Anesthesia research is essential for advancing clinical practice and patient care. The purpose of this study was to analyze research productivity in Canadian anesthesiology departments from 2014 to 2023, focusing on trends in publication volume, methodology, and the impact of the COVID-19 pandemic. A bibliometric analysis was conducted following a pre-registered protocol to identify articles in the PubMed database, which were published between 2014 and 2023 (inclusive) with corresponding authors from Canadian anesthesiology departments. Data extracted for each article included the year of publication, journal, and study design. Descriptive statistics and Pearson correlation coefficient were used to compare trends, while annual publication rates were assessed with linear regression. An interaction term captured differences between pre-pandemic (2014-2020) and post-pandemic (2021-2023) periods. A total of 3,490 articles met the inclusion criteria. From 2014 to 2020 (pre-pandemic period), publication volume increased significantly by 28.7 studies/year (95% CI: 19.2-38.2, p < 0.001). In contrast, 2021-2023 (post-pandemic period) showed a non-significant decline of 13.0 studies/year (95% CI: -48.6-22.6, p = 0.405). Pre-pandemic trends showed significant growth in reviews, case-control/cohort studies, and surveys, while publication rates declined across most categories after 2020. Our findings illustrate an increase in research productivity among Canadian anesthesiology departments from 2014 to 2020, followed by a plateau in publication volume after the onset of the COVID-19 pandemic. This stagnation highlights a critical area for future exploration, including examining how pandemic-related factors, such as shifts in clinical priorities, resource allocation, and adoption of telemedicine in pre-operative clinics, have influenced research productivity. As the field of anesthesiology adapts to post-pandemic realities, ongoing bibliometric studies will be essential to monitor these trends and guide the trajectory of Canadian anesthesia research amid emerging clinical challenges and evolving academic priorities.
麻醉学研究对于推动临床实践和患者护理至关重要。本研究的目的是分析2014年至2023年加拿大麻醉学系的研究生产力,重点关注发表量、方法学的趋势以及新冠疫情的影响。按照预先注册的方案进行文献计量分析,以识别PubMed数据库中2014年至2023年(含)发表的、通讯作者来自加拿大麻醉学系的文章。为每篇文章提取的数据包括发表年份、期刊和研究设计。使用描述性统计和皮尔逊相关系数来比较趋势,同时用线性回归评估年度发表率。一个交互项捕捉了疫情前(2014 - 2020年)和疫情后(2021 - 2023年)期间的差异。共有3490篇文章符合纳入标准。从2014年到2020年(疫情前时期),发表量显著增加,每年增加28.7项研究(95%置信区间:19.2 - 38.2,p < 0.001)。相比之下,2021 - 2023年(疫情后时期)显示每年非显著下降13.0项研究(95%置信区间:-48.6 - 22.6,p = 0.405)。疫情前的趋势显示综述、病例对照/队列研究和调查有显著增长,而2020年后大多数类别发表率下降。我们的研究结果表明,2014年至2020年加拿大麻醉学系的研究生产力有所提高,随后在新冠疫情爆发后发表量趋于平稳。这种停滞凸显了未来探索的一个关键领域,包括研究与疫情相关的因素,如临床重点的转移、资源分配以及术前诊所中远程医疗的采用,如何影响了研究生产力。随着麻醉学领域适应疫情后的现实,持续的文献计量研究对于监测这些趋势以及在新出现的临床挑战和不断演变的学术重点中指导加拿大麻醉学研究的轨迹至关重要。
