循证医学中PICO模型的扩展及其在定性研究中的应用

Expansion of PICO Model in Evidence-based Medicine and Its Application in Qualitative Research

PICO模型是循证医学中构建问题的通用模型,然而随着医学研究的不断深入、细化及定性研究的兴起,PICO模型已经不能满足全部医学问题的构建。因此,本文在PICO模型的基础之上对其进行了扩展,并针对定性研究介绍了SPIDER模型,从而使临床工作者能在短时间内构建出临床问题,并为问题的检索提供最佳策略。

The PICO model is a general model in building problems of evidence-based medicine （EBM）. However, with the deepening and refinement of the medical research and the rising of qualitative research, the PICO model could not satisfy all problems. This article introduces the expansions of the PICO model and puts forward the SPIDER model according to the qualitative problem and its relationship with the PICO model, which can build the best search strategy of clinical problems in a short time.
