Task performance using the HIS. Change in ease of performing individual tasks for each profession when using the HIS. The tasks appear in the same sequence as that of figure 3, i.e. the frequency with which the HIS is used for the task. The responses indicating a task to be easier to perform appear in blue tones, and those indicating it to be more difficult appear in red. The error bars show the confidence interval of the proportion of respondents answering "Significantly increased". For definitions of the individual tasks, see appendix A. (The data for the physicians[4] is included for comparison)
