Newly identified hyperglycemia among hospitalized patients.

Background: Earlier diagnosis and treatment of diabetes mellitus is desirable. We studied the prevalence of newly identified diabetes among hospital inpatients. Methods: We did a prospective observational study in a community teaching hospital. Results: Thirty-six patients had hyperglycemia on at least 2 days and were considered to have newly identified diabetes mellitus. They represented approximately 1% of the inpatient population. Sixteen (44%) were receiving corticosteroid treatment. Five of the patients (14%) died during the hospitalization. Twenty-four (67%) received insulin treatment during hospitalization. Of the 31 surviving patients, only 15 (48%) had documentation of discharge plans for diabetes-related treatment, 7 (23%) received instruction by a dietitian, and 5 (16%) received education about diabetes self-management from a diabetes nurse educator. Conclusion: Hospitalized patients with newly identified hyperglycemia represent an opportunity for early diagnosis, education, and treatment of a substantial proportion of patients with undiagnosed diabetes.
