Abstract
OBJECTIVE: To determine whether blood test results lead to a change in planned disposition of patients from the ED. METHODS: A prospective review of the anticipated and actual disposition of patients from the ED before and after blood test results, including stratification by seniority of medical staff. RESULTS: There were 256 patients enrolled, 53% had blood tests requested. Expected disposition was not altered by test results in 87% of patients having blood tests. Medical staff were poor at identifying those patients whose disposition would be altered by their blood results (sensitivity 44%, specificity 72%, negative predictive value 89%). Seniority of medical staff was not associated with an alteration in disposition due to the blood results (P = 0.37). CONCLUSIONS: Blood test results have minimal impact on expected patient disposition from the ED. Recognition of this may improve resource utilisation with earlier discharge planning.
