An intervention built around telephone calls doubled the share of postpartum women who attended a primary care visit within a year of delivery and meaningfully improved their blood pressure control, according to a randomized trial published this month in JAMA Network Open.
The trial results come from a study that enrolled 140 women who had hypertension or a hypertensive disorder of pregnancy. Among those in the intervention group, 71 percent attended a primary care visit by 12 months postpartum, compared with 39 percent of the control group, a relative risk of 2.00. Blood pressure control below 130/80 was achieved by 55 percent of the intervention group versus 31 percent of the control group.
