Effect of A Computerized Insulin Dose Calculator On the Process of Glycemic Control

Case Study


Glycemic control is important to patients’ outcomes. However, the process of maintaining glycemic control is risk laden and labor intensive for nurses.


To examine the effects of using a computerized insulin dose calculator to facilitate management of glycemic control for critically ill cardiac patients.


Management of glycemic control and nurse satisfaction were improved with use of the dose calculator. Improving nurses’ processes of care may improve nurses’ use of time and patient care overall. Studies with larger sample sizes over time are needed to determine these relationships.


Improving Process – Improving Care

Glucose Levels in Target

A significantly higher percentage of glucose measurements were in the target range in the calculator group than the control group (70.4% vs 61.6%), and glucose variance was significantly less in the calculator group (35.5 mg/dL vs 42.3 mg/dL).

Fewer Hypoglycemic Events

Fewer hypoglycemic events occurred in the calculator group (7 vs 18).

Greater Nurse Satisfaction

Nurse satisfaction was higher for the calculator group than for the control group (8.4 vs 4.8). Nurses’ deviation from the protocol was also less in the calculator group than in the control group.
