description	Use when judging whether a clinical study clears JAMA's general-medical-importance bar before investing in a full submission. Assesses fit and article-type match; it does NOT design the study or write the paper.

Scope & Importance Fit (jama-scope-fit)

When to trigger

• Before committing weeks to formatting a manuscript for JAMA
• The finding feels solid but you suspect it is too narrow / subspecialty
• Choosing between JAMA, a JAMA Network specialty journal, and a field journal
• An editor or mentor asked "is this really a general-medicine paper?"

The general-medical-importance test

JAMA serves a broad clinician readership across all of medicine. Ask, in order:

1. Does it change what a practicing clinician thinks or does? A result that only matters to a single subspecialty lab rarely fits; a result that informs everyday diagnosis, treatment, or prevention does.
2. Is the question clinically important, not just statistically novel? Mechanistic novelty alone is off-fit; patient-relevant outcomes (mortality, function, major morbidity, validated patient-reported outcomes) are on-fit.
3. Is the evidence near the top of the design hierarchy for the question? RCTs, large well-controlled cohorts, rigorous diagnostic-accuracy studies, and systematic reviews/meta-analyses are the core. Underpowered pilots and uncontrolled case series are off-fit.
4. Is it timely and generalizable? Single-center convenience samples that do not generalize weaken fit.

If you cannot answer (1) and (2) affirmatively, JAMA is probably the wrong home — say so plainly.

Article-type match (verify current types on the journal site)

Your study	Likely JAMA article type
Randomized clinical trial	Original Investigation (with CONSORT)
Prospective/retrospective cohort, case-control	Original Investigation (with STROBE)
Diagnostic-accuracy study	Original Investigation (with STARD)
Systematic review ± meta-analysis	Review / Original Investigation (PRISMA)
Health-policy analysis with clinical bearing	Special Communication / Viewpoint
Short, focused dataset	Research Letter
Synthesis without systematic methods	Off-fit as Original Investigation

Match the article type to JAMA's current categories and word/format limits — verify on the official Instructions for Authors page (do not assume fixed numbers).

What the JAMA desk editor screens before review

JAMA — the Journal of the American Medical Association, the AMA / JAMA Network flagship for a broad clinician readership — desk-rejects most submissions before external review. Triage turns on whether the finding plausibly changes clinical practice or policy, not whether it is correct. Common pre-review desk rejects: a single-center pilot pitched as practice-changing; a surrogate endpoint with no patient-relevant outcome; a retrospectively registered trial (registration must precede enrollment); a mechanism/biomarker paper that changes no decision; an underpowered "negative" trial framed as proof of no effect (absence of evidence is not evidence of absence).

Worked example: routing a vignette (illustrative)

Vignette (illustrative): a multicenter randomized clinical trial, N = 4,200 adults with community-acquired sepsis across 30 sites, restrictive vs liberal IV-fluid strategy; pre-specified primary outcome 90-day mortality, 18.1% vs 21.4%, absolute risk difference -3.3 percentage points (95% CI, -5.9 to -0.7).

• Changes practice (everyday cross-specialty decision), patient-relevant outcome (90-day mortality, CI excludes null), top-of-hierarchy and generalizable (powered, 30-site RCT): all yes.

Verdict: strong fit for a JAMA Original Investigation (CONSORT). Contrast: the same team reporting only a 48-hour serum-cytokine surrogate in 60 patients at one ICU flips to off-fit — route to a specialty journal.

Reviewer / editor pushback and the JAMA fix

• "Clinical bottom line not actionable for practice." Fix: restate importance as a concrete change to diagnosis, treatment, or prevention; if none exists, the venue is wrong.
• "Audience too narrow for JAMA." Fix: evidence broad relevance, or move to the matching JAMA Network specialty title as plan B.

Calibration anchors (hedge where uncertain): the general-medical-importance bar, the evidence hierarchy, and the clinical-decision-impact standard are durable; article-type word/exhibit caps are volatile — confirm against current author guidelines.

Checklist

• The clinical question matters to a broad clinician audience, not one niche
• Primary outcome is patient-relevant, not a surrogate of unclear value
• Study design is high on the evidence hierarchy for this question
• Sample/setting support generalizable conclusions
• A correct JAMA article type exists for this work
• If narrow, a JAMA Network specialty journal or field journal is considered as plan B
• Importance can be stated in one sentence a non-specialist clinician understands

Anti-patterns

• Pitching a single-center, hypothesis-generating pilot as a definitive Original Investigation
• Leading with mechanistic/molecular novelty rather than clinical consequence
• Surrogate-only endpoints presented as practice-changing
• Assuming high statistical significance equals general medical importance
• Ignoring that a better-fit JAMA Network specialty journal exists
