Evidence-based medicine (EBM) emphasizes the combination of the physician's experience, the best research evidence and patient's values to ensure the best prevention and treatment effect. Evidence is the core of the EBM, and quantitative systematic review can synthesize interventional studies; however, it can't provide synthetic evidence for patients' demands, opinions and attitudes and so on. Qualitative systematic review can offset these limitations. With the development of methodology of qualitative research and systematic review of qualitative studies, the number of qualitative studies increased year by year and they provided more and more evidence for decision making in public health, social work, management and education. The international research institutions including the Cochrane Collaboration, the Campbell Collaboration and the 3ie have mature methods for qualitative systematic review; however, few studies introduced how to write it in China. Therefore, this paper briefly introduces how to write the qualitative systematic review.
