NICE recommends that GPs should ask two questions to screen for depression at the postnatal check. A recent audit in our practice found that an assessment of mental health was documented in the records of only 31% of our postnatal women, and we have therefore decided to send out the two-question screen with our postnatal check invitations. Although postnatal depression tends to remit spontaneously at 4-6 months, it leads to considerable distress and disruption, and treatment doubles the recovery rate. Screening and treatment is therefore entirely justified.
