Objective: In Peru, the past three decades have witnessed impressive growth in biomedical research catalyzed from a single research university and its investigators who secured international partnerships and funding. We conducted a bibliometric analysis of publications by Peruvian authors to understand the roots of this growth and the spread of research networks within the country.
Methods: For 1997-2016, publications from Web of Science with at least one author affiliated with a Peruvian institution were examined by year, author affiliations, funding agencies, co-authorship linkages, and research topics.
Results: From 1997-2016, the annual number of publications from Peru increased 9-fold from 75 to 672 totaling 6032. Of these, 56% of the articles had co-authors from the US, 13% from the UK, 12% from Brazil, and 10% from Spain. Universidad Peruana Cayetano Heredia (UPCH) was clearly the lead research institution noted on one-third of publications. Of the 20 most published authors, 15 were Peruvians, 14 trained at some point at UPCH, and 13 received advanced training abroad. Plotting co-authorships documented the growth of institutional collaborations, the robust links between investigators and some lineages of mentorship.
Conclusions: This analysis suggests that international training of Peruvian physician-scientists who built and sustained longstanding international partnerships with funding accelerated quality research on diseases of local importance. The role of a single research university, UPCH, was critical to advance a culture of biomedical research. Increased funding from the Peruvian Government and its Council for Science, Technology and Innovation will be needed to sustain this growth in the future. Middle-income countries might consider the Peruvian experience where long-term research and training partnerships yielded impressive advances to address key health priorities of the country.
