Background Glucose Screen
•High glucose levels in cardiac patients are associated with Eight-bed display with five
adverse outcome admitted patients shown.
•Glucose regulation in patients admitted to the Intensive Empty beds are grey.
Cardiac Care Unit (ICCU) is difficult to achieve
•Implementation of a Clinical Decision Support System
Pop-up displays new glucose

To develop a CDSS to improve the glucose regulation of the information.
patients admitted to the ICCU. To evaluate shortcomings in
the glucose protocol with the CDSS.
Insulin dose is displayed by the
black marks.
Methods
Ajax-driven screen that uses a web service to update
•Retrospective analysis of 918 patients with 15360 glucose automatically. It displays the last lab values received from the
measurements during 18 months HIS and the pump standings from the replicated PDMS
•Development and implementation of a web 2.0-based CDSS database. Advice is generated by the web service for each
screen for glucose management new value.
•Evaluation of prospectively collected data from 187 patients
with 3418 glucose measurements during 4 months Discussion

Results Conclusion
Compliance with protocol regarding timing of glucose
•Implementation of a dedicated web based CDSS screen
measurements:
led to improved protocol compliance regarding two
•Increased from 41% to 55% on time, an increase of 13.2%
variables (time and dosage)
(95%CI 11.4% to 15.1% P<0.001)
•Future work is needed to expand the current program
Compliance with protocol regarding insulin dosage: with an enhanced protocol and a 3rd party protocol
•Increased from 48% to 58%, an increase of 9.8% (95% CI editor
