The landscape of hematology research in Brazil: an analysis of data from citation databases.

Introduction: Scientometrics is the field concerned with measuring and analyzing academic literature, using specific metrics and data from bibliometric databases. Hematology is a broad area of science and medicine, from which several landmark scientific discoveries have emerged.

Objective: The aim of this report is to provide a snapshot of the landscape of hematology research in Brazil, based on a comprehensive analysis of published studies in hematology whose authors were affiliated to Brazilian institutions from 1980 to 2020.

Method: Articles, reviews and letters to the editor with at least one author affiliated to a Brazilian institution were retrieved from Incytes/Web of Science or Scopus databases. Importantly, only papers classified in the subject area "Hematology" by the embedded algorithms of each database were included.

Results: Considering all published papers, Brazil is in the 22nd position, contributing with around 1.1% of papers in this period. A clear and sustained increase in publication output can be observed from the early 1990's to the present moment. Publicly-funded higher education institutions were the main contributors to the development and consolidation of the hematology scientific community, which has grown in diversity, with an increasing number of contributions from private institutions. In regard to funding, public agencies have been and remain by large as the most important funder of research in hematology in Brazil.

Conclusion: We suggest that continuous monitoring of the temporal trends of some of the data compiled in our report could potentially contribute to a clearer picture of the development of hematology research in Brazil.
