PlainLanguage Guide
Why Plain Language Works In Healthcare
Clear, everyday language improves understanding, supports safer decisions, reduces costs, and helps organizations operate more effectively.
What Is the communication gap in healthcare?
Health information is meant to support informed decisions. But it is often written in technical language or organized in ways that make it difficult to use. Limited comprehension often reflects how information is written and structured.
Plain language addresses this gap by presenting information in ways people can quickly understand and act upon.
The result: People have a better chance of understanding important health information.

Plain Language Challenges In Healthcare
How does plain language help people?
Plain language is communication that people can find, understand, and use the first time they read or hear it.
In healthcare, plain language means:
- Using familiar, everyday words
- Organizing information so key points appear first
- Writing clear instructions that tell people what to do next
- Avoiding unnecessary jargon or technical phrasing
Plain language does not mean oversimplifying information. It means presenting important information in ways people can easily understand and act on.
Research shows that clearer materials can:
- Increase understanding by about 30%
- Reduce medication dosing errors by up to 46%
How does plain language benefit health organizations?
Plain language helps readers and it produces measurable benefits for health organizations.
Organizations that implement plain language practices can:
- Reduce avoidable/unnecessary service use
- Improve adherence to care instructions
- Strengthen patient safety
- Improve patient experience and satisfaction
- Increase accessibility for diverse populations
- Build trust in information and services
Clear communication supports better outcomes for both individuals and the systems that serve them.
What are plain language best practices?
Organizations can improve communication by following key plain language practices:
- Use common, familiar words instead of technical terms
- Write in short sentences and paragraphs
- Put the most important information first
- Use headings and lists to organize information and improve navigation
- Provide clear instructions about what to do next
Even small changes in wording and structure can significantly improve understanding.
What does plain language look like in healthcare?
These principles become clearer when you see how they are applied to real communications. For example:
Before (technical language)
Patients should administer the medication bi-daily and discontinue use if adverse gastrointestinal symptoms occur.
After (plain language)
Take this medicine twice a day. Stop taking it and call your doctor if you have stomach pain or vomiting.
Clear wording helps readers understand instructions quickly and reduces the chance of medication errors.
