Current usability evaluation methods for health technologies often fail to adequately consider or include marginalized user groups, leading to potential safety and effectiveness risks. This user-centred design research insight is drawn from a 2026 study published in Human Factors in Healthcare. Using Failure modes and effects analysis (fmea) through expert workshops. with 10 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Proactively integrate equity considerations into the design of usability evaluation methods, focusing on diverse participant recruitment and tailored evaluation criteria.
Equity Gaps in Health Tech Usability Testing Identified
Current usability evaluation methods for health technologies often fail to adequately consider or include marginalized user groups, leading to potential safety and effectiveness risks.
Human Factors in Healthcare · 2026
Key Findings
- 01Failure modes in heuristic evaluation were related to evaluator expertise and a lack of heuristics addressing marginalized groups' needs.
- 02Failure modes in usability testing were predominantly related to challenges in recruiting users from marginalized groups.
- 03Current methods may not uncover usability problems affecting marginalized groups.
Application
Design takeaway
Proactively integrate equity considerations into the design of usability evaluation methods, focusing on diverse participant recruitment and tailored evaluation criteria.
How to apply
When planning usability evaluations for health technologies, explicitly map out potential equity risks and develop mitigation strategies for participant recruitment and evaluation criteria.
Project actions
- 01Consider the diversity of your target user group from the outset of your design project.
- 02When planning user testing, think about how you will recruit participants who represent different backgrounds and needs.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Utilizes a recognized risk analysis technique (FMEA) for a novel application in usability.
- +Involves experienced practitioners in the field.
Limitations
Recruiting a truly representative sample for user testing can be challenging due to time, budget, and access constraints.
Reliability & validity
The reliability of the FMEA process depends on the consensus among the expert participants. Validity is supported by the use of a structured risk analysis technique applied to a relevant domain.
Think critically
How might the findings of this study apply to the usability of non-health-related technologies, and what specific adaptations would be necessary?
Design Principles
"Usability evaluations must be designed with equity at their core to ensure the safety and effectiveness of technologies for all users."
This research highlights a critical blind spot in the design and development of health technologies. By not proactively addressing the needs and participation of diverse user populations, designers risk creating products that are not only less effective but potentially unsafe for significant segments of the population.
What This Means for Your Design
When testing health technology, we need to make sure we are testing with and for everyone, not just the most common users, otherwise, the technology might not work well or could even be dangerous for some people.
How to use in your project
