Medical reports and after-visit summaries are often written for other clinicians, not for the patient reading them. Terms like "idiopathic," "unremarkable," or "titrate" carry precise clinical meaning that isn't obvious from context, and looking them up one at a time in a general search engine is slow and can surface unreliable results. A chatbot can turn a dense paragraph into a plain-language explanation in seconds — but only if you prompt it correctly, and only if you treat the output as a starting point rather than medical advice.
Getting a genuinely simple explanation
1. Paste the exact text, not a summary of it. Copy the sentence or paragraph containing the term directly from your report. Rephrasing it yourself first risks introducing an error before the model even sees it.
2. Specify the reading level you want. Left to its own defaults, a chatbot's "plain language" answer tends to land around a college reading level — the opposite of simple. Ask explicitly: "Explain this at about a 6th-grade reading level, the way you'd explain it to a family member with no medical background."
3. Ask it to flag anything it's uncertain about. A follow-up like "Which parts of this are you most and least confident about?" surfaces hedging the model might otherwise smooth over.
4. Verify against a plain-language medical reference. MedlinePlus (medlineplus.gov), run by the U.S. National Library of Medicine, covers most common conditions, tests, and terms in the same plain style you just asked the chatbot for — use it to sanity-check the explanation, not just to double up on convenience.
5. Bring real questions to your clinician, not conclusions. A chatbot explanation is useful for understanding vocabulary before an appointment; it's not a diagnosis or a treatment recommendation, and it doesn't have access to your full chart.
# A prompt template that requests an explicit reading level
# instead of relying on the model's default "simple" framing
Here is a sentence from my after-visit summary:
"Findings are consistent with mild bilateral idiopathic
peripheral neuropathy; recommend outpatient EMG for
further characterization."
Please:
1. Explain this at roughly a 6th-grade reading level,
as if explaining it to a family member with no
medical background.
2. Define each unfamiliar term separately (idiopathic,
bilateral, peripheral neuropathy, EMG).
3. Tell me which parts you are least confident about.
4. Remind me this is not medical advice and that I
should confirm with my doctor.
| Approach | Typical Reading Level | Best Use |
|---|---|---|
| Chatbot's unprompted default explanation | ~13th-14th grade (college level), per 2025 readability study | Not recommended as-is for patient use |
| Chatbot explicitly prompted for 6th-grade level | Meaningfully lower, though not independently benchmarked here | Quick vocabulary orientation before an appointment |
| MedlinePlus consumer health pages | Written in plain language by NLM staff for a general audience | Verifying or cross-checking a chatbot's explanation |
The honest limitation here is that no chatbot can guarantee its explanation is complete or free of errors — large language models can misstate clinical nuance, especially around dosing, prognosis, or rare conditions. Treat a chatbot explanation as a translation of vocabulary, not a second opinion, and route anything that affects a real decision back to a licensed clinician or a reference like MedlinePlus that's reviewed by medical librarians.
Practical Challenge
Take one unfamiliar term from a real lab result or prescription label and ask a chatbot to explain it twice: once with no instructions, and once explicitly requesting a 6th-grade reading level. Compare the two answers side by side.
