The medical communications landscape
What med comms is, its audiences and channels, and the boundary between medical and promotional communication
What medical communications is
Medical communications — often shortened to med comms — is the discipline that plans, creates and delivers scientific and medical content to healthcare professionals, payers, patients and other stakeholders. It operates at the intersection of medical affairs, clinical development and commercial strategy, but it is distinct from each. Medical affairs sets the scientific platform; commercial sets the market strategy; medical communications translates both into materials that are scientifically sound, audience-appropriate and regulation-compliant.
The scope of med comms is broad. It includes publication planning (peer-reviewed manuscripts, congress presentations, systematic reviews), medical education (advisory boards, speaker training, continuing medical education programmes), scientific platforms (disease awareness campaigns, formulary dossiers, health-economic analyses), and digital engagement (medical websites, key opinion leader engagement, social media strategy for medical information). Each channel has its own rules, conventions and regulatory constraints.
What unites all med comms activities is a single principle: the content must be evidence-based. Unlike advertising, which can use emotional appeal and selective emphasis within regulatory limits, medical communications must present clinical evidence accurately, completely and in context. A medical communications strategy that cherry-picks data, omits unfavourable results, or overstates the significance of exploratory analyses is not just poor practice — it may violate regulations governing the promotion of prescription medicines.
The medical communications landscape
The med comms landscape has evolved significantly in the past decade. Digital channels have multiplied the touchpoints between companies and healthcare professionals. Regulatory scrutiny has intensified, particularly around the boundary between medical and promotional communication. Payer audiences have become more important, demanding health-economic evidence alongside clinical efficacy data. And patients — empowered by online information and advocacy groups — have become a direct audience for medical information.
This evolution has changed the skills a medical communicator needs. A decade ago, the core skill was writing a manuscript or a congress poster. Today, the core skill is strategic thinking — understanding how different channels, audiences and messages interconnect to build a coherent scientific narrative that supports the product throughout its lifecycle, from first-in-human data through patent expiry and beyond.
| Audience | Primary channels | Key requirements | Regulatory constraints |
|---|---|---|---|
| Healthcare professionals | Publications, congresses, advisory boards, CME | Scientific rigour, clinical relevance, balanced presentation | Must be non-promotional; fair balance; disclosure of funding |
| Payers | AMCP dossiers, health-economic analyses, formulary submissions | Cost-effectiveness data, budget impact models, real-world evidence | Must use approved claims; health-economic models must be transparent |
| Patients | Patient education materials, disease awareness campaigns, digital content | Plain language, cultural sensitivity, empowerment without alarm | Must not be promotional; health literacy standards; accessibility |
| Regulators | Regulatory documents, labelling, risk communications | Accuracy, compliance, transparency | Subject to full regulatory review and approval |
Publication planning
Strategic publication plans, GPP guidelines, data inventory, publication sequence and authorship ethics
Publication planning
Publication planning is the strategic discipline of deciding what clinical evidence to publish, where, when and how. A publication plan is not a wish list of manuscripts — it is a strategic document that maps the company's clinical data to the journals, congresses and audiences that will have the most scientific impact. Done well, a publication plan ensures that the scientific community has access to the full body of evidence, presented transparently and in a logical sequence.
The foundation of a publication plan is the data inventory. Before deciding what to publish, the writer must catalogue all available data: completed trials, ongoing studies, post-hoc analyses, real-world evidence, health-economic analyses, and any relevant nonclinical data. Each data set is then assessed for its scientific merit, audience relevance and strategic importance.
The plan must address the publication sequence. The primary publication of a pivotal trial typically comes first, followed by secondary analyses (subgroup analyses, quality-of-life data, long-term follow-up), then pooled analyses and real-world evidence. This sequence builds the evidence base methodically — each publication adds to the narrative established by the previous ones.
Good Publication Practice (GPP)
GPP (currently GPP 2022) is the industry standard for responsible, ethical publication of company-sponsored research. It covers authorship criteria, transparency, trial registration, and the disclosure of sponsor involvement. Medical writers who work on publications must know GPP thoroughly — violations can result in retractions, regulatory sanctions, and reputational damage.
Key GPP principles include: all company-sponsored trials should be published regardless of outcome (no selective publication of positive results only); authorship must follow ICMJE criteria (authors must have made substantial contributions, not just hold an organisational title); professional medical writers should be acknowledged; and the sponsor's involvement in the design, conduct and reporting of the study must be transparent.
GPP also addresses the contentious issue of ghost writing. A ghostwritten publication is one where a professional writer contributed substantially but is not acknowledged. GPP prohibits ghost writing unequivocally. The medical writer may draft the manuscript, but they must be listed as a named contributor or acknowledged, and the listed authors must have made substantive intellectual contributions to the work.
| Publication type | Typical journal target | Strategic purpose | Timeline from data |
|---|---|---|---|
| Primary manuscript (pivotal trial) | Top-tier journal (NEJM, Lancet, JAMA) | Establish the core evidence base | 6-12 months |
| Congress abstract/poster | Major disease-area congress | Early scientific awareness; peer feedback | 3-6 months |
| Secondary analysis | Specialty journal | Deepen understanding of specific populations or endpoints | 12-18 months |
| Review article | Review journal or invited | Place the compound in therapeutic context | Post-approval |
| Real-world evidence | Outcomes journal | Demonstrate effectiveness beyond clinical trial setting | 2-3 years post-launch |
A multi-year Publication Strategic Plan translates clinical trial milestones into an ethical, balanced, timely dissemination cascade across peer-reviewed journals and international congresses:
| Trial Lifecycle Phase | Target Publication Deliverable | Governing Guideline & Timing Mandate |
|---|---|---|
| Trial Initiation (Month 0–6) | Trial Design / Rationale Manuscript (with baseline demographics and biomarker methodology). | ICMJE Trial Registration mandate; publish prior to primary trial completion to establish scientific rationale. |
| Primary Database Lock (Month 24) | Late-Breaking Congress Abstract + Simultaneous Primary Landmark Manuscript in Top-Tier Journal (NEJM, Lancet, JAMA). | GPP 2022: Aim for submission within 12–18 months of LPLV (Last Patient Last Visit) to prevent publication delays. |
| Post-Primary (Month 24–36) | Pre-specified Subgroup Analyses (Age, Renal function, Biomarker status), Patient-Reported Outcomes (PRO / QoL), Long-Term Safety Extensions. | EQUATOR Network reporting guidelines (CONSORT-PRO, STROBE). Must pre-specify analyses in original SAP to avoid post-hoc data dredging. |
| Post-Marketing / Launch (Month 36+) | Real-World Evidence (RWE) registries, Health Economic / Cost-Effectiveness models, Plain Language Summaries of Publications (PLSP). | GPP 2022 PLSP guidance; ensure accessibility for patient communities, advocacy groups, and non-specialist clinicians. |
Writing the primary publication
IMRAD for clinical trials, CONSORT compliance, results presentation, and balanced reporting of safety data
Writing the primary publication
The primary publication of a pivotal trial is the single most important deliverable in a medical communications programme. It establishes the evidence base in the peer-reviewed literature, provides the citable reference for all subsequent communications, and shapes how the medical community perceives the clinical evidence. A poorly written primary publication — one that overstates the results, omits important safety data, or uses misleading statistics — can undermine the product's scientific credibility irreparably.
Writing a primary publication requires mastery of the IMRAD format (Introduction, Methods, Results, and Discussion) as applied to a randomised clinical trial. Each section has specific conventions, and top-tier journals enforce them rigorously. The writer must also follow the CONSORT (Consolidated Standards of Reporting Trials) checklist, which specifies the information that must be included in a trial report. CONSORT compliance is a requirement for most major journals.
CONSORT compliance
The CONSORT 2010 statement provides a 25-item checklist for reporting parallel-group randomised trials. Extensions exist for cluster trials, non-inferiority trials, pragmatic trials, and other designs. The medical writer must know which items are mandatory and where they belong in the manuscript.
Key CONSORT items that writers frequently miss include: a structured flow diagram showing enrolment, allocation, follow-up and analysis (CONSORT diagram); pre-specified primary and secondary outcomes with clear definitions of how they were measured; the method of randomisation, including the mechanism of allocation concealment; the type of blinding (participants, care providers, outcome assessors) and a description of the similarity of interventions; all pre-specified analyses including subgroup analyses; and a complete account of all important harms. The last point is critical — a primary publication that emphasises efficacy and underreports safety will be viewed with suspicion by reviewers, agencies and the medical community.
The results section
The results section of a primary publication follows a specific order: participant flow (CONSORT diagram), baseline demographics and clinical characteristics, primary outcome, secondary outcomes, subgroup analyses, and safety. Each result must include the point estimate, the measure of precision (95% confidence interval), and the pre-specified statistical test. P-values are reported for pre-specified hypothesis tests; exploratory analyses should use language that reflects their hypothesis-generating nature.
A critical error in publication writing is presenting post-hoc analyses as if they were pre-specified. If a subgroup analysis was not in the statistical analysis plan, it must be labelled as post-hoc, and the language must reflect the exploratory nature: "The post-hoc analysis suggested a potential trend..." not "The analysis demonstrated a significant benefit in..."
Congress communications
Abstract writing, poster design, oral presentation development, speaker training and Q&A preparation
Congress communications
Medical congresses are the primary venue for disseminating new clinical data to the specialist community. A well-executed congress programme can shape scientific discourse, position a compound in the therapeutic landscape, and generate media coverage that reaches prescribers worldwide. The medical writer's role encompasses abstract preparation, poster development, slide creation, speaker training, and post-congress activities.
Abstract writing for congresses is a distinct skill from manuscript writing. Abstracts are constrained by strict word counts (typically 250-400 words), must include structured sections (background, methods, results, conclusions), and must present results that are final — congress committees reject abstracts based on interim analyses unless specifically invited. The abstract must tell a complete story in the allotted space, which requires ruthless prioritisation of what to include.
Poster development
A scientific poster is a visual medium, not a scaled-down manuscript. The most common error in poster design is cramming manuscript-length text onto a 48×72 inch board. An effective poster uses data visualisation — forest plots, Kaplan-Meier curves, bar charts — as the primary communication tool, with text limited to context, methods summary, and key conclusions.
The writer must understand the visual hierarchy of a poster: the title and conclusion are read from three metres away; the figures are examined from one metre; the methods and fine print are read from 50 centimetres. Design every element for its reading distance. This means large fonts for the title (≥85 pt), medium fonts for section headers (≥36 pt), readable fonts for body text (≥24 pt), and clear, high-contrast figures.
Oral presentation development
Developing an oral presentation for a congress is more than creating slides. The medical writer creates the slide deck, the speaker notes, and often trains the presenter. The slides must tell a visual story — each slide should make one point, supported by one figure or table. A common error is producing text-heavy slides that the speaker reads verbatim. If the audience can read the slide faster than the speaker can present it, the slide has too much text.
The writer must also prepare for the Q&A. Congress presentations of pivotal data will attract challenging questions from the audience. Anticipating these questions — typically about limitations, alternative explanations for the results, and comparisons with competitors — and preparing concise, data-based responses is part of the writer's role.
The scientific platform
Building the evidence-based messaging framework that guides all medical communications activities
The scientific platform
A scientific platform (also called a medical strategy or scientific narrative) is the foundational document that defines how a company talks about its product in scientific and medical contexts. It is not a promotional positioning statement — it is an evidence-based framework that maps the clinical data to the scientific questions the medical community is asking.
The platform typically includes: the disease background (epidemiology, pathophysiology, burden of disease); the current treatment landscape (existing therapies, their limitations, and the unmet medical need); the product's mechanism of action and pharmacology; the clinical evidence (efficacy, safety, and patient-reported outcomes); the product's place in the treatment algorithm; and the key scientific messages, each linked to its supporting evidence.
Every medical communications deliverable — from a congress poster to a medical information letter — should trace back to the scientific platform. This ensures consistency across all channels and audiences. When a new data readout occurs, the platform is updated, and all downstream materials are refreshed to reflect the new evidence.
Key scientific messages
A key scientific message is a concise, evidence-supported statement about the product's clinical profile. Unlike a promotional claim, a scientific message presents data in a balanced way — it may include both the efficacy finding and its limitations. For example, a promotional claim might be "Drug X reduces HbA1c more than Drug Y." A scientific message might be "In the head-to-head COMPARE trial, Drug X demonstrated a statistically significant greater reduction in HbA1c compared with Drug Y (−1.2% vs −0.8%, p<0.001) over 52 weeks; the incidence of hypoglycaemia was similar between groups."
Each key message should be: evidence-based (linked to specific studies and data), balanced (including relevant safety context), differentiated (highlighting what is unique about this product's evidence), and audience-appropriate (adapted for HCPs, payers or patients as needed).
Advisory boards and medical education
Planning legitimate advisory boards, CME development, faculty management and compliance requirements
Advisory boards and medical education
Advisory boards are structured meetings where a sponsor convenes a small group of external experts (typically 8-15) to obtain their scientific advice on specific questions. Unlike promotional speaker programmes, advisory boards are designed to generate input from the advisors — the information flows from the experts to the company, not the other way around. This distinction is critical: a regulatory authority or compliance team will scrutinise whether an advisory board had a legitimate scientific purpose or was a disguised promotional event.
The medical writer's role in advisory boards includes: developing the scientific agenda (the specific questions the company needs answered), creating pre-read materials (background data, published evidence, discussion frameworks), writing discussion guides (structured questions to guide the conversation), and producing the post-meeting report (a comprehensive summary of the advisors' input and its implications for the medical strategy).
Medical education programmes
Medical education encompasses continuing medical education (CME), certified education programmes, and non-certified educational initiatives. The key distinction is whether the programme is certified by an accrediting body (such as ACCME in the US or EACCME in Europe), which imposes strict requirements on content independence, faculty selection, and disclosure of commercial support.
For certified CME, the content must be balanced, evidence-based, and free from commercial bias. The faculty must be independent of the sponsor. The sponsor may provide an educational grant but cannot influence the content. The medical writer who develops CME content must understand these requirements and ensure that the materials meet the accrediting body's standards — not the sponsor's promotional objectives.
Non-certified medical education has more flexibility in content and speaker selection but still must comply with the relevant promotional regulations. The line between education and promotion is policed by regulatory agencies, and a programme that claims to be educational but presents only the sponsor's product in a favourable light will be viewed as disguised promotion.
Payer communications and health economics
Value dossiers, QALYs, ICERs, budget impact models, indirect treatment comparisons and HTA submissions
Payer communications and health economics
Payer communications is the branch of medical communications that addresses health technology assessment bodies, formulary committees, insurance companies and government healthcare systems. These audiences make decisions about whether a drug will be reimbursed — and at what price — based on evidence of clinical value, cost-effectiveness and budget impact.
The medical writer who works in payer communications must understand health economics: concepts like quality-adjusted life years (QALYs), incremental cost-effectiveness ratios (ICERs), budget impact models, indirect treatment comparisons (ITCs), and network meta-analyses (NMAs). These are not abstract concepts — they determine whether patients in an entire healthcare system will have access to a new treatment.
The value dossier
A value dossier (also called an AMCP dossier in the US, or a health technology assessment submission in the EU/UK) is a comprehensive document that presents the clinical, economic and humanistic evidence supporting a product's value. The structure follows established templates: the AMCP Format for Formulary Submissions in the US, and HTA body-specific templates (NICE in the UK, G-BA in Germany, HAS in France) in Europe.
The value dossier typically includes: the disease and treatment background, the clinical evidence (efficacy, safety, comparative effectiveness), the economic evidence (cost-effectiveness analysis, budget impact analysis), patient-reported outcomes, and a summary of the product's overall value proposition. The evidence must be presented transparently, with full disclosure of assumptions, limitations and sensitivity analyses.
A critical component of the value dossier is the indirect treatment comparison or network meta-analysis. When head-to-head trials against all relevant comparators are not available — which is the norm — the writer must present ITC or NMA results that estimate comparative effectiveness across the treatment landscape. These analyses have specific methodological requirements and limitations that the writer must present honestly.
Risk communications and crisis management
Safety signals, DHCP letters, label updates, media responses and crisis communication principles
Risk communications and safety messaging
Risk communication is the branch of medical communications that deals with safety signals, product withdrawals, regulatory safety actions, and crisis management. It is the highest-stakes area of med comms — the language used in a Dear Healthcare Professional letter, a label update, or a media statement can affect prescribing behaviour, patient safety and public trust.
Effective risk communication follows specific principles: it is timely (the first response sets the narrative), accurate (errors in safety communications are catastrophic), balanced (acknowledging the risk without causing unnecessary alarm), actionable (telling the recipient what to do), and transparent (disclosing what is known, what is not known, and what is being done to find out).
The medical writer in a risk communication scenario must work under extreme time pressure while maintaining the highest standards of accuracy. A Dear Healthcare Professional (DHCP) letter — also called a Dear Doctor letter — typically must be drafted, reviewed, approved and distributed within days of a regulatory request. The writer must distil complex safety data into clear, actionable language that a busy clinician can understand and act on immediately.
The Dear Healthcare Professional letter
The DHCP letter is the primary vehicle for communicating important safety information to prescribers. It follows a standard structure: a header identifying it as an important safety communication (often with the product name and the nature of the risk), the new safety information, the recommended actions for prescribers, contact information for medical inquiries, and the regulatory agency's role. The tone must be urgent but not alarmist — the goal is to change prescribing behaviour, not to cause panic.
Key elements of an effective DHCP letter include: a clear subject line that names the product and the risk; a concise first paragraph that states what has changed and why the letter is being sent; the clinical details of the safety signal (what was observed, in how many patients, over what time period); the recommended monitoring or prescribing changes; and where to report additional cases.
Digital medical communications
Medical information websites, social media strategy, digital engagement, regulatory compliance in digital channels
Digital medical communications
Digital channels have transformed medical communications. Healthcare professionals increasingly access medical information through online platforms, social media, and mobile applications. Patients research their conditions, treatments, and clinical trials online. Payers use digital tools to evaluate cost-effectiveness data. The medical communicator must understand how to use these channels effectively while maintaining regulatory compliance.
The regulatory framework for digital medical communications is still evolving. The FDA has issued guidance on internet and social media promotion, but many questions remain unresolved. Key principles include: all digital content is subject to the same regulatory requirements as print content; social media posts that mention a product by name must include fair balance (risk information alongside benefit claims); unsolicited requests for medical information received through digital channels may be answered with off-label information under specific conditions; and user-generated content on company-sponsored platforms creates monitoring and reporting obligations.
Medical information websites
A medical information website serves as the company's digital presence for scientific and medical content. Unlike a promotional website, a medical information site presents clinical data, prescribing information, safety data, and educational resources without promotional framing. The design must clearly separate medical from commercial content, and the content must be regularly updated to reflect the current evidence.
Key considerations for medical information websites include: audience segmentation (HCP-only content should be behind a professional verification gate; patient content should meet health literacy standards); content governance (who reviews and approves content, how often is it updated, and how are outdated materials archived); adverse event reporting (the site must provide a mechanism for reporting adverse events, and the company must monitor the site for potential safety reports); and regulatory compliance (all content must be consistent with the approved labelling).
Social media and digital engagement
Social media presents unique challenges for medical communications. The character limits of platforms like Twitter (X) make it difficult to include fair balance alongside benefit statements. The real-time nature of social media means that off-label discussions, adverse event reports, and misinformation can emerge rapidly. The viral nature of social media means that a single poorly worded post can reach millions of healthcare professionals and patients within hours.
Effective social media strategy for medical communications requires: clear internal policies on what can and cannot be posted; a rapid response process for addressing misinformation or adverse event reports; a monitoring system that captures relevant conversations; and training for anyone who posts on behalf of the company. The medical writer may be involved in developing social media content, reviewing posts for compliance, and drafting responses to medical inquiries received through social channels.
The integrated communications plan
Audience mapping, channel strategy, timeline development, resource planning and impact measurement
The integrated medical communications plan
An integrated medical communications plan (IMCP) is the strategic document that coordinates all medical communications activities across channels, audiences and timelines. It is the master plan that ensures every publication, congress presentation, advisory board, medical education programme, payer dossier and digital initiative works together to build a coherent scientific narrative.
The IMCP typically covers a 12-36 month period and includes: the strategic context (disease landscape, competitive environment, regulatory timeline), the core scientific messages (from the scientific platform), the audience strategy (who needs to hear what, and when), the channel strategy (which channels reach which audiences most effectively), the activity timeline (a Gantt chart showing all planned activities and their dependencies), the resource plan (internal writers, agency partners, budgets), and the measurement framework (how success is defined and tracked).
Audience mapping and channel strategy
Effective audience mapping goes beyond the simple categories of "HCPs, payers, patients." It identifies specific segments within each audience and the channels that reach them most effectively. For HCPs, this means distinguishing between early adopters (who attend congresses and read primary literature), mainstream prescribers (who rely on guidelines and peer influence), and specialists in adjacent fields (who may refer patients). For payers, it means distinguishing between national HTA bodies, regional formulary committees, and individual hospital pharmacy and therapeutics committees.
Channel strategy matches each audience segment to its preferred information channels. Early-adopter HCPs are reached through primary publications and congress presentations. Mainstream prescribers are influenced by guidelines, CME programmes, and peer recommendations. Payers require value dossiers, budget impact analyses, and real-world evidence. Patients access information through patient education materials, disease awareness campaigns, and online resources.
Measuring impact
Measuring the impact of medical communications is both essential and challenging. Traditional metrics — number of publications, congress presentations, advisory boards — measure activity, not impact. More meaningful metrics include: publication impact (citations, altmetric scores, downloads), awareness and knowledge change (measured through surveys before and after specific activities), guideline inclusion (whether the product is mentioned in treatment guidelines), formulary access (the proportion of target markets where the product is on formulary), and prescriber behaviour change (measured through prescription data analysis).
The challenge is attribution — it is difficult to isolate the impact of a single publication or advisory board from the many other factors that influence prescribing behaviour. The best measurement frameworks use a combination of leading indicators (awareness, knowledge, stated intent) and lagging indicators (prescriptions, market share) to build a picture of communications effectiveness over time.
Patient communications
Health literacy, plain language principles, patient education materials, visual design and audience testing
Patient communications
Patient communications is the discipline of creating medical information for patients, caregivers and the public. It requires a fundamentally different skill set from writing for healthcare professionals. The audience may have no medical training, may be in emotional distress, may have limited health literacy, and may be making life-altering decisions based on what they read. The writer's responsibility is to be accurate, clear, compassionate and empowering — never paternalistic, alarmist or dismissive.
Health literacy is a central concern. Research consistently shows that a large proportion of adults have limited health literacy — they struggle with medical terminology, numerical concepts (risk percentages, dosing), and the structure of healthcare systems. Patient materials must be written at a reading level appropriate for the target audience (typically 6th-8th grade reading level in the US), use plain language, and present numerical information in formats that aid comprehension (such as natural frequencies: "5 out of 100 people" rather than "5%").
Plain language principles
Plain language is not about dumbing down — it is about clear communication. The principles include: use short sentences (15-20 words average); use active voice; use common words instead of medical jargon (but define technical terms when they are unavoidable); use headings and bullet points to break up dense text; and present the most important information first.
Visual design is equally important. Patient materials should use readable fonts (12-14 pt minimum), adequate white space, clear visual hierarchy, and culturally appropriate images. Infographics can be highly effective for presenting risk-benefit information, treatment timelines, and decision-support tools. The writer must collaborate with designers to ensure that the visual presentation supports the written content.
Testing patient materials with the target audience is best practice. What seems clear to a medical writer may be confusing to a patient. Methods include readability formulas (Flesch-Kincaid, SMOG), cognitive interviews (where patients read the material aloud and explain their understanding), and usability testing (where patients use the material to complete a task, such as finding the dose information).
Capstone: lifecycle strategy
An integrated capstone developing a full medical communications strategy from pre-approval through post-launch
Capstone: integrated strategy development
This capstone module challenges you to synthesise everything you have learned into a comprehensive medical communications strategy. The strategy must address multiple audiences (HCPs, payers, patients), multiple channels (publications, congresses, digital, education), multiple phases (pre-approval, launch, post-launch), and multiple regulatory environments (US, EU, rest of world).
A successful strategy starts with three questions: What does the evidence show? Who needs to know? And how will they receive it? The first question is answered by the clinical data and the scientific platform. The second is answered by audience mapping and needs assessment. The third is answered by channel strategy and tactical planning.
The lifecycle perspective
Medical communications is not a launch activity — it spans the entire product lifecycle. Pre-approval communications establish the scientific foundation: publications, congress data presentations, and disease awareness campaigns that educate the community about the unmet need. Launch communications translate the clinical evidence into actionable information for prescribers, payers and patients. Post-launch communications build the evidence base with real-world data, long-term follow-up, and comparative effectiveness studies.
The lifecycle perspective also means planning for challenges. Every product will face competitive threats (new entrants, generic competition), safety signals (post-marketing reports, REMS requirements), and evidence gaps (populations not studied in clinical trials, long-term outcomes). The communications strategy must anticipate these challenges and include contingency plans.
Ethics and professionalism
The medical communications professional occupies a position of trust. Healthcare professionals rely on the accuracy and completeness of the information they receive. Patients trust that the materials they read are balanced and honest. Regulatory agencies trust that promotional regulations are being followed. Maintaining this trust requires unwavering commitment to scientific integrity, transparency, and ethical conduct.
This commitment is tested regularly. Commercial pressures may push for more favourable data presentation. Tight timelines may tempt shortcuts in quality control. Competitive dynamics may encourage overstating results or understating risks. The medical communicator's professional identity is defined by the choices made in these moments — choosing accuracy over convenience, balance over spin, and transparency over selective presentation.
Reporting guidelines and registration
Every study type has a reporting guideline. Every interventional trial must be registered. These are not suggestions — they are conditions of publication. This module teaches you to apply both.
Which guideline applies
The EQUATOR Network maintains over 500 reporting guidelines. In practice, six cover most of what a medical communications writer encounters:
STROBE — observational studies (cohort, case-control, cross-sectional). 22 items. The most common gap: not reporting how missing data were handled.
PRISMA — systematic reviews and meta-analyses. 27 items plus flow diagram. Updated in 2020 with new emphasis on risk-of-bias assessment and certainty of evidence.
STARD — diagnostic accuracy studies. 30 items. Critical for companion diagnostics and biomarker studies.
SPIRIT — clinical trial protocols. 33 items. Required by many registries and funders before the study begins.
CARE — case reports. 13 items. Often overlooked but increasingly required by journals that accept case reports.
The items most often missing
Editors and peer reviewers see the same gaps repeatedly. Knowing what is most often missing lets you catch it before submission:
STROBE: (1) handling of missing data, (2) sensitivity analyses, (3) how the study size was determined, (4) generalisability discussion.
PRISMA: (1) full search strategy for at least one database, (2) risk-of-bias assessment per study, (3) certainty of evidence (GRADE), (4) protocol registration number.
Trial registration
Since 2005, the ICMJE has required prospective registration of all interventional trials as a condition of publication. Registration means committing — before the first participant is enrolled — to the primary endpoint, the sample size, and the analysis plan. This prevents outcome switching and selective reporting.
When: before or at the time of first patient enrolment. Retrospective registration is allowed by some journals but must be disclosed and justified.
What to check: the registered primary endpoint matches the manuscript's primary endpoint. If the analysis population or statistical method changed after registration, the manuscript must acknowledge this and explain why. A discrepancy between the registry and the manuscript is the single most common reason for retraction of the primary endpoint claim.
Risk: journalists, regulators, and competitors will read both versions. If the subgroup that disappeared is the one where the drug did not work, this looks like selective reporting — even if the change was made for legitimate statistical reasons. A post-publication investigation by COPE or the journal's ethics committee can follow. The practical rule: never remove an analysis that appeared in a preprint without explaining why in the final version.
Research integrity and citation accuracy
Plagiarism detection, image manipulation, citation errors, and authorship disputes — the integrity issues that end careers and retract papers. A medical communications writer is often the last line of defence.
Text reuse: three categories
Not all text reuse is plagiarism, but all text reuse must be handled correctly:
Plagiarism: using someone else's text without attribution. In medical writing, this most often happens when a writer copies a competitor's methods description or a textbook definition. Always paraphrase and cite.
Redundant publication: publishing the same dataset in multiple journals. This is distinct from plagiarism — the text may be entirely rewritten, but the data overlap is the problem. Check with the sponsor whether any of the data have been published elsewhere, including as congress abstracts.
Image integrity
Image manipulation is the fastest-growing reason for retraction. As a writer, you may not create the figures — but you must know what to check:
Microscopy images: check for duplicated panels (same image used for different conditions), brightness/contrast adjustments that change the interpretation, and cropping that removes relevant context.
Bar charts: check that error bars match the stated measure (SD vs. SEM vs. 95% CI) — SEM makes differences look larger than SD. Dot plots are preferable because they show the actual data distribution.
Flowcharts: check that the numbers add up at every branch. The CONSORT flow diagram is the most commonly error-prone figure in clinical manuscripts.
Citation accuracy
Studies consistently find that 25–40% of references in published papers contain at least one error, and 5–10% have errors serious enough to make the reference unverifiable. As the writer who compiles the reference list, you can prevent most of these.
Reference errors: wrong author names, wrong volume/page, wrong year. These prevent the reader from finding the paper. Use DOIs where available — they survive journal re-pagination.
Citation bias: systematically citing only studies that support the desired conclusion. Check: are there important studies on the other side that the authors have not cited?
String citations: a claim supported by "[1-7]" where only reference 3 actually supports it. Verify each reference in a string citation individually.
Medical writers managing author steering committees must uphold strict authorship ethics to eliminate ghostwriting and honorary (guest) authorship:
| ICMJE Authorship Criterion | Operational Industry Compliance Standard | CRediT (Contributor Roles Taxonomy) Mapping |
|---|---|---|
| 1. Substantial Contributions | Direct role in trial conception, protocol design, data acquisition, or analysis/interpretation of statistical data. | Conceptualization, Methodology, Formal Analysis, Investigation. |
| 2. Drafting or Critical Revision | Substantive intellectual contribution to drafting the manuscript or critically revising it for important intellectual content. | Writing – Original Draft, Writing – Review & Editing. |
| 3. Final Approval | Explicit written sign-off approving the final version to be published (recorded via timestamped tracking). | Supervision, Project Administration. |
| 4. Accountability Agreement | Agreement to be accountable for all aspects of the work in ensuring that questions related to accuracy or integrity are resolved. | Validation, Data Curation. |
| Professional Medical Writer | Professional medical writers who draft the manuscript under author direction are acknowledged with funding disclosure (NOT listed as co-authors unless meeting all 4 criteria). | Acknowledgment Section: "Medical writing support was provided by [Name, Degree] of [Agency/Company], funded by [Sponsor] in accordance with GPP 2022 guidelines." |
Error 2: Reference 4 is a secondary source — it does not provide independent data, it merely cites references 1 and 2. Citing it alongside the primary sources is redundant and misleading (it looks like four independent data points when there are really two).
Corrected claim: "The incidence of grade ≥3 hepatotoxicity with this class of agents has been reported as 7% and 12% in pivotal trials [1,2]." Reference 3 can be cited separately for all-grade incidence, and reference 4 should be dropped or cited only for its review conclusions.
Step 2 (15 min): For each factual claim in the text that cites a reference, open the cited paper and verify the specific number or statement. Prioritise claims that are central to the argument (primary endpoint results, safety figures, prevalence data).
Step 3 (10 min): Check string citations — any "[1-4]" or "[5,7,12]" cluster. Verify that each reference in the string actually supports the specific claim, not just the general topic.
Step 4 (5 min): Look for secondary citations disguised as primary sources (review articles cited alongside the papers they review). Flag any reference you cannot access — if you cannot verify it, note this for the author.
Step 5 (5 min): Spot-check formatting consistency — author name format, journal abbreviations, DOIs present where available.
Total: approximately 40 minutes for 30 references. This seems slow, but it catches an average of 3–4 errors per manuscript that would otherwise reach peer review.
The executive: reviewing the protocol satisfies criterion 1, but if they did not draft or critically revise the manuscript (criterion 2), they do not qualify. They should be acknowledged, not listed as an author. Listing them is gift authorship.
The statistician: running all analyses satisfies criterion 1. Even though she declines authorship, if the sponsor lists her, she must also satisfy criteria 2–4. Her refusal is a problem because someone who ran all the analyses and is not acknowledged anywhere creates a transparency gap. The correct approach: either she reviews the statistical content of the manuscript (satisfying criterion 2) and becomes an author, or she is named in the acknowledgements with her specific contribution ("conducted the statistical analyses").
Journal selection and corrections
Choosing the right journal, spotting predatory publishers, and knowing how corrections and retractions work — the quality-control layer that protects the publication record.
The ten-minute journal check
Before recommending or agreeing to submit to any journal, run these five checks:
2. Listed in DOAJ? For open-access journals, the Directory of Open Access Journals verifies editorial standards. Absence from DOAJ for an OA journal is a warning sign.
3. Member of COPE? The Committee on Publication Ethics requires members to follow ethical guidelines for handling misconduct, corrections, and retractions.
4. Realistic review timeline? Peer review in under two weeks for a clinical manuscript is a red flag. Median review time for legitimate journals is 2–4 months.
5. Editorial board verifiable? Search three names from the editorial board. If they are real academics in the relevant field, the journal passes. If the names return no academic profile, or the people listed deny involvement, it is predatory.
Corrections and retractions
Published errors are inevitable. How they are handled separates good-faith science from misconduct:
Corrigendum (author error): an error in the submitted manuscript — a wrong number, a mislabelled figure, an incorrect reference. The authors submit a correction notice describing exactly what changed and whether the conclusions are affected.
Expression of concern: the journal has reason to doubt the integrity of the work but has not completed its investigation. The paper remains available but flagged. This can take months or years to resolve.
Retraction: the paper is withdrawn from the scientific record. Reasons include data fabrication, plagiarism, ethical violations, or errors so fundamental that the conclusions are invalid. The retracted paper remains online with a "RETRACTED" watermark — it is not deleted.
Scenario B: A co-author is found to have fabricated the patient-reported outcome data for 30% of the study population. The clinical endpoints are unaffected.
Scenario C: The corresponding author's institution informs the journal that it has opened a misconduct investigation, but the investigation is not yet complete.
Scenario B: Retraction. Data fabrication in any part of the study undermines the integrity of the entire paper, even if other endpoints are unaffected. The fabricated PRO data supported secondary claims, and readers cannot trust the remaining data when a co-author has been shown to fabricate. Partial retraction is sometimes used but is controversial — most journals would retract the entire paper.
Scenario C: Expression of concern. The journal does not yet know whether misconduct occurred, so retraction is premature. But readers deserve to know the paper is under investigation. The expression of concern is published now, and the journal waits for the institutional investigation to conclude before deciding on retraction or clearance.
Sign 2: The manuscript uses tortured phrases — unusual synonyms generated by paraphrasing software to evade plagiarism detection (e.g., "sham composing" for "ghostwriting", "anaerobic film" for "biofilm"). These are detectable by reading the text aloud.
Sign 3: The author list includes researchers from institutions in different countries who have no prior co-publication history, the hospital names in the ethics approval are unverifiable, and the corresponding author uses a non-institutional email address.
If you encounter these signs, you should decline the project and, if employed by an agency, inform your manager. Legitimate medical communications agencies do not participate in paper mill operations.
Publication standards capstone
A full pre-submission quality check: reporting guideline compliance, registration verification, reference accuracy, and integrity screening — applied to a realistic manuscript.
Authors: Dr. A (dermatologist, study investigator), Dr. B (medical writer at ABC Agency, listed as author), Dr. C (VP Medical Affairs at sponsor, listed as senior author), Dr. D (statistician who ran all analyses, not listed as author but acknowledged).
Conflict of interest: Dr. A declares speaker fees from the sponsor. Drs. B and C declare no conflicts. Trial registration: NCT04XXXXXX (registered 3 months after first patient enrolled).
Abstract: "This randomised, double-blind trial demonstrated that Compound X is superior to placebo (PASI 90 response 68% vs 12%, p<0.001)." No trial registration number in abstract. No mention of primary endpoint in abstract methods.
Methods: "Patients were randomised 2:1 using an interactive web response system. The primary endpoint was PASI 90 at Week 16." CONSORT checklist not submitted. No flow diagram. Randomisation sequence generation method not described. Allocation concealment not described.
Results: "240 patients were randomised (160:80). The mITT population (n=228) was used for the primary analysis." Registered primary endpoint on ClinicalTrials.gov: PASI 75 at Week 12. No mention of the endpoint change in the manuscript.
Discussion: "Our results prove that Compound X is the most effective treatment available for plaque psoriasis." No comparison with other biologics was conducted in this trial. References [4] and [7] support this claim — reference [4] is a narrative review by Dr. C, reference [7] is an unpublished poster abstract from a sponsor symposium.
Figures: Figure 2 shows PASI response curves. The y-axis starts at 40% instead of 0%, visually exaggerating the treatment difference.
1. Retrospective registration — the trial was registered 3 months after the first patient was enrolled, violating the ICMJE requirement for prospective registration. This must be disclosed in the manuscript.
2. Endpoint switching without disclosure — the registered primary endpoint is PASI 75 at Week 12, but the manuscript reports PASI 90 at Week 16. This is the most serious violation: it looks like outcome switching. The original endpoint must be reported and the change justified.
Authorship (2)
3. Undisclosed medical writer authorship — Dr. B is a medical writer at an agency but is listed as an author with no disclosure of their role or employment. ICMJE and GPP4 require disclosure of medical writing support. If Dr. B meets ICMJE criteria, the agency affiliation and funding must be disclosed. If not, they should be acknowledged, not listed.
4. Statistician excluded from authorship — Dr. D ran all analyses (criterion 1) but is only acknowledged. If they also reviewed the statistical content (criterion 2), they should be an author. Their exclusion while a VP who may not have drafted anything is listed as senior author suggests gift authorship.
Conflicts of interest (1)
5. Dr. C declares no conflicts — as VP Medical Affairs at the sponsor company, Dr. C has an inherent financial conflict that must be disclosed. Declaring "no conflicts" here is false.
Reporting guideline (2)
6. No CONSORT checklist or flow diagram — both are required for any RCT manuscript. Most journals will desk-reject without them.
7. Randomisation and allocation concealment not described — two of the most commonly missing CONSORT items. Who generated the sequence? How was it concealed? The IWRS mention is not sufficient.
Claims and references (2)
8. "Most effective treatment available" — this claim has no basis in a placebo-controlled trial that did not include an active comparator. It is an overclaim that no peer reviewer would accept.
9. Weak reference support — reference [4] is by a conflicted author (Dr. C), and reference [7] is an unpublished poster — neither supports a superlative claim about efficacy ranking.
Figure integrity (1)
10. Truncated y-axis — starting at 40% instead of 0% exaggerates the visual difference between arms. This is a form of figure manipulation. The y-axis must start at 0%, or a break must be clearly marked.
Scoring: 8–10 = pass, you can run a pre-submission standards check independently. 5–7 = review modules 4.1 and 4.2 before your next submission. Under 5 = repeat Part 4 from the beginning.
