Nationwide epidemiological data on pregnancy and childbirth was lacking in China during the last decades. Since the establishment of the national data monitoring network and the booming of regional epidemiological studies, more information has emerged. The results and suggestions from the China Labor and Delivery Survey are crucial for improving current clinical practices. Researches that are conducted based on national data monitoring network and hospital-based medical history system, and multicenter clinical trials will provide plenty of useful evidences. These high-quality evidences would further improve clinical practice and development of obstetrics in China.
我国长期以来缺乏全国水平的妊娠与分娩相关的流行病学数据。近年来，国家数据监测中心的建立及地区流行病学调查的开展，为我国提供了宝贵的产科疾病资料。《全国分娩调查》项目更是为指导并改善我国当前的产科实践提供重要的参考依据。今后，基于国家地区数据监测网络和医院电子化病历系统开展的临床研究，以及高质量的多中心临床试验，将为我国产科学科建设和临床实践持续改进提供更多有价值的循证医学证据。.
