British Medical Journal

BMJ (or British Medical Journal) began its mission in 1840 to lead the debate on health, and to engage, inform, and stimulate doctors, researchers and other health professionals in ways to improve outcomes for patients, ultimately aiming to help doctors make better decisions. Every research article published in the BMJ is immediately accessible on bmj.com through open access, to everyone at no charge.

Research Articles:

  • As all articles are made available for free and immediate access on-line, BMJ do not specify word limits for their research articles. However, articles are required to be clear and concise.
  • Manuscripts are to be ordered by the IMRAD (Introduction, Methods, Results and Discussion) structure. They should include all of the information recommended by the relevant researching reporting guideline or statement (for example, CONSORT).
  • An abstract of 250–600 words should be organised under the following headings: Objectives, Design, Setting, Participants, Interventions, Main Outcome Measures, Results, and Conclusions. These should be written in the active voice, but should not include personal pronouns.
  • For correct spelling, refer to Chambers 21st Century Dictionary for general usage and Dorlands for medical terms. Note this is English spelling, not American.
  • Numbers under 10 should be spelt out, except for measurements with a unit (8 mmol/l) or age (6 weeks old), or when in a list with other numbers.
  • Write in the active voice and use the first person where necessary. Try to avoid long sentences that have several embedded clauses.
  • Abbreviation should be kept to minimum.
  • Scientific measurements should be given in SI units, except for blood pressure, which should be expressed in mm Hg.
  • When giving percentages, raw numbers should be provided alongside them. This applies similarly for P values.
  • Hyphens should be kept to a minimum and used only for words with non-, -like, -type, and for adjectival phrases that include a preposition (one-off event, run-in trial).
  • No full stops in initials or abbreviations.
