BACKGROUND: @entity295 has a high prevalence, mortality-rate and cost. @entity295 @entity1 usually enter the hospital through the @entity341 ( @entity341 ). Process or structural issues related to care may affect outcome. METHODS: Multi-centered retrospective observational cohort study using administrative databases to identify adult @entity1 (>   =   18  years) with @entity295 and @entity295 admitted to Alberta Health Services Calgary zone adult multisystem @entity1213 ( @entity1213 ) through the @entity341 between January 1, 2006 and September 30, 2009. We examined the association between @entity1213 occupancy and hospital outcome. We explored other associations of hospital outcome including the effect of @entity341 wait time, admission from @entity341 during weekdays versus weekends and @entity341 admission during the day versus at night. RESULTS: One thousand and seven hundred seventy @entity1 were admitted to hospital via @entity341 , 1036 (58.5  %) with @entity295 and 734 (41.5  %) with @entity295 . In @entity1 with @entity295 , @entity1213 occupancy   >   90  % was associated with an increase in hospital mortality even after adjusting for age, sex, triage level, Charlson index, time of first @entity341 physician assessment and @entity1213 admission. No differences in hospital mortality were found for @entity1 who waited more than 7  h, were admitted during the day versus night or weekdays versus weekends. CONCLUSIONS: In @entity1 with @entity295 admitted via the @entity341 , increased @entity1213 occupancy was associated with higher in-hospital mortality.
