Relationship of Glucose Values to Sliding Scale Insulin (Correctional Insulin) Dose Delivery and Meal Time in Acute Care Patients with Diabetes Mellitus

Introduction
Managing blood glucose (BG) level in diabetic patients proves to be a challenging goal to insulin. The stand-alone method in many adult acute setting is the use of sliding scale insulin (SSI) to treat hyperglycemia. The goal within these settings is to maintain the BG level below 180 mg/dl (Trotter, Conaway & Burns, 2008).
The researcher

PCA’s blood glucose levels were higher in the morning and the afternoon than those obtained by the nurse. Morning and afternoon activities showed a consistent variable in; time- lapse between the nurse’s and PCA’s finger stick glucose values; SSI dose based on nurse’s BG values obtained later and the time patient received meals post SSI dose. These findings supported the literature review that SSI dose should be given 30 minutes before meals to anticipate the insulin peak for the prevention of hyperglycemia post prandial.
Findings/Interpretation of Findings One limitation of the study was that it did not include BG results for the evening dosing of insulin. Those results would have helped to support the continued trend seen in higher BG readings when insulin was not given 30 minutes prior to the consumption of meals. SSI dose administered 30 minutes prior to mealtime allows the peak action of insulin to combat the rise in BG from the meal consumed. It did however, consistently showed a deviation in time-lapse in obtaining BG results obtained by PCA’s and nurses (lower values) and the decrease in SSI dose based on nurse’s BG values. The SSI dose given would (at least 1 unit lower), reflecting an inappropriate management of blood glucose levels.
This study provided an unbiased finding. Data was carefully collected and staff nurses on the selected units were
