Objective To visualize the international research hotspots and frontiers of primary healthcare workers burnout during the COVID-19 pandemic based on CiteSpace.

Methods Publications from January 1 2020 to November 1 2022 were retrieved from the web of science core collection database. Annual published articles， keyword co-occurrence， cluster analysis and emergent word evolution were analyzed. Using CiteSpace 5.8.R3 and Excel 2017， visualized knowledge graphs and the data tables were generated.

Results A total of 411 articles were included with a still upward trend. The top 4 institutions with the largest number of papers were Harvard Medical Scchool （14 studies）， University of Melbourne （11 studies）， Stanford University （9 studies）， and Monash University （9 studies）. High-frequency words of hot areas covered job satisfaction， occupational burnout， and mental health. Meanwhile the words environment （0.38） and social support （0.13） had high betweenness centrality. A total of 9 clusters were formed. Risk factors and supporting strategies were put in place most focused frontiers.

Conclusion The number of papers in the field of primary healthcare workers burnout is on the rise， the international research hotspots are expanding and the predictors of burnout are prominent. From an international perspective， the study provides further reference for Chinese primary healthcare staff job burnout research.
