Initial emergency department diagnosis and return visits : risk versus perception.
Society for Academic Emergency Medicine Annual Meeting. Washington, DC, USA, 1997/05.
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). (...)
