The extent and effects of patient involvement in pictogram design for written drug information: a short systematic review.

This short review provides insight into the extent and effectiveness of patient involvement in the design and evaluation of pictograms to support patient drug information. Pubmed, CINAHL, Cochrane Library, Embase, PsycINFO, Academic Search Premier and Web of Science were searched systematically; the 73 included articles were evaluated with the MMAT. We see that, usually, non-patient end-users are involved in the design of pharmaceutical pictograms - patients are more commonly involved in the final evaluation of pictogram success. Repeated involvement of (non-)patients aids the design of effective pharmaceutical pictograms, although there is limited evidence for such effects on patient perception of drug information or health behaviour.
