Designing the E-Health Message
The tremendous growth in the use of Web 2.0 technologies, interactive computer technologies, electronic records, and mobile devices for delivery of e-health necessitates attention to design. Designing e-health requires consideration of research, including best practices embodied in design principles. This chapter reviews key background information, including central definitions, concepts, and research, followed by a presentation of 9 key considerations that are recommended for guiding the design of e-health messages. An illustrative case example demonstrates how a typology that codifies design principles gave rise to a research tool that permits the evaluation of health care websites. The case example underscores the important role of findings from research evaluations in creating a feedback loop for designers, permitting research to inform refinements in design. Overall, the 9 key considerations suggest a new paradigm for design, while also giving rise to corresponding recommendations for future research to support evolution in the field of e-health.
