The structure of qualitative studies: a bibliometric pattern of biomedical literature.

The lack of knowledge in the biomedical literature regarding the validity of qualitative studies might be related to the lower number of qualitative studies that have been published. The criticisms range from a lack of theoretical depth to the superficial discussions of empirical findings. The aim of this study was to explore the bibliometric entities and the trends in the structure of qualitative research in the biomedical literature. A bibliometric analysis and mapping of the biomedical literature were used. The number of studies selected was 1,725. The heath themes with the most publications included Health Management (12%) and Women's Health (9.8%), while the authors of the studies had academic affiliation in 76 different countries. The sample sizes were between 11 and 20 participants (27.13%) and the Grounded Theory framework (9.04%) stood out. The improved structuring of a qualitative research extends the effective communication between health providers and researchers, and support in the management of clinical situations.
