Objective: The primary aim of this study was to explore the use of clinical knowledge sources among junior doctors in relation to their learning styles. The secondary aim was to describe how junior doctors value different qualities of knowledge sources in clinical situations. Methods: A cross-sectional study among 63 junior doctors in a Swedish hospital. A questionnaire was used to collect information about the use of knowledge sources, to identify learning styles according to Kolb and to record the value of qualities of knowledge sources in clinical situations. The 1-Sample Sign Test and the Mann-Whitney test were used to analyse the non-parametric data. Results: The most frequently used knowledge sources were personal contacts with colleagues (n=14, p=0.0002) followed by internet-based guidelines (n=14, p=0.0034) and printed reference literature (n=14, p=0.0225). Learning styles aggregated into two main clusters, converging (54%) and assimilating (30%). Access was the most valued quality of knowledge sources. Conclusions: Although personal contacts were most frequently used, internet-based sources reached almost the same level. Learning styles among junior doctors were in accordance with the findings in previous studies. Convergers seemed to use computer-based knowledge sources less than the assimilators. This needs further investigation. Access should be addressed in the design of knowledge tools since this was overall the most valued quality in clinical situations.
