MEDICAL WRITING: WHAT IT IS, WHO NEEDS IT.

By María García-Puente · Research · July 2026

Medical writing is the professional practice of drafting, editing, and preparing scientific documents in healthcare: protocols, clinical study reports, manuscripts, training materials, patient-facing content. The person who does this work, the medical writer, combines scientific knowledge, command of the language, and familiarity with the regulatory, editorial, and ethical standards that govern each type of document.

It's a well-established profession. Professional associations with decades of history represent medical writers and provide training: AMWA (the American Medical Writers Association) in the United States and EMWA (the European Medical Writers Association) in Europe. Its existence answers a simple reality: researchers and clinical teams don't always have the time — and sometimes not the craft either — to turn their data into documents that are clear, correct, and compliant with every formal requirement. That's exactly what the medical writer brings to the table.

• Regulatory writing. The most tightly governed of the three. It covers the documents the industry submits to regulatory agencies (EMA, FDA, AEMPS): clinical trial protocols, clinical study reports (CSRs), investigator brochures, modules of the registration dossier, agency responses and briefing documents. Here creativity barely matters and precision is everything: standardized formats (like the CORE Reference template for CSRs or the CTD format for dossiers), templates, controlled terminology, and strict regulatory deadlines.
• Scientific or publication writing. The kind that carries results to the scientific community: manuscripts for journals, abstracts and congress posters, literature reviews. It's governed by the rules of the publishing world (the ICMJE recommendations, reporting guidelines such as CONSORT or PRISMA depending on the study design, each journal's instructions) and demands, beyond good writing, knowing how to navigate the publication process: choosing a journal, responding to reviewers, managing timelines.
• Educational or lay writing. Training materials for healthcare professionals, continuing medical education (CME) content, patient materials, plain-language content. The challenge here is one of translation: keeping scientific rigor while adapting the register for non-specialist audiences, without sliding into misleading oversimplification or impenetrable jargon.

• Critical appraisal of the scientific literature: understanding a paper, spotting its limitations, and knowing what evidence actually backs each claim.
• Source and reference management: searching well, citing well, and verifying every citation. A manuscript with references that don't say what's attributed to them is a serious problem, more so now that AI-generated drafts are common.
• Knowledge of the standards: ICMJE and reporting guidelines on the editorial side; agency requirements and good clinical practice on the regulatory side.
• Scientific English, because most output is published in English, plus careful command of the local language for everything else.
• Project and author management: coordinating versions, comments, and sign-off from multiple co-authors with impossible schedules is, often, half the job.

You can't talk about medical writing without addressing the question it always raises: if a professional writes the text, whose paper is it? The answer has been well established for years, and it's worth knowing, because it's what separates legitimate practice from the kind that isn't.

The ICMJE recommendations define who can be listed as an author: someone who contributes substantially to the work, takes part in drafting or critically revising the text, approves the final version, and takes responsibility for the whole. A medical writer engaged to draft a document usually doesn't meet all those criteria and therefore doesn't sign as an author; the correct approach is to acknowledge their contribution, along with who funded their work. That's exactly what the GPP 2022 guidelines (Good Publication Practice, the reference standard for industry-sponsored publications) and the joint AMWA–EMWA–ISMPP position statement on the role of the professional medical writer set out.

Ghostwriting — a professional writing the text while their involvement is concealed — is malpractice that editors and the professional associations themselves have flagged for years. The line separating it from legitimate medical writing isn't who types the words, but transparency: declared contribution, declared funding, and real authors who direct the content and take responsibility for it. A professional medical writer working to GPP standards isn't a ghost; they're a recognized specialist named in the document itself.

IN SHORT

The line between legitimate medical writing and ghostwriting isn't who types the words — it's whether the contribution and the funding are disclosed.

• It makes sense to keep it in-house when there's a steady flow of documents of the same type: a company running several active trials on a continuous regulatory calendar can justify its own regulatory writing team, and a scientific society with high output can justify a standing editorial role.
• It makes sense to outsource it when the need is one-off or irregular: the research group publishing two or three papers a year, the hospital trying to turn its results into manuscripts, the journal that needs to shore up the formal quality of what it receives, the small company without a properly resourced medical department. Keeping a senior writer on staff for occasional workload peaks rarely pays off.
