复杂干预的设计和评价

Development and evaluation of complex intervention

介绍复杂干预研究的设计及过程,探索其在医学实践中的应用.在经典的干预性研究中,干预措施较为单一且效果评价较为简单.而目前越来越多的研究涉及到多个干预措施的综合,诸如心血管病的社区干预、卒中单元治疗等,此时复杂干预研究设计就较为适用.但复杂干预的设计、实施难度较大,效果评价也较困难.因此,复杂干预研究在设计、实施、评价和报告时,应严格遵守一定的标准,确保干预措施效果和研究的可重复性.

Experimental studies with only one intervention are not always sufficient for health care issnes, while the method of complex intervention is more useful. But the complex intervention is more complicated and needs carefully design and evaluation. This article will introduce the framework for design and evaluation of complex intervention and the revised version made by Medical Research Council, with five examples showing its application.
