3. Editorial policies


3.1. Revision and publication process


Reception of manuscripts: The corresponding author is notified by e-mail, within 48 hours about the manuscript reception.


Peer review: All submitted manuscripts are treated confidentially by all participants in the review process.



  • Pre-evaluate: All manuscripts are pre-evaluated by an Editorial Committee, which may reject a manuscript according to the next criteria: presentation, style and format required by the journal, figure and tables quality, topic of the study out of the scope of the journal, size data, grammatical aspects and general organization. Manuscripts that do not qualify in the pre-evaluation will be returned to their authors without external revision.
  • Evaluation: Only those manuscripts that seem most likely to meet the journal editorial criteria are sent for formal review. Our peer review process establishes that authors and referees remain anonymous to each other. When an author is directly related to the journal in any way, is automatically excluded from the review process of that manuscript.



Acceptance: It is decided by the Editor based on the recommendation of two or more independent referees and the Associate Editor. A manuscript acceptance requires at least the recommendation for approval of two referees. The editor with the assistance of associate editor can decide changes in the manuscript format (from full-paper to Research Note or viceversa). The corresponding author will be formally communicated the acceptance or rejection of the manuscript.


Editing: In the manuscripts accepted the corresponding author will  revise and approve the final version, however all authors are responsible for the content in their work, including changes made during the editing and production.


Publication: Accepted manuscripts are published by strict chronologically order according to acceptance dates. Unauthorized pre-publication of the manuscript may be result in rescinding the acceptance, so in the rejection for its publication.


3.2 Condition of publication


Publishing charges: Once the manuscript has been accepted and prepared for printing, authors are required to pay US $20.00 or its equivalent in Chilean peso per printed page. 

If the figures are not presented with editorial marks, will be charged an additional amount of US$10.00 for the publication of the figures that are edited by the RBMO.

Publication of book comments and obituaries are free of charges.


Publishing charges may change and will be notified on our website,
