Abstract: We evaluated the use of an updated version of the Guideline Interchange Format(GLIF), GLIF3, in the translation of clinical guidelines into an electronically encoded form. The goal of GLIF3 is to enable the effective sharing of such guidelines among various clinical institutions and settings. The newer version of GLIF was developed in response to limitations in the expressiveness of the earlier version, GLIF2. We videotaped and analyzed the encoding of two clinical guidelines both into GLIF3 and into GLIF2 by two medical informaticians. GLIF3 was found to be more robust than GLIF2 for representing the content and logical structure of the clinical guidelines studied. Our formative evaluation demonstrated that GLIF3’s intended improvements in expressiveness were achieved.
