    Society for Academic Emergency Medicine Annual Meeting. Washington, DC, USA, 1997/05.

    Study objectives 

    To identify diagnostic predictors of return emergency department visits, and to compare actual and perceived associations between initial ED diagnosis and revisits to help identify target diagnoses for prevention strategies.


    This 2-part study involved a retrospective observational study and a health professional survey.

    The study population consisted of all patients with 2 or more visits to the University of Michigan ED within a 3-day period between July 1995 and June 1996 ( « early-return visitors »). Billing records identified the initial diagnoses of subsequent return visitors.

    The prevalence of each initial diagnosis was determined in the general ED population (n=52,553), early-return population (n=1,422), and early-return population admitted to the hospital ( « return-admit, » n=313).

    Surveys were distributed to all ED health professionals to assess their perception of the diagnoses most likely to return within 3 days.

    Relative risk (RR) ratios and 95% confidence intervals (Cls) were calculated.


    Dehydration was the most common diagnosis in the general, early-return, and return-admit populations (prevalence : 7%, 15%, 25%, respectively).

    Dehydration was also the diagnosis with the highest risk for both early return and subsequent admission on early return (RR [95% Cl] : 2.3 [2.0-2.6], 1.8 [1.5-2.3], respectively). (...)
