Medical errors represent a critical challenge to global healthcare systems, ranking among the leading causes of preventable morbidity and mortality. The aim of this study was to explore the evolution, characteristics, and correlation of research on medical errors and global health and research indicators. A mixed-methods scientometrics study was conducted to analyse publications from 1865 to 2024 on medical errors from five databases. Correlational analyses were performed, focusing on publication trends, geographic and economic disparities, journal metrics, and thematic evolution. Multiple regression assessed relationships between bibliometric metrics and global indicators. Five thousand seven hundred thirty-two publications related to medical errors were analysed. An annual growth rate of 1.49% was documented, with high-income countries contributing 83.32% of publications. The Americas accounted for the highest regional output, while Africa and Southeast Asia showed marginal contributions. Most studies were published in high-impact journals (46% in Q1), but only 22.98% were open access. Thematic analysis revealed a transition from error reporting to mitigation strategies. Correlations showed strong associations between intellectual property fees and publication volume (r²=0.75; p<0.001), while official development assistance negatively correlated with publication output (r²=-0.33; p<0.01). Disability-adjusted life years showed weak correlations with publication volume (r²=0.32; p<0.01) and journal impact (r²=0.14; p<0.001). This study highlights significant inequities in global research on medical errors, with high-income countries dominating production. While thematic shifts suggest advancements in the field, the lack of representation from low- and middle-income countries and limited access to open-access publications pose barriers to global applicability.

INTRODUCTION: The Centers for Medicare and Medicaid Services established the Open Payments Database (OPD), designed to track all general and research payments made by corporations to physicians, to promote greater financial transparency. While previous studies have analyzed general payments using the OPD database, there has been no investigation into public vs. private research payments related to neurosurgery from 2015 to 2021. METHODS: A cross-sectional analysis of the OPD and NIH RePORTER was conducted from 2015 to 2021 for research payments to neurosurgeons and payments tagged with the keyword “neurosurgery.” The data was cleaned; the primary investigators were subclassified according to the neurosurgical subspecialty of their research, and descriptive statistics were computed for payments at the provider and manufacturer levels. RESULTS: The total public and private funding for neurosurgery from 2015 to 2021 was $1,008,953,855.00 and $171,326,087.05, respectively. Public funding has a compound annual growth rate (CAGR) of 5.37%, and private funding has a CAGR of 7.46%. Neurovascular was the highest privately funded subspecialty at 26.2%, and neuro-oncology was the highest publicly funded subspecialty at 32.1%. CONCLUSIONS: We found significant growth in neurosurgery funding in the private and public sectors from 2015 to 2021. Private funding emphasizes neurovascular research the most and neurosurgical pediatric research the least, whereas public funding focuses on neuro-oncology research, with the least funding for neurosurgical spine research. These findings offer valuable insights into funding trends and characteristics in neurological research, highlighting the differences between funding sources and promoting equitable distribution to advance the field.
