Abstract
In this paper we aim to discuss a theoretical explanation for the positive relationship between patients' knowledge and their trust in healthcare personnel. Our approach is based on John Dewey's notion of continuity. This notion entails that the individual's experiences are interpreted as interrelated to each other, and that knowledge is related to future experience, not merely a record of the past. Furthermore, we apply Niklas Luhmann's theory on trust as a way of reducing complexity and enabling action. Anthony Giddens' description and analysis of the high modern society provides a frame for discussing the preconditions for patient-healthcare personnel interaction. High modernity is dominated by expert systems and demands trust in these. We conclude that patient knowledge and trust in healthcare personnel is related because both knowledge and trust are future- and action-oriented concepts. The traits of high modernity provides opportunities and challenges as the personnel can and must perform discretion. This discretion must be made in a context where knowledge is considered uncertain and preliminary.
