Health Literacy by Design: How to Make Complex Information Accessible

The healthcare marketing industry talks about health literacy constantly. Far fewer of us design for it.

For HCP marketers at pharma and biotech, the gap shows up in a familiar place: a brand has the science, the data, and the clinical story. The audience has the cognitive bandwidth of someone reading between patients, in an exam room, on a phone, in eleven minutes. Somewhere between those two realities, comprehension is supposed to happen. Most of the time, it doesn’t.

That isn’t a copywriting problem. It’s a design one.

Health literacy by design is the discipline of building communication so that the person on the receiving end can actually use it, to make a decision, to take a next step, to feel less alone in a moment that matters. Here is how we approach it.

Start with the decision, not the data

Most brand materials are organized around what the brand wants to say. The order of operations is usually some version of: hero claim, mechanism of action, efficacy data, safety profile, dosing. That structure makes sense in a slide deck review. It does not match how anyone reads under pressure.

Designing for health literacy starts with a different question: what decision is this piece of communication helping someone make? An HCP weighing a new therapy against a current standard of care. A patient choosing whether to start treatment. A caregiver figuring out what tomorrow looks like. Once you know the decision, the hierarchy reorganizes itself. The lead is no longer the brand’s strongest claim. It is the audience’s most immediate question.

Translate clinical data into plain language without dumbing it down

There is a difference between simplifying and condescending, and clinical audiences feel that difference instantly. HCPs do not want clinical complexity removed. They want it presented in a way that respects their time. Patients do not want to be talked down to. They want language that does not require a medical degree to parse.

Plain language in healthcare marketing is not a reading level. It is a discipline. It means short sentences when a short sentence will do. Active voice. Specific verbs. One idea per sentence. Numbers grounded in context so a percentage means something. And critically, it means cutting the words that exist to sound credentialed rather than to communicate, the qualifiers, the jargon-as-armor, the sentences that say nothing but take up space.

The test is not whether the words are simple. The test is whether the meaning is intact.

Design the treatment journey, do not just describe it

Treatment journeys are one of the highest-stakes communication challenges in pharma marketing. A patient is being asked to understand a course of action that may unfold over months, years, or a lifetime. A linear list of steps almost never captures that.

Designing for health literacy here means giving someone a mental model of the journey before you give them the details. What is this going to feel like? What changes day to day, week to week? What is the milestone that tells me I am on track? Where do I get help when something does not look right? When a treatment journey is designed instead of described, the audience can hold the whole shape of it in their head, which is the precondition for being able to act on any of it.

Use visual hierarchy to do half the work

Health literacy is not just a language problem. The eye scans before the brain reads, and what the eye finds first frames everything that follows.

Visual hierarchy in patient-facing materials is doing real work whether you design it deliberately or not. Headlines that telegraph the point. White space that lets the page breathe. Iconography that anchors abstract concepts. Color used to signal urgency, not just brand. A single chart that replaces three paragraphs of explanation. The design tells the story before a single word is read closely.

Test for comprehension, not just compliance

MLR review confirms that a piece of communication is allowable. It does not confirm that it is understandable. Those are two different bars, and the industry routinely treats the first one as if it satisfies the second.

Designing for health literacy means building comprehension testing into the process the same way you build in legal review. Not focus groups about brand feeling, but structured comprehension checks: did the reader come away with the right takeaway, the right next step, the right understanding of risk? The answer is often instructive in ways that change the work.

The standard we hold ourselves to

Every piece of healthcare communication is, somewhere down the line, going to land in front of a person who is scared, rushed, or all three. Designing for health literacy is the work of meeting that person where they are, with respect for what they are carrying.

It’s a discipline more than a checklist. It shapes the brand, the data presentation, the treatment journey, the layout. When the discipline holds, communication doesn’t just get clearer. It changes whether someone can act on what they have read.

If you are working on a brand where the science is strong but the audience keeps missing it, that is the gap we exist to close. We would welcome a conversation.
