Successful Implementation of a Perioperative Glycemic Control Protocol in Cardiac Surgery : Barrier Analysis and Intervention Using Lean Six Sigma

Abstract EN

Although the evidence strongly supports perioperative glycemic control among cardiac surgical patients, there is scant literature to describe the practical application of such a protocol in the complex ICU environment.

This paper describes the use of the Lean Six Sigma methodology to implement a perioperative insulin protocol in a cardiac surgical intensive care unit (CSICU) in a large academic hospital.

A preintervention chart audit revealed that fewer than 10% of patients were admitted to the CSICU with glucose <200 mg/dL, prompting the initiation of the quality improvement project.

Following protocol implementation, more than 90% of patients were admitted with a glucose <200 mg/dL.

Key elements to success include barrier analysis and intervention, provider education, and broadening the project scope to address the intraoperative period.
