PurposeMedical humanities is a field which implies collaborative work across disciplines although the degree to which this actually occurs is unknown. Our purpose was to determine the degree of joint work in medical humanities through analysis of authorship and acknowledgements in the two main medical humanities journals.MethodsObservational survey of authorship. We studied authorship data in all papers published in the two major general medical humanities journals between 2009 and 2018.ResultsTwo-thirds of papers had single authors, of whom a majority declared a (...) single disciplinary affiliation. The titles of 60.8% of papers explicitly suggested collaborative content of which 19.9% had multiple authors from more than one discipline ; of the remainder, almost half had a single, single-disciplinary author. One-third of papers referenced one or more people in the acknowledgements. Among papers whose titles suggested humanities or medical content only, authorship lists of 10.2% and 17.9% respectively demonstrated collaborative scholarship.ConclusionsDespite considerable involvement from both humanities and medical practitioners, there is still substantial scope for enhanced emphasis on collaborative seminars and exchanges in the medical humanities and editorial policies to promote transparency of the nature of collaborative work among disciplines. Journal editors and editorial boards should reflect on the opportunity to promote enhanced visibility of joint work in scholarship in the medical humanities through reflection and review of current editorial policies.
