Nurse-Directed Blood Glucose Management in a Medical Intensive Care Unit

Crit Care Nurse. 2017 Jun;37(3):30-40. doi: 10.4037/ccn2017922.

Abstract

Background: Insulin-delivery algorithms for achieving glycemic control in the intensive care unit require frequent checks of blood glucose level and thus increase nursing workload. Hypoglycemia is a serious complication associated with intensive insulin therapy.

Objectives: To evaluate a nurse-directed protocol for blood glucose management that allows individualized insulin delivery within a predefined blood glucose corridor, intended to avoid hypoglycemia while maintaining adequate control of blood glucose level without increasing nursing workload.

Methods: A nurse-directed protocol for blood glucose management was developed by an interprofessional team, and the protocol's performance was investigated in 175 patients compared with 384 historical controls.

Results: With the nurse-directed protocol, hypoglycemia incidents declined significantly (31% vs 12%, P < .001), and minimum blood glucose levels increased significantly (80 mg/dL vs 93 mg/dL, P < .001). Mean and maximum blood glucose levels, the proportion of glucose readings within the target range (31% vs 26%, P = .06), and the number of blood glucose checks (59 vs 58, P = .85) remained unchanged with use of the protocol.

Conclusion: Implementation of the nurse-directed protocol for blood glucose management did not increase nursing workload but reduced hypoglycemia incidents significantly while maintaining adequate glycemic control.
