The purpose of this study was to determine what factors beyond relevance influence a clinician's decision to choose to read one journal article over another in satisfying an information need.
Seventeen health care providers were interviewed and then surveyed regarding the characteristics of key articles (those they would not want to miss). On a Likert scale, the clinicians graded forty-two characteristics for importance in the decision process. Relevance was assumed and not at issue.
The study took place in an academic health science center.
The subjects were seventeen clinicians, all with patient care responsibilities. There were four internists, four surgeons, three family practitioners, three pediatricians, two psychiatrists, and one clinical psychologist.
Factors beyond relevance that most often influenced the decision process pertained to methodological rigor, authors and their institutional affiliations, document types, and population studied.
Among the clinicians surveyed, factors beyond topicality influenced judgments as to what constitutes an important article. The emphasis respondents gave to certain attributes is echoed in other published work and highlights the need for more intensive investigation of these non-subject indicators as search parameters. Improved searching capabilities might well lead to a significant reduction in the clinician's information overload.
本研究旨在确定除相关性之外，还有哪些因素会影响临床医生在满足信息需求时选择阅读某一篇期刊文章而非另一篇的决定。
对17名医疗保健提供者进行了访谈，然后就关键文章（他们不想错过的文章）的特征进行了调查。临床医生采用李克特量表对决策过程中42个特征的重要性进行评分。假定相关性存在且不成问题。
该研究在一所学术健康科学中心进行。
受试者为17名临床医生，均负责患者护理工作。其中有4名内科医生、4名外科医生、3名家庭医生、3名儿科医生、2名精神科医生和1名临床心理学家。
除相关性之外，最常影响决策过程的因素涉及方法的严谨性、作者及其机构隶属关系、文献类型和所研究的人群。
在接受调查的临床医生中，除主题性之外的因素影响了对什么构成重要文章的判断。受访者对某些属性的重视在其他已发表的研究中也有体现，这突出了将这些非主题指标作为检索参数进行更深入研究的必要性。改进的检索功能很可能会显著减少临床医生的信息过载。
