In recent years, significant growth has been seen in the subspecialty critical care medicine. However, the national productivity to the subspecialty critical care medicine remains unknown. We therefore intended to reveal the national contribution in the subspecialty critical care medicine journals.
Articles published in 20 highly cited journals in subspecialty critical care medicine from 2006 to 2010 were retrieved from Web of Science and PubMed. The number of total articles and randomized, controlled trials, the per capita numbers, total impact factors (IFs), and citations were tabulated to assess the contribution of different countries.
A total number of 17,667 articles were published in the 20 journals from 2006 to 2010 worldwide. North America, West Europe, and East Asia were the most productive regions. High-income countries published 89.68% of the total articles. The United States published the most number of articles in 2006 to 2010 (6659/17,667, or 37.69%), followed by United Kingdom, Germany, France, and Australia. Besides, the United States also had the most number of randomized, controlled trials (260), the highest total impact factors (27,206.55), and the highest total citations (84,170). When normalized to population size, Australia had the highest number of articles per million population, followed by Netherlands, Switzerland, Austria, and Belgium.
The United States is the most productive country in the subspecialty critical care medicine. When normalized to population size, Australia and some European countries might be more productive.
近年来，重症监护医学亚专业取得了显著发展。然而，该亚专业的全国生产力仍不清楚。因此，我们旨在揭示该亚专业在重症监护医学期刊中的全国贡献。
从 Web of Science 和 PubMed 中检索了 2006 年至 2010 年在 20 种高引用重症监护医学亚专业期刊上发表的文章。对总文章数和随机对照试验、人均文章数、总影响因子（IF）和引用次数进行了列表分析，以评估不同国家的贡献。
全球 20 种期刊在 2006 年至 2010 年共发表了 17667 篇文章。北美、西欧和东亚是生产力最高的地区。高收入国家发表了总数的 89.68%。美国在 2006 年至 2010 年发表的文章数量最多（6659/17667，或 37.69%），其次是英国、德国、法国和澳大利亚。此外，美国还发表了最多数量的随机对照试验（260）、最高的总影响因子（27206.55）和最高的总引用数（84170）。当按人口规模标准化时，澳大利亚的每百万人口文章数最高，其次是荷兰、瑞士、奥地利和比利时。
美国是重症监护医学亚专业最具生产力的国家。当按人口规模标准化时，澳大利亚和一些欧洲国家的生产力可能更高。
