In 2011, Plastic and Reconstructive Surgery (PRS) implemented a level-of-evidence (LOE) pyramid to bring attention to evidence-based medicine and to promote quality of research. The objective of our study was to examine the current, overall quality of plastic surgery research when compared with that of the previous 30 years. Articles from PRS published in 2013 were culled for information, including LOE based on the assigned score from the LOE pyramid. (Animal, cadaver, and basic science studies; reviews; correspondence; and continuing medical education articles were excluded.) The LOE grades were compared with those from 1983, 1993, and 2003. In 2013, 536 articles were published in PRS; of these, 247 met the inclusion criteria and were included in the analysis. The mean LOE in PRS for 2013 was 3.42. For the year 2003, the mean LOE was 4.16; 1993, 4.25; and 1983, 4.42. Analysis of variance indicated significant improvement in research quality over time (P < 0.001). In 2014, 216 of 489 published articles met the inclusion criteria. The mean LOE of PRS articles in 2014 was 3.33, demonstrating continued higher LOE. There was also a decrease in the percentage of level IV and V studies to 47.2% (from 51.4% in 2013), whereas higher quality level I and II studies had increased to 18.1% (from 17.4%). The quality of plastic surgery research has shown a continued upsurge as evidenced by overall improvement in LOE in published articles over the past 3 decades.
2011年,《整形与重建外科》(PRS)采用了证据等级(LOE)金字塔,以引起对循证医学的关注并提升研究质量。我们研究的目的是,将当前整形外科学研究的整体质量与过去30年的情况进行比较。收集了2013年发表于PRS的文章中的信息,包括基于证据等级金字塔所赋分数的证据等级。(动物、尸体和基础科学研究;综述;通信;以及继续医学教育文章被排除。)将证据等级评分与1983年、1993年和2003年的评分进行比较。2013年,PRS发表了536篇文章;其中,247篇符合纳入标准并被纳入分析。2013年PRS文章的平均证据等级为3.42。2003年的平均证据等级为4.16;1993年为4.25;1983年为4.42。方差分析表明,研究质量随时间有显著提高(P < 0.001)。2014年,489篇发表文章中有216篇符合纳入标准。2014年PRS文章的平均证据等级为3.33,表明证据等级持续较高。IV级和V级研究的百分比也降至47.2%(从2013年的51.4%),而更高质量的I级和II级研究增加到18.1%(从17.4%)。整形外科学研究的质量持续上升,过去30年发表文章的证据等级总体提高证明了这一点。
