Cardiovascular disease and hypertensive disorders of pregnancy (HDP) are the leading causes of maternal morbidity and mortality in the United States. Postpartum, in office care has demonstrated to be an insufficient model of hypertensive management postpartum, largely due to barriers that women face in accessing in office care, with stark racial disparities in access. The care of postpartum patients with HDP following delivery is made up of either a single postpartum visit at 6 weeks postpartum or a fragmented and non-standardized series of in-person appointments depending on the patients' medical complications and the clinicians' experience. Further, current society guidelines outline inpatient thresholds for initiation of antihypertensive medication but do not provide recommendations for titration thereafter. The proposed study will investigate the acceptability and effectiveness of an algorithm-based, outpatient treatment model for the management of postpartum hypertension utilizing an asynchronous text-based platform as compared to the standard of care for postpartum women with a diagnosis of Hypertensive disorder of pregnancy at Massachusetts General Hospital.
