Everyone knows that ghostwriting and guest authorship are bad, but it is rare for those guilty of the practice to face meaningful consequences. I am particularly impressed with Stern and Lemmens's insightful dissection of the reasons why this is so.\n\nSo, would legal action be a useful way of dealing with the problem? I doubt that it could be an answer by itself. Legal action is expensive and cumbersome, and unlikely in practice to be used in any but the most extreme cases. Nonetheless, the deterrent effect may be useful, even if only a very small number of guest authors are brought to justice this way. So I think it is certainly an interesting option, and I look forward to seeing some cases brought as Stern and Lemmens describe.\n\nBut I do think that any meaningful attempt to solve the problem must involve journal editors. They are in a unique role as gatekeepers, and they must do more. Guest authors and ghostwriters will persist while journals fail to ask searching questions about how articles were developed as a matter of routine.\n\nI and some colleagues published a paper in this journal in 2009 with a checklist designed as a practical tool to help journal editors avoid ghostwritten articles with minimal resources [1], but disappointingly, I'm not aware of any journal that is currently using it.\n\nThere are, however, some parts of Stern and Lemmens's article with which I have to take issue. Professional medical writers are mentioned only in the context of ghostwriting. In fact, professional medical writers can, when transparently acknowledged, provide a valuable and ethical service. It is quite wrong to assume that professional medical writers are the same thing as ghostwriters. The European Medical Writers Association has published guidelines on how medical writers can contribute to papers responsibly [2].\n\nIt is also wrong to assume that guest authorship is only a problem with industry-sponsored publications. Guest authorship is also common in academia. I am not aware of any data comparing the frequency of ghost authorship in industry and non-industry publications, but given that a 2002 publication found that 39% of Cochrane reviews (which are independent of industry) had guest authors, it is clearly not a problem confined to industry.\n\nIt is important to ensure that standards are maintained in all biomedical publications, rather than focusing on one specific subgroup. This is particularly true in the light of recent evidence which suggests that fraud is more common in independent papers than in those sponsored by the pharmaceutical industry [4].\n\nReferences:\n\n1.

It is fairly common to add extra guest or courtesy authors for various reasons e.g. they are well known and might increase the appeal of the paper to editors and reviewers, they are well-respected colleagues or indeed they are people who have worked hard on the project but don't fulfil the much criticised ICMJE criteria.
