Glycemic control outcomes of manual and computerized insulin titration protocols: a systematic review protocol

The object of this systematic review is to determine the effectiveness of computerized insulin titration protocols compared to manual insulin titration protocols for glycemic control in hospitalized adult patients.

Hyperglycemia is common during acute illness, and current recommendations for patients with altered glucose metabolism is the use of intravenous insulin therapy. Due to the narrow therapeutic index of insulin, euglycemia is difficult to achieve and requires frequent dose titrations and blood glucose checks. Dose titrations can be accomplished through the use of manual or computerized insulin titration protocols.

This review will consider studies that compare manual and computerized insulin titration protocols for hospitalized adult patients requiring intravenous insulin therapy for hyperglycemia. Studies must have considered one or more glycemic control outcomes.

This systematic review will use the JBI methodology for evidence of effectiveness. The search will be limited to studies published in English from 1984, as this was the approximate year that the first pilot study of a computerized titration protocol was implemented. The databases to be searched include: Cochrane Central Register of Controlled Trials, CINAHL, PubMed, Embase, Health Technology Assessments and Ovid Healthstar. The trial registers to be searched include: US National Library of Medicine (ClinicalTrials.gov). The search for unpublished studies will include ProQuest Dissertations and Theses, and MedNar. Retrieval of full-text studies, assessment of methodological quality and data extraction will be performed independently by two reviewers. Meta-analysis will be performed if possible, and a Grading of Recommendations, Assessment, Development and Evaluation (GRADE) Summary of Findings presented.
