Abstract:Objective：To analyze the referral data of high-risk pregnant women，understand the distribution and outcome of the disease，and from the perspective of process management theory，summarize the referral experience from three aspects：mechanism construction before referral，standard diagnosis and treatment in the referral process，and experience summary after discharge. Methods：The clinical data of 1430 high-risk pregnant and lying-in women who were transferred to the certain hospital through outpatient and emergency services from 2020-2021 were retrospectively analyzed，and the age of the patients，the gestational weeks of referral，the distribution of disease types，and the selection of operation methods were statistically analyzed. Results：The average age of referral was 29.9 ± 5.2 years old，and the average gestational age of referral was 24.6 ± 10.0 weeks；The distribution of diseases was as follows：pregnancy complications（40.2%），pregnancy with uterine scar（23.4%），fetal appendage anomalies（15.0%），pregnancy with non-obstetric diseases（5.2%），and pregnancy supervision（4%）；Operation type selection：Of 1430 referral patients，cesarean section accounted for 56.3%，spontaneous delivery accounted for 29.5%，pregnancy supervision accounted for 8.8%，postpartum referral accounted for 1%，spontaneous abortion and other postoperative patients accounted for 4.4%；66.3% were cured，32.4% improved，1.0% were transferred to other departments，and 0.3% were not cured. Conclusion：The early referral and standardized treatment of high-risk pregnant and lying-in women is the key to reduce the mortality rate of pregnant and lying-in women and perinatal infants. We should improve the referral network of pregnant and lying-in women in urban and rural areas，summarize and promote experience in time，and improve the treatment ability.
