Class of 2011 Abstract / OBJECTIVES: To design and evaluate a dosing schedule pictogram in an elderly population. To identify possible reasons for misunderstanding of a dosing schedule pictogram and, if appropriate, redesign the pictogram to reflect reasons for misunderstanding.
METHODS: Through a modified focus group analysis involving residents of a retirement community in Tucson, Arizona, the understandability of a morning-noon-night color pictogram was assessed. Residents’ interpretation of the pictogram as correct or incorrect was assessed using a decision-tree analysis. The percentage of correct responses was calculated and compared to established pictogram criteria for acceptability. Lastly, potential reasons for misunderstanding were assessed.
RESULTS: Thirteen residents, six males and seven females, participated in the study. The rate of correct interpretation was 84.6%, which nearly satisfies the ANSI criterion of 85% correct and far exceeds the ISO criterion of 67% correct. Two participants incorrectly interpreted the pictogram, but their comments, however, indicated good comprehension of time of day.
CONCLUSION: The dosing schedule pictogram was correctly interpreted by a majority of study participants satisfying industry standards. Further analysis of this design is warranted.
