Women with hypertensive disorders of pregnancy need postpartum blood pressure (BP) surveillance to detect persistent hypertension. Various barriers result in only 30% attendance at postpartum BP visits. A more effective strategy is needed. Women with hypertension of pregnancy will be randomized to either text-based monitoring or office visits. Those randomized to the intervention will receive a BP cuff and text in their BP to an automated, clinician derived, HIPAA compliant text-based algorithm.
