This systematic review and meta-analysis pooled randomized controlled trials of digital health interventions for postpartum women who had experienced pregnancy- or childbirth-related trauma. Ten trials involving 1026 participants were included. Across 9 trials (809 participants), interventions were associated with lower PTSD symptom severity immediately after treatment (SMD -0.59, 95% CI -0.98 to -0.19; P=.01), but heterogeneity was substantial (I²=79.86%). At the longest available follow-up, the pooled effect was not statistically significant. The authors also reported possible short-term reductions in depressive and anxiety symptoms, while emphasizing uncertainty in the evidence.
Key findings
- Immediately after intervention, PTSD symptom severity was lower with digital interventions (SMD -0.59, 95% CI -0.98 to -0.19; P=.01; I²=79.86%).
- At longest available follow-up, the PTSD symptom effect was not statistically significant (SMD -0.36, 95% CI -1 to 0.27; P=.20).
- All 95% prediction intervals crossed the null, limiting confidence that effects would be consistent across settings.
- An exploratory subgroup difference by health care provider involvement was statistically significant (Q=14.46; P<.001), but requires cautious interpretation.
Why it matters
Postpartum PTSD symptoms after traumatic pregnancy or childbirth can affect women and families, while access to psychological support may be limited. This synthesis suggests digital interventions could offer short-term symptom benefit, but substantial between-trial variation and uncertain follow-up effects mean the pooled estimate should not be treated as a dependable prediction for every population or program.
What to keep in mind
The evidence showed substantial heterogeneity, and all prediction intervals crossed the null. The pooled follow-up effect was not statistically significant, and the abstract notes that longer follow-up and clinically interpretable outcomes are needed.
