OBJECTIVE: To provide an overview of the use and impact of written drug information (WDI) on consumers, and to review the literature on the factors influencing the use of WDI by consumers.
DATA SOURCES: Relevant articles published in English since the late 1970s were identified based on searches of on-line databases, texts, and cited references in published articles.
STUDY SELECTION: Articles reporting findings on the origin, use, and impact of WDI were included. Due to limited literature, articles reporting findings on factors influencing the use of written drug as well as disease information were included.
DATA EXTRACTION: Due to the lack of design consistency between studies and the comparatively small volume of work, subjective assessment rather than a criteria-based objective review was deemed more appropriate.
DATA SYNTHESIS: To date, research on WDI has focused on its use and impact. WDI has the potential to increase patients' knowledge, compliance, and satisfaction. However, there is also the potential for anxiety or premature cessation of therapy due to fear of possible adverse effects. Multiple factors may potentially influence the use of WDI by consumers including those associated with the written information document (readability, presentation), the patient (health literacy, role of caregiver, demographic factors, health locus of control, coping style, health belief model), and the environment (timing of provision, experience).
CONCLUSIONS: WDI has the potential to impact consumers positively and negatively. Although not widely investigated, a number of factors can potentially influence the use of WDI by consumers. The findings of this review can form the basis for much needed further research.
