Objective: To test the ability of a hospital-wide, bundled quality-improvement initiative to improve postpartum maternal blood pressure control and adherence to postpartum follow-up among patients with hypertensive disorders of pregnancy.Methods: This quality-improvement initiative consisted of a bundle of clinical interventions including health care professional and patient education, a dedicated nurse educator, and protocols for postpartum hypertensive disorders of pregnancy care in the inpatient, outpatient and readmission setting. We implemented this initiative in patients with hypertensive disorders of pregnancy starting in January 2019 at the University of Chicago. The study period was divided into four periods, which correspond to preintervention, distinct bundle roll outs, and postintervention. Our primary outcome was postpartum hypertension visit adherence. Secondary outcomes included blood pressure values and antihypertensive medication use in the immediate postpartum and outpatient postpartum time periods. We then stratified our outcomes by race to assess whether the effect size differed.Results: A total of 926 patients who delivered between September 2018 and November 2019 were included. Postpartum hypertension visit adherence improved from preintervention period compared with the full implementation period (33.5% vs 59.4%, P<.001). Blood pressure in the first 24 hours postpartum decreased from preintervention compared with full implementation (preintervention median [interquartile range] systolic blood pressure 149 mm Hg [138, 159] vs 137 [131, 146] in postimplementation; P<.001). After implementation, fewer patients experienced a blood pressure of 140/90 mm Hg or higher at the first postpartum blood pressure check, when compared with preintervention (39.1% vs 18.5%, P=.004). The effect size did not differ by race.Conclusion: A bundled quality-improvement initiative for patients with hypertensive disorders of pregnancy was associated with improved postpartum visit adherence and blood pressure control in the postpartum period.
