Designing digital health tools with direct input from target users and experts leads to more intuitive and effective applications for managing chronic conditions. This user-centred design research insight is drawn from a 2025 study published in BMC Health Services Research. Using Iterative design and usability testing with 35 participants (15 experts, 20 IBD patients), researchers explored how this design variable affects real-world outcomes. The key design takeaway: Incorporate direct user feedback and iterative testing throughout the design process to ensure digital health tools are intuitive, relevant, and meet the specific needs of the target patient population.

Key Findings
- 01Core features designed around patient needs and expert feedback included personalized health summaries, symptom tracking, and medication adherence monitoring.
- 02Usability testing and expert evaluation led to refinements in the user interface, resulting in a simplified and more intuitive design.
- 03The iterative process of feedback and refinement improved the overall usability of the application.
Application
Design takeaway
Incorporate direct user feedback and iterative testing throughout the design process to ensure digital health tools are intuitive, relevant, and meet the specific needs of the target patient population.
How to apply
When developing any digital tool intended for user interaction, especially in sensitive areas like health, begin by thoroughly researching and understanding the end-user's needs, workflows, and pain points. Integrate these insights into the design and validate through repeated user testing.
Project actions
- 01Clearly define your target user group and their specific needs early in the project.
- 02Incorporate user feedback loops at multiple stages of your design process, not just at the end.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Inclusion of both patient and expert perspectives.
- +Iterative design process with multiple testing phases.
Limitations
The user group in this study was specific to IBD patients. Your own design project might have a different user group, so consider how their needs might differ.
Reliability & validity
The study employed heuristic evaluation (expert review) and usability testing with actual users, which contributes to both reliability (consistency of expert judgment) and validity (measuring what it intends to measure – usability). The iterative nature also strengthens validity by ensuring the final product is well-tested.
Think critically
How might the specific needs of IBD patients differ from those of patients with other chronic conditions, and how would those differences necessitate changes in app design?
Design Principles
"User needs should drive the design and feature set of digital health applications, with continuous validation through user testing."
In the development of digital health solutions, a user-centred approach is paramount. By involving patients and healthcare professionals throughout the design and testing phases, developers can ensure the final product addresses real-world needs and is easy to navigate, thereby increasing adoption and efficacy.
What This Means for Your Design
If you want to make an app that people will actually use and find helpful, especially for health, you need to ask them what they need and test your ideas with them as you go.
How to use in your project
- 1.Reference this study when justifying the importance of user research and iterative design in your own design project.
- 2.Use the findings to support your methodology if you are employing user-centred design principles.
