BACKGROUND: In March 2008, the University of California, Davis Medical Center(UCDMC), implemented a guideline for the inpatient management of diabetes in noncritically ill adults. In accordance with national guidelines, all patients with type 2 diabetes are prescribed basal, nutritional, and correctional insulin. The guideline was added to the electronic medical record as a standardized physician order set in April 2008 and provider training on the insulin guideline occurred in May 2008. OBJECTIVE: To evaluate provider compliance with a new electronic standardized insulin order set in a hospital setting. METHODS: All patients with insulin orders admitted to the general internal medicine service between June 1, 2008, and November 1, 2008, were evaluated in this single-center retrospective chart review at UCDMC in Sacramento. Patients older than 18 years with a history of type 2 diabetes were included in the analysis. Insulin orders were categorized as preferred (followed the guideline) or nonpreferred regimens (did not follow all components of the guideline). RESULTS: A total of 265 patients were identified during the study period. The preferred regimen was ordered in 82 (30.9%) of the evaluated patient admissions. Of the 183 (69.1%) nonpreferred regimens, more than half (54.6%) contained correctional insulin alone; 84.2% of patient admissions prescribed nonpreferred regimens lacked nutritional insulin. Average admission blood glucose readings were higher in the preferred versus nonpreferred regimen group (224.4 vs 164.8 mg/dL, p < 0.001). CONCLUSIONS: The preferred regimen was not prescribed for the majority of patients admitted with a history of type 2 diabetes, despite computerized decision support. Nutritional insulin was the most common missing component in the nonpreferred regimens. Baseline clinical factors, educational modalities, and guideline content may have influenced prescribing patterns.
