CLINICAL CHARACTERISTICS OF PATIENTS WITH TYPE 2 DIABETES MELLITUS CONTINUED ON ORAL ANTIDIABETES MEDICATIONS IN THE...

Basal/basal-bolus insulin with discontinuation of home oral antidiabetes medications (OADs) is the preferred method to achieve glycemic control in many hospitalized patients. We hypothesized that a subset of patients with type 2 diabetes mellitus (T2DM) can achieve an acceptable level of blood sugar control without cessation of their OADs when hospitalized. A retrospective chart review was conducted on patients with T2DM who were only on OADs at home, admitted to Fairview Hospital, a community hospital in the Cleveland Clinic Health System. We divided patients into those whose OADs were continued (group 1) and those whose OADs were discontinued (group 2), with or without the addition of insulin in the hospital. Blood glucose (BG) levels and patient characteristics were compared. There were 175 patients, 73 in group 1 and 102 in group 2. The percentage of patients achieving all BG values within 100 to 180 mg/dL was the same between group 1 (21.9%) and group 2 (23.8%) (P = .78). Mean BG was similar between group 1 and group 2 (146.1 ± 41.4 mg/dL versus 152.1 ± 38.9 mg/dL; P = .33), with no significant difference in terms of percentage of patients with hyperglycemia or hypoglycemia. A greater proportion of patients in group 1 had an uninterrupted feeding status, nonintensive care unit admission and no contrast dye exposure, and a shorter length of stay. Our study shows that patients with certain characteristics could achieve an acceptable level of glycemic control without cessation of their home OADs. Abbreviations: BG = blood glucose; DPP-4 = dipeptidyl dipeptidase 4; GFR = glomerular filtration rate; HbA1c = hemoglobin A1c; ICU = intensive care unit; LOS = length of stay; NPO = nil per os; OAD = oral antidiabetes medication; POC = point of care; T2DM = type 2 diabetes mellitus.
