Chapter 10 - Editing KCs during Execution

The clinical arena has the penchant for the unexpected. Therefore, no guideline, however well crafted, can be expected to deal with everything that can happen. Fortunately, the KCs are modular and therefore even within a guideline while one KC is executing another may be edited. Even more useful is the ability to drop a new KC into a guideline while it is executing. Say, while the patient is being investigated for menorrhagia, if you suspect that she has diabetes, it can be of great value to be able to drop a diabetes KC in the guideline, even while other investigations are in progress, and continue. Proteus and Protean allows for such editing during execution.

• With the Menorrhagia guideline loaded in Protean, execute the guideline by clicking on the [Run] button. When one of the AKCs is active, find the Process KC “Short OGTT”, in the PPC library tree and drag it on the active Process KC “History (Symptoms suggestive of other Pathology?)”, somewhere on the right side of the Atomic KC “Risk factors for endometrial ca?”, and drop it. You will notice the OGTT PKC appearing in the History PKC.
• Link the History AKC with the newly inserted OGTT PKC, using a sequential PAL. Now continue the execution of guideline by entering data in the already open AKC dialog. You will note that when the execution of Risk Factors AKC is complete, the OGTT PKC is triggered.
