Inpatient management of type 2 Diabetes Mellitus: Does choice of insulin regimen really matter?

Objective: To assess inpatient management of non-critically ill type 2 diabetics with different insulin regimen. Methods: We reviewed the medical records of all non-critically ill type 2 diabetic patients more than 18 years of age in medical department of civil hospital Karachi and Dow University of Health Sciences from January 2011 to December 2012. We collected the data from case records in data collection sheets that fulfill the inclusion criteria and divided the study subjects into three groups according to insulin regimen they received. Results: A total of 416 patients were analyzed out of which 220 were male. Subjects were divided into three groups according to insulin regimen they received. Majority were put on sliding scale of insulin (44.7%), while 33.1% and 22.1% subjects received basal bolus and pre-mixed insulin regimen respectively. Patients treated with basal bolus regimen had greater improvement in glycaemic control with short duration of hospital stay as compared to other two groups. The mean hyperglycaemic events were higher in sliding scale group while mean hypoglycaemic events were higher in basal bolus group. Conclusion: In non-critically ill type 2 diabetic patients the basal bolus regimen is superior to sliding and pre-mixed insulin regimen. Sliding scale should be discouraged in non-critically ill type 2 diabetic patients.
