Developing a user-friendly format for automated reports on urinary catheters and catheter-associated urinary tract infections
Manual surveillance and reporting for both urinary catheter use and catheter-associated urinary tract infection (CAUTI) are time-consuming processes. Our goal was to develop a format for automated (computer-generated) CAUTI reports that would be comprehensible, useful, and trustworthy to providers engaged in CAUTI prevention.
This study employed iterative design, in which we showed a sample data report to potential end-users, surveyed them about usability, and then revised the report accordingly. We went through 4 such cycles, but we grouped the first 2 iterations into Version 1 and the second two into Version 2 because most design changes were made between iterations 2 and 3. Our prototype report format contained a month of actual data from an acute care medical ward in our hospital. The survey consisted of 10 questions exploring the following domains: layout, understandability, completeness of data, and ability to replace current reporting methods. We recorded the time participants spent looking at the report and asked one quiz question to assess whether the participant could correctly interpret data provided.
The 40 participants surveyed included the following groups: physicians (12), ward nurses (15), nurse CAUTI champions (6), quality managers (4), and infection control specialists (3). The average time spent looking at the report was 47.2 seconds (SD = 31.5s). Report Version 1: Only 45% answered the quiz question correctly. Of the 4 domains, the lowest score was in layout, receiving an average of 3.3/5 points. Users' comments suggested that a more graphical display of catheter days was needed. Report Version 2 (Figure 1): 76% answered the quiz question correctly. The lowest scoring domain was ability to replace current reporting methods, with an average score of 3.2/5 points. User comments suggested that the report will need to meet the disparate needs of different provider types.
The iterative design process improved users' abilities to correctly interpret urinary catheter data from our report. We identified different needs of different provider types in terms of catheter and CAUTI data, as a prelude to switching to automated surveillance.
