Blogs, Wikis, and Discussion Forums: Attributes and Implications for Clinical Information Systems

Informaticians increasingly view clinical information systems as asynchronous communication systems instead of data processing tools. Outside of health care, popular web technologies like blogs, wikis, and discussion forums have proven to be platforms for effective asynchronous communication. These popular technologies have implications for improving the coordination of clinical care and social support. In order to appropriately evaluate these webbased tools for use in clinical information systems, it will be essential for the informatics community to formally identify the distinguishing attributes of these communication methodologies. The authors propose seven interpersonal and informational attributes to compare and contrast the purposes of blogs, wikis, and discussion forums. This attribute-based approach to analyzing emerging web technologies will lead to a better understanding of the design choices involved in web-based information systems. Two case studies demonstrate how informatics researchers and developers can consider these attributes in the design and evaluation of clinical information systems.
