OPTIMISE-ing consent in clinical trials: recommendations for designing accessible consent processes to address communication and decision-making needs as a barrier to participation
The OPTIMISE study developed a comprehensive framework of three guiding principles and seven practical domains to help researchers design accessible clinical trial consent processes that overcome communication and decision-making barriers for people with impaired capacity.

Imagine clinical trials as a massive, high-stakes treasure hunt. The goal is to find the best cures for everyone. But for a long time, the map to the treasure has been written in tiny, confusing, legalistic font, and the path has been blocked by invisible walls. This paper argues that people with communication or decision-making needs—like those with dementia, learning disabilities, or who have had a stroke—are often locked out of the hunt not because they can't find the treasure, but because they can't read the map or get past the gatekeeper.
The authors, a team of researchers and people with lived experience, didn't just point out the problem; they built a new, accessible map called OPTIMISE. Their main finding is that to let everyone in, we need to redesign the "consent process" (the moment someone agrees to join the study) so it is accessible by design. They suggest that if researchers follow three guiding principles and tweak seven specific parts of the process, they can break down these barriers.
The Three Golden Rules (Guiding Principles)
Think of these as the rules of the game that must be followed to keep the treasure hunt fair:
- Collaboration: You can't build the map alone. Researchers need to team up with speech therapists, family members, and the people who will actually be joining the hunt. It's a group effort, not a solo mission.
- Ethics: This isn't just about following rules; it's about respect. It means building trust, treating people like partners, and making sure the process doesn't feel like a trap.
- Reflection: Keep checking your work. Ask yourself: "Is this actually working for everyone? Is the burden too heavy? Are we listening?" It's like a captain constantly checking the compass to make sure they aren't drifting off course.
The Seven Keys to Unlock the Gate (The Domains)
The paper suggests that researchers can make the process accessible by adjusting seven specific areas. Think of these as the different tools in a toolbox:
- Content: The story you tell must be clear. Don't just dump a wall of text. Explain the "what," the "why," and the "what happens next" in a way that makes sense.
- Language: Ditch the jargon. Use short sentences and simple words. If the person speaks a different language, you need a translator, not just a dictionary.
- Format: One size does not fit all. Some people need a video, some need a picture book, some need an audio recording, and some need a simple "Easy Read" sheet. The paper suggests offering multiple ways to get the info, like having a menu of options.
- Design: The look matters. Use big fonts, clear pictures, and plenty of white space. It's like designing a room that isn't cluttered so you can actually see where you're going.
- Support: Sometimes you need a helper. This could be a communication card, a memory aid, or a trusted friend to help explain things. Crucially, the helper should help the person speak for themselves, not speak for them.
- Timing: Timing is everything. You can't ask someone to make a big decision when they are in pain, confused, or in an emergency. You might need to give them the info in stages, or check back with them later when they feel better.
- Environment: Where you talk matters. Is the room too loud? Is the lighting too bright? Is it a place where the person feels safe? The setting needs to be calm and comfortable, not a chaotic hospital corridor.
What This Paper is NOT
It is important to know what this paper does not do. It does not say that the current system is broken beyond repair, nor does it claim that simply handing out a "Easy Read" leaflet solves every problem. The authors explicitly argue against the idea that consent is just a one-time signature on a piece of paper. They also reject the notion that people with communication needs are automatically incapable of making decisions; instead, they argue the system fails to support them.
How Sure Are They?
The authors are confident that these ideas work in theory and should work in practice, but they are careful not to claim they have already proved it with hard numbers. They built these recommendations by looking at 26 existing studies and talking to 21 experts and people with lived experience in a workshop. They say these recommendations suggest a better way forward. They admit that while the ideas are strong, they haven't yet been formally tested in a massive, controlled experiment to see if they actually change the outcome in real-world trials. They describe their work as a "comprehensive framework" and a "toolkit" to help researchers start doing better, rather than a finished, perfect solution.
The Takeaway
The paper suggests that even small, achievable changes—like using simpler words, offering a video option, or picking a quieter room—can make a huge difference. It's not about reinventing the wheel; it's about greasing the axles so the wheel can actually roll. The goal is to ensure that the treasure hunt is open to everyone, not just those who can read the fine print. The full map and the toolkit are available online for anyone who wants to start building a more inclusive path.
