Welcome to the GRIP glucose site

ZISWatch added to this site! (March 2, 2008)

As a spin-off of the GRIP project, we made a program that monitors patients for extreme glucose values, and sends out mails when these events happen. This program was also successfully applied to monitor patients with nonseminoma testicular cancer for new b-HCG, AFP, and LDH values.
We have released the source code for the "nonseminomawatch" in a separate jar file from the GRIP distribution. The source code depends on classes found in the grip .jar file, and needs a proper implementation of AbstractHIS, the class that implements communication with the Hospital Information System.
The ziswatch source package can be directly downloaded here.

GRIP released!

After we had to delay the release of GRIP as open source longer than we anticipated, we are happy that we have approval to do so! Look on the Download page for more information.

View a preview of GRIP in demo-mode as a java web start application (java version 5 or higher needs to be installed, get it here!). Start the demo now or visit this page for more information.

What is GRIP?

GRIP (Glucose Regulation for Intensive care Patients) is a computer program that monitors blood glucose in the intensive care unit. The program uses blood glucose values and other clinical information to advise nurses on how much insulin should be administered and how often glucose should be sampled. For more background about the importance of glucose control in critically ill patients, see the background page.
For a more visual introduction, see the screenshot section.


Blood glucose control is a potentially life-saving intervention in critically ill patients. However, performing safe, tight glucose control requires a large amount of effort. Hypoglycemia (too low blood glucose levels) must be avoided, and therefore glucose needs to be sampled often. After every glucose measurement, a decision what to do has to be taken. We hypothesized that a computerized clinical decision support system is suitable for this task. See the GRIP as a CDSS section for more information.

Who is behind GRIP

Mathijs Vogelzang and Maarten Nijsten initiated the development of GRIP in the beginning of 2003 at the University Medical Center Groningen, part of the University of Groningen, the Netherlands. Since the beginning of 2005, it has been giving its advice for all patients in the Surgical ICU of the hospital. There's an official GRIP page at the umcg site (currently only Dutch): GRIP glucose control at the UMCG website.
