BackgroundDevelopment of hyperglycemia during hospitalization is an area of concern in patients with and without diabetes mellitus. Tight glycemic control has been debated for critically ill and noncritically ill patients with hyperglycemia. Although many studies have been performed in the critically ill, adequate data are not available in the noncritically ill population.ObjectiveTo compare traditional sliding scale (SS) with a tight glycemic control (TC) algorithm. The primary endpoint was the percentage of total blood glucose measurements in the target range of 80-150 mg/dL. The secondary endpoint evaluated was safety, defined as percentage of all blood glucose measurements that were 0-60 mg/dL.MethodsA 1-year, retrospective analysis from June 1, 2007, to May 31, 2008, was performed evaluating all inpatients with hyperglycemia within the first 48 hours of admission to the Medical Center of Plano, Plano, TX. A cohort of patients managed with SS (n =121) was compared with those treated with TC (n = 210). Patients on SS insulin received a traditional SS regimen with regular insulin or insulin aspart based on physician preference.ResultsDemographics and comorbidities were similar between the 2 groups; however, the TC cohort was younger (64.8 + or - 14.1 vs 70.8 + or - 13.7 y; p < 0.001). There were more persons with type 2 diabetes mellitus in the TC cohort (81.9%) versus the SS cohort (60.3%; p < 0.001). In the TC cohort, 42.9% of blood glucose measurements were in the target range of 80-150 mg/dL compared with 30.6% of the measurements in the SS cohort (p < 0.001). Regarding safety, 2% of blood glucose measurements of the TC cohort were in the range of 0-60 mg/dL versus 0.3% of the SS cohort (p < 0.001). No clinical sequelae of hypoglycemia were observed. Patients achieved more blood glucose measurements in the target range when treated with TC versus SS insulin, without regard to prior history of diabetes.ConclusionsPatients treated with TC experienced more blood glucose measurements in the target range as compared with patients treated with SS with relatively low hypoglycemia rates.
