Despite widespread engagement in quality improvement activities, little is known about the designs of studies currently published in quality improvement journals. This study's goal is to establish the prevalence of the types of research conducted in articles published in journals dedicated to quality improvement. A cross-sectional analysis was performed of 145 research articles published in 11 quality improvement journals in 2011. The majority of study designs were considered pre-experimental (95%), with a small percentage of quasi-experimental and experimental designs. Of the studies that reported the results of an intervention (n = 60), the most common research designs were pre-post studies (33%) and case studies (25%). There were few randomized controlled trials or quasi-experimental study designs (12% of intervention studies). These results suggest that there are opportunities for increased use of quasi-experimental study designs.
尽管质量改进活动广泛开展，但对于目前发表在质量改进期刊上的研究设计却知之甚少。本研究的目的是确定在专门致力于质量改进的期刊上发表的文章中所进行的研究类型的普遍性。对2011年发表在11种质量改进期刊上的145篇研究文章进行了横断面分析。大多数研究设计被认为是预实验性的（95%），准实验性和实验性设计的比例较小。在报告干预结果的研究中（n = 60），最常见的研究设计是前后对照研究（33%）和案例研究（25%）。随机对照试验或准实验性研究设计很少（干预研究的12%）。这些结果表明，增加准实验性研究设计的使用存在机会。
