Background: Anxiety and depression are the most prevalent psychiatric diseases in the peripartum period. They can lead to relevant health consequences for mother and child as well as increased health care resource utilization (HCRU) and related costs. Due to the promising results of mindfulness-based interventions (MBI) and digital health applications in mental health, an electronic MBI on maternal mental health during pregnancy was implemented and assessed in terms of transferability to standard care in Germany. The present study focused the health economic outcomes of the randomized controlled trial (RCT). Methods: The analysis, adopting a payer's and a societal perspective, included women of increased emotional distress at < 29 weeks of gestation. We applied inferential statistics (α = 0.05 significance level) to compare the intervention group (IG) and control group (CG) in terms of HCRU and costs. The analysis was primarily based on statutory health insurance claims data which covered the individual observational period of 40 weeks. Results: Overall, 258 women (IG: 117, CG: 141) were included in the health economic analysis. The results on total health care costs from a payer's perspective indicated higher costs for the IGi compared to the CG (Exp(ß) = 1.096, 95% CI: 1.006–1.194, p = 0.037). However, the estimation was not significant after Bonferroni correction (p < 0.006). Even the analysis from a societal perspective as well as sensitivity analyses did not show significant results. Conclusions: In the present study, the eMBI did neither reduced nor significantly increased health care costs. Further research is needed to generate robust evidence on eMBIs for women suffering from peripartum depression and anxiety. Trial registration: German Clinical Trials Register: DRKS00017210.
