The field of transplant research has long been recognized for its innovative approaches and international collaborations. This study aims to dissect the landscape of global collaborations within transplant research during a past decade.
Through a comprehensive bibliometric and network analysis of 5 high-impact factor transplantation journals from 2012 to 2021, we evaluated scientific production and collaboration patterns in 9 250 articles. International, national, and single-institution collaboration types were analyzed, using coauthorship as a measure of scientific collaboration.
The data set revealed 40 622 authors from 2 094 institutions across 94 countries, with a marked increase in international collaborations during the past decade. The United States and Western European countries emerged as central nodes in the global network, facilitating the majority of collaborative efforts. Only 2.2% of potential institutional collaborations were explored during the decade. We found a lower chance of citations for single-institution research over time. Low- and middle-income countries were underrepresented in high-impact transplant research.
The findings underscore the necessity of fostering inclusive, equitable research collaborations that bridge the gap between high-income countries and low- and middle-income countries, limiting their contributions to advancing global patient care. Practical recommendations for enhancing global collaboration in transplant research include facilitating academic exchanges, equitable collaboration practices, and increased funding opportunities. This study calls for a strategic shift toward a more inclusive and integrated global research landscape, aiming to advance transplant research and patient care universally. Addressing these disparities could lead to a more integrated global research landscape, benefiting transplant research and patient care universally.
移植研究领域长期以来因其创新方法和国际合作而受到认可。本研究旨在剖析过去十年移植研究中的全球合作格局。
通过对2012年至2021年5种高影响因子移植期刊进行全面的文献计量和网络分析，我们评估了9250篇文章的科研产出和合作模式。使用共同作者情况作为科学合作的衡量标准，分析了国际、国家和单机构合作类型。
数据集显示来自94个国家2094个机构的40622名作者，过去十年国际合作显著增加。美国和西欧国家成为全球网络的中心节点，推动了大部分合作努力。在这十年间，仅探索了2.2%的潜在机构合作。我们发现随着时间推移，单机构研究被引用的可能性较低。低收入和中等收入国家在高影响力移植研究中的代表性不足。
研究结果强调了促进包容性和平等研究合作的必要性，这种合作能够弥合高收入国家与低收入和中等收入国家之间的差距，而目前这种差距限制了它们对推动全球患者护理的贡献。加强移植研究全球合作的实际建议包括促进学术交流、公平合作实践以及增加资金机会。本研究呼吁向更具包容性和综合性的全球研究格局进行战略转变，旨在普遍推进移植研究和患者护理。解决这些差距可能会带来更综合的全球研究格局，普遍惠及移植研究和患者护理。
