Collaborations are an essential element of scientific activity and particularly important in fields such as pediatric anesthesiology, where the evidence base in general is relatively limited. A recent scientometric analysis revealed a geographic diversification of publication activity in pediatric anesthesiology within the last two decades, accompanied by a surge in international collaborations.
Given the hypothesis of a similar growth in the activity and dynamics of publications in pediatric anesthesiology, the objective of this scientometric study was to analyze the publication activity and collaboration habits in research in pediatric anesthesiology from Germany, Austria and Switzerland (D-A-CH).
This secondary analysis identified all publications on pediatric anesthesiology with an affiliation from the D‑A-CH countries between 2001 and 2020 from PubMed and Web of Science. The query parameters included the timeframe 2001-2020, authors' affiliations tied to anesthesiology departments (using various forms of the term "anesthesia"), and the mention of pediatric interest in titles or abstracts. The data underwent standardization to account for linguistic variations. The publications were assigned to a state, city and institution based on the correspondence address, to a year based on the publication date and to a source based on the journal. The primary endpoint was publication activity and dynamics, represented by the number of publications and the respective growth rates (calculated as the linear regression slope). Secondary endpoints included the share of collaborations within and outside the D‑A-CH region (at the country and institutional level), the distribution of publication activity and the most prominent sources of publications.
Between 2001 and 2020 a total of 3406 publications on pediatric anesthesiology involving authors from the D‑A-CH countries were identified. Of these 2807 (82.4%) had a correspondence address in D‑A-CH. The average annual growth rate of publications with a correspondence address was + 2.9% for the D‑A-CH countries and + 7.7% for publications with collaborations. The number of publications in which an institution from D‑A-CH was named as a coauthor from a correspondence address outside D‑A-CH also increased by an average of 7.4% per year during the study period. The majority of collaborations occurred between institutions within the D‑A-CH region, although Swiss institutions exhibited a much higher proportion of collaborations outside the region. Of all publications with a correspondence address 90% originated from 46 cities. The most prominent source was Die Anästhesiologie for publications from Germany, and Pediatric Anesthesia for publications from Austria and Switzerland.
The number of publications in pediatric anesthesiology from the D‑A-CH countries has increased over the past two decades, accompanied by a surge in collaborations. It is hoped that increased collaboration will contribute to a higher level of evidence in pediatric anesthesiology care.
合作是科学活动的重要组成部分，在儿科麻醉学等领域尤为重要，因为该领域的证据基础总体上相对有限。最近的一项科学计量分析显示，在过去二十年中，儿科麻醉学的发表活动呈现出地域多元化，同时国际合作也激增。
鉴于假设儿科麻醉学的发表活动和动态有类似的增长，本科学计量研究的目的是分析德国、奥地利和瑞士（D-A-CH）儿科麻醉学研究中的发表活动和合作习惯。
这项二次分析从PubMed和Web of Science中识别出2001年至2020年间所有来自D-A-CH国家且与儿科麻醉学相关的出版物。查询参数包括时间范围2001 - 2020年、与麻醉科相关的作者单位（使用“麻醉”一词的各种形式），以及标题或摘要中提及的儿科相关内容。对数据进行标准化以考虑语言差异。根据通讯地址将出版物分配到一个州、城市和机构，根据出版日期分配到年份，根据期刊分配到来源。主要终点是发表活动和动态，以出版物数量和各自的增长率（计算为线性回归斜率）表示。次要终点包括D-A-CH地区内部和外部（国家和机构层面）的合作份额、发表活动的分布以及最主要的出版物来源。
2001年至2020年间，共识别出3406篇涉及D-A-CH国家作者的儿科麻醉学出版物。其中2807篇（82.4%）的通讯地址在D-A-CH。通讯地址在D-A-CH国家的出版物的年均增长率为+2.9%，有合作的出版物年均增长率为+7.7%。在研究期间，通讯地址在D-A-CH以外但将D-A-CH的机构列为共同作者的出版物数量也平均每年增长7.4%。大多数合作发生在D-A-CH地区内的机构之间，不过瑞士机构与地区外的合作比例要高得多。所有通讯地址在D-A-CH的出版物中，90%来自46个城市。德国出版物最主要的来源是《麻醉学》，奥地利和瑞士出版物最主要的来源是《儿科麻醉》。
在过去二十年中，D-A-CH国家的儿科麻醉学出版物数量有所增加，同时合作也激增。希望合作的增加将有助于提高儿科麻醉护理的证据水平。
