Abstract：
The aim of this study was to identify current research on turning frequencies of adult bed-bound patients and inform future turning practices for hospitals based on evidence-based practice. We undertook a scoping review framework that provided a transparent and systematic methodology using 8 electronic databases (CINAHL, PubMed, Cochrane Library, ScienceDirect, PsycINFO, Scopus, ProQuest, and Web of Science) to identify articles published from 2000 to 2016. Articles were included if they focused on the prevention of hospital-acquired pressure ulcers related to the frequency of turning or repositioning of bed-bound patients. Literature search and data extraction were performed independently by 3 authors. The study followed the PRISMA guidelines. In total, 911 articles were identified, of which 10 were eligible. Of the eligible articles, 8 studies could not reach a conclusion on the effective frequency of turning and duration for repositioning patients to prevent the development of pressure ulcers. Only 2 studies found significant differences among the intervention and control groups. Results regarding turning and repositioning schedules are inconclusive; however, the topic needs further exploration to improve the outdated guidelines surrounding pressure ulcer prevention. This may, in turn, make the work of nurses more efficient and make treatment cost-effective for both the patients and the hospitals.
摘要：
这项研究的目的是确定当前有关成人卧床患者转弯频率的研究，并根据循证实践为医院的未来转弯实践提供信息。我们进行了范围审查框架，该框架使用8个电子数据库（CINAHL，PubMed,科克伦图书馆,ScienceDirect,PsycINFO,Scopus,ProQuest,和WebofScience)，以确定2000年至2016年发表的文章。如果将重点放在预防与卧床患者的转位或重新定位频率有关的医院获得性压疮，则包括这些文章。由3名作者独立进行文献检索和数据提取。这项研究遵循了PRISMA指南。总的来说,911文章被确认，其中10人符合资格。在符合条件的文章中，8项研究未能得出关于重新定位患者以预防压疮发展的有效转动频率和持续时间的结论。只有2项研究发现干预组和对照组之间存在显著差异。有关转弯和重新定位计划的结果尚无定论；但是，该主题需要进一步探索，以改进围绕压疮预防的过时指南。这可能,反过来,使护士的工作更有效率，使治疗对患者和医院都具有成本效益。
