The Future of Digital Health: How UX Design is Shaping the Industry

By PARV SONDHI

As the digital health world continues to expand, more and more people are turning to apps to manage everything from diabetes and obesity to depression and anxiety. People rely on these apps for their physical and mental health, so it’s crucial that product developers ensure a safe, effective, and engaging experience for them. Healthcare experts agree.

A team of researchers and health system leaders recently introduced a new framework called “Evidence DEFINED” for evaluating digital health products. This framework offers hospitals, payers, and trade organizations a precise set of guidelines to assess the validity and safety of a digital health product. It also gives digital health companies good benchmarks to work from.

As digital health companies create new products in the space, they should keep specific points in mind — from user experience design to considerations for data privacy. While clinical outcomes will always reign supreme, the framework suggests that patient experience, provider experience, product design, and cost effectiveness can’t be discounted.

Here are a few critical considerations that product delivery teams should plan for when creating digital health apps.

Clear navigation

First things first: a user won’t use an app that’s hard to navigate. To help people stick to their health goals, developers need to create apps that are intuitive and easy-to-use. When a user logs onto an app, they want to find the content they need immediately and be guided through the experience step by step.

A lot of different people use health apps, and not all of them are tech-savvy. Health apps need to be accessible to all demographics, including people of various ages who speak different languages. It’s also important to remember that digital health apps can be used across multiple platforms, so the navigation should remain clear when switching between devices.

While navigation might seem like a no-brainer, it’s often overlooked when designing for digital health.

We Are All Designers

By KIM BELLARD

Raise your hand if you had to go through the Hunger Games labyrinth to score a COVID-19 vaccine earlier this year – figuring out which phone number(s)/website(s) to try, navigating it, answering all the questions, searching for available appointments within reasonable distances, and, usually, having to try all over again.  Or, raise your hand if you’ve had trouble figuring out how to use an Electronic Health Record (EHR) or an associated Patient Portal. 

Maybe you thought it was you.  Maybe you thought you weren’t tech-savvy enough.  But, a trio of usability experts reassure us, it’s not: it’s just bad design.  And we should speak up.

“Everyone everywhere: A distributed and embedded paradigm for usability,” by Professors Michael B. Twidale, David M. Nichols, and Christopher P. Lueg, was published in Journal of the Association for Information Science and Technology (JASIST) in March, but I didn’t see it until the University of Illinois School of Information Sciences (where Dr. Twidale is on faculty) put out a press release a few days ago. 

The authors believe that bad design has costs — to users and to society — yet: “The total costs of bad usability over the life of a product are rarely computed. It is almost like we as a society do not want to know how much money has been wasted and how much irritation and misery caused.”

Whatever the numbers are, they’re too high.

As Dr. Twidale said:

Making a computer system easier to use is a tiny fraction of the cost of making the computer system work at all. So why aren’t things fixed? Because people put up with bad interfaces and blame themselves. We want to say, ‘No, it’s not your fault! It is bad design.'”

He specifically referenced the vaccine example: “When hard to use software means a vulnerable elderly person cannot book a vaccination, that’s a social justice issue.  If you can’t get things to work, it can further exclude you from the benefits that technology is bringing to everyone else.”
