Abstract:
The objective of this review was to investigate process of pictograph development and the effectiveness of pictographs in patient education. We conducted searches in Medline/PubMed, CINAHL with full text, PsycInfo, ERIC and Cochrane Library with keywords: (pictograph or pictorial) AND (patient education) NOT (children or adolescent or youth or child or teenagers). After excluding manuscripts that did not meet inclusion criteria, 56 articles were included between the time of the last review on this topic (January 2008) and May 2019. There are 17 descriptive studies, 27 randomized control trial studies, 9 quasi-experimental studies and 2 unique literatures in the systematic review. Major goals of the studies are pictograph development or validation. The majority of manuscripts (n = 48) supported the approach. However, six studies did not find significant differences in the outcome. Differences in patient population, pictograph designs and author-developed outcome measurements made it difficult to compare the findings. There is a lack of evidence on validating information outcome measurements. This review demonstrated that implementing pictographs into patient education is a promising approach for better information understanding and health management. Pictographic interventions need to be carefully developed and validated with both the targeted patient population and the clinical experts.

The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
