The activity of scientists promotes medical research in health services. However, on many occasions, these professionals do not know how to transfer their research results to the market. Therefore, it is worth providing data on aspects such as training in entrepreneurship and scientific mobility to foster knowledge transfer. This paper discusses data on the Spanish case in Health Sciences to devise effective policies in these areas. To this end, following the methodology of the Global Entrepreneurship Monitor report and the existing scientific literature, 291 researchers involved in scientific mobility in Spain have been interviewed. Of these, 90 belonged to health areas: Spanish scientists abroad (37), Scientists returned to Spain (16), and Young researchers in Spain (37). The results show that the mobile scientists in this area have more entrepreneurial and intrapreneurial intentions, have acquired more entrepreneurial skills, and have received more training in these subjects. Furthermore, there are few permanent positions for all these groups whose mobility decisions fundamentally depend on job opportunities, so the health authorities can intensify these measures to promote knowledge transfer.
