Abstract

The construct of value is highly relevant to information. For research on the value of information, Saracevic and Kantor (1997) proposed a framework from a value perspective in philosophy. In this report, we substantiate the framework with an updated review of the literature and demonstrate its applicability to understanding the value of user feedback as one type of information. Our field study, in the setting of a health information provider whose information products serve thousands of Canadian healthcare professionals, provides an example of how this value-of-information framework can be operationalized for an organization. In addition to the theoretical and methodological contributions, this research adds to the literature by documenting the way that textual feedback data were used to optimize the content of an information resource. This contrasts with published studies that only dealt with the use of quantitative feedback by information providers not involved in content production.

Abstract

Inspired by the acquisition-cognition-application model (T. Saracevic & K.B. Kantor, 1997), we developed a tool called the Information Assessment Method to more clearly understand how physicians use clinical information. In primary healthcare, we conducted a naturalistic and longitudinal study of searches for clinical information. Forty-one family physicians received a handheld computer with the Information Assessment Method linked to one commercial electronic knowledge resource. Over an average of 320 days, 83% of 2,131 searches for clinical information were rated using the Information Assessment Method. Searches to address a clinical question, as well as the retrieval of relevant clinical information, were positively associated with the use of that information for a specific patient. Searches done out of curiosity were negatively associated with the use of clinical information. We found significant associations between specific types of cognitive impact and information use for a specific patient. For example, when the physician reported "My practice was changed and improved" as a result of this clinical information, the odds that information was used for a specific patient increased threefold. Our findings provide empirical data to support the applicability of the acquisition-cognition-application model, as operationalized through the Information Assessment Method, in primary healthcare. Capturing the use of research-based information in medicine opens the door to further study of the relationships between clinical information and health outcomes.
