Predictors of social services supervision of babies of mothers with mental illness after admission to a psychiatric mother and baby unit

Background. There is insufficient information on the predictors of parenting difficulties in mothers with severe mental illness. Using data from mother and baby units in the UK we aimed to examine the social and clinical characteristics of mothers whose babies were supervised by social services on discharge. Method. A case-control study was carried out using data from mother and baby units and facilities entered onto the Marce database. Results. Of 1197 mothers, 23% were discharged with their babies under some form of social services supervision. Factors independently associated with an increased risk of supervision included social class (OR 3.16, 95% CI 1.99-5.03), single marital status (OR 2.10, 95% CI 1.38-3.20), behavioural disturbance (OR 1.69, 95% CI 1.08-2.65) and psychiatric illness in the partner (OR 2.67,95% CI 1.59-4.49). The diagnostic groups independently associated with the highest risk of having a supervised baby were schizophrenia (OR 5.16, 95% CI 2.61-10.21) and personality disorder (OR 9.29, 95% CI 3.46-24.91). Conclusions. Mothers with schizophrenia are at particularly high risk of having their baby supervised by social services. Preventative interventions should be targeted at socio-economic difficulties, early detection of psychiatric disorders postpartum and treatment of perinatal mental illness in the context of the whole family.
