Emerging trends
- Shift from “generic LLMs” to “evidence-grounded” writing (RAG)
- Medical writing is being improved by adding retrieval (RAG) so the model can cite trusted sources (guidance, literature, trial registries) while drafting.
- In a 2025 evaluation of protocol sections, an off-the-shelf LLM scored >80% for relevance and terminology, but only ~40% or less for clinical logic and for transparency/references; with RAG, those weaker dimensions increased to ~80%.
- AI is being positioned as a “first-draft engine” for large, slow documents
- A typical clinical trial protocol can be 50–150+ pages and can take 3–6 months (or longer) to prepare, so the strongest near-term value is draft acceleration plus structured review.
- This pushes workflow redesign toward “draft fast → review harder,” rather than full automation.
- Rapid growth in compliance/governance requirements for AI-generated text
- Regulators are publishing AI guidance focused on credibility, context-of-use, and risk-based assessment when AI outputs support decisions on safety/effectiveness/quality. (Draft guidance dated January 2025).
- As a result, audit trails, source traceability, and documented review steps are increasingly being required in writing workflows.
- Patient-friendly/Plain Language content is becoming a core AI use area
- Studies show AI can improve readability and reduce writer time for plain-language outputs. In a multi-study evaluation, bespoke AI saved medical writers >40% time for creating plain language summary abstracts (PLSAs).
- Health authorities commonly recommend patient materials at 6th–8th grade reading level (used as a benchmark in this work).
- Investment intent is rising, but skill gaps and low current usage remain visible
- A 2024 RAPS-linked survey summary reported 57% of companies planned investment to improve medical writing technology over the next year; however, only ~9–10% were using AI for data extraction/summarization in medical-writing contexts at the time, and 12% were incorporating AI into automated report generation; 53% cited insufficient knowledge to deploy AI.
- This indicates early-stage adoption with strong intent but execution barriers (governance, training, validation).
use cases of AI in medical writing
- Clinical trial protocol drafting and section authoring
- Use: first drafts of objectives, endpoints, eligibility criteria, schedule of activities narrative, and boilerplate sections, followed by SME and QA review.
- Why it fits: protocols are typically 50–150+ pages and can take 3–6 months to prepare.
- Quality note: protocol-section scoring showed weak areas for generic LLMs (≈40% for logic and references), improved to ≈80% with RAG.
- Plain Language Summaries (PLS) and patient-facing scientific explanations
- Use: create plain-language abstracts/summaries from scientific abstracts or CSRs, then medical writer edits for accuracy and tone.
- Impact: bespoke AI reduced time by >40% for PLSA creation in a controlled comparison.
Compliance anchor: target readability often aligns to 6th–8th grade guidance for patient education.
- Clinical documentation support that feeds downstream medical writing
- Use: generate or improve discharge summaries, encounter summaries, and structured notes that later support narratives and reports.
- Evidence: a 2025 scoping review (41 studies) reported that some implementations achieved up to 40% time savings in clinical documentation tasks.
- Regulatory submission writing support with documented governance
- Use: draft responses to authority questions, prepare structured summaries, and standardize language across modules—while keeping strong human approval and traceability.
- Regulatory context: FDA published draft guidance (dated Jan 2025) on using AI to produce information supporting regulatory decision-making.
- Scale signal: FDA (as reported by MedCentral) stated that since 2016, CDER received 500+ submissions with AI components and CBER received 560+ submissions.
- Publication writing assistance (language, rephrasing, structured outlines)
- Use: rephrase paragraphs, improve clarity, create structured outlines, and generate first drafts for non-clinical publication components then verify references and claims.
- Adoption indicator (researchers, not vendors): in a survey of 200 researchers, 11.5% reported using ChatGPT in their research, mainly for rephrasing and finding references.
