Does an individualized case management model improve blood pressure control and pregnancy outcomes in pregnant women with gestational hypertension?
A WeChat-based individualized case management model significantly improved blood pressure control and reduced preterm births and pregnancy complications in women with gestational hypertension.
Effect estimate: MD -7.4 mmHg

Objective This study aimed to evaluate the effectiveness of a case management model in the comprehensive management of gestational hypertension, focusing on its impact on blood pressure control, pregnancy complications, neonatal health, and maternal satisfaction. Methods A randomized controlled trial was conducted, enrolling 100 pregnant women with hypertension who attended the high-risk outpatient clinic of our hospital from March 2023 to March 2025. Participants were randomly assigned to either an experimental group ( n = 50), which received a case management model intervention, or a control group ( n = 50), which received standard prenatal care. The two groups were compared regarding blood pressure control, incidence of pregnancy complications, gestational age at delivery, preterm birth rate, birth weight, low birth weight incidence, neonatal transfer rate, and maternal satisfaction. Statistical analyses were conducted using SPSS 23.0, with a significance level of P 0.05. Results The experimental group showed significantly better blood pressure control, with lower systolic and diastolic blood pressure levels compared to the control group ( P 0.05). The incidence of pregnancy complications, such as preeclampsia, placental abruption, and Hemolysis, Elevated Liver Enzymes, and Low Platelet count (HELLP) syndrome, was significantly reduced in the experimental group ( P 0.05). Additionally, the experimental group had an extended gestational age at delivery, a lower preterm birth rate, and higher birth weight ( P 0.05). Neonatal outcomes were improved, as evidenced by a significant reduction in the incidence of low birth weight and neonatal transfer rates ( P 0.05). Maternal satisfaction with care was also significantly higher in the experimental group ( P 0.01). Conclusion The case management model significantly improved maternal and neonatal outcomes by enhancing blood pressure control, reducing pregnancy complications, and increasing maternal satisfaction. These results support the integration of case management into standard care for pregnant women with hypertension to optimize pregnancy outcomes.
Tang et al. (Fri,) conducted a rct in Gestational hypertension (n=100). Case management model vs. Standard prenatal care was evaluated on Systolic blood pressure (mmHg) (MD -7.4 mmHg, p=0.002). The case management model significantly reduced systolic blood pressure by 7.4 mmHg compared to standard prenatal care in pregnant women with hypertension.
