Hyperglycemia in ED patients with no history of diabetes

Introduction

The purpose of this study was to determine the prevalence of incidentally discovered hyperglycemia in patients with non–glucose-related complaints and to consider the potential care implications.

Methods

A retrospective chart review identified patients older than 18 years with obtained serum glucose levels. Patients with diabetic ketoacidosis were excluded. Three levels of hyperglycemia (≥126, ≥140, and ≥200 mg/dL) were considered.

Results

Of 2473 adult patients, 290 patients (11.7%) had serum glucose values greater than or equal to 126 mg/dL. There were 154 patients with hyperglycemia and no prior history of diabetes (6.2% of the emergency department ED] population, 53.1% of those with hyperglycemia).

Conclusion

More than half of the patients found to be hyperglycemic had no known history of diabetes and were being seen for a non–glucose-related complaint. The reason for this prevalence and its impact on the health of these patients is unclear. Whether ED intervention would be helpful remains unanswered.
