Survey of h-index for neurosurgeons in Saudi Arabia

OBJECTIVES: To calculate the h-index for neurosurgeons in the Kingdom of Saudi Arabia (KSA), and to assess its association with a number of features relating to neurosurgical practice in KSA. METHODS: The h-index for 84 neurosurgeons that worked in KSA during 1990-2013 was evaluated using Google Scholar during the period September to October 2014. The correlation between the h-index and a number of neurosurgeon and neurosurgical center characteristics was determined and examined statistically. RESULTS: The median h-index was 2.5 (range 0-33) and the mean was 5.04. The h-index was significantly higher for neurosurgeons who obtained their certification before 2001 and those working at the King Faisal Specialist Hospital, Riyadh, KSA. The h-index was also higher, but without reaching significance, for non-Saudi neurosurgeons, those with international certification and those working at the university hospitals. Additionally, the h-index was significantly lower for neurosurgeons working in the Ministry of Health hospitals. CONCLUSION: Application of the h-index to KSA neurosurgeons revealed a significant correlation with the duration after certification and with certain centers. Evaluation of the h-index should be included in the consideration for academic positions in KSA. Saudi neurosurgeons should be encouraged to publish in journals with high impact factor.
