Postpartum navigation raised the care received, not the all-or-nothing target

Design

Single-centre randomised clinical trial, navigation vs usual care for one year

Population

405 pregnant people aged 16 or over with Medicaid insurance (203 navigation, 202 usual care)

Primary outcome

Receipt of all 6 essential postpartum care components by 12 weeks

Effect

9.4% vs 7.9% (P = 0.60); mean proportion of components 71% vs 64% (P = 0.002)

This single-centre US trial randomised 405 pregnant people aged 16 or over with Medicaid insurance to one year of postpartum patient navigation from a trained lay navigator or to usual care. The primary outcome was receipt of all six care elements judged essential to postpartum care by 12 weeks.

The primary outcome was uncommon in both groups and did not differ: 19 of 203 (9.4%) with navigation vs 16 of 202 (7.9%) with usual care (P = 0.60). The mean proportion of the six components received was higher with navigation (71% vs 64%, P = 0.002). Three elements drove it: completing the postpartum visit (96% vs 80%), receiving all indicated anticipatory guidance (65% vs 51%) and depression screening and care (86% vs 72%). At 11 to 13 months, the navigation group was more likely to have attended primary care, to be using their preferred family planning method and to have had depression screening, cardiometabolic screening and vaccines.

The trial was at one urban academic centre in the United States, and outcomes were taken from medical records. Nothing here measures health outcomes such as depression or blood pressure. Where family doctors share postpartum care, the finding suggests a link person can help women reach follow-up.

• Make sure postpartum women have a booked visit and know who to contact; completion rose most with navigation.
• Ask about mood at the postpartum visit and arrange follow-up for those who screen positive.
• Use the postpartum contact to start primary care follow-up: blood pressure, glucose after gestational diabetes, vaccines and contraception.
• Consider a community health worker or practice nurse as a navigator where one is available.

Why it matters

It shows an intervention can improve most steps of care and still miss a demanding composite outcome.

Don't overread it

Navigation did not raise the primary all-six outcome, and the study measured care received, not maternal health outcomes.

The statistics, in plain English

The all-six outcome was reached by fewer than one in ten in both groups, so the study could not show a difference for it. The component average moved from 64% to 71%, which is a modest absolute gain that reflects mainly better visit attendance, guidance and depression care.
