People of Chinese ethnicity are the largest population in the world. Critical care medicine in China is developing rapidly and has achieved great advances in recent 20 years. The research contribution in critical care medicine among Chinese individuals in the three major regions of China--Mainland (ML), Hong Kong (HK), and Taiwan (TW)--is unknown.
Articles published in 18 journals on critical care medicine originating from ML, TW, and HK from 1999 to 2008 were retrieved from the PubMed database and Science Citation Index Expanded. Quantity and quality analyses were conducted for the total numbers of articles, clinical trials, randomized controlled trials, impact factors (IF), citations, and articles published in high-impact journals.
There were 932 articles from ML (268), TW (506), and HK (158) from 1999 to 2008. The annual total numbers of articles of the three regions increased gradually from 1999 to 2008 (from 57 to 157). From 2002 onward, the number of articles published from ML exceeded that from HK, but TW still has the dominance in both annual and total number of articles published compared with ML and HK. The accumulated IF of articles from TW (1676.67) was higher than that from ML (708.25) and HK (449.51). TW had the highest average IF of 3.31 followed by HK of 2.85 and ML of 2.64. HK had the highest average citations of each article of 10.73, followed by TW of 6.74 and ML of 5.34. The Journal of Trauma was the most popular journal in the three regions.
The total numbers of articles in China increased markedly from 1999 to 2008. TW published the most number of articles, clinical trials, and randomised controlled trials among the three regions. The Journal of Trauma was the most popular journal in the three regions.
华裔是世界上人口最多的群体。中国的重症医学发展迅速，在最近20年里取得了巨大进步。中国三个主要地区——中国大陆（ML）、香港（HK）和台湾（TW）——的华人在重症医学领域的研究贡献尚不清楚。
从PubMed数据库和科学引文索引扩展版中检索1999年至2008年发表在18种重症医学期刊上的来自ML、TW和HK的文章。对文章总数、临床试验、随机对照试验、影响因子（IF）、引用次数以及在高影响因子期刊上发表的文章进行了数量和质量分析。
1999年至2008年，有来自ML的932篇文章（268篇）、TW的（506篇）和HK的（158篇）。三个地区的文章年总数从1999年到2008年逐渐增加（从57篇增至157篇）。从2002年起，ML发表的文章数量超过了HK，但与ML和HK相比，TW在年发表文章数和总发表文章数方面仍占主导地位。TW文章的累计影响因子（1676.67）高于ML（708.25）和HK（449.51）。TW的平均影响因子最高，为3.31，其次是HK的2.85和ML的2.64。HK每篇文章的平均引用次数最高，为10.73，其次是TW的6.74和ML的5.34。《创伤杂志》是这三个地区最受欢迎的期刊。
1999年至2008年中国的文章总数显著增加。在这三个地区中，TW发表的文章、临床试验和随机对照试验数量最多。《创伤杂志》是这三个地区最受欢迎的期刊。
