Six Countries, Six Guidelines: What the World Agrees (and Disagrees) On for Perinatal Depression Screening
- Comparative review of perinatal depression screening guidelines from 6 countries — first systematic cross-national comparison of screening, diagnosis, and management recommendations
- Universal agreement: screen all pregnant and postpartum women. EPDS (Edinburgh Postnatal Depression Scale) recommended across all 6 guidelines as primary screening tool
- Key disagreements: when to screen (trimester-specific vs single screening), screening frequency (once vs repeated), who should screen (OB/midwife vs primary care), and treatment thresholds
- Only 2 of 6 guidelines provide specific guidance on screening during pregnancy (not just postpartum) — a significant gap
Every practitioner working with perinatal patients knows they should screen for depression. But how, when, and what to do with the result varies dramatically by country. This European Journal of Obstetrics review puts six national guidelines side by side — and the disagreements are as informative as the consensus.
Where guidelines agree
The EPDS remains the universally endorsed screening tool. All six guidelines recommend universal screening (not just high-risk populations). All recognise that perinatal depression affects both mother and child development. These are no longer debatable points.
Where they diverge
Timing is the biggest disagreement. Some guidelines recommend screening in each trimester plus postpartum. Others recommend a single postpartum screen. Only two of six address antenatal screening with specific guidance — despite evidence that depression during pregnancy is as prevalent and consequential as postpartum depression.
Treatment thresholds also diverge. At what EPDS score do you refer? Do you refer to a psychiatrist, a psychologist, or primary care with enhanced monitoring? The answers differ by country, reflecting different healthcare system structures rather than different evidence.
For your practice
If you screen for perinatal depression, this review gives you the most current international benchmark. Use it to evaluate whether your practice's protocol covers the gaps: antenatal screening (not just postpartum), repeated screening (not just once), and clear referral pathways at defined thresholds.
All six national guidelines agree on universal EPDS screening for perinatal depression — but disagree on when, how often, and what score triggers referral. The gaps are as important as the consensus.
