The purpose of the study was to test the impact of care coordinator visits by primary care registered nurses on serum hemoglobin A1c (HbA1c) levels in patients with type 2 diabetes. In the study, the researcher compared 2 groups of type 2 diabetes patients—those who had care coordinator visits from registered nurses and those who did not—through retrospective data collection and analysis from the patients’ electronic medical record from July 2018 through December 2018. An independent samples t test was used to compare the means of the intervention and control groups’ change in HbA1c levels. The intervention and control groups did not differ in baseline HbA1c levels. Gender and age did not have a major impact on change in HbA1c levels. Change in HbA1c levels ranged from a decrease of 4.20 to 0 for the intervention group and a decrease of 1.20 to an increase of 2.10 for the control group. The intervention and control groups differed significantly in change in HbA1c levels, p < .0001. The study results strongly demonstrated that registered nurse care coordination had a positive effect on HbA1c levels for type 2 diabetic patients in primary care.
