Impact of electronic health record clinical decision support on diabetes care: a randomized trial
Ths is an atricle review of O’Connor, P. J., Sperl-Hillen, J. M., Rush, W. A., Johnson, P. E., Amundson, G. H., Asche, S. E., ... & Gilmer, T. P. (2011). Impact of electronic health record clinical decision support on diabetes care: a randomized trial. The Annals of Family Medicine, 9(1), 12-21. 
Primary-care providers deliver majority (80%) of diabetes treatment and care. There is a need to improve strategies via Clinical decision support systems (CDSS) in primary-care settings to address control of A1c levels, blood pressure, and LDL cholesterol levels in adults living with diabetes.
This study used a randomized-control trial where patients either received or did not receive an electronic health record customized CDSS for patients with high A1c levels, blood pressure, and LDL cholesterol levels than anticipated.
The intervention group showed significantly better A1c levels [Interaction Effect -0.26%; 95% CI (-0.06,0.47); p=.01] and maintained systolic (80.2 % vs 75.1% control group; p=.03) & diastolic (85.6% vs 81.7% control group; p=.07) blood pressure control. However, the intervention group had lower LDL levels (p=.62) than the control group. User satisfaction of primary-care providers for intervention group were satisfied or very satisfied (94%) with the CDSS including feedback of moderate use a year after intervention.
Summary of ADA-Recommended Treatment Goals for Most Adults with Diabetes. 
- Blood Pressure - <130/180
- A1C - <7.0
- Total Cholesterol - <200
- Triglycerides (mg/d1) - <150
- HDL Cholesterol (mg/d1) - Women >50; Men >40
- LDL Cholesterol (mg/d1) - <100
- Controlled vs. Uncontrolled Diabetes – Controlled = A1C <7.0% / Uncontrolled = A1C > 7.0%
The use of this CDSS helped improve A1c levels and some aspects of blood pressure control in adults living with diabetes.
This article was interesting as it featured a CDSS for more than one measure of diabetes primary-care treatment. As an RCT, it contributed towards the literature and reinforced guidelines  for meeting certain levels of A1c, blood pressure, and LDL cholesterol for adults living with diabetes. Other studies have looked at the outcomes of glycemic control with Type 2 diabetes using clinical decision support as opposed to no access to clinical decision support.
