BACKGROUND/OBJECTIVES: After years of growth in many pancreas transplant programs, UNOS has reported declining transplant numbers in the USA. This precipitating trend urges for an evaluation of the transplant numbers and scientific productivity in the Eurotransplant region and the UK.
We performed a trend analysis of pancreas transplantation rates, between 1997 and 2016, adjusting for changes in population size, and an analysis of scientific publications in this field. We used information from the UNOS, Eurotransplant, and UK transplant registry and bibliometric information from the Web of Science database.
Between 2004 and 2016 there was an average annual decline in pancreas transplantation rates per million inhabitants of 3.3% in the USA and 2.5% in the Eurotransplant region. In the UK, transplant numbers showed an average annual decline of 1.0% from 2009 to 2016. Publications in Q1 journals showed an annual change of -2.1% and +20.1%, before 2004, and a change of -3.8% and -5.5%, between 2004 and 2016, for USA and Eurotransplant publications, respectively.
Adjusting pancreas transplantation rates for changes in population size showed a clear decline in transplant numbers in both the USA and Eurotransplant region, with first signs of decline in the UK. Following this trend, the number of scientific publications in this field have declined worldwide.
背景/目的:在许多胰腺移植项目多年增长之后,UNOS 报告称美国的移植数量有所下降。这种急剧下降的趋势促使人们对欧洲移植区域和英国的移植数量和科学生产力进行评估。
我们对胰腺移植率进行了趋势分析,时间跨度为 1997 年至 2016 年,同时调整了人口规模的变化,并对该领域的科学出版物进行了分析。我们使用了来自 UNOS、欧洲移植组织和英国移植登记处的信息,以及来自 Web of Science 数据库的文献计量信息。
在 2004 年至 2016 年期间,美国每百万居民的胰腺移植率平均每年下降 3.3%,而欧洲移植区域的这一数字则为 2.5%。在英国,从 2009 年至 2016 年,移植数量平均每年下降 1.0%。Q1 期刊的出版物在 2004 年之前的年变化率为-2.1%和+20.1%,而在 2004 年至 2016 年期间,美国和欧洲移植出版物的变化率分别为-3.8%和-5.5%。
根据人口规模的变化调整胰腺移植率后,美国和欧洲移植区域的移植数量均出现明显下降,英国也出现了下降的最初迹象。随着这一趋势的发展,该领域的科学出版物数量在全球范围内有所下降。
