Abstract
OBJECTIVE: To test whether treatment of mild chronic hypertension (CHTN) in pregnancy is associated with lower rates of unplanned maternal healthcare utilization postpartum.
METHODS: This was a secondary analysis of the CHTN and pregnancy (CHAP) study, a prospective, open-label, pragmatic, multicenter, randomized treatment trial of pregnant people with mild chronic hypertension. All patients with a postpartum follow-up assessment were included. The primary outcome was unplanned healthcare utilization, defined as unplanned postpartum clinic visits, Emergency Department or triage visits, or unplanned hospital admissions within six weeks postpartum. Differences in outcomes were compared between study groups (Active Group: blood pressure goal of<140/90 mm Hg, and Control Group: blood pressure goal of <160/105 mm Hg) and factors associated with outcomes were examined using logistic regression.
RESULTS: A total of 2,293 patients were included with 1,157 (50.5%) in the active group and 1,136 (49.5%) in the control group. Rates of unplanned maternal postpartum health care utilization did not differ between treatment and control groups, (20.2% vs 23.3%, p=0.07, aOR 0.84, 95% CI 0.69-1.03. However, Emergency Department or triage/maternity evaluation unit visits were significantly lower in the Active group (10.2% vs 13.2%, p=0.03, aOR 0.76, 95% 0.58-0.99). Higher BMI at enrollment and cesarean delivery were associated with higher odds of unplanned postpartum healthcare utilization.
CONCLUSION: While treatment of mild CHTN during pregnancy and postpartum was not significantly associated with overall unplanned healthcare resource utilization, it was associated with lower rates of postpartum Emergency Department and triage visits.
