The continued care of pregnant women receiving opiate substitution treatment by midwives.

Background: The care of pregnant women receiving opiate substitution treatment (OST) is generally provided by a variety of health care professionals. Midwives working in prenatal consultations take part in this continued care and may meet with their patients several times throughout the pregnancy, which can have a tremendous impact on monitoring. The purpose of the study was to determine whether midwives are used to accompanying women taking OST and to determine their level of knowledge and investment in this area.
