Successful implementation of text-based blood pressure monitoring for postpartum hypertension.

Objectives: A clinical trial showed postpartum text-based blood pressure (BP) monitoring is effective in meeting clinical guidelines and reduces racial disparities in postpartum hypertension care. Our objective was to compare clinical outcomes to those from a clinical trial after implementation of the program in a second hospital within our hospital system.

Study Design: Comparison of women randomized to text-based BP monitoring in a clinical trial compared to an implementation cohort clinically enrolled in text-based BP monitoring. BP outcomes and postpartum visit were compared in bivariate and multivariable analyses.

Main Outcome Measures: BP ascertainment was defined as at least 1 BP texted during the 10 days of monitoring. American College of Obstetricians and Gynecologists (ACOG) recommendation was defined as BP sent on postpartum day 3-4 and again day 7-10.

Results: The implementation cohort had 333 women compared to 103 in the trial cohort. The implementation cohort was older (p < 0.001), and more likely to be non-Black race (p < 0.001), married (<0.001), and have commercial insurance (<0.001). BP ascertainment (95.5% vs. 92.2%, adjusted OR 1.41, [95% CI 0.55, 3.58]) and proportion meeting ACOG recommendations (84.7% vs. 81.6%, adjusted OR 0.89 [95% CI 0.48, 1.64]) were similar between groups. There were no differences in BP ascertainment among Black and non-Black women in the trial or implementation cohort.

Conclusions: Text-based BP monitoring performed similarly in an implementation cohort compared to the trial participants. This program is scalable to manage postpartum hypertension and reduce racial disparities in postpartum care in women with hypertensive disorders of pregnancy.
