The U.S. FDA and international regulatory bodies require usability testing of medical devices, products, software, and systems as part of their overall validation. Manufacturers must demonstrate that all potential use-related hazards have been identified, prioritized, and mitigated. The method for demonstrating this is human factors/usability engineering (HF/UE) validation testing. However, the way we conduct these studies is in many ways different from the way we conduct studies of non-medical products and systems.
This topic is relevant to the Boston UX community given the convergence of consumer and medical devices, as well as the rise of wearable technologies and the apps that interact with them. This presentation will cover the key aspects of HF/UE validation (a.k.a. ‘summative’) testing and what the FDA expects in the final HF/UE summary report.
Importantly, this session will consist of half presentation and half Q&A, with the audience driving the discussion toward current issues, questions, and challenges that are relevant to them.

User Interface Design for Medical Devices - The Relationship Between Usability and Safety
Rich Newman's presentation from the UXPA Boston 2016 conference
Risk management in the development of medical devices. This presentation was for a webinar where we discussed the basics of risk management, a general risk management lifecycle, the requirements of certain relevant standards (ISO 14971, IEC 62304, US FDA Title 21 CFR Part 11), and the practical method called HFMEA. The live demonstration shows you how risks can be managed and compliance achieved using the advanced risk management features of codeBeamer ALM, and also demonstrates the use of our (general) FMEA template.

Risk Management for Medical Devices. An overview of ISO 14971 & how to apply a "Risk-based Approach" to your QMS processes to address the upcoming changes to ISO 13485.
IEC 62304 is the international standard that defines software development lifecycle requirements for medical device software. The standard was developed from the perspective that product testing alone is insufficient to ensure patient safety when software is involved. The standard requires all aspects of the software development life cycle to be scrutinized.

Presentation by Michael imhoff about the upcoming Medical Device Regulation (MDR) in the EU. Includeds compliance with the General Safety and Performance Requirements. Demonstration of conformity with the general safety
and performance requirements in clinical
evaluation. Clinical evaluation with evidence for safety
and performance of the medical device. Assessment of side effects and the acceptability of the risk-benefit-ratio, based on clinical data. MDR is not a health technology assessment for payers. Results of the clinical evaluation should be documented
in a clinical evaluation report (CER).
What do hospital beds, blood pressure cuffs, dosimeters, and pacemakers all have in common? They are all medical devices with software that regulates their functionality in a way that contributes to Basic Safety or Essential Performance. With the FDA reporting that the rate of medical device recalls between 2002 and 2012 increased by 100% – where software design failures are the most common reason for the recalls – it’s no wonder IEC 62304 has been implemented. Its implementation, however, has medical device manufacturers asking questions about if, when and under what circumstances the standard is required.
This article explains what IEC 62304 is, when medical devices must comply with it and how IEC 62304 compliance is assessed.

Make It Fast: Delivering UX Research to Agile TeamsUXPA Boston
One of the biggest challenges facing UX designers working with agile teams is providing user research in a quick, effective way. Design sprints take less time than in the past and development makes it difficult to slip user feedback into the mix. Traditional research takes time to design, set up, recruit for, run and analyze. Since that could span several sprints, “traditional” research simply doesn’t work in today’s rapid pace development, and the user experience suffers. Many organizations are tackling this challenge.
We’ve brought together 4 panelists who are using methods to address the issue of rapid UX research. Panelists come from both in-house teams and agencies. We’ll share our approaches and offer practical advice about how to do it, why it works and what could be improved. We’ll cover both unmoderated tests and more traditional moderated tests. You’ll learn some new approaches and get a chance to ask questions or share your own experiences.

Book Formatting: Quality Control Checks for DesignersConfidence Ago
This presentation was made to help designers who work in publishing houses or format books for printing ensure quality.
Quality control is vital to every industry. This is why every department in a company need create a method they use in ensuring quality. This, perhaps, will not only improve the quality of products and bring errors to the barest minimum, but take it to a near perfect finish.
It is beyond a moot point that a good book will somewhat be judged by its cover, but the content of the book remains king. No matter how beautiful the cover, if the quality of writing or presentation is off, that will be a reason for readers not to come back to the book or recommend it.
So, this presentation points designers to some important things that may be missed by an editor that they could eventually discover and call the attention of the editor.

Transforming Brand Perception and Boosting Profitabilityaaryangarg12
In today's digital era, the dynamics of brand perception, consumer behavior, and profitability have been profoundly reshaped by the synergy of branding, social media, and website design. This research paper investigates the transformative power of these elements in influencing how individuals perceive brands and products and how this transformation can be harnessed to drive sales and profitability for businesses.
Through an exploration of brand psychology and consumer behavior, this study sheds light on the intricate ways in which effective branding strategies, strategic social media engagement, and user-centric website design contribute to altering consumers' perceptions. We delve into the principles that underlie successful brand transformations, examining how visual identity, messaging, and storytelling can captivate and resonate with target audiences.
Methodologically, this research employs a comprehensive approach, combining qualitative and quantitative analyses. Real-world case studies illustrate the impact of branding, social media campaigns, and website redesigns on consumer perception, sales figures, and profitability. We assess the various metrics, including brand awareness, customer engagement, conversion rates, and revenue growth, to measure the effectiveness of these strategies.
The results underscore the pivotal role of cohesive branding, social media influence, and website usability in shaping positive brand perceptions, influencing consumer decisions, and ultimately bolstering sales and profitability. This paper provides actionable insights and strategic recommendations for businesses seeking to leverage branding, social media, and website design as potent tools to enhance their market position and financial success.

• Software that simply retrieves and/or organizes data.
• Mobile apps that are electronic copies of medical textbooks,
teaching aids or reference materials, etc.
• Mobile apps that are solely used to log, record, track,
evaluate, or make decisions related to developing or
maintaining general health and wellness.
Software and Apps as Medical Devices
What FDA does NOT regulate
FDA:
“…we intend to apply this oversight authority only to
those mobile apps whose functionality could pose
a risk to a patient’s safety if the mobile app were to
not function as intended.”

Important Test Inputs
• Intended user profiles.
• Intended use environments.
• Detailed task analysis.
• A user interface design.
• Use-related hazards and risks analysis (at
least preliminary).
18. 18
Formative Usability Testing
• Done early and often during development.
• To refine the design.
• Uncovers additional user requirements.
• Identifies additional use hazards.
19. 19
HF Validation Testing
• Also called “summative testing.”
• Required for FDA and CE approval.
• Based on use-related risk analysis.
• Must be conducted in a specific way.
20. 20
Determining User Profiles
• How you define user groups is key!
• “When their characteristics could affect
their interactions with the device, or when
their tasks are different.”
– Different age groups
– Different roles
– Trained vs. untrained users
21. 21
Sample Sizes for Validation
3 Loring & Wan (2017): Recruiting Patients with Rare Diseases and Their Caregivers
• Minimum of 15 participants per user profile.
• Sometimes means huge sample sizes – 60, 90, 120.
• Especially challenging for hard-to-find users.3
22. 22
Select Tasks Based on Risks
• Ensure the tasks tested include critical tasks (at a minimum).
• Define success and failure at the task level.
• Tasks that require the user to respond to alerts/alarms are considered
critical tasks and should be tested.
• Warnings and cautions in the product labeling imply critical tasks and
should be assessed through ‘knowledge questions.’
23. 23
Actual or Simulated Environment
• Mimic real world conditions:
– Lighting, acoustics, vibration
– Room layout and other equipment
– Interruptions and distractions
– Mobility and portability
• You may need to rent a medical
simulation facility.
• Multiple use environments?
24. 24
Simulating Emergency Use Conditions
• Testing conditions should mimic
emergency situation.
• Simulation of stress-induced
environments can include:
– Continuous telephone ringing
– A beeping timer that increases in frequency
and loudness
– Multiple people in a confined space
25. 25
Representative Training
• Training in the study should be the same as
training in actual use.
• If training will not be provided consistently for
every user, it may be OK to only test untrained
users.
• ‘Decay of training’ period is often required.
26. 26
Moderating a Validation Test
• It’s different than what you may be used to!
• Simulate realistic interactions:
– Don’t tell participants to read the Instructions for Use.
– No thinking aloud (unless it’s spontaneous).
– No interruptions while participants are performing the
tasks (unless they could get hurt).
– Don’t debrief until all tasks are done.
27. 27
Analyzing the Data
• Observational data (pass/fail, close calls,
operational difficulties, and
unanticipated/unknown problems).
• Interview data or subjective assessment
from study participants.
• Answers to knowledge questions.
• Perform a root cause analysis.4
4 Wiklund, et al (2015): Medical Device Use Error: Root Cause Analysis
28. 28
The HF/UE Validation Report
• Present the data in a summary table for FDA review:
• Show data by distinct user profiles.
• Provide a detailed discussion of subjective data and root cause analysis.

C=Critical
E=Essential

29. 29
Do You Need to Re-test?
• Evaluate what aspects of the UI may have caused or
contributed to the issues seen in the study.
• Determine options to further optimize the user interface.
• Implement additional UI improvements.
• Update the use-related risk analysis….then
• Decide whether to perform additional HF studies to
demonstrate that the mitigations addressed the errors and
no new risks were introduced.
30. 30
Final Conclusion
“The <Product> has been found to be reasonably safe and
effective for the intended users, uses and use environments.
And…
Any residual risk that remains after the validation testing
would not be further reduced by modifications of design of
the user interface (including any accessories and the IFU), is
not needed, and is outweighed by the benefits that may be
derived from the device’s use.”
