Abstract

Background

While various studies have investigated trends in characteristics of authors in other medical literature, no study has examined these characteristics in the field of arthroplasty.

Methods

A database was created of all articles published in The Journal of Arthroplasty in 1986, 1990, 1995, 2000, 2005, 2010, and 2015. Degree(s) of authors, number of authors, number of references, and region of institution were recorded.

Results

A total of 1343 original articles were assessed over the study period. There was a significant increase in the number of authors per publication from 3.45 in 1986 to 4.98 in 2015 (P < .001) and number of references per article from 17.36 to 29.76 (P < .001). There was a significant increase in proportion of first authors with a bachelor's degree (P = .001), MD/PhD (P < .001), and MD/MBA (P = .016), with a significant decrease in first authors with an MD degree only (P < .001). There was a significant increase in number of last authors with an MD/PhD (P = .001) and MD/MBA (P = .003). There has been a significant growth in papers from outside North America (P = .007), with a decrease in articles from the UK/Ireland (P = .003) and an increase in contributions from the Far East (P < .001).

Conclusion

Trends of authorship characteristics in the arthroplasty literature largely mirror those seen in other medical literature including increased number of authors per article over time, changes in author qualifications, and increased contributions from international author groups.
