NEJM Pre-Submission Checklist: Is Your Paper Ready for the World's Most Cited Medical Journal?
NEJM desk rejects ~90% of submissions within 2 weeks. Before you submit, verify these 12 items covering clinical impact, trial registration, statistical rigor, and what editors screen for first.

How to use this page well
These pages work best when they behave like tools, not essays. Use the quick structure first, then apply it to the exact journal and manuscript situation.
Question | What to do |
|---|---|
Use this page for | A working artifact you can actually apply to the manuscript or response package. |
Start with | Fill the template with real manuscript-specific details instead of leaving it generic. |
Common mistake | Copying the structure without tailoring the logic to the actual submission. |
Best next step | Use the artifact once, then cut anything that does not affect the decision. |
Decision cue: NEJM receives thousands of submissions per year and desk rejects roughly 90% of them within two weeks. Of the ~10% that reach peer review, another 50% are rejected after review. The overall acceptance rate is under 5%. These numbers are not meant to discourage you. They are meant to emphasize that a submission to NEJM without thorough preparation is almost certainly a waste of 2 to 4 weeks. This checklist covers what NEJM editors actually evaluate so you can identify problems before they become a 2-week desk rejection.

The 12-point NEJM pre-submission checklist
Clinical impact
1. Does the finding change how physicians care for patients?
This is NEJM's threshold question. Not "is this scientifically interesting?" but "will doctors treat patients differently after reading this?" Papers that clear the desk tend to be large, well-designed randomized trials with definitive results on clinically important endpoints. The finding must be large enough in magnitude to affect real treatment decisions, not just statistically significant.
2. Is the clinical implication stated in the first paragraph of the abstract?
NEJM editors scan hundreds of abstracts. If the clinical consequence is buried in the last sentence, the first impression is weaker. The abstract should open with the clinical problem and state the practice-changing finding within the first three sentences.
3. Would this finding be discussed at hospital grand rounds within a week of publication?
This is an informal but useful test. If the result would generate immediate discussion among clinicians across specialties, it has NEJM-level impact. If it would mainly interest researchers in one specialty, a specialty journal is a better target.
Study design and evidence
4. Is the study design strong enough for the claims?
NEJM strongly favors large randomized controlled trials. Observational studies are published but face higher scrutiny. Post-hoc analyses of trials designed to answer different questions are typically desk rejected. The design must be pre-specified and appropriate for the primary outcome.
5. Is the trial registered before enrollment began?
NEJM requires prospective trial registration in an approved registry (ClinicalTrials.gov, WHO ICTRP) before the first participant is enrolled. Manuscripts describing unregistered trials are returned without review. The registration number must appear in the abstract.
6. Does the registered primary outcome match the manuscript?
Editors check. If the primary outcome in the published paper differs from the registered primary outcome, this raises selective reporting concerns. Any protocol amendments must be documented and justified.
Statistical rigor
7. Will the analysis survive independent statistical review?
NEJM sends papers that advance to revision for independent statistical review by one of five statistical consultants. This review is rigorous and evaluates sample size justification, analytical methods, missing data handling, multiplicity corrections, and subgroup analysis validity. Many authors are not prepared for this level of statistical scrutiny.
Prepare by ensuring: sample size is justified with a power analysis, the primary analysis is pre-specified, sensitivity analyses address missing data, subgroup analyses are identified as pre-specified or exploratory, and confidence intervals are reported alongside p-values.
8. Are the results reported with appropriate precision?
Exact p-values (not just "p<0.05"). Confidence intervals for all primary outcomes. Effect sizes, not just significance. Hazard ratios, odds ratios, or absolute risk differences as appropriate. NEJM has strict statistical reporting standards.
Compliance and ethics
9. Are all ethics approvals documented?
IRB/ethics committee approval with institution name and approval number in the methods. Informed consent described. DSMB (Data Safety Monitoring Board) oversight described if applicable. NEJM will not review without complete ethics documentation.
10. Have all authors declared conflicts and confirmed authorship?
NEJM permits only one corresponding author. Credit for authorship requires substantial contributions to conception, design, data acquisition, analysis, or interpretation. All conflicts of interest must be declared. NEJM has detailed financial disclosure requirements.
11. Is AI use disclosed?
As of 2024, NEJM requires disclosure of AI-assisted technologies used in manuscript preparation. If you used ChatGPT, Claude, or any AI tool, disclose it at submission.
Strategic fit
12. Have you considered a Rapid Review request?
NEJM offers Rapid Review for time-sensitive findings. If your result has immediate public health implications (pandemic data, safety signals, urgent clinical findings), you can request rapid review with a decision typically within 2 weeks and publication expedited.
For non-urgent submissions, consider whether a presubmission inquiry (brief letter describing the work) would help calibrate expectations before investing in the full submission.
The readiness shortcut
NEJM's 90% desk rejection rate means 9 out of 10 submissions are stopped before review. Check your readiness automatically. The Manusights free scan evaluates your manuscript against NEJM's editorial standards in about 60 seconds.
For a paper targeting NEJM, the stakes are the highest in academic medicine. The $29 AI Diagnostic provides verified citations from 500M+ live papers, figure-level feedback, and journal-specific calibration. For the most career-defining submissions, Manusights Expert Review connects you with a reviewer who has published in and reviewed for NEJM.
What gets NEJM papers desk rejected
The Executive Editor reviews every research submission personally. The desk decision is based on:
- Clinical impact too narrow. The finding matters within one specialty but does not change broad clinical practice.
- Study design limitations. An observational study making causal claims. A post-hoc analysis of a different trial. An underpowered study with borderline results.
- The result is confirmatory. Confirming what is already known, even with a larger trial, is less interesting than a finding that changes practice.
- Registration problems. Unregistered trials are returned immediately. Registration after enrollment began is flagged.
- The paper has been substantially published. Prior publication of primary results in any form (including preprints with detailed results) may affect NEJM's consideration.
