How we verify

The standard

Every medical statement on MedGrasp is checked against current, credible sources. Those are clinical guidelines from named bodies (for example the World Health Organization, national guideline bodies and specialty societies), peer-reviewed articles, and standard reference books and drug references. Where guidance differs between regions, the topic says so. Nothing is invented: a fact that cannot be confirmed is left out or its uncertainty is stated.

The steps

1. Write from sources. The topic is written in new words from sources that were opened and read for that purpose. Facts are free to use; the wording is ours.
2. Check every reference. Each reference is a real page that was opened and confirmed to say what the topic cites it for. The topic lists the date each one was accessed.
3. Check the claims, separately. A second pass, not made by the writer, goes through the topic claim by claim: every number, dose, criterion and first-line choice is compared with the source, and newer versions of guidelines are looked for. Any error sends the topic back to be fixed and checked again. A single error that could harm a patient stops publication.
4. Check the originality. An automated check compares the text with the sources it was written from and fails any copied run of words.
5. Look at it. The finished page is opened and looked at on a phone-sized and a desktop-sized screen, so that figures, tables and flowcharts are readable.

Who does the checking

Writing and checking are done with AI tools working under written rules, and the checking pass is a separate run that did not write the topic. This is why the usual label is “Checked against sources” and not “Reviewed by a clinician”: the second label is used only when a named clinician has read the topic.

What the labels mean

Checked against sources

The topic went through the steps above. It has not been read by a clinician.

Reviewed by a clinician

A named doctor has read the topic. The label gives the name and the date, and appears only when it has happened.

Last verified

The date the topic was last checked in full against its sources. A topic is checked again when guidance changes.

Sample page

A page written to test how topics look and work. It is not part of the library and is marked so that search engines skip it.

What we cannot promise

Medicine changes, and a page can be wrong or out of date. A topic is not medical advice and does not replace clinical judgement, senior supervision, local guidelines or your local drug formulary. Read the medical disclaimer. A button to report an error on each topic is not built yet; Copyright and takedown says how reports are handled, and the editorial policy sets out the rules these steps follow.
