Using Qualitative Methods to Create a Home Health Web Application User Interface for Patients with Low Computer...

Area of Science:

• Health Informatics
• Human-Computer Interaction
• Health Services Research

Background:

• Public reporting of healthcare quality data is underutilized by consumers.
• Existing reports often fail to incorporate effective consumer-facing design recommendations.
• There's a need for improved web applications to help consumers select healthcare providers.

Purpose of the Study:

• To develop and iteratively test a consumer-facing home health web application prototype.
• To identify design recommendations for web applications targeting older adults with varying health and computer literacy.
• To improve the usability and accessibility of online health information for vulnerable populations.

Main Methods:

• A multi-phased approach including evidence-based design review, paper prototyping, and wireframing.
• Qualitative research involving focus groups with consumers and interviews with hospital case managers.
• Iterative refinement of the user interface based on user feedback and usability testing.

Main Results:

• User groups responded favorably to the prototype, indicating perceived usefulness.
• Case managers provided crucial input on legal compliance and workflow integration.
• Usability testing revealed that consumers, particularly older adults, required more prompts and clearer navigation, leading to design modifications.

Conclusions:

• Web application design for older adults must account for lower computer proficiency and adapt standard web design principles.
• Overestimation of computer familiarity can hinder usability for the target demographic.
• Future development of consumer-facing health technology should prioritize end-user testing and tailored design for vulnerable populations.
