A patient can receive instructions in the right language, read every word and still leave without knowing how to take medication safely.
Consider this common prescription instruction:
“Take one tablet orally twice daily with food. Avoid concurrent use of NSAIDs.”
The sentence may be medically accurate and correctly translated. But does the patient know what an NSAID is? Does “twice daily” mean exactly 12 hours apart? Does “concurrent use” mean at the same time or at any point during treatment?
This is one of healthcare’s most overlooked communication problems. Translation can tell patients what was said, but plain language helps them understand what it means and what they need to do next.
That distinction has real consequences. When instructions are technically correct but difficult to understand, patients are more likely to take medications incorrectly, miss follow-up care or overlook important warning signs.
Effective healthcare communication requires more than translating words from one language into another. It requires medical accuracy, plain language and a way to confirm that the patient truly understands.
Health Literacy Affects More Patients Than Many People Realize
Health literacy is the ability to find, understand and use health information to make decisions. It affects how patients take medications, prepare for procedures, manage chronic conditions and recognize when they need additional care.
Approximately 80 million adults in the United States have limited health literacy. Nearly half of people with low health literacy have completed college or hold a graduate degree.
This means health literacy is not simply a reflection of education. It often reflects the gap between how medical information is presented and how people process it, especially when they are sick, stressed or facing an unfamiliar diagnosis.
The average reading level for adults in the United States is around seventh grade. Patient-facing healthcare materials are often recommended to be written at a fourth- to fifth-grade reading level.
Despite this, prescriptions, discharge instructions, consent forms and patient education materials frequently contain clinical terminology and complicated sentence structures.
The consequences can be serious. Patients with limited health literacy experience higher rates of medication errors, missed follow-ups, avoidable hospital visits and difficulty managing chronic conditions.
Translation Does Not Always Solve the Underlying Problem
Translation addresses the language of a message. It does not automatically make the message clearer.
A phrase such as “concurrent use is contraindicated” can be translated accurately into another language and remain difficult to understand. A clearer version would be: “Do not take these medicines together.”
The problem often begins before translation takes place. When the original English message contains jargon, vague wording or long sentences, a faithful translation may preserve those same problems.
Word-for-word translation may also fail to communicate the practical meaning a patient needs. Patients usually want to know what is happening, what they need to do, when they need to do it and when they should ask for help.
A technically accurate translation can therefore still be ineffective. The goal should not be to reproduce every word, but to preserve the meaning in a form the patient can understand and act on.
Plain Language Should Begin Before Translation
Clear multilingual communication often starts by simplifying the original message. Healthcare teams should first make the information direct, actionable and easy to follow, then preserve that clarity across languages.
Federal guidance from the Centers for Medicare & Medicaid Services, the National Institutes of Health and the Agency for Healthcare Research and Quality consistently emphasizes several plain-language principles.
Start With What the Patient Needs to Know
Before writing or explaining something, providers should consider who will receive the information and what that person needs to do with it.
A patient may not need every clinical detail at once. The most important information is often the diagnosis, the next step, the medication plan and the warning signs that should prompt a call or return visit.
The most important action should appear first. Background information and supporting details can follow.
For example, instead of beginning with a long explanation of how a medication works, a provider might begin with: “Take one pill every morning with breakfast.”
Use Familiar Words
Everyday language is usually easier to understand than clinical or administrative terminology.
“Prior to” can become “before.”
“Utilize” can become “use.”
“Administer the medication orally” can become “swallow the pill.”
“Report to the emergency department if symptoms worsen” can become “Go to the emergency room if you have trouble breathing or your pain gets worse.”
The clearer version is not less accurate. It simply makes the intended action easier to understand.
Keep Sentences Short and Focused
Long sentences often contain several instructions at once. This can make it difficult for patients to remember what matters most.
Each sentence should focus on one main action or idea whenever possible. Short paragraphs and clear headings also make written information easier to scan.
Instead of writing:
“Continue taking the medication as prescribed and contact your primary care provider if symptoms persist or worsen before your next scheduled follow-up appointment.”
A clearer version might be:
“Keep taking the medicine as directed. Call your doctor if you do not feel better or if your symptoms get worse.”
Use Active Voice
Active voice makes it clear who should take action.
“Take this pill with food” is more direct than “This medication should be taken with food.”
“Call your doctor tomorrow” is clearer than “Your physician should be contacted the following day.”
Active voice also makes instructions easier to scan, which matters when patients are reviewing information quickly after a visit.
Organize Information by Importance
Patients should not have to search through several paragraphs to find the most important instruction.
Critical actions should appear first. Supporting explanations, exceptions and background details can follow.
A discharge summary, for example, might begin with:
“Return to the emergency room if you have chest pain, trouble breathing or fainting.”
Additional information about medications, follow-up appointments and lifestyle changes can come afterward.
Confirm Understanding
A message can meet every readability standard and still confuse an individual patient.
Teach-back is one of the most practical ways to confirm understanding. A provider can ask the patient to explain, in their own words, how they will take a medication or what they will do after leaving the clinic.
This is not a test of the patient. It is a way to determine whether the explanation was clear enough.
Instead of asking, “Do you understand?” a provider might say:
“Just so I know I explained it clearly, can you tell me how you will take this medicine when you get home?”
The patient’s answer may reveal misunderstandings that would otherwise go unnoticed.
Clear Communication Must Continue Throughout the Care Journey
Patients rarely receive health information only once. They may hear instructions during a visit, review an after-visit summary, receive a portal message and later read a printed education sheet.
Those messages are not always consistent. A provider may explain something clearly during the conversation, while the written summary contains technical language copied from the chart.
This can create confusion, especially when information is also being interpreted or translated. The patient may hear one explanation and receive a written version that appears more complicated or slightly different.
Healthcare organizations should aim to keep the same plain-language message consistent across spoken conversations, interpretation, documentation, discharge instructions and patient education materials.
For example, if a provider tells a patient, “Do not take ibuprofen while you are using this medicine,” the after-visit summary should not switch back to “Avoid concurrent NSAID use.”
Consistency helps reinforce understanding. It also reduces the risk that a patient receives conflicting instructions from different parts of the care team.
How AI Can Support Better Health Communication
Most clinicians already know that patient communication should be clear. The challenge is applying that standard consistently during busy clinical workflows.
Providers have limited time, and patient-facing information often comes from multiple systems and teams. Verbal instructions, clinical notes, after-visit summaries and translated materials may all be created separately.
AI can help identify complex language and suggest clearer alternatives. It can also help turn clinical information into practical categories such as what the diagnosis means, what the patient should do next, when the patient should worry and when the patient should return.
Its most useful role is not simply translating information faster. It is helping healthcare teams preserve the same clear meaning across different formats and languages.
AI can also support teach-back by helping providers phrase questions clearly and identify areas that may need additional explanation. It should not replace the provider’s responsibility to confirm understanding.
Not All AI Tools Are Designed for Healthcare
General-purpose translation and writing tools may be useful for everyday communication, but healthcare requires a higher level of accuracy and context.
Clinical conversations include medication names, dosing instructions, symptoms, consent language and warning signs. Small changes in meaning can have serious consequences.
A general translation tool may convert the words correctly but fail to recognize that the original message is too complicated. It may also lack the clinical context needed to preserve dosing, terminology or the relationship between different instructions.
Healthcare-specific tools can be designed to address both accuracy and clarity. They can support interpretation during the visit while also helping align clinical documentation, after-visit summaries and patient-facing materials.
How Opalite Supports Clearer Multilingual Communication
Opalite Health is one example of a healthcare-specific approach. The platform combines real-time medical interpretation, multilingual clinical documentation and patient-facing translation within the same clinical workflow.
Unlike general-purpose translation tools, Opalite is designed for medical conversations. It is built to recognize clinical terminology, medication instructions and the context of a patient encounter.
Opalite can help providers communicate with patients across more than 150 languages during the visit. It can also carry information from the conversation into clinical notes and translated follow-up materials.
This continuity matters because patients often receive different versions of the same message throughout their care. A clear verbal explanation can lose its meaning when it is later converted into a technical after-visit summary.
By supporting interpretation, documentation and translation in one platform, Opalite helps healthcare organizations keep those messages more consistent.
The goal is not simply to translate a complicated sentence into another language. It is to preserve the medical meaning while helping the provider communicate in a way the patient can understand and use.
Better Communication Requires Accuracy and Understanding
Language access is essential to equitable healthcare, but patients need more than information in the correct language. They need information they can understand and act on.
That starts with plain language, clear organization and confirmation of understanding. Translation should preserve those qualities rather than simply reproduce the original words.
Healthcare teams should ask a simple question whenever they communicate with patients:
Will the patient know what to do next?
If the answer is unclear, the message is not finished.
The goal of healthcare communication is not simply to deliver information. It is to help patients understand what is happening, what they need to do and when they need to seek help.
