Physicians often scan a select number of journals to keep up to date with practice evidence for patients with kidney conditions. This raises the question of where relevant studies are published. We performed a bibliometric analysis using 195 renal systematic reviews. Each review used a comprehensive method to identify all primary studies for a focused clinical question relevant to patient care. We compiled all the primary studies included in these reviews, and considered where each study was published. Of the 2779 studies, 1351 (49%) were published in the top 20 journals. Predictably, this list included Transplantation Proceedings (5.9% of studies), Kidney International (5.3%), American Journal of Kidney Diseases (4.7%), Nephrology Dialysis Transplantation (4.3%), Transplantation (4.2%), and Journal of the American Society of Nephrology (2.4%). Ten non-renal journals were also on this list, including New England Journal of Medicine (2.4%), Lancet (2.3%), and Diabetes Care (2.2%). The remaining 1428 (51%) studies were published across other 446 journals. When the disciplines of all journals were considered, 59 were classified as renal or transplant journals (42% of articles). Other specialties included general and internal medicine (16%), endocrinology (diabetes) and metabolism (6.5%), surgery (6.2%), cardiovascular diseases (6.1%), pediatrics (4.3%), and radiology (3.3%). About half of all renal practice evidence is published in non-renal journals. Browsing the top journals is important. However, relevant studies are also scattered across a large range of journals that may not be routinely scanned by busy physicians, and keeping up with this literature requires other continuing education strategies.
医生们经常浏览一些特定的期刊，以了解肾脏病患者的实践证据并跟上最新进展。这就引出了相关研究在何处发表的问题。我们使用195篇肾脏系统评价进行了文献计量分析。每项评价都采用了全面的方法来识别与患者护理相关的特定临床问题的所有原始研究。我们汇总了这些评价中包含的所有原始研究，并考虑了每项研究的发表位置。在2779项研究中，1351项（49%）发表在排名前20的期刊上。不出所料，这份名单包括《移植会议录》（占研究的5.9%）、《国际肾脏病杂志》（5.3%）、《美国肾脏病杂志》（4.7%）、《肾脏病透析移植杂志》（4.3%）、《移植杂志》（4.2%）和《美国肾脏病学会杂志》（2.4%）。还有10种非肾脏期刊也在这份名单上，包括《新英格兰医学杂志》（2.4%）、《柳叶刀》（2.3%）和《糖尿病护理》（2.2%）。其余1428项（51%）研究发表在其他446种期刊上。当考虑所有期刊的学科时，59种被归类为肾脏或移植期刊（占文章的42%）。其他专业包括普通内科和内科（16%）、内分泌学（糖尿病）和代谢（6.5%）、外科（6.2%）、心血管疾病（6.1%）、儿科学（4.3%）和放射学（3.3%）。大约一半的肾脏实践证据发表在非肾脏期刊上。浏览顶级期刊很重要。然而，相关研究也分散在大量忙碌的医生可能不会经常浏览的期刊中，跟上这些文献需要其他继续教育策略。
