Research Productivity among Filipino Neurologists Associated with Socioeconomic, Healthcare, and Disease Burden Factors: A Bibliometric Analysis.

Philippine research productivity in neurology has not been fully characterized. We investigated the research output of adult and child neurologists in the Philippines and correlated this to the Philippine socioeconomic and healthcare indices among different regions. We used electronic databases to retrieve studies published by Filipino neurologists using the 2022 Philippine Neurological Association website as reference. We included all studies published until December 2021. Official government region-specific socioeconomic indices were used. Correlational analysis was completed on bibliometric indices and collected data. We retrieved 746 articles from 274 of 526 Filipino neurologists which were published in 245 publications over 45 years with 12,409 citations. The National Capital Region (NCR) had the most publications ( n = 662, 88.7%) and citations ( n = 10,377, 83.6%). Research productivity was positively correlated with population, gross domestic product (GDP), health expenditure, number of healthcare establishments, neurologists, and research personnel. The Philippine research landscape is dominated by articles of neurologists belonging to institutions in the NCR, which has the greatest number of neurologists, training institutions, and highest GDP. There is a need to address the disparity seen in other regions to bridge gaps in healthcare, health human resources, and health information through research.
