Undiagnosed Diabetes in Patients Admitted to a Clinical Decision Unit from the Emergency Department: A Retrospective...

Objectives Diabetes is a debilitating disease that affects the way the body uses or produces insulin. Research evaluating the usefulness in screening patients admitted to a clinical decision unit (CDU) from the emergency department (ED) has been limited. Methods A retrospective chart review of patients admitted to a CDU from the ED was performed. Patients included were > 18-year-old who were observed in the CDU, had blood glucose drawn greater than eight hours after admission, and who had not been previously diagnosed with diabetes. Age, sex, and fasting glucose level were collected. The analysis was done to evaluate the percentage of patients undiagnosed and at risk for diabetes mellitus by assessing fasting blood glucose the morning after admission. Results Study revealed that 27.8% of the patients analyzed in this study had fasting blood glucose levels meeting or exceeding the diagnostic threshold of 126 mg/dL and could potentially have undiagnosed diabetes. Conclusion Screening patients admitted to a CDU from the emergency department identified that 27.8% had fasting plasma glucose levels ≥ 126 mg/dL. Consideration should be made to obtain a fasting blood glucose level in those without a previous diagnosis of diabetes who are observed overnight in a CDU.
