预立医疗照护计划研究热点、演变路径及发展趋势的可视化分析

Visual analysis of research hotspots,evolution paths and development trends of advance care planning

目的了解预立医疗照护计划(ACP)科研合作网络特征、研究热点、演变路径和发展趋势等,为后续相关研究提供借鉴。方法以“advance care planning”为主题词,将基于Web of Science核心合集数据库的检索结果分别导入VOS viewer和CiteSpace软件进行可视化分析,检索时间为建库至2021年2月3日。结果共2456篇文献符合入选标准,1993—2009年的年发文量均小于50篇,2010年至今发文量呈迅速上升趋势,被引频次分布趋势与发文量分布趋势基本相同,且以欧美作者和机构居多。香港中文大学的Chan Helen Yue-lai发文量居我国第1位和世界第19位,我国学者在该领域的研究尚处于起步阶段。研究热点有ACP替代决策技能培训等,研究前沿与演变路径有ACP、严重精神疾病、替代决策、生命计划、晚期肾脏疾病、医生医嘱、ACP模型、晚期痴呆、慢性心力衰竭等。结论自2010年开始,该领域发文量和被引频次均呈迅速上升趋势,学科发展较好的国家有美国、比利时、加拿大等,我国学者在该领域具有广泛的发展空间,可借鉴国外ACP文献报道的先进研究经验加深和加快我国ACP领域的临床实践研究。

Objective To understand the characteristics of scientific research cooperation network,research hotspots,evolution paths and development trends of advance care planning(ACP),so as to provide reference for follow-up related research.Methods With the theme of"advance care planning",the retrieval results based on Web of Science core collection database were respectively imported into VOS viewer and CiteSpace for visual analysis,and the retrieval time was from database construction to February 3,2021.Results A total of 2456 articles meet the selection criteria.The annual publications were all less than 50 from 1993 to 2009,which showed a rapid upward trend from 2010 to now.The distribution trend of citation frequency was basically the same as that of publications.Most of the authors and institutions are European and American.Chan Helen Yue-lai of the Chinese University of Hong Kong ranked first in China and 19th in the world in terms of publicationsand Chinese scholars'research in this field is still in its infancy.Research hotspots included ACP alternative decision-making skills training,and the research frontiers and evolutionary paths included ACP,severe mental illness,alternative decision-making,life planning,end-stage renal disease,doctor's orders,ACP model,advanced dementia,chronic heart failure,etc.Conclusions Since 2010,the number of articles published in this field and the frequency of citations have shown a rapid upward trend.The United States,Belgium,Canada and other countries have developed well in this field and Scholars of China have a wide space for development in this field.The advanced research experience reported in the foreign ACP literature can be used for reference to deepen and speed up the clinical practice research in the field of ACP in China.
