THIRTY-nine per cent of children admitted to Hong Kong's residential creche homes, for infants under the age of two, had been abandoned, a new study has revealed. The Hong Kong Family Welfare Society has called for urgent emergency care places for children, following the release of the Hong Kong University Social Welfare Department's study. The society's director, Thomas Mulvey, said children admitted to all types of residential care were there for family-related reasons, such as marital discord or parental illness. Residential care includes foster homes, nurseries, creches, children's homes and small group homes. Mr Mulvey said that of the 277 children placed in residential creches, 39 per cent had been abandoned. Two-thirds of children admitted to residential care were from single parent families. Mr Mulvey has called for more emergency care places for children and long-term foster care as the best solution to abandoned children. ''I certainly think that the children who are in residential nurseries and residential creches should be in foster homes unless there is a very specific reason why they are better off in a residential creche,'' he said. ''In terms of the children in residential nurseries or residential creches where they don't have contact with their parents, the children should be looked at in terms of adoption.'' Mr Mulvey said the Social Welfare Department would use emergency foster care for non-statutory child care cases from next week, but he called for all children to have access to the care. He said the society's survey of the demand for emergency care revealed that non-government agencies operating family services had identified 35 children who required emergency foster care during an eight-month period. Thirty-two of the children were under the age of 12 and almost half required immediate admission. The Social Welfare Department revealed that in a nine-month period, 11 children, all under 10, required emergency care. The reasons for which they were admitted were parental illness or parents ''being inadequate''. The society has received 34 inquiries for help since it started an emergency foster care programme in May this year.
