To the Editor:

It is always comforting to find reviews in your journal from many health professionals from Spain and further afield; well written and researched articles, focused on current, interesting subjects. However, the recent "Brief Reports" by San Román et al1 has generated some varied feelings: pleasure at reading an article focused on a field that has been and currently is a motive for study by our team, and disappointment upon analysing the bibliography that was included.

Of the 14 references listed, one of them is repeated,2 two have "minor" errors (incomplete information),3,4 and 3 have serious errors regarding the attributed authors.5-7 With regard to the sections that affect us, our original text focuses on inadequate admissions, and not inadequate stay as referenced. The article possibly was referring to another piece written by our team, in which inadequate stays were assessed.8

As a result of these findings, it must be remembered that a bibliography is the scientific support for the study, and a study that is well supported bibliographically will show that the work has been carried out with great attention to detail. In addition to this, all the information from the bibliographic references have to be checked against their original sources, verifying the names of the authors, the title of the document and the name of the publication in which it appears, as well as the year of publication, the volume and the page numbers.9,10

Finally, we do understand that detection of these errors is also the role and responsibility of the journal editors (pairs of editors), a point which is key for the constant improvement to the already high quality Revista Española de Cardiología journal.
