Productivity characteristics of the thesis rate of PhD students in biomedical areas of the different doctoral programs in Lima, Peru: A 20-year retrospective study

Objective: The aim of this study was to determine the productivity characteristics related to the thesis rate of biomedical students of the PhD program in Health Sciences in Lima, Peru through a 20-year retrospective study. Materials and Methods: This was a retrospective, comparative, cross-sectional study. The evaluation period consisted of two time periods, 1999-2014 and 2015-2019, to differentiate thesis defense production both before and after the promulgation of the new University Law 30220 in Peru. The student population included graduates from different professional areas (Dentistry, Medicine, etc.). An electronic search for all the data was carried out by using the Universidad Nacional Mayor de San Marcos (UNMSM) SUM (Unique Registration System) software. Results: It was found that the highest prevalence of students who entered in the doctoral programs of the UNMSM Faculty of Medicine was 26.6% in 2013, whereas the highest prevalence of graduates was 24.4% in 2016. Finally, the highest prevalence of graduates who engaged in thesis defense was 41.4% in 2017. There has been a constant increase in thesis production, with the cutoff point being from 2014 onward. The Pearson's chi-square test showed a significant association between the type of PhD program and thesis defense (P = 0.008). Conclusion: The greatest production of thesis defense was carried out from 2014 to 2019. In addition, there was a significant association between thesis defense according to the PhD program and the professional career of the PhD student; however, none of the factors associated with the influence of obtaining a PhD degree in any of the programs evaluated was statistically significant.
