Retrospective cohort study by means of @entity1 chart review. SETTING: Four tertiary-care teaching hospitals in Japan observed over a 1-year period. STUDY @entity1 : Consecutive @entity1 (N=482) admitted for @entity583 . MAIN OUTCOME MEASURES: Clinical characteristics, rates of diagnostic and therapeutic procedures performed, @entity299 , and length of stay. RESULTS: @entity1 ' clinical characteristics differed significantly among the four hospitals in terms of age, gender, and prior cardiac history, but not in terms of comorbidity or @entity1188 location. The frequency and type of diagnostic and therapeutic procedures were different, and in-hospital mortality varied (4-14%, P=0.022). Average length of hospital stay ranged from 15.8+/-12.6 days to 41.0+/-19.4 days (P=0.0001). After adjustment for the clinical characteristics, these differences remained significant among hospitals. CONCLUSION: Considerable differences in the management and outcomes of @entity1 with @entity583 exist in Japan.

Differences in management and outcomes of XXXX among four general hospitals in Japan.
