Graphical icons have been introduced as a design solution, i.e., task-driven icons, to improve certificate nurse assistants (CNAs) charting efficiency in long-term care settings. It aims to motivate CNAs to complete POC documentation at work, thus reduce the after-hour charting workload. Currently, few studies have examined the effectiveness of task-driven icons in POC systems and their performance on affecting users’ charting behaviors. This study intends to investigate existing types of task-driven icons in POC systems, and whether those icons have effectively influenced CNAs’ charting behaviors. By analyzing ways of interpreting icons and associating charting tasks, we aim to establish design considerations of the task-driven icons used for POC documentation on future implementations.
