Visualizing medication information using hierarchical task analysis and infographics in a mobile device
ABSTRACT
Background:
Despite the detailed patient package inserts (PPIs) with prescription drugs to communicate crucial information about safety, there is a critical gap between patients’ understanding and the knowledge presented. As a result, patients may suffer from adverse events. We propose that utilizing human-factors design methodologies such as hierarchical task analysis (HTA) and interactive visualization may bridge this gap. Our hypothesis is an innovative mobile application that employs human-factors design with an interactive visualization can deliver PPI information aligned with patients’ information processing heuristics. Such an application may help the patient with an improved overall knowledge of the medication.
Objective:
The objective of this study was to explore the feasibility of designing an interactive visualization-based mobile application using an HTA approach through a mobile prototype.
Methods:
Two pharmacists constructed the HTA for the drug risperidone. Later, the specific requirements of the design were translated using infographics. We transferred the wireframes of the prototype into an interactive user interface. Finally, a usability evaluation of the mobile health application was conducted.
Results:
A mobile application prototype using HTA and infographics was successfully created. We reiterated the design based on the specific recommendations from the usability evaluations.
Conclusions:
Using the HTA methodology, we successfully created a mobile prototype for the drug risperidone. The hierarchical goals and subgoals were translated into a mobile prototype.
