The global landscape of willingness to pay for community-based health insurance research: A bibliometric analysis

This study aims to analyze the global research landscape on Willingness to Pay (WTP) for Community-Based Health Insurance (CBHI) from 2002 to 2024. It seeks to identify key trends, influential contributors, regional disparities, and thematic focus areas, offering insights to guide future research and policy development. A bibliometric analysis was conducted using 354 documents sourced from Dimensions, Scopus, and PubMed. The Bibliometrix package in R Studio, along with the Biblioshiny application, was employed to examine publication trends, citation metrics, collaboration networks, and keyword distributions. Bradford's and Lotka's Laws were applied to evaluate journal productivity and author contribution patterns. Data visualizations, including geographical distribution maps and author productivity charts, were used to present findings. The analysis revealed an annual publication growth rate of 10.12%. Ethiopia led in research output (15.8%), while Burkina Faso's publications were most cited. International collaborations were present in 31.64% of studies, indicating increasing global engagement. Key publishing journals included <i>BMC Health Services Research</i> and <i>PLOS ONE</i>. Influential authors such as Sauerborn R and De Allegri M emerged as central figures in the field. The field of WTP for CBHI is expanding and contributing to the discourse on healthcare financing and equity, especially in LMICs. However, research contributions were regionally skewed, with underrepresentation from South America and Oceania, and a notable reliance on a small group of productive authors. To strengthen CBHI's potential for achieving universal health coverage, it is crucial to address regional research disparities, foster interdisciplinary collaboration, and explore emerging areas such as behavioral economics and technology integration.
