目的：探讨准实验设计在医疗质量改进研究中的应用。这篇文章的目标群体是调查计划做研究行动（PDSA）质量改进的举措，谁希望提高他们的方法的严谨性，并公布他们的工作和评论家谁评估的研究建议或发表work.Summary的质量：PDSA质量改进研究的主要目的是建立一个功能之间的关系，在系统的医疗保健和结果的变化过程中的变化。时间序列设计是展示这种函数关系的基本范式。PDSA质量改进研究设计的严谨性得到加强，使用复制方案和研究方法，以解决外部因素，削弱有效性的观察studies.Conclusion：PDSA质量改进研究的设计应遵循的目的和背景下的项目。提高质量改进文献的严谨性将为医疗保健质量改进的研究和实践建立更坚实的基础和更令人信服的理由。
Objective:The purpose of this article is to discuss strengths and weaknesses of quasi-experimental designs used in health care quality improvement research. The target groups for this article are investigators in plan-do-study-act (PDSA) quality improvement initiatives who wish to improve the rigor of their methodology and publish their work and reviewers who evaluate the quality of research proposals or published work.Summary:A primary purpose of PDSA quality improvement research is to establish a functional relationship between process changes in systems of health care and variation in outcomes. The time series design is the fundamental paradigm for demonstrating such functional relationships. The rigor of a PDSA quality improvement study design is strengthened using replication schemes and research methodology to address extraneous factors that weaken validity of observational studies.Conclusion:The design of PDSA quality improvement research should follow from the purpose and context of the project. Improving the rigor of the quality improvement literature will build a stronger foundation and more convincing justification for the study and practice of quality improvement in health care.
