Two decades of research on tuberculosis in Brazil: state of the art of scientific publications

Abstract

The trends of scientific articles about tuberculosis in Brazil published between 1986 and 2006 were analyzed. This analysis included Capes database-indexed dissertations and theses and papers indexed in Medline and SciELO. Papers containing the word "tuberculosis" and authors affiliated to Brazilian institutions were included in the assessment. The analysis showed initially case report and review publications, and later it shifted to original articles on science, technology and innovation. These changes may reflect the strengthening of scientific research activities and new attitudes regarding tuberculosis research objectives in academic institutions in recent years. Although many theses used qualitative methodology, few qualitative publications were found, possibly because of the quantitative orientation of many journals. Qualitative versus quantitative research and education versus research-oriented publications are discussed, together with public policies and strategies to include research as a tool to control diseases. The use of the same methodology is suggested to assess the trends in research on other neglected diseases.
