How to Write a BMJ Cover Letter That Works with Open Peer Review
BMJ doesn't just send your paper to academic experts. It also sends it to patient and public reviewers who read your work with completely different eyes. Your cover letter needs to speak to both audiences, and that changes how you frame everything.

Your BMJ cover letter won't just be read by an editor and two academic reviewers. It'll also be read by patient and public reviewers who aren't evaluating your methodology. They're evaluating whether your research matters to real people.
That's what makes BMJ different from every other journal in the "Big 4" of general medicine. NEJM, The Lancet, and JAMA all use traditional peer review with academic experts only. BMJ adds patient and public reviewers alongside those experts, and it does it all under open peer review, where reviewer names are disclosed to authors and published with accepted papers. These aren't quirks. They're the lens through which editors decide what belongs in the journal. If your cover letter doesn't account for both, you're writing for the wrong audience.
What BMJ Actually Wants in a Cover Letter
BMJ prioritizes research that improves decision making in clinical practice, health policy, and medical education. The journal's impact factor sits around 42.7, it accepts roughly 4.9-7% of research articles, and about half of all submissions are desk-rejected before they ever reach a reviewer. Desk decisions come fast, typically within 3-5 business days. That speed tells you something: editors aren't agonizing. They're scanning for immediate signals of fit.
The cover letter is one of those signals. BMJ editors are looking for three things:
A finding that changes clinical decisions. Not a finding that's statistically interesting. Not a finding that extends the literature. A finding that a general practitioner, hospitalist, or policymaker would act on. If the primary audience for your result is subspecialists, BMJ isn't the right venue. Consider a BMJ specialty journal instead.
International relevance. BMJ is a British journal with a global readership. Your research can't be useful only in the UK context or only in one healthcare system. The finding needs to translate across settings. If your intervention depends on infrastructure that exists in 12 countries, say so, but also say why it matters to the other 183.
Clarity for non-specialist readers. This is where the patient reviewer model matters. Your cover letter sets the tone for how accessible your paper is. If you can't explain the clinical relevance without jargon in the cover letter, editors will wonder whether the paper itself has the same problem.
The Patient Reviewer Factor
Most authors don't think about patient reviewers when writing their cover letter. That's a mistake, because the patient reviewer model shapes what BMJ editors are looking for at every stage.
Here's what happens after your paper passes the desk screen. BMJ assigns at least two expert peer reviewers and, for most research articles, one or more patient/public reviewers. The expert reviewers evaluate methodology, analysis, and scientific validity. The patient reviewers evaluate whether the research question matters to patients, whether the outcomes are patient-centered, and whether the paper is written accessibly enough for informed non-specialists.
This is fully open review. Reviewers know who you are, and you'll know who they are. Their comments are published alongside accepted papers. That transparency changes the dynamic. Reviewers tend to be more constructive and more careful because their names are attached.
What this means for your cover letter: frame your finding in terms of patient outcomes and clinical decisions, not just scientific contribution. If your trial showed a reduction in a surrogate endpoint, you need to connect that to something patients experience. "A 15% reduction in HbA1c" is a laboratory number. "Fewer patients progressing to insulin dependence" is something a patient reviewer will understand and care about.
BMJ Cover Letter Template
This template is structured for BMJ's specific expectations. Adapt the content, but keep the architecture.
Dear BMJ Editors,
We submit our [study type], "[Title]," for consideration as a Research
Article in The BMJ.
[Primary finding: one sentence with the main result and a specific number.
Example: "In a pragmatic cluster-randomized trial across 42 primary care
practices in six countries, structured medication reviews by pharmacists
reduced adverse drug events by 31% over 12 months compared to usual care
(RR 0.69, 95% CI 0.58-0.82)."]
[Clinical relevance: two sentences connecting the finding to clinical
decisions and patient outcomes. Example: "This result provides evidence
for embedding pharmacist-led reviews into routine primary care, a model
currently recommended in UK NICE guidelines but lacking international
trial evidence. For the estimated 400 million adults on polypharmacy
globally, this approach could prevent millions of adverse drug events
annually."]
[Journal fit: one sentence. Example: "The cross-country design, direct
applicability to general practice, and patient-centered primary outcome
make The BMJ the appropriate venue for this work rather than a pharmacy
or pharmacology specialty journal."]
[Pre-submission inquiry reference, if applicable: "We received a positive
response to our pre-submission inquiry (reference number) on [date]."]
[Compliance: one sentence. Example: "The trial is registered at
ISRCTN (ISRCTNXXXXXXXX), received ethics approval from [institution],
and we report per CONSORT guidelines. Individual participant data will
be available upon reasonable request."]
All authors have approved the manuscript and it is not under consideration
elsewhere. We have no competing interests to declare [or: competing
interests are declared in the manuscript].
Sincerely,
[Corresponding author name and affiliation]
That template runs about 250-300 words with real content. Keep it under one page.
The Pre-Submission Inquiry: Use It
BMJ offers something most top journals don't make easy: a formal pre-submission inquiry process. You send your abstract and a brief cover letter, and editors tell you whether they see potential fit before you prepare a full submission.
Given that roughly 50% of research articles are desk-rejected, the pre-submission inquiry is worth your time. A positive response doesn't guarantee acceptance, but it means at least one editor thought the topic and scope fit BMJ. A negative response saves you the effort of formatting a full submission to BMJ's specifications and lets you redirect to another journal faster.
Your pre-submission inquiry cover letter should be shorter than the full submission letter. Two paragraphs: the finding with a number, and one sentence on why BMJ rather than a specialty journal. That's it. Don't write a full cover letter for an inquiry.
BMJ vs. Other Top Medical Journals: What's Different
Understanding how BMJ's review process and editorial expectations differ from peer journals helps you calibrate your letter. Don't recycle a cover letter written for NEJM or The Lancet.
Feature | BMJ | NEJM | The Lancet | JAMA |
|---|---|---|---|---|
Peer review model | Open (names disclosed) | Single-blind | Single-blind | Single-blind |
Patient/public reviewers | Yes, for most research | No | No | No |
Pre-submission inquiry | Yes, encouraged | Yes, but selective | Not formal | No |
Desk decision speed | 3-5 business days | 1-2 weeks | 2-3 weeks | 5-10 business days |
Acceptance rate | ~4.9-7% | ~5% | ~4-5% | ~5% |
Impact factor | ~42.7 | ~176.1 | ~42.7.9 | ~55.0 |
Submission system | ScholarOne | Editorial Manager | Editorial Manager | Manuscript Central |
Editorial emphasis | Clinical practice + policy + education | Practice-changing clinical evidence | Global health impact + policy | Clinical relevance + public health |
The open review model is BMJ's most distinctive feature. At NEJM, The Lancet, and JAMA, reviewers are anonymous. At BMJ, everyone's name is on the record. This tends to produce more measured, constructive reviews, but it also means your paper needs to be solid enough that reviewers are comfortable putting their name on a recommendation to publish it.
Common Mistakes in BMJ Cover Letters
These patterns come up repeatedly and they'll hurt your chances.
Mistake 1: Writing for specialists. BMJ is a general medical journal. If your cover letter requires subspecialty knowledge to understand the significance of your finding, you're writing for the wrong audience. The GP reading your paper should understand why it matters without needing a fellowship in your field. The patient reviewer definitely should.
Mistake 2: Ignoring the clinical epidemiology angle. BMJ uses a clinical epidemiology editor to assess manuscripts alongside the subject editors. Your methods section will get serious scrutiny. If your cover letter oversells the finding while glossing over design limitations, the epidemiology editor will notice the gap. Acknowledge your study design clearly. A well-designed pragmatic trial impresses BMJ more than a mechanistic study with perfect controls.
Mistake 3: UK-only framing. BMJ is published in the UK, and it's tempting to frame your finding in terms of NHS relevance. But BMJ's readership is international, and editors want research with broad applicability. If your paper involves UK-specific policy or healthcare infrastructure, your cover letter needs to explain why the findings transfer to other settings.
Mistake 4: Not using the pre-submission inquiry. With a 50% desk-rejection rate, submitting a full manuscript without testing the waters first is a gamble. The pre-submission inquiry exists to prevent wasted effort. Use it.
Mistake 5: Forgetting that reviewers will see your name. Open peer review means no anonymity in either direction. Don't overstate your findings or make claims your data can't support. Reviewers are less likely to let exaggerations slide when their critique is published with their name attached. Keep the cover letter honest and precise.
What Makes BMJ Editors Keep Reading
The difference between a cover letter that gets desk-rejected and one that reaches review often comes down to one thing: whether you've framed the finding as a decision. Not a contribution to knowledge. A decision.
BMJ editors are asking: "If we publish this, what will a doctor, a policymaker, or a patient do differently?" Your cover letter needs to answer that question explicitly. Not "these findings have implications for clinical practice." That's a placeholder sentence that communicates nothing. Instead: "This trial provides the first randomized evidence supporting pharmacist-led medication reviews in primary care, a practice currently implemented in three countries without trial-level evidence."
Name the decision. Name who makes it. Name what changes. That's what gets BMJ editors past the first paragraph.
Before submitting, run your manuscript through a pre-submission review to catch formatting gaps, missing declarations, and structural issues that could trigger a desk rejection independent of your cover letter. BMJ's clinical epidemiology editor will scrutinize your methods rigorously. Better to catch problems before they do.
