Exceptions handling within GLARE clinical guideline framework.

Computerized clinical guidelines (CIGs) are widely adopted in order to assist practitioner and patient decision making. However, a main problem in their adoption is the fact that, during guidelines executions on specific patients, unpredictable facts and conditions (henceforth called exceptions) may occur. A proper and immediate treatment of such exception is necessary, but most current software systems coping with CIGs do not support it.
