title: Use of beta-hydroxybutyric acid levels in the emergency department.
abstract: The impact of a new test on the market, the beta-hydroxybutyric acid (BOH) assay, on clinical decision-making in the emergency department (ED) has not been well studied. In this retrospective analysis, we studied the potential benefit of this new test in the ED decision-making process in diabetic patients. BOH levels were measured on all patients who had glucose and acetone levels ordered by the emergency physician during a 3-month period in the ED of a university tertiary referral center. Two groups were analyzed: group 1 was acetone-positive and BOH-positive (n = 13); group 2 was acetone-negative BOH-positive (n = 31). There was no difference between the two groups in terms of gender (p = 0.55) or age (p = 0. 47). The length of stay (p = 0.97) and number of complications (p = 0.89) were also similar between the two groups.
  
  
  CONCLUSIONS
  This study suggests that in those diabetic patients with a negative acetone test and a positive BOH test, the addition of the positive result on the BOH test may provide additional prognostic information for predicting hospital length of stay and number of in-hospital complications.
