Inclusive Design for Digital Health Interventions for Older Adults: A Comparative Analysis of Literature, Expert, and User Perspectives
This study triangulates literature, expert, and older adult perspectives to demonstrate that inclusive design for digital health interventions targeting older adults must extend beyond usability and accessibility to encompass emotional, ethical, and systemic dimensions, with a strong consensus on the foundational importance of personalization and ongoing user support.

Imagine you are building a house. You have three different groups of people giving you advice on how to make it comfortable for an elderly resident:
- The Architects (The Literature): They have read every blueprint ever written. They know the rules of physics and the standard codes for door widths and stair heights.
- The Contractors (The Experts): These are the people who actually build the houses. They know what materials are available, how to get permits, and how to make sure the plumbing connects to the city grid.
- The Residents (The Older Adults): These are the people who will actually live there. They know what it feels like to trip on a loose rug, how hard it is to read small print in the morning, and what makes them feel safe and welcome.
This paper is a meeting where these three groups sat down to compare their notes on designing Digital Health Interventions (DHIs). These are apps, websites, and devices meant to help older adults manage their health. The goal was to figure out: What does a truly "inclusive" digital health tool look like for an older person?
Here is what they found, broken down simply:
1. The Common Ground (The "Must-Haves")
When the Architects, Contractors, and Residents compared their lists, they all agreed on four big things. Think of these as the foundation of the house:
- Big, Clear Signs (Usability & Accessibility): Everyone agreed that the "house" needs big doors and clear signs. In digital terms, this means large fonts, high-contrast colors, and big buttons. No tiny text or confusing menus.
- A Simple Map (Navigation): The path through the house shouldn't be a maze. Users need to know exactly where they are and how to get back to the front door (the main screen) without getting lost.
- Customizable Rooms (Personalization): Not everyone needs the same thing. Some people want the lights dimmed; others want them bright. Digital tools should let users adjust the size of text, the speed of lessons, or the type of reminders they get.
- A Helpful Concierge (Support): You can't just drop someone off at the door and walk away. There needs to be a guide. This means tutorials, step-by-step instructions, and real humans available to help if things go wrong.
2. What Each Group Brought to the Table
While they agreed on the foundation, each group had a unique perspective on the "furniture" and "systems" of the house.
The Architects (Literature Review) focused on the Rules:
They emphasized fairness and access. They pointed out that a digital health tool is useless if it costs too much or if the user's insurance won't cover it. They also stressed that the tool should work on any device (like a tablet, phone, or computer) and that the content should be tailored to the user's specific culture and language.
The Contractors (Experts) focused on the Systems:
The experts looked at the "plumbing" and "wiring" behind the walls. They said:
- Integration: The app needs to talk to the doctor's office. If a doctor recommends an app, the doctor needs to know how it works.
- Safety & Trust: They worried about data privacy. They said the system must be secure, and users need to know exactly where their data is stored.
- Co-Design: You can't build the house without asking the resident what they want. Experts insisted that older adults must be involved in the design process from the very beginning, not just at the end.
- Hardware: Even the physical devices (like hearing aids or smartwatches) need to look good so people don't feel embarrassed wearing them.
The Residents (Older Adults) focused on the Feelings:
This was the most surprising part. While the experts talked about regulations and the architects talked about standards, the older adults talked about emotions and safety.
- Reassurance: They wanted to know, "Did the app save my data?" or "Did I do this right?" They needed constant, gentle confirmation that they weren't making mistakes.
- Human Connection: They didn't want to talk to a robot chatbot. They wanted to be able to call a real person if they were confused.
- Analog Options: Some people just don't want to use technology. The residents said there must be a "paper" or "phone" alternative for those who can't or won't use the app.
- Trust: They only trusted the app if a doctor or a trusted organization recommended it. If it felt like a scam or a surveillance tool, they wouldn't use it.
3. The Big Takeaway
The paper concludes that building a digital health tool for older adults isn't just about making the buttons big or the text clear.
It's about building a safe, trustworthy, and human-centered environment.
- The "House" (The App) must be easy to navigate.
- The "Plumbing" (The System) must be secure and connected to real healthcare.
- The "Atmosphere" (The Experience) must make the resident feel calm, respected, and supported, not anxious or confused.
The authors say that if you want to build a digital health tool that older adults will actually use, you need to listen to all three voices: the rules, the builders, and the people living there. If you miss any of them, the house might be built, but no one will want to live in it.
