Outcomes among XXXX discharged from the emergency department with a diagnosis of peripheral vertigo.

@entity1 @entity64 @entity174 @entity1897 @entity130
OBJECTIVE: We aimed to determine the risk of short- and long-term @entity64 , as well as @entity130 , in @entity1 discharged from an emergency department who were given a diagnosis of a @entity1897 . METHODS: In this population-based retrospective cohort study we identified all adult @entity1 who were discharged from an emergency department in Ontario, Canada, between 2006 and 2011, with a primary diagnosis of a @entity1897 . We assessed hospitalized @entity64 at 7, 30, 90, and 365 days, as well as subsequent falls, motor vehicle accidents, @entity174 , and burns. To provide context, we assessed the same outcomes in propensity score-matched discharged emergency department @entity1 with renal colic. RESULTS: Among 41,794 qualifying @entity1 , 76 (0.18%) had a @entity64 within 30 days. @entity130 at 30 days ranged from 0.01% (falls) to 0.15% ( @entity174 ). The relative risk (RR) of 30-day @entity64 was 9.3 (95% CI, 4.3-20.3) times higher than among matched renal colic controls. The RR was highest at 7 days (50.0; 95% CI, 6.9-362.0) and diminished with duration from the emergency department visit: RR 6.1 (95% CI, 3.5-10.7) at 90 days and 2.5 (95% CI 1.8-3.5) at 1 year. There was no difference in the risk of @entity130 . INTERPRETATION: The frequency of @entity64 following discharge from an emergency department with a diagnosis of a @entity1897 was extremely low. However the relative risk was markedly higher than in matched @entity1 with renal colic, suggesting that some @entity64 , or sentinel events for @entity64 , are being misdiagnosed as @entity1897 .
