To construct a prenatal care information platform based on "Five-color Management" to improve the health of pregnant women.

From January to February 2018, we selected 152 pregnant women under perinatal care in obstetrical outpatient department and 138 medical workers in obstetrical department at three Class Ⅲ hospitals in He'nan as subjects. Platform contents and functions were determined by literature review, questionnaire survey and expert group meeting. Questionnaire survey adopted the method of convenience sampling.

The recovery rate of the pregnant women version and doctor-nurse version of platform content and function demands questionnaire was 97.37% and 98.57% respectively. The plan first draft was developed based on questionnaire survey.
