Telehealth Strategies for the Delivery of Maternal Health Care: A Rapid Review


PCORI commissioned a rapid review to assess evidence on the effectiveness of telehealth strategies for the delivery of maternal healthcare. Because telemedicine has experienced a swift and widespread adoption in the United States, PCORI sought to understand the evidence base on a compressed timeline in order to inform our future research investments.

The evidence synthesized in this rapid review indicates that telehealth for maternal health care delivery is a promising alternative and/or supplement to usual, in-person care. Equally important are the evidence gaps identified in this review that point us to future research priorities. Full results of this rapid review are also available in the Annals of Internal Medicine.

Study Results that Support Better-Informed Decisions


Testing the Effectiveness of Adding Group Therapy to Home Visiting Services on Reducing Postpartum Depression in Women with Low Incomes: A Randomized Controlled Trial

Adding a group therapy program called Mothers and Babies to home visiting services did not reduce depressive symptoms in perinatal women more than home visiting services alone, according to this PCORI-funded research study.

However, group therapy led by a community health worker was comparably effective as group therapy led by a mental health professional in reducing depressive symptoms. The study included 824 perinatal women enrolled in 37 home visiting programs in seven midwestern states. The trial results were published in the Archives of Women’s Mental Health in March 2021.

Read more about the study in this PCORI Story and watch a video interview with Darius Tandon, the study’s Principal Investigator, in which he shares more about his study and reasons why women are not receiving care for postpartum depression.
