Researchers from Columbia University School of Nursing Detail Findings in Medical Informatics (The impact of home care nurses' numeracy and graph literacy on comprehension of visual display information: implications for dashboard design)
By a News Reporter-Staff News Editor at Information Technology Newsweekly Current study results on Information Technology - Medical Informatics have been published. According to news reporting from New York City, New York, by VerticalNews journalists, research stated, "To explore home care nurses' numeracy and graph literacy and their relationship to comprehension of visualized data. A multifactorial experimental design using online survey software."
Financial support for this research came from Agency for Healthcare Research and Quality.
The news correspondents obtained a quote from the research from the Columbia University School of Nursing, "Nurses were recruited from 2 Medicare-certified home health agencies. Numeracy and graph literacy were measured using validated scales. Nurses were randomized to 1 of 4 experimental conditions. Each condition displayed data for 1 of 4 quality indicators, in 1 of 4 different visualized formats (bar graph, line graph, spider graph, table). A mixed linear model measured the impact of numeracy, graph literacy, and display format on data understanding. In all, 195 nurses took part in the study. They were slightly more numerate and graph literate than the general population. Overall, nurses understood information presented in bar graphs most easily (88% correct), followed by tables (81% correct), line graphs (77% correct), and spider graphs (41% correct). Individuals with low numeracy and low graph literacy had poorer comprehension of information displayed across all formats. High graph literacy appeared to enhance comprehension of data regardless of numeracy capabilities. Clinical dashboards are increasingly used to provide information to clinicians in visualized format, under the assumption that visual display reduces cognitive workload. Results of this study suggest that nurses' comprehension of visualized information is influenced by their numeracy, graph literacy, and the display format of the data."
According to the news reporters, the research concluded: "Individual differences in numeracy and graph literacy skills need to be taken into account when designing dashboard technology."
