Impact of Post-Master PhD Degree on Publication Productivity in Neurosurgery

Abstract

AIM: To evaluate the impact of the post-master PhD degree on publication productivity in neurosurgery. MATERIAL and METHODS: An online national electronic survey was designed based on the recent literature and factors related to publication productivity. The survey was conducted to simply evaluate main bibliometrics of the participants consisting of neurosurgeons in different stages of their career. The survey was distributed via email to all Turkish Neurosurgical Society members. RESULTS: A total of 220 neurosurgeons participated and answered the survey. Neurosurgeons that had published their Master's dissertation were found to have significantly higher number of published articles, citations and Hirsch (h)-index during their career (p<0.001). Neurosurgeons with a PhD degree who have been involved in such program were found to have significantly higher number of published articles and h-index (p<0.01). A majority of neurosurgeons who were involved in a PhD program were found to work in university hospitals (41.5%) and research and training hospitals (26.8%). Clinical anatomy, neuroscience, and molecular/ genetic biology were the most common PhD programs. CONCLUSION: Standardization in measurability of scientific productivity is mandatory to maintain stability and move further in academic activity. PhD programs have a significant contribution to academic performance and scientific productivity. Surgical residents and young neurosurgeons should be encouraged to be involved in such PhD training programs to promote success in both neurosurgery and scientific arenas.
