Abstract: Objective: To develop an intelligent follow-up information platform for comprehensive maternal-perinatal healthcare and to evaluate its application effects, so as to provide a reference for improving maternal and child health care services. Methods: An intelligent follow-up information platform for comprehensive maternal-perinatal healthcare was developed through literature review and semi-structured interviews. Using a convenience sampling method, a total of 225 pregnant women who completed the entire health management process in a tertiary grade A hospital in Tianjin from April to June 2022 were recruited and assigned to the control group and followed up by a third-party App. Another 245 pregnant women admitted from October to December 2023 were recruited and assigned to the intervention group and followed up through the intelligent follow-up information platform. The duration of the intervention period was 11 months. Compare the health outcome indicators of mothers and infants, quality indicators of antenatal and intrapartum management, and satisfaction rate between the two groups before and after the intervention, and evaluate platform usability. Results: The following outcomes of participants in the intervention group were significantly better than those in the control group: natural delivery rate, pelvic floor function screening rate, knowledge level, coverage rate of high-risk pregnant women under platform management, follow-up rate of pregnancy complications, and satisfaction rate (all P<0.05). Besides, the following outcomes of participants in the intervention group were significantly lower than those in the control group: postpartum hemorrhage, incidence of macrosomia, and follow-up duration (all P<0.05). The platform usability scores of both nursing staff and the intervention group participants were above 70. Conclusion: The application of the intelligent follow-up information platform for comprehensive maternal healthcare has improved the efficiency of perinatal management and service quality. With good usability, it holds significant value for clinical promotion.
